CHAPTER1
LOGENTRY:SOL6
I’mprettymuchfucked.That’s my considered
opinion.Fucked.Six days into what should
bethegreatesttwomonthsof
mylife,andit’sturnedintoanightmare.I don’t even know who’ll
read this. I guess someonewillfinditeventually.Maybeahundredyearsfromnow.For the record…I didn’t
die on Sol 6. Certainly therestofthecrewthoughtIdid,and I can’t blame them.Maybe there’ll be a day ofnational mourning for me,and myWikipedia page will
say, “Mark Watney is theonly human being to havediedonMars.”Andit’llberight,probably.
’Cause I’ll surely die here.Just not on Sol 6 wheneveryonethinksIdid.Let’s see…where do I
begin?The Ares Program.
Mankind reaching out toMars to send people to
another planet for the veryfirst time and expand thehorizons of humanity blah,blah, blah. The Ares 1 crewdidtheirthingandcamebackheroes. They got the paradesand fame and love of theworld.Ares2did the same thing,
in a different location onMars. They got a firmhandshake and a hot cup ofcoffeewhentheygothome.
Ares 3.Well, thatwasmymission. Okay, notmine perse.CommanderLewiswasincharge. Iwas just one of hercrew.Actually,Iwastheverylowest rankedmemberof thecrew. I would only be “incommand”ofthemissionifIwere the only remainingperson.Whatdoyouknow?I’min
command.Iwonderifthislogwillbe
recovered before the rest ofthe crew die of old age. Ipresume they got back toEarth all right. Guys, ifyou’re reading this: Itwasn’tyourfault.Youdidwhatyouhad to do. In your position Iwould have done the samething.Idon’tblameyou,andI’mgladyousurvived.
Iguess I should explainhowMarsmissionswork, for any
layman who may be readingthis.WegottoEarthorbitthenormal way, through anordinary ship toHermes. AlltheAresmissionsuseHermesto get to and fromMars. It’sreally big and cost a lot soNASAbuiltonlyone.Once we got to Hermes,
four additional unmannedmissions brought us fuel andsupplies while we preparedfor our trip.Once everything
wasago,wesetoutforMars.But not very fast. Gone arethe days of heavy chemicalfuel burns and trans-Marsinjectionorbits.Hermes is powered by ion
engines. They throw argonoutthebackoftheshipreallyfast to get a tiny amount ofacceleration. The thing is, itdoesn’t take much reactantmass, soa littleargon (andanuclear reactor to power
things) let us accelerateconstantly the whole waythere. You’d be amazed athow fast you can get goingwithatinyaccelerationoveralongtime.I could regale you with
talesofhowwehadgreatfunon the trip, but I won’t. Idon’tfeellikerelivingitrightnow.Suffice it tosaywegotto Mars 124 days laterwithoutstranglingeachother.
From there, we took theMDV (Mars descent vehicle)to the surface. The MDV isbasicallyabigcanwithsomelight thrusters andparachutesattached.Itssolepurposeistoget six humans from Marsorbit to the surface withoutkillinganyofthem.And now we come to the
realtrickofMarsexploration:havingallofourshitthereinadvance.
A total of fourteenunmannedmissionsdepositedeverythingwewouldneedforsurfaceoperations.Theytriedtheir best to land all thesupply vessels in the samegeneral area, and did areasonablygoodjob.Suppliesaren’t nearly so fragile ashumans and can hit theground really hard. But theytendtobouncearoundalot.Naturally, theydidn’t send
us to Mars until they’dconfirmed that all thesupplies had made it to thesurface and their containersweren’t breached. Start tofinish, including supplymissions, a Mars missiontakes about three years. Infact, there were Ares 3supplies en route to Marswhile the Ares 2 crew wereontheirwayhome.The most important piece
of the advance supplies, ofcourse, was the MAV. TheMarsascentvehicle.Thatwashow we would get back toHermes after surfaceoperations were complete.The MAV was soft-landed(as opposed to the balloonbounce-festtheothersupplieshad). Of course, it was inconstant communicationwithHouston, and if there hadbeenanyproblemswithit,we
would have passed by Marsand gone home without everlanding.The MAV is pretty cool.
Turns out, through a neat setofchemicalreactionswiththeMartian atmosphere, forevery kilogram of hydrogenyou bring to Mars, you canmake thirteen kilograms offuel. It’s a slow process,though. It takes twenty-fourmonthstofillthetank.That’s
why they sent it long beforewegothere.You can imagine how
disappointed I was when Idiscovered the MAV wasgone.
It was a ridiculous sequenceof events that led to mealmost dying, and an evenmoreridiculoussequencethatledtomesurviving.Themission isdesigned to
handle sandstormgustsup to150 kph. So Houston gotunderstandablynervouswhenwegotwhackedwith175kphwinds.Weallgotinourflightspacesuitsandhuddledinthemiddle of the Hab, just incase it lost pressure. But theHabwasn’ttheproblem.TheMAVisaspaceship.It
has a lot of delicate parts. Itcan put up with storms to acertainextent,butitcan’tjust
getsandblastedforever.Afteran hour and a half ofsustained wind, NASA gavethe order to abort. Nobodywanted to stop a monthlongmission after only six days,but if the MAV took anymore punishment, we’d allhave gotten stranded downthere.We had to go out in the
storm toget from theHab totheMAV.Thatwasgoing to
be risky,butwhatchoicedidwehave?Everyonemadeitbutme.Our main communications
dish, which relayed signalsfrom the Hab to Hermes,actedlikeaparachute,gettingtorn from its foundation andcarried with the torrent.Along the way, it crashedthroughthereceptionantennaarray.Thenoneofthoselongthin antennae slammed into
me end-first. It tore throughmy suit like a bullet throughbutter, and I felt the worstpain of my life as it rippedopen my side. I vaguelyremember having the windknockedoutofme(pulledoutof me, really) and my earspopping painfully as thepressureofmysuitescaped.The last thing I remember
was seeing Johanssenhopelessly reaching out
towardme.
I awoke to the oxygen alarmin my suit. A steady,obnoxious beeping thateventually rousedme from adeep and profound desire tojustfuckingdie.The storm had abated; I
was facedown, almost totallyburied in sand.As I groggilycame to, I wondered why Iwasn’tmoredead.
The antenna had enoughforce to punch through thesuit and my side, but it hadbeen stopped by my pelvis.Sotherewasonlyoneholeinthesuit (andahole inme,ofcourse).I had been knocked back
quiteawaysandrolleddowna steep hill. Somehow Ilanded facedown, whichforced the antenna to astrongly oblique angle that
putalotoftorqueontheholein the suit. It made a weakseal.Then, the copious blood
from my wound trickleddowntowardthehole.Astheblood reached the site of thebreach,thewaterinitquicklyevaporated from the airflowand low pressure, leaving agunky residue behind. Moreblood came in behind it andwas also reduced to gunk.
Eventually, it sealed thegapsaround the hole and reducedtheleaktosomethingthesuitcouldcounteract.The suit did its job
admirably. Sensing the dropin pressure, it constantlyflooded itself with air frommynitrogen tank toequalize.Once the leak becamemanageable, it only had totrickle new air in slowly torelievetheairlost.
After a while, the CO2(carbondioxide) absorbers inthe suit were expended.That’s really the limitingfactortolifesupport.Nottheamount of oxygen you bringwith you, but the amount ofCO2 you can remove. In theHab,Ihavetheoxygenator,alargepieceofequipment thatbreaks apart CO2 to give theoxygen back. But the space
suits have to be portable, sothey use a simple chemicalabsorption process withexpendable filters. I’d beenasleep long enough that myfilterswereuseless.The suit saw this problem
andmovedintoanemergencymode the engineers call“bloodletting.” Having noway to separateout theCO2,the suit deliberately ventedairtotheMartianatmosphere,
thenbackfilledwithnitrogen.Between the breach and thebloodletting, it quickly ranoutofnitrogen.Allithadleftwasmyoxygentank.So it did the only thing it
could to keep me alive. Itstarted backfilling with pureoxygen. I now risked dyingfrom oxygen toxicity, as theexcessively high amount ofoxygenthreatenedtoburnupmy nervous system, lungs,
andeyes.Anironicdeathforsomeone with a leaky spacesuit:toomuchoxygen.Every step of the way
would have had beepingalarms, alerts, and warnings.But it was the high-oxygenwarningthatwokeme.The sheer volume of
trainingforaspacemissionisastounding. I’d spent aweekback on Earth practicingemergencyspacesuitdrills. I
knewwhattodo.Carefully reaching to the
side of my helmet, I got thebreach kit. It’s nothingmorethan a funnelwith a valve atthe small end and anunbelievably sticky resin onthewideend.Theideaisyouhavethevalveopenandstickthewideendoverahole.Theair can escape through thevalve, so it doesn’t interferewiththeresinmakingagood
seal. Then you close thevalve, and you’ve sealed thebreach.Thetrickypartwasgetting
theantennaoutof theway. IpulleditoutasfastasIcould,wincing as the suddenpressuredropdizziedmeandmade the wound in my sidescreaminagony.Igotthebreachkitoverthe
hole and sealed it. It held.The suit backfilled the
missing air with yet moreoxygen. Checking my armreadouts, I saw the suit wasnow at 85 percent oxygen.For reference, Earth’satmosphere is about 21percent. I’d be okay, so longas I didn’t spend too muchtimelikethat.Istumbledupthehillback
toward theHab.As I crestedtherise,Isawsomethingthatmade me very happy and
somethingthatmademeverysad: The Hab was intact(yay!) and the MAV wasgone(boo!).RightthatmomentIknewI
was screwed. But I didn’twant to just die out on thesurface. I limped back to theHab and fumbled my wayintoanairlock.Assoonas itequalized, I threw off myhelmet.Once inside the Hab, I
doffed the suit and got myfirstgoodlookattheinjury.Itwould need stitches.Fortunately, all of us hadbeen trained inbasicmedicalprocedures, and the Hab hadexcellentmedicalsupplies.Aquickshotoflocalanesthetic,irrigate the wound, ninestitches, and I was done. I’dbe taking antibiotics for acouple of weeks, but otherthanthatI’dbefine.
Iknewitwashopeless,butI tried firing up thecommunications array. Nosignal,ofcourse.Theprimarysatellite dish had broken off,remember? And it took thereception antennae with it.The Hab had secondary andtertiary communicationssystems, but they were bothjust for talking to theMAV,which would use its muchmore powerful systems to
relay to Hermes. Thing is,thatonlyworksiftheMAVisstillaround.I had no way to talk to
Hermes. In time, I couldlocate the dish out on thesurface, but it would takeweeks for me to rig up anyrepairs,andthatwouldbetoolate. In an abort, Hermeswould leave orbit withintwenty-four hours. Theorbital dynamics made the
trip safer and shorter theearlieryouleft,sowhywait?Checking out my suit, I
saw the antenna had plowedthrough my bio-monitorcomputer.WhenonanEVA,all the crew’s suits arenetworkedsowecanseeeachother’sstatus.Therestof thecrew would have seen thepressure in my suit drop tonearly zero, followedimmediately bymybio-signs
going flat. Add to thatwatching me tumble down ahill with a spear throughmein the middle of asandstorm…yeah. Theythought I was dead. Howcouldtheynot?Theymayhaveevenhada
brief discussion aboutrecovering my body, butregulations are clear. In theevent a crewman dies onMars, he stays on Mars.
Leaving his body behindreducesweight for theMAVon the trip back. Thatmeansmore disposable fuel and alargermarginoferror for thereturn thrust. No point ingiving that up forsentimentality.
So that’s the situation. I’mstranded onMars. I have noway to communicate withHermes or Earth. Everyone
thinksI’mdead.I’minaHabdesigned to last thirty-onedays.If the oxygenator breaks
down, I’ll suffocate. If thewaterreclaimerbreaksdown,I’ll die of thirst. If the Habbreaches, I’ll just kind ofexplode. If none of thosethingshappen, I’ll eventuallyrunoutof foodand starve todeath.Soyeah.I’mfucked.
CHAPTER2
LOGENTRY:SOL7
Okay,I’vehadagoodnight’ssleep, and things don’t seemas hopeless as they didyesterday.Today I took stock of
suppliesanddidaquickEVAto check up on the external
equipment. Here’s mysituation:The surface mission was
supposed to be thirty-onedays. For redundancy, thesupply probes had enoughfood to last the whole crewfifty-six days. That way ifone or two probes hadproblems, we’d still haveenough food to complete themission.Wewere sixdays inwhen
all hell broke loose, so thatleaves enough food to feedsixpeople for fiftydays. I’mjust one guy, so it’ll last methree hundred days. Andthat’s if I don’t ration it. SoI’vegotafairbitoftime.I’m pretty flush on EVA
suits,too.Eachcrewmemberhad two space suits: a flightspacesuit to wear duringdescent and ascent, and themuchbulkierandmorerobust
EVAsuittowearwhendoingsurface operations.My flightspacesuithasaholeinit,andof course the crew waswearing the other five whenthey returned toHermes.ButallsixEVAsuitsarestillhereandinperfectcondition.The Hab stood up to the
storm without any problems.Outside,thingsaren’tsorosy.I can’t find the satellite dish.It probably got blown
kilometersaway.The MAV is gone, of
course.Mycrewmatestookitup to Hermes. Though thebottom half (the landingstage) isstillhere.Noreasonto take that back up whenweight is the enemy. Itincludesthelandinggear, thefuel plant, and anything elseNASA figured it wouldn’tneed for the trip back up toorbit.
TheMDVisonitssideandthere’s a breach in the hull.Looks like the storm rippedthe cowling off the reservechute (which we didn’t haveto use on landing). Once thechutewasexposed,itdraggedtheMDV all over the place,smashing it against everyrock in thearea.Not that theMDVwould bemuch use tome. Its thrusters can’t evenlift its own weight. But it
mighthavebeenvaluable forparts.Mightstillbe.Bothroversarehalf-buried
in sand, but they’re in goodshape otherwise. Theirpressure seals are intact.Makes sense. Operatingprocedure when a storm hitsistostopmotionandwaitforthe storm to pass. They’remade to stand up topunishment.I’llbeabletodigthemoutwith adayor soof
work.I’ve lost communication
with the weather stations,placedakilometerawayfromthe Hab in four directions.They might be in perfectworkingorderforallIknow.The Hab’s communicationsare so weak right now itprobably can’t even reach akilometer.The solar cell array was
covered in sand, rendering it
useless (hint:solarcellsneedsunlight to make electricity).ButonceIsweptthecellsoff,they returned to fullefficiency.WhateverIendupdoing, I’ll have plenty ofpower for it. Two hundredsquare meters of solar cells,with hydrogen fuel cells tostore plenty of reserve. All Ineed todo issweep themoffeveryfewdays.Things indoors are great,
thanks to the Hab’s sturdydesign.I ran a full diagnostic on
the oxygenator. Twice. It’sperfect. If anything goeswrongwithit,there’sashort-termspare Icanuse.But it’ssolely for emergency usewhilerepairingthemainone.The spare doesn’t actuallypull CO2 apart and recapturetheoxygen.Itjustabsorbsthe
CO2 the sameway the spacesuits do. It’s intended to lastfive days before it saturatesthefilters,whichmeansthirtydays forme (just one personbreathing, instead of six). Sothere’ssomeinsurancethere.The water reclaimer is
working fine, too. The badnews is there’snobackup. Ifit stops working, I’ll bedrinkingreservewaterwhileIrigupaprimitivedistilleryto
boilpiss.Also,I’lllosehalfaliter of water per day tobreathing until the humidityin the Hab reaches itsmaximum and water startscondensing on every surface.ThenI’llbelickingthewalls.Yay. Anyway, for now, noproblems with the waterreclaimer.So yeah. Food, water,
shelter all taken care of. I’mgoing to start rationing food
right now. Meals are prettyminimalalready,butIthinkIcaneatathree-fourthsportionpermealandstillbeallright.That should turn my threehundred days of food intofour hundred. Foragingaround the medical area, Ifound the main bottle ofvitamins. There’s enoughmultivitamins there to lastyears. So I won’t have anynutritional problems (though
I’ll still starve todeathwhenI’m out of food, no matterhowmanyvitaminsItake).The medical area has
morphine for emergencies.And there’s enough there foralethaldose.I’mnotgoingtoslowlystarvetodeath,I’lltellyouthat.IfIgettothatpoint,I’lltakeaneasierwayout.Everyone on the mission
had two specialties. I’m abotanist and mechanical
engineer; basically, themission’s fix-it man whoplayed with plants. Themechanical engineeringmight save my life ifsomethingbreaks.I’ve been thinking about
how to survive this. It’s notcompletelyhopeless.There’llbe humans back on Mars inaboutfouryearswhenAres4arrives (assuming they didn’tcancel the program in the
wakeofmy“death”).Ares 4 will be landing at
theSchiaparelli crater,whichis about 3200 kilometersaway from my location herein Acidalia Planitia. No wayfor me to get there on myown. But if I couldcommunicate,Imightbeabletogetarescue.Notsurehowthey’d manage that with theresourcesonhand,butNASAhasalotofsmartpeople.
So that’smymissionnow.Find a way to communicatewithEarth. If I can’tmanagethat, find a way tocommunicate with Hermeswhen it returns in four yearswiththeAres4crew.Ofcourse,Idon’thaveany
plan for surviving four yearsononeyearof food.Butonethingatatimehere.Fornow,I’m well fed and have apurpose:Fixthedamnradio.

Ispentmostoftodayoutatwhat’s left of thecommunications array. It’sreally a sorry sight. Imayaswellyell towardEarthforallthe good that damned thingwilldome.I could throw together a
rudimentarydishoutofmetalI find around the base, butthis isn’t some walkie-talkieI’m working with here.CommunicatingfromMarsto
Earthisaprettybigdeal,andrequires extremelyspecialized equipment. Iwon’t be able to whipsomethingupwithtinfoilandgum.I need to rationmy EVAs
as well as food. The CO2filtersarenotcleanable.Oncethey’re saturated, they’redone.Themission accountedforafour-hourEVApercrewmemberperday.Fortunately,
CO2 filters are light andsmall, so NASA had theluxury of sending more thanwe needed. All told, I haveabout 1500 hours’ worth ofCO2 filters. After that, anyEVAs I do will have to bemanaged with bloodlettingtheair.Fifteenhundredhoursmay
soundlikealot,butI’mfacedwith spending at least four
years here if I’m going tohaveanyhopeofrescue,witha minimum of several hoursper week dedicated tosweeping off the solar array.Anyway.NoneedlessEVAs.
Inothernews,I’mstartingtocome up with an idea forfood.Mybotany backgroundmaycomeinusefulafterall.Why bring a botanist to
Mars? After all, it’s famous
for not having anythinggrowing there.Well, the ideawas to figure out how wellthings grow in Martiangravity, and see what, ifanything, we can do withMartian soil. The shortanswer is: quite a lot…almost. Martian soil has thebasic building blocks neededforplantgrowth,butthere’salotof stuffgoingon inEarthsoil that Mars soil doesn’t
have, even when it’s placedin an Earth atmosphere andgiven plenty of water.Bacterial activity, certainnutrients provided by animallife, etc. None of that ishappening on Mars. One ofmytasks for themissionwasto see howplants growhere,in various combinations ofEarth and Mars soil andatmosphere.That’swhy I have a small
amount of Earth soil and abunchofplantseedswithme.I can’t get too excited,
however. It’s about theamountofsoilyou’dputinawindow box, and the onlyseedsIhaveareafewspeciesof grass and ferns. They’rethe most rugged and easilygrown plants on Earth, soNASApickedthemasthetestsubjects.So I have two problems:
not enough dirt, and nothingedibletoplantinit.ButI’mabotanist,damnit.
Ishouldbeabletofindawayto make this happen. If Idon’t, I’ll be a really hungrybotanistinaboutayear.
LOGENTRY:SOL11
I wonder how the Cubs aredoing.
LOGENTRY:SOL14
Igotmyundergraddegreeatthe University of Chicago.Half the people who studiedbotany were hippies whothought they could return tosome natural world system.Somehow feeding sevenbillion people through puregathering.Theyspentmostoftheir timeworking out betterways to grow pot. I didn’tlikethem.I’vealwaysbeenin
it for thescience,notforanyNewWorldOrderbullshit.When they made compost
heaps and tried to conserveevery little ounce of livingmatter, I laughed at them.“Look at the silly hippies!Look at their patheticattempts to simulate acomplex global ecosystem intheirbackyard.”Of course, now I’m doing
exactlythat.I’msavingevery
scrapofbiomatterIcanfind.Every time I finish a meal,the leftovers go to thecompostbucket.As forotherbiologicalmaterial…The Hab has sophisticated
toilets. Shit is usuallyvaccum-dried, thenaccumulatedinsealedbagstobediscardedonthesurface.Notanymore!Infact,IevendidanEVA
to recover the previous bagsof shit from before the crewleft. Being completelydesiccated,thisparticularshitdidn’t have bacteria in itanymore, but it still hadcomplex proteins and wouldserve as useful manure.Addingit towaterandactivebacteria would quickly get itinundated, replacing anypopulation killed by theToiletofDoom.
Ifoundabigcontainerandput a bit of water in it, thenadded the dried shit. Sincethen,I’veaddedmyownshitto it as well. The worse itsmells, the better things aregoing. That’s the bacteria atwork!Once I get some Martian
soil inhere, I canmix in theshitandspread itout.ThenIcansprinkletheEarthsoilontop.Youmightnotthinkthat
would be an important step,but it is.Therearedozensofspecies of bacteria living inEarthsoil,andthey’recriticalto plant growth. They’llspread out and breed like…well, like a bacterialinfection.People have been using
humanwaste as fertilizer forcenturies. It’s even got apleasant name: “night soil.”Normally, it’s not an ideal
waytogrowcrops,becauseitspreads disease: Humanwastehaspathogensinitthat,you guessed it, infecthumans. But it’s not aproblem for me. The onlypathogens in this waste aretheonesIalreadyhave.Withinaweek,theMartian
soilwillbereadyforplantstogerminate in. But I won’tplant yet. I’ll bring in morelifeless soil fromoutside and
spread some of the live soilover it. It’ll “infect” the newsoilandI’llhavedoublewhatI started with. After anotherweek, I’ll double it again.Andsoon.Ofcourse,all thewhile, I’ll be adding all newmanuretotheeffort.My asshole is doing as
muchtokeepmealiveasmybrain.This isn’t a new concept I
just came up with. People
have speculated on how tomakecropsoiloutofMartiandirt for decades. I’ll just beputting it to the test for thefirsttime.Isearchedthroughthefood
suppliesandfoundallsortsofthings that I can plant. Peas,for instance.Plentyofbeans,too. I also found severalpotatoes. If any of them canstill germinate after theirordeal,that’llbegreat.Witha
nearly infinite supply ofvitamins, all I need arecalories of any kind tosurvive.Thetotalfloorspaceofthe
Hab is about 92 squaremeters. I plan to dedicate allof it to thisendeavor. Idon’tmindwalkingondirt. It’llbea lot of work, but I’m goingto need to cover the entirefloor to a depth of 10centimeters. That means I’ll
have to transport 9.2 cubicmeters of Martian soil intotheHab.Icangetmaybeone-tenth of a cubic meter inthrough theairlockata time,and it’ll be backbreakingwork to collect it. But in theend, if everything goes toplan, I’ll have 92 squaremetersofcrop-ablesoil.Hell yeah I’m a botanist!
Fearmybotanypowers!
LOGENTRY:SOL15
Ugh! This is backbreakingwork!I spent twelve hours today
onEVAstobringdirtintotheHab.Ionlymanagedtocovera small corner of the base,maybefivesquaremeters.Atthisrateit’lltakemeweekstoget all the soil in. But hey,timeisonethingI’vegot.The first few EVAs were
pretty inefficient; me fillingsmallcontainersandbringingthem in through the airlock.Then I gotwise and just putone big container in theairlock itself and filled thatwith small containers till itwas full.That sped thingsupalotbecausetheairlocktakesabout ten minutes to getthrough.I ache all over. And the
shovels I have are made for
taking samples, not heavydigging. My back is killingme. I foraged in themedicalsupplies and found someVicodin. I took it about tenminutes ago. Should bekickinginsoon.Anyway, it’s nice to see
progress.Timetostartgettingthebacteria toworkon theseminerals. After lunch. Nothree-fourths ration today.I’veearnedafullmeal.
LOGENTRY:SOL16
One complication I hadn’tthoughtof:water.Turns out being on the
surface of Mars for a fewmillion years eliminates allthe water in the soil. Mymaster’s degree in botanymakes me pretty sure plantsneedwetdirt togrowin.Notto mention the bacteria thathastoliveinthedirtfirst.
Fortunately, I have water.ButnotasmuchasIwant.Tobeviable,soilneeds40litersofwaterpercubicmeter.Myoverall plan calls for 9.2cubic meters of soil. So I’lleventually need 368 liters ofwatertofeedit.The Hab has an excellent
water reclaimer. Besttechnology available onEarth. So NASA figured,“Why send a lot ofwater up
there? Just send enough foranemergency.”Humansneedthreelitersofwaterperdaytobecomfortable.Theygaveus50 liters each, making 300literstotalintheHab.I’m willing to dedicate all
butanemergency50liters tothe cause. That means I canfeed 62.5 square meters at adepth of 10 centimeters.Abouttwo-thirdsoftheHab’sfloor. It’ll have to do.That’s
thelong-termplan.Fortoday,my goal was five squaremeters.I wadded up blankets and
uniforms from my departedcrewmates to serve as oneedgeofaplanterboxwiththecurvedwallsoftheHabbeingthe rest of the perimeter. Itwas as close to five squaremeters as I could manage. Ifilled itwith sand to a depthof 10 centimeters. Then I
sacrificed 20 liters ofprecious water to the dirtgods.Thenthingsgotdisgusting.
Idumpedmybigcontainero’shit onto the soil and nearlypuked from the smell. Imixed this soil and shittogether with a shovel, andspread it out evenly again.Then I sprinkled the Earthsoil on top. Get to work,bacteria. I’m counting on
you. That smell’s going tostickaround forawhile, too.It’s not like I can open awindow.Still,yougetusedtoit.In other news, today is
Thanksgiving.Myfamilywillbe gathering in Chicago fortheusualfeastatmyparents’house. My guess is it won’tbe much fun, what with mehaving died ten days ago.Hell, they probably just got
donewithmyfuneral.I wonder if they’ll ever
find out what reallyhappened. I’ve been so busystaying alive I never thoughtofwhat thismust be like formy parents. Right now,they’re suffering the worstpain anyone can endure. I’dgiveanythingjusttoletthemknowI’mstillalive.I’ll just have to survive to
makeupforit.
LOGENTRY:SOL22
Wow. Things really camealong.I got all the sand in and
readytogo.Two-thirdsofthebaseisnowdirt.AndtodayIexecuted my first dirt-doubling. It’s been a week,andtheformerMartiansoilisrich and lovely. Two moredoublings and I’ll havecoveredthewholefield.
Allthatworkwasgreatformy morale. It gave mesomething to do. But afterthingssettleddownabit,andIhaddinnerwhilelisteningtoJohanssen’s Beatles musiccollection, I got depressedagain.Doingthemath, thiswon’t
keepmefromstarving.My best bet for making
calories is potatoes. Theygrow prolifically and have a
reasonable caloric content(770 calories per kilogram).I’m pretty sure the ones Ihavewillgerminate.Problemis I can’t grow enough ofthem. In 62 square meters, Icould grow maybe 150kilograms of potatoes in 400days (the time I have beforerunningoutoffood).That’sagrand total of 115,500calories, a sustainableaverage of 288 calories per
day. With my height andweight, if I’m willing tostarve a little, I need 1500caloriesperday.Notevenclose.So I can’t just live off the
landforever.ButIcanextendmylife.Thepotatoeswilllastme76days.Potatoes grow continually,
so in those 76 days, I cangrow another 22,000 calories
of potatoes, which will tidemeover for another15days.After that, it’s kind ofpointless to continue thetrend. All told it buys meabout90days.SonowI’llstartstarvingto
death on Sol 490 instead ofSol400.It’sprogress,butanyhope of survival rests onmesurviving until Sol 1412,whenAres4willland.There’s about a thousand
days of food I don’t have.And I don’t have a plan forhowtogetit.Shit.

AndIneedenoughtolastthe1387solsuntilAres4arrives.IfIdon’tgetrescuedbyAres4, I’mdeadanyway.Asol is39minuteslongerthanaday,so it works out to be 1425days. That’smy target: 1425daysoffood.
I have plenty ofmultivitamins; over doublewhatIneed.Andthere’sfivetimestheminimumproteinineach food pack, so carefulrationing of portions takescare ofmy protein needs forat least four years. Mygeneralnutritionistakencareof.Ijustneedcalories.I need 1500 calories every
day. Ihave400daysof foodto start off with. So how
many calories do I need togenerate per day along theentire time period to stayaliveforaround1425days?I’ll spare you the math.
The answer is about 1100. Ineed to create 1100 caloriesper day with my farmingeffortstosurviveuntilAres4gets here. Actually, a littlemore than that, because it’sSol 25 right now and Ihaven’t actually planted
anythingyet.Withmy 62 squaremeters
of farmland, I’ll be able tocreate about 288 calories perday. So I need almost fourtimes my current plan’sproductiontosurvive.That means I need more
surface area for farming, andmore water to hydrate thesoil. So let’s take theproblemsoneatatime.
Howmuch farmland can Ireallymake?Thereare92squaremeters
in theHab.Let’s say I couldmakeuseofallofit.Also, therearefiveunused
bunks.Let’s say Iput soil inon them, too. They’re 2square meters each, givingme 10 more square meters.Sowe’reupto102.The Hab has three lab
tables, each about 2 squaremeters.Iwanttokeeponeformyownuse, leaving two forthe cause. That’s another 4square meters, bringing thetotalto106.Ihave twoMartian rovers.
They have pressure seals,allowing the occupants todrive without space suitsduringlongperiodstraversingthe surface. They’re toocramped to plant crops in,
andIwanttobeabletodrivethem around anyway. Butboth rovers have anemergencypop-tent.Therearealotofproblems
with using pop-tents asfarmland, but they have 10square meters of floor spaceeach. Presuming I canovercome the problems, theynet me another 20 squaremeters,bringingmyfarmlandupto126.
One hundred and twenty-sixsquaremetersoffarmableland. That’s something towork with. I still don’t havethe water to moisten all thatsoil,butlikeIsaid,onethingatatime.The next thing to consider
is how efficient I can be ingrowingpotatoes.Ibasedmycrop yield estimates on thepotatoindustrybackonEarth.Butpotatofarmersaren’tina
desperate race for survivallike I am. Can I get a betteryield?For starters, I can give
attention to each individualplant. I can trim them andkeep them healthy and notinterfering with each other.Also, as their floweringbodies breach the surface, Icanreplantthemdeeper,thenplant younger plants abovethem. For normal potato
farmers, it’s notworth doingbecausethey’reworkingwithliterally millions of potatoplants.Also, this sort of farming
annihilates the soil. Anyfarmer doing it would turntheir land into a dust bowlwithin twelve years. It’s notsustainable.Butwhocares?Ijust need to survive for fouryears.I estimate I can get 50
percenthigheryieldbyusingthese tactics. And with the126 square meters offarmland (just over doublethe 62 square meters I nowhave) itworksout tobeover850caloriesperday.That’s real progress. I’d
still be in danger ofstarvation, but it gets me intherangeofsurvival.Imightbe able tomake it by nearlystarvingbutnotquitedying.I
could reduce my caloric usebyminimizingmanual labor.Icouldsetthetemperatureofthe Hab higher than normal,meaning my body wouldexpend less energy keepingits temperature. I could cutoffanarmandeatit,gainingme valuable calories andreducing my overall caloricneed.No,notreally.So let’s say I could clear
up that much farmland.Seems reasonable.Where doI get the water? To go from62 to 126 square meters offarmland at 10 centimetersdeep,I’llneed6.4morecubicmeters of soil (moreshoveling, whee!) and that’llneedover250litersofwater.The 50 liters I have is for
me to drink if the waterreclaimerbreaks.So I’m250liters short of my 250-liter
goal.Bleh.I’mgoingtobed.
LOGENTRY:SOL26
It was a backbreaking yetproductiveday.I was sick of thinking, so
insteadoftryingtofigureoutwhere I’ll get 250 liters ofwater, I did some manuallabor. I need to get a wholeassload more soil into the
Hab, even if it is dry anduselessrightnow.I got a cubic meter in

going to happen while wewere doing surfaceoperations, and NASA’sshrinks thought it would begood for us to make a mealtogether.Notjusttoeatit,buttoactuallyprepareit.There’sprobably some logic to that,butwhocares?I cut each potato into four
pieces, making sure eachpiece had at least two eyes.The eyes are where they
sproutfrom.Iletthemsitfora few hours to harden a bit,then planted them, wellspaced apart, in the corner.Godspeed, little taters. Mylifedependsonyou.Normally, it takes at least
90 days to yield full-sizedpotatoes.ButIcan’twaitthatlong. I’ll need to cut up allthepotatoesfromthiscroptoseedtherestofthefield.By setting the Hab

Over the last fewdays, I gotinall thedirt that I’llneed. Iprepped the tablesandbunksforholdingtheweightofsoil,andevenputthedirtinplace.There’sstillnowatertomakeit viable, but I have someideas. Really bad ideas, butthey’reideas.Today’s big
accomplishment was settingupthepop-tents.
The problem with therovers’ pop-tents is theyweren’tdesignedforfrequentuse.The idea was you’d throw
out a pop-tent, get in, andwaitforrescue.Theairlockisnothingmorethanvalvesandtwo doors. Equalize theairlock with your side of it,getin,equalizewiththeotherside,getout.Thismeansyoulosealotofairwitheachuse.
AndI’llneedtogetinthereatleast once a day. The totalvolume of each pop-tent isprettylow,soIcan’taffordtoloseairfromit.I spent hours trying to
figure out how to attach apop-tent airlock to a Habairlock. I have three airlocksin theHab. I’d bewilling todedicate two to pop-tents.That would have beenawesome.
Thefrustratingpartispop-tent airlocks can attach toother airlocks! You mighthave injured people in there,or not enough space suits.You need to be able to getpeople out without exposingthem to the Martianatmosphere.But the pop-tents were
designed for your crewmatestocomerescueyouinarover.The airlocks on the Hab are
much larger and completelydifferentfromtheairlocksonthe rovers. When you thinkabout it, there’s really noreason toattachapop-tent totheHab.Unless you’re stranded on
Mars,everyone thinksyou’redead, and you’re in adesperate fight against timeandtheelementstostayalive.But, you know, other thanthat edge case, there’s no
reason.SoIfinallydecidedI’djust
take the hit. I’ll be losingsomeaireverytimeIenterorexit a pop-tent. The goodnews is each pop-tent has anair feedvalveon theoutside.Remember, these areemergency shelters. Theoccupantsmightneedair,andyou can provide it from arover by hooking up an airline.It’snothingmorethana
tubethatequalizestherover’sairwiththepop-tent’s.TheHabandtheroversuse
the same valve and tubingstandards, so I was able toattach the pop-tents directlyto the Hab. That’llautomatically replenish theairIlosewithmyentriesandexits (what we NASA folkcallingressandegress).NASA was not screwing
aroundwith theseemergency
tents. The moment I pushedthepanicbutton in the rover,there was an ear-poppingwhoosh as the pop-tent firedout, attached to the roverairlock. It took about twoseconds.I closed the airlock from
the rover side and ended upwithanice,isolatedpop-tent.Setting up the equalizer hosewas trivial (for once I’musing equipment the way it
was designed to be used).Then, after a few tripsthrough the airlock (with theair-loss automaticallyequalized by the Hab) I gotthedirtin.I repeated the process for
the other tent. Everythingwentreallyeasily.Sigh…water.In high school, I played a

here onMars. There’s ice atthe poles, but they’re too faraway. If I want water, I’ll
havetomakeitfromscratch.Fortunately, I know therecipe: Take hydrogen. Addoxygen.Burn.Let’s take them one at a
time.I’llstartwithoxygen.I have a fair bit of O2
reserves, but not enough tomake250litersofwater.Twohigh-pressure tanks at oneendof theHabaremyentiresupply (plus the air in the
Hab of course). They eachcontain25litersofliquidO2.TheHabwouldusethemonlyin an emergency; it has theoxygenator to balance theatmosphere. The reason theO2 tanks are here is to feedthespacesuitsandrovers.Anyway, the reserve
oxygen would only beenough tomake100 litersofwater (50 liters of O2makes
100 liters of molecules thatonly have oneO each). ThatwouldmeannoEVAsforme,and no emergency reserves.And itwouldmake less thanhalf thewater I need.Out ofthequestion.Butoxygen’seasiertofind
on Mars than you mightthink. The atmosphere is 95percentCO2.AndIhappentohave a machine whose solepurpose is liberating oxygen
fromCO2.Yay,oxygenator!One problem: The
atmosphereisverythin—lessthan1percentofthepressureon Earth. So it’s hard tocollect. Getting air fromoutside to inside is nearlyimpossible. The wholepurposeoftheHabistokeepthat sort of thing fromhappening. The tiny amountof Martian atmosphere thatenters when I use an airlock
islaughable.That’s where the MAV
fuelplantcomesin.My crewmates took away
theMAVweeksago.Butthebottom half of it stayedbehind. NASA isn’t in thehabit of putting unnecessarymass into orbit. The landinggear, ingress ramp, and fuelplantarestillhere.Rememberhow theMAVmade its ownfuel with help from the
Martian atmosphere? Stepone of that is to collect CO2andstoreitinahigh-pressurevessel. Once I get the fuelplanthookedup to theHab’spower, it’ll give me half aliter of liquid CO2 per hour,indefinitely. After ten solsit’ll have made 125 liters ofCO2, which will make 125liters of O2 after I feed itthroughtheoxygenator.
That’senoughtomake250liters of water. So I have aplanforoxygen.The hydrogen will be a
littletrickier.I considered raiding the
hydrogen fuel cells, but Ineed those batteries tomaintain power at night. If Idon’t have that, it’ll get toocold. I could bundle up, butthecoldwouldkillmycrops.Andeachfuelcellhasonlya
small amount ofH2 anyway.It’s justnotworth sacrificingso much usefulness for solittle gain. The one thing Ihave going for me is thatenergy is not a problem. Idon’twanttogivethatup.So I’ll have to go a
differentroute.I often talk about the
MAV.ButnowIwanttotalkabouttheMDV.
During the most terrifyingtwenty-three minutes of mylife, four of my crewmatesand I tried not to shitourselves while MartinezpilotedtheMDVdowntothesurface. It was kind of likebeinginatumble-dryer.First, we descended from
Hermes, and decelerated ourorbital velocity so we couldstart falling properly.Everything was smooth until
wehittheatmosphere.Ifyouthinkturbulenceisroughinajetliner going 720 kph, justimagine what it’s like at28,000kph.Several staged sets of
chutes deployedautomatically to slow ourdescent, then Martinezmanually piloted us to theground,using the thrusters toslow descent and control ourlateral motion. He’d trained
for this for years, and he didhis job extraordinarily well.He exceeded all plausibleexpectations of landings,putting us just nine metersfrom the target.The guy justplainownedthatlanding.Thanks, Martinez! You
mayhavesavedmylife!Not because of the perfect
landing, but because he leftso much fuel behind.Hundreds of liters of unused
hydrazine. Each molecule ofhydrazine has four hydrogenatoms in it. So each liter ofhydrazine has enoughhydrogen for two liters ofwater.Idida littleEVAtoday to
check. The MDV has 292litersofjuiceleftinthetanks.Enough to make almost 600liters of water! Way morethanIneed!There’s just one catch:
Liberating hydrogen fromhydrazine is…well…it’s howrockets work. It’s really,really hot.And dangerous. IfI do it in an oxygenatmosphere, the hot andnewlyliberatedhydrogenwillexplode. There’ll be a lot ofH2Oattheend,butI’llbetoodeadtoappreciateit.At its root, hydrazine is
pretty simple. The Germansused it as far back asWorld
War II for rocket-assistedfighter fuel (andoccasionallyblewthemselvesupwithit).Allyouhavetodoisrunit
over a catalyst (which I canextract from the MDVengine) and it will turn intonitrogen and hydrogen. I’llspare you the chemistry, butthe end result is that fivemolecules of hydrazinebecomes five molecules ofharmless N2 and ten
molecules of lovely H2.During this process, it goesthrough an intermediate stepof being ammonia.Chemistry, being the sloppybitch it is, ensures there’llbesome ammonia that doesn’treact with the hydrazine, soit’ll just stay ammonia. Youlike the smell of ammonia?Well, it’llbeprevalent inmyincreasinglyhellishexistence.The chemistry is on my
side. The question now ishow do I actually make thisreaction happen slowly, andhow do I collect thehydrogen? The answer is: Idon’tknow.I suppose I’ll think of
something.Ordie.Anyway, much more
important: I simply can’tabide the replacement ofChrissy with Cindy. Three’sCompany may never be the
same after this fiasco. Timewilltell.
CHAPTER4
LOGENTRY:SOL32
So I ran into a bunch ofproblemswithmywaterplan.My idea is to make 600
litersofwater(limitedbythehydrogen I can get from thehydrazine). That means I’llneed300litersofliquidO2.
I can create the O2 easilyenough.IttakestwentyhoursfortheMAVfuelplanttofillits 10-liter tank with CO2.The oxygenator can turn itintoO2, then theatmosphericregulator will see the O2content in the Hab is high,and pull it out of the air,storing it in the main O2tanks. They’ll fill up, so I’llhavetotransferO2overtothe
rovers’ tanks and even thespacesuittanksasnecessary.But I can’t create it very
quickly.AthalfaliterofCO2per hour, itwill take twenty-fivedaystomaketheoxygenIneed.That’slongerthanI’dlike.Also, there’s the problem
of storing the hydrogen. Theair tanks of the Hab, therovers,andallthespacesuits
adduptoexactly374litersofstorage. To hold all thematerials for water, I wouldneedawhopping900litersofstorage.I considered using one of
the rovers as a “tank.” Itwould certainly be bigenough, but it just isn’tdesignedtoholdinthatmuchpressure. It’s made to hold(you guessed it) oneatmosphere. I need vessels
that can hold fifty times thatmuch.I’msurearoverwouldburst.The best way to store the
ingredients of water is tomake them be water. Sowhat’swhatI’llhavetodo.
Theconceptissimple,buttheexecution will be incrediblydangerous.Every twenty hours, I’ll
have 10 liters of CO2 thanks
to the MAV fuel plant. I’llvent it into the Hab via thehighly scientific method ofdetaching the tank from theMAVlandingstruts,bringingit into theHab, then openingthevalveuntilit’sempty.Theoxygenatorwillturnit
intooxygeninitsowntime.Then, I’ll release
hydrazine, very slowly, overtheiridiumcatalyst,toturnit
intoN2andH2.I’lldirectthehydrogen toa smallareaandburnit.As you can see, this plan
provides many opportunitiesfor me to die in a fieryexplosion.Firstly, hydrazine is some
serious death. If I make anymistakes, there’ll be nothingleft but the “Mark WatneyMemorial Crater” where the
Haboncestood.Presuming I don’t fuck up
with the hydrazine, there’sstill the matter of burninghydrogen. I’m going to besettinga fire. In theHab.Onpurpose.If you asked every
engineer at NASA what theworst scenario for the Habwas, they’dallanswer“fire.”If you asked them what theresult would be, they’d
answer“deathbyfire.”But if I canpull itoff, I’ll
be making watercontinuously,withnoneedtostore hydrogen or oxygen.It’ll be mixed into theatmosphere as humidity, butthe water reclaimer will pullitout.I don’t even have to
perfectlymatchthehydrazineend of it with the fuel plant
CO2 part. There’s plenty ofoxygenintheHab,andplentymoreinreserve.Ijustneedtomake sure not to make somuchwater I runmyself outofO2.IhookeduptheMAVfuel

Thismaybemylastentry.
I’ve known since Sol 6there was a good chance I’ddie here. But I figured itwould be when I ran out offood. I didn’t think it wouldbethisearly.I’m about to fire up the
hydrazine.Our mission was designed
knowing that anythingmightneed maintenance, so I haveplenty of tools. Even in aspace suit, I was able to pry
the access panels off theMDV and get at the sixhydrazinetanks.Isetthemintheshadowofarovertokeepthem from heating up toomuch. There’s more shadeandacoolertemperaturenearthe Hab, but fuck that. Ifthey’re going to blow up,theycanblowuparover,notmyhouse.Then I pried out the

chamber in. I brieflyconsidered only bringing onetankofhydrazineinatatimeto reduce risk. But someback-of-the-napkin math told
meevenonetankwasenoughtoblowthewholeHabup.SoI brought them all in. Whynot?The tanks have manual
vent valves. I’m not 100percentsurewhatthey’refor.Certainly we were neverexpected touse them. I thinkthey’re there to releasepressure during the manyquality checks done duringconstruction and before
fueling.Whatever thereason,I have valves to work with.Allittakesisawrench.I liberated a spare water
hose from the waterreclaimer. With some threadtorn out of a uniform (sorry,Johanssen), I attached it tothevalveoutput.Hydrazineisaliquid,soallIhavetodoislead it to the reactionchamber(moreofa“reactionbowl”now).
Meanwhile, theMAV fuelplant is still working. I’vealreadybroughtinonetankofCO2,ventedit,andreturneditforrefilling.So there are no more

I’mwritingthislogtoyou,dear future Marsarchaeologist, from Rover 2.You may wonder why I’mnot in the Hab right now.BecauseIfledinterror,that’swhy!And I’m not surewhatthehelltodonext.I guess I should explain
what happened. If this ismylast entry, you’ll at leastknowwhy.Over the past few days,
I’ve been happily makingwater. It’s been goingswimmingly. (Seewhat I didthere?“Swimmingly”?)IevenbeefeduptheMAV
fuel plant compressor. Itwasverytechnical(Iincreasedthevoltage to thepump).So I’mmaking water even fasternow.Aftermyinitialburstof50

I made 50 liters of water,that’sanassumption. Ididn’treclaim 50 liters of water.The additional soil I’d filledthe Hab with was extremely
dryandgreedily suckedupalot of the humidity. That’swhere Iwant thewater togoanyway, so I’m not worried,and I wasn’t surprised whenthe reclaimer didn’t getanywherenear50liters.Iget10litersofCO2every
fifteen hours now that Isouped up the pump. I’vedone this process four times.My math tells me that,including my initial 50-liter
burst, I should have added130 liters of water to thesystem.Wellmymathwasadamn
liar!I’d gained 70 liters in the
water reclaimer and thespace-suit-turned-water-tank.There’s plenty ofcondensationonthewallsanddomed roof, and the soil iscertainly absorbing its fairshare. But that doesn’t
account for 60 liters ofmissing water. Somethingwaswrong.That’s when I noticed the
otherO2tank.The Hab has two reserve
O2tanks.Oneoneachsideofthe structure, for safetyreasons. TheHab can decidewhichonetousewheneveritwants. Turns out it’s beentopping off the atmosphere
fromTank1.ButwhenIaddO2 to the system (via theoxygenator), the Hab evenlydistributes the gain betweenthe two tanks. Tank 2 hasbeenslowlygainingoxygen.That’s not a problem. The
Hab is justdoing its job.Butit does mean I’ve beengainingO2 over time.Whichmeans I’m not consuming itasfastasIthought.
At first, I thought “Yay!More oxygen! Now I canmakewater faster!”But thena more disturbing thoughtoccurredtome.Follow my logic: I’m
gaining O2. But the amountI’m bringing in from outsideis constant. So the only wayto“gain”itistobeusinglessthan I thought.But I’vebeendoing the hydrazine reactionwith the assumption that I
wasusingallofit.The only possible
explanation is that I haven’tbeen burning all the releasedhydrogen.It’s obvious now, in
retrospect. But it neveroccurred to me that some ofthe hydrogen just wouldn’tburn. It got past the flame,and went on its merry way.Damn it, Jim, I’mabotanist,notachemist!
Chemistry is messy, sothere’sunburnedhydrogen intheair.Allaroundme.Mixedin with the oxygen. Just…hanging out. Waiting for aspark so it canblow theHabup!OnceIfiguredthisoutand
composed myself, I got aZiploc-sized sample bag andwaved it around a bit, thensealedit.Then, a quick EVA to a
rover, where we keep theatmospheric analyzers.Nitrogen: 22 percent.Oxygen: 9 percent.Hydrogen:64percent.I’vebeenhidinghereinthe
rovereversince.It’s Hydrogenville in the
Hab.I’m very lucky it hasn’t
blown. Even a small staticdischarge would have led to
myownprivateHindenburg.So, I’mhere inRover 2. I
can stay for a day or two,tops, before the CO2 filtersfrom the rover andmy spacesuitfillup.Ihavethatlongtofigure out how to deal withthis.TheHabisnowabomb.

I’m still cowering in therover, but I’ve had time tothink. And I know how todealwiththehydrogen.I thought about the
atmosphericregulator.Itpaysattention to what’s in the air
and balances it. That’s howthe excess O2 I’ve beenimporting ends up in thetanks.Problemis,it’sjustnotbuilt to pull hydrogen out oftheair.The regulator uses freeze-
separation to sort out thegasses. When it decidesthere’s too much oxygen, itstarts collecting air in a tankand cooling it to 90 kelvin.That makes the oxygen turn
to liquid, but leaves thenitrogen (condensation point:77K) still gaseous. Then itstorestheO2.ButIcan’tgetittodothat
for hydrogen, becausehydrogen needs to be below21K to turn liquid. And theregulator just can’t gettemperatures that low. Deadend.Here’sthesolution:
Hydrogen is dangerousbecauseitcanblowup.Butitcan only blow up if there’soxygen around. Hydrogenwithout oxygen is harmless.Andtheregulatorisallaboutpullingoxygenoutoftheair.There are four different
safety interlocks that preventthe regulator from letting theHab’soxygencontentgettoolow. But they’re designed toworkagainst technical faults,
not deliberate sabotage (bwahaha!).Long story short, I can
tricktheregulatorintopullingalltheoxygenoutoftheHab.Then I canwear a space suit(so I can breathe) and dowhatever Iwantwithout fearofblowingup.I’lluseanO2tanktospray
short bursts of oxygen at thehydrogen, and make a spark
with a couple ofwires and abattery. It’ll set thehydrogenon fire, but only until thesmall bit of oxygen is usedup.I’ll just do that over and
over, in controlled bursts,until I’ve burned off all thehydrogen.One tiny flaw with that
plan:It’llkillmydirt.Thedirt isonlyviable soil
because of the bacteriagrowinginit.IfIgetridofallthe oxygen, the bacteria willdie. I don’t have 100 billionlittlespacesuitshandy.It’shalfasolutionanyway.Time to take a break from
thinking.CommanderLewiswasthe

IthinkI’vegotit.Soil bacteria are used to
winters.Theyget lessactive,and require less oxygen tosurvive. I can lower theHabtemperature to 1°C, andthey’ll nearly hibernate. ThissortofthinghappensonEarthallthetime.Theycansurvive
a couple of days thisway. Ifyou’re wondering howbacteria on Earth survivelonger periods of cold, theansweristheydon’t.Bacteriafrom further undergroundwhere it is warmer breedupward to replace the deadones.They’ll still need some
oxygen,butnotmuch.Ithinka 1 percent content will dothe trick. That leaves a little
in the air for the bacteria tobreathe, but not enough tomaintain a fire. So thehydrogenwon’tblowup.But that leads to yet
another problem. The potatoplantswon’tliketheplan.They don’t mind the lack
of oxygen, but the cold willkill them.So I’ll have to potthem(bagthem,actually)andmove them to a rover. Theyhaven’tevensproutedyet, so
it’snotliketheyneedlight.It was surprisingly
annoying to find a way tomake the heat stay on whentherover’sunoccupied.But Ifigured it out. After all, I’vegotnothingbuttimeinhere.
So that’s the plan. First, bagthe potato plants and bringthem to the rover (makesureitkeeps thedamnheateron).Then drop the Hab
temperature to 1°C. Thenreduce the O2 content to 1percent. Then burn off thehydrogen with a battery,somewires,andatankofO2.Yeah. This all sounds like
agreatideawithnochanceofcatastrophicfailure.That was sarcasm, by the
way.Well,offIgo.
LOGENTRY:SOL40
Things weren’t 100 percentsuccessful.They say no plan survives
first contact withimplementation. I’d have toagree.Here’swhathappened:I summoned up the
courage to return to theHab.OnceIgotthere,Ifeltalittlemore confident. EverythingwashowI’dleftit.(Whatdid
Iexpect?Martianslootingmystuff?)Itwouldtakeawhiletolet
theHabcool,soIstartedthatright away by turning thetemperaturedownto1°C.I bagged thepotatoplants,
andgotachancetocheckupon them while I was at it.They’re rooting nicely andabout to sprout. One thing Ihadn’taccountedforwashowtobringthemfromtheHabto
therovers.The answer was pretty
easy. I put all of them inMartinez’s space suit.Then Idraggeditoutwithmetotherover I’d set up as atemporarynursery.Making sure to jimmy the
heater to stay on, I headedbacktotheHab.By the time I got back, it
was already chilly. Down to
5°C already. Shivering andwatchingmybreathcondensein front of me, I threw onextra layers of clothes.FortunatelyI’mnotaverybigman. Martinez’s clothes fitover mine, and Vogel’s fitoverMartinez’s.These shittyclothes were designed to beworn in a temperature-controlledenvironment.Evenwith three layers, I was stillcold.Iclimbedintomybunk
andunderthecoversformorewarmth.Once the temperature got
to1°C,Iwaitedanotherhour,justtomakesurethebacteriain thedirt got thememo thatitwastimetotakeitslow.ThenextproblemIraninto
wastheregulator.Despitemyswaggering confidence, Iwasn’t able to outwit it. Itreally does not want to pull
too much O2 out of the air.The lowest I could get it towas 15 percent.After that, itflatlyrefusedtogolower,andnothing I didmattered. I hadall these plans about gettinginandreprogramming it.Butthe safety protocols turnedouttobeinROMs.I can’t blame it. Its whole
purpose is to prevent theatmosphere from becominglethal. Nobody at NASA
thought, “Hey, let’s allow afatal lackofoxygen thatwillmakeeveryonedropdead!”So I had to use a more
primitiveplan.The regulator uses a
different set of vents for airsampling than it does formain air separation. The airthat gets freeze-separatedcomes in through a singlelarge vent on the main unit.But it samples the air from
nine small vents that pipeback to the main unit. Thatwayitgetsagoodaverageofthe Hab, and one localizedimbalancewon’tthrowitoff.I taped up eight of the
intakes, leaving only one ofthemactive.ThenItapedthemouth of a Hefty-sized bagover the neck-hole of aspacesuit (Johanssen’s thistime).In thebackof thebag,I poked a small hole and
taped it over the remainingintake.Then I inflated the bag
with pureO2 from the suit’stanks. “Holy shit!” theregulator thought, “I betterpullO2outrightaway!”Workedgreat!I decided not to wear a
space suit after all. Theatmospheric pressure wasgoingtobefine.AllIneeded
wasoxygen.SoIgrabbedanO2canisterandbreathermaskfrom the medical bay. Thatway,Ihadahellofalotmorefreedom of motion. It evenhad a rubber band to keep itonmyface!Though Ididneeda space
suittomonitortheactualHaboxygen level, now that theHab’s main computer wasconvinced itwas100percent
O2. Let’s see…Martinez’sspace suit was in the rover.Johanssen’s was outwittingthe regulator. Lewis’s wasserving as a water tank. Ididn’t want to mess withmine (hey, it’s custom-fitted!). That left me twospacesuitstoworkwith.IgrabbedVogel’s suit and
activated the internal airsensors while leaving thehelmet off. Once the oxygen
dropped to 12 percent, I putthe breather mask on. Iwatched it fall further andfurther. When it reached 1percent, I cut power to theregulator.I may not be able to
reprogramtheregulator,butIcan turn the bastard offcompletely.The Hab has emergency
flashlights in many locationsin case of critical power
failure. I tore the LED bulbsout of one and left the twofrayedpowerwiresveryclosetogether.Now,whenIturnediton,Igotasmallspark.Taking a canister of O2
fromVogel’s suit, I attachedastraptobothendsandslungit over my shoulder. Then Iattachedanairlinetothetankand crimped it with mythumb. I turned on a very
slow trickle of O2; smallenough that it couldn’toverpowerthecrimp.Standing on the tablewith
asparkerinonehandandmyoxygen line in the other, Ireachedupandgaveitatry.And holy hell, it worked!
Blowing the O2 over thesparker, I flicked the switchon the flashlight and awonderful jet of flame fired
outofthetube.Thefirealarmwent off, of course. But I’dheard it so much lately, Ibarelynoticeditanymore.Then I did it again. And
again. Short bursts. Nothingflashy. I was happy to takemytime.Iwas elated!Thiswas the
bestplanever!NotonlywasIclearing out the hydrogen, Iwasmakingmorewater!
Everythingwentgreatrightuptotheexplosion.
One minute I was happilyburning hydrogen; the next Iwas on the other side of theHab, and a lot of stuff wasknocked over. I stumbled tomy feet and saw the Hab indisarray.Myfirst thoughtwas:“My
earshurtlikehell!”Then I thought, “I’m
dizzy,” and fell tomyknees.Then I fell prone. Iwas thatdizzy.Igropedmyheadwithboth hands, looking for ahead wound I desperatelyhoped would not be there.Nothingseemedtobeamiss.But feeling all over my
head and face revealed thetrue problem. My oxygenmask had been ripped off inthe blast. I was breathingnearlypurenitrogen.
The floor was covered injunk from all over the Hab.No hope of finding themedicalO2 tank.Nohopeoffindinganything in thismessbeforeIpassedout.Then I saw Lewis’s suit
hanging right where itbelonged. It hadn’tmoved intheblast.Itwasheavytostartwith and had 70 liters ofwaterinit.
I rushed over, quicklycrankedon theO2, and stuckmy head into the neck hole(I’dremovedthehelmetlongago, for easy access to thewater). I breathed a bit untilthedizzinessfaded,thentookadeepbreathandheldit.Still holding my breath, I
glancedovertothespacesuitand Hefty bag I’d used tooutsmart the regulator. Thebad news is I’d never
removed them. The goodnews is the explosionremoved them. Eight of thenine intakes for the regulatorwerestillbagged,butthisonewouldatleasttellthetruth.Stumbling over to the
regulator,Iturneditbackon.After a two-second boot
process (itwasmade to startup fast for obvious reasons),it immediately identified theproblem.
The shrill low-oxygenalarm blared throughout theHab as the regulator dumpedpure oxygen into theatmosphereasfastasitsafelycould. Separating oxygenfrom the atmosphere isdifficultandtime-consuming,butadding it is as simple asopeningavalve.I clambered over debris
back to Lewis’s space suitand putmy head back in for
more good air. Within threeminutes, the regulator hadbroughttheHaboxygenbackuptopar.I noticed for the first time
howburnedmyclothingwas.It was a good time to bewearing three layers ofclothes. Mostly the damagewasonmysleeves.Theouterlayer was gone. The middlelayer was singed and burnedclean through in places. The
innerlayer,myownuniform,was in reasonably goodshape.LookslikeIluckedoutagain.Also,glancingattheHab’s
main computer, I saw thetemperature had gone up to15°C. Something very hotand very explodey hadhappened, and I wasn’t surewhat.Orhow.And that’s where I am
now. Wondering what the
hellhappened.After all that work and
getting blown up, I’mexhausted. Tomorrow I’llhave to do a millionequipment checks and try tofigureoutwhatexploded,butfornowIjustwanttosleep.I’m in the rover again

LOGENTRY:SOL41
I spent the day running fulldiagnostics on every systemin theHab. Itwas incrediblyboring, but my survivaldepends on these machines,
so it had to be done. I can’tjust assume an explosion didnolong-termdamage.Idid themostcritical tests
first. Number one was theintegrityoftheHabcanvas.Ifeltprettyconfident itwas ingoodshape,becauseI’dspenta few hours asleep in therover before returning to theHab, and the pressure wasstill good. The computerreported no change in
pressureover that time,otherthan a minor fluctuationbasedontemperature.Then I checked the
oxygenator. If that stopsworkingandIcan’tfixit,I’madeadman.Noproblems.Then the atmospheric
regulator.Again,noproblem.Heating unit, primary
battery array, O2 and N2storage tanks, water
reclaimer, all three airlocks,lighting systems, maincomputer…onandonIwent,feeling better and better aseach system proved to be inperfectworkingorder.Got to hand it to NASA.
They don’t screw aroundwhenmakingthisstuff.Then came the critical
part…checking the dirt. Itook a few samples from allover theHab (remember, it’s
all dirt flooring now) andmadeslides.Withshakinghands,Iputa
slideintothemicroscopeandbrought the image up on-screen. There they were!Healthy,activebacteriadoingtheir thing! Looks like Iwon’tbestarvingtodeathonSol 400 after all. I ploppeddown in a chair and let mybreathingreturntonormal.Then I set about cleaning
up themess.And I had a lotof time to think about whathadhappened.Sowhathappened?Well,I
haveatheory.According to the main
computer, during the blast,theinternalpressurespikedto1.4 atmospheres, and thetemperature rose to 15°C inunder a second. But thepressure quickly subsidedback to 1 atm. This would
makesenseiftheatmosphericregulatorwereon,butI’dcutpowertoit.The temperature remained
at 15°C for some timeafterward, so any heatexpansion should still havebeenpresent.Butthepressuredropped down again, sowhere did that extra pressurego? Raising the temperatureandkeepingthesamenumberof atoms inside should
permanently raise thepressure.Butitdidn’t.I quickly realized the
answer. The hydrogen (theonly available thing to burn)combinedwithoxygen(hencecombustion) and becamewater. Water is a thousandtimes as dense as a gas. Sothe heat added to thepressure, and thetransformation of hydrogenand oxygen into water
broughtitbackdownagain.Themilliondollarquestion
is, where the hell did theoxygen come from? Thewhole plan was to limitoxygen and keep anexplosion from happening.And itwasworkingforquiteawhilebeforeblowingup.I think I have my answer.
And it comes down to mebrain-farting. RememberwhenIdecidednot toweara

Do you know how muchoxygenyouabsorboutoftheair when you take a normalbreath? I don’t know either,but it’s not 100 percent.EverytimeIexhaled,Iaddedmoreoxygentothesystem.

off most of the hydrogenbefore the explosion.
Otherwise that would havebeen the end. As it is, theexplosion wasn’t strongenough to pop the Hab.Though itwasstrongenoughto almost blast my eardrumsin.This all started with me

VENKAT KAPOOR returned tohis office, dropped hisbriefcase on the floor, andcollapsed into his leatherchair. He took a moment tolook out the windows. Hisoffice in Building 1 affordedhim a commanding view of
thelargeparkinthecenterofthe Johnson Space Centercomplex.Beyondthat,dozensof scattered buildingsdominated the view all theway to Mud Lake in thedistance.Glancing at his computer
screen, he noted forty-sevenunread e-mails urgentlydemanding his attention.They could wait. Today hadbeen a sad day. Today was
the memorial service forMarkWatney.The President had given a
speech, praising Watney’sbraveryandsacrifice,andthequick actions of CommanderLewis in getting everyoneelse to safety. CommanderLewisandthesurvivingcrew,via long-rangecommunicationfromHermes,gave eulogies for theirdeparted comrade from deep

given a speech as well,reminding everyone thatspace flight is incrediblydangerous, and that we willnotbackdown in the faceofadversity.They’daskedVenkat ifhe

point? Watney was dead.Nicewords from thedirectorof Mars operations wouldn’tbringhimback.“Youokay,Venk?”camea
familiar voice from thedoorway.Venkat swiveled around.
“Guessso,”hesaid.Teddy Sanders swept a

adjusting his cuff links.“Let’s get back to work,
then.”“Sure.” Venkat shrugged.
“Let’s start with youauthorizing my satellitetime.”Teddy leaned against the

Venkat leaned forward.“Ares3wasafailure,butwecan salvage something fromit.We’refundedforfiveAresmissions. I think we can getCongresstofundasixth.”“Idon’tknow,Venk…”“It’s simple, Teddy.”

“Like what? You thinkwe’d send people to Marswithoutbeingsureeverythingwas in perfect workingorder?”“Everything doesn’t have

Venkat froze. “Then…but…what…”Teddy turned to face him.
“We’re a public domainorganization.There’snosuchthing as secret or secureinformationhere.”“So?”“Any imagery we take
goesdirectlytothepublic.”“Again,so?”“MarkWatney’sbodywill
be within twenty meters ofthe Hab. Maybe partiallyburied in sand, but still veryvisible, and with a commantenna sticking out of hischest. Any images we takewillshowthat.”Venkatstared.Thenglared.
“This is why you denied myimagery requests for twomonths?”“Venk,comeon—”
“Really, Teddy?” he said.“You’re afraid of a PRproblem?”“The media’s obsession
withWatney’sdeathisfinallystarting to taper off,” Teddysaid evenly. “It’s been badpress after bad press for twomonths. Today’s memorialgives people closure, and themedia can move on to someotherstory.Thelastthingwewant is to dredge everything
backup.”“Sowhat dowe do, then?
He’snotgoingtodecompose.He’llbethereforever.”“Not forever,”Teddy said.
“Within a year, he’ll becovered in sand fromnormalweatheractivity.”“A year?” Venkat said,
rising to his feet. “That’sludicrous. We can’t wait ayearforthis.”
“Why not? Ares 4 won’teven launch for another fiveyears.Plentyoftime.”Venkat took a deep breath
andthoughtforamoment.“Okay, consider this:
Sympathy for Watney’sfamily is really high. Ares 6could bring the body back.We don’t say that’s thepurpose of the mission, butwe make it clear that wouldbe part of it. Ifwe framed it
that way, we’d get moresupport in Congress. But notif we wait a year. In a year,peoplewon’tcareanymore.”Teddy rubbed his chin.
“Hmm…”

Ifinishedmakingwatersometime ago. I’m no longer indangerofblowingmyselfup.The potatoes are growingnicely.Nothinghasconspiredto kill me in weeks. Andseventies TV keeps me
disturbinglymore entertainedthan it should. Things arestablehereonMars.It’s time to start thinking
long-term.EvenifIfindawaytotell
NASA I’m alive, there’s noguarantee they’ll be able tosave me. I need to beproactive.IneedtofigureouthowtogettoAres4.Won’tbeeasy.
Ares 4 will be landing atthe Schiaparelli crater, 3200kilometersaway.Infact,theirMAVisalreadythere.Iknowbecause I watched Martinezlandit.It takes eighteen months
fortheMAVtomakeitsfuel,so it’s the first thing NASAsendsalong.Sendingitforty-eight months early gives itplenty of extra time in casefuel reactions go slower than
expected. But much moreimportantly, it means aprecision soft landing can bedone remotely by a pilot inorbit.DirectremoteoperationfromHoustonisn’tanoption;they’re anywhere from fourtotwentylight-minutesaway.Ares 4’s MAV spent
eleven months getting toMars.Itleftbeforeusandgotherearoundthesametimewedid. As expected, Martinez
landed it beautifully. It wasone of the last thingswe didbefore piling into our MDVand heading to the surface.Ahh,thegoodolddays,whenIhadacrewwithme.I’m lucky. Thirty-two
hundred km isn’t that bad. Itcouldhavebeenupto10,000km away. And because I’mon the flattest part of Mars,the first 650 kilometers isnice, smooth terrain (Yay
AcidaliaPlanitia!)buttherestof it is nasty, rugged, crater-pockedhell.Obviously, I’llhave touse
a rover. And guess what?They weren’t designed formassiveoverlandjourneys.This is going to be a
research effort, with a bunchof experimentation. I’ll haveto become my own littleNASA, figuring out how toexplorefarfromtheHab.The
good news is I have lots oftime to figure it out. Almostfouryears.Some stuff is obvious. I’ll
need tousea rover. It’ll takea long time, so I’ll need tobring supplies. I’ll need torechargeen route, and roversdon’t have solar cells, so I’llneed to steal some from theHab’s solar farm.During thetrip I’ll need to breathe, eat,anddrink.
Lucky for me, the techspecsforeverythingarerighthereinthecomputer.I’ll need to trick out a
rover. Basically it’ll have tobe a mobile Hab. I’ll pickRover 2 as my target. Wehave a certain bond, after Ispent two days in it duringtheGreatHydrogen Scare ofSol37.There’s too much shit to
thinkaboutallatonce.Sofor
now, I’ll just think aboutpower.Our mission had a 10-
kilometer operational radius.Knowing we wouldn’t takestraight-line paths, NASAdesigned the rovers to go 35kilometers on a full charge.That presumes flat,reasonableterrain.Eachroverhasa9000-watt-hourbattery.Step one is to loot Rover
1’s battery and install it in
Rover 2. Ta-daa! I justdoubled my full-chargerange.There’s just one
complication.Heating.Part of the battery power
goes to heating the rover.Marsisreallycold.Normally,we were expected to do allEVAs in under five hours.ButI’llbelivinginittwenty-four and a half hours a day.According to the specs, the
heating equipment soaks up400 watts. Keeping it onwouldeatup9800watthoursperday.Overhalfmypowersupply,everyday!ButIdohaveafreesource
ofheat:me.Acouplemillionyears of evolution gave me“warm-blooded” technology.I can just turn off the heaterand wear layers. The roverhas good insulation, too. It’llhave to be enough; I need
everybitofpower.According to my boring
math, moving the rover eats200watthoursof juice togo1kilometer, sousing the full18,000watthours formotion(minus a negligible amountfor computer, life support,etc.)getsme90kilometersoftravel.Nowwe’retalkin’.I’ll never actually get 90
kilometersonasinglecharge.I’ll have hills to deal with,
and rough terrain, sand, etc.But it’s a good ballpark. Ittellsme that itwould takeatleast 35daysof travel to getto Ares 4. It’ll probably bemore like 50. But that’splausible,atleast.At the rover’s blazing 25
kph top speed, it’ll take methreeandahalfhoursbeforeIrun the battery down. I candriveintwilight,andsavethesunny part of the day for
charging.This time of year Iget about thirteen hours oflight. How many solar cellswill Ihave topilfer from theHab’sfarm?Thanks to the fine
taxpayers ofAmerica, I haveover100squaremetersofthemostexpensivesolarpanelingever made. It has anastounding 10.2 percentefficiency, which is goodbecause Mars doesn’t get as
muchsunlightasEarth.Only500 to 700 watts per squaremeter (compared to the 1400Earthgets).Longstoryshort:Ineedto
bring twenty-eight squaremeters of solar cell. That’sfourteenpanels.I can put two stacks of
seven on the roof. They’llstick out over the edges, butaslongasthey’resecure,I’mhappy. Every day, after
driving, I’ll spread them outthen…wait all day.Man it’llbedull.Well it’s a start.
Tomorrow’smission:transferRover1’sbatterytoRover2.
LOGENTRY:SOL64
Sometimes things are easy,and sometimes they’re not.Getting the battery out ofRover1waseasy.Iremoved
two clamps on theundercarriage and it droppedright out. The cabling waseasy to detach, too, just acoupleofcomplicatedplugs.Attaching it to Rover 2,
however, is another story.There’snowheretoputit!The thing is huge. I was
barely able to drag it. Andthat’sinMarsgravity.It’sjusttoobig.There’sno
roomintheundercarriagefor
a second one. There’s noroom on the roof, either.That’s where the solar cellswill go. There’s no roominside the cabin, and itwouldn’t fit through theairlockanyway.But fear not, I found a
solution.For emergencies
completely unrelated to thisone, NASA provided sixsquare meters of extra Hab
canvas and some reallyimpressive resin. The samekind of resin, in fact, thatsaved my life on Sol 6 (thepatchkitIusedontheholeinmysuit).In the event of a Hab
breach, everyone would runtotheairlocks.ProcedurewastolettheHabpopratherthandietryingtopreventit.Then,we’d suit up and assess thedamage. Once we found the
breach, we’d seal it with thespare canvas and resin. Thenreinflate and we’re good asnew.The six square meters of
spare canvas was aconvenientonebysixmeters.I cut 10-centimeter-widestrips, then used them tomakeasortofharness.I used the resin and straps
to make two 10-metercircumference loops. Then I
put a big patch of canvas oneach end. I now had poorman’s saddlebags for myrover.This is getting more and
moreWagonTraineveryday.The resin sets almost
instantly.But it gets strongerifyouwaitanhour.SoIdid.Then I suited up and headedouttotherover.Idraggedthebatterytothe
side of the rover and loopedoneendoftheharnessaroundit.ThenIthrewtheotherendover the roof. On the otherside, I filled it with rocks.When the two weights wereroughly equal, I was able topulltherocksdownandbringthebatteryup.Yay!I unplugged Rover 2’s
batteryandplugged inRover1’s. Then Iwent through the
airlock to the rover andchecked all systems.Everythingwasa-okay.I drove the rover around a
bit to make sure the harnesswas secure. I found a fewlargish rocks to drive over,just to shake things up. Theharnessheld.Hellyeah.For a short time, I
wondered how to splice thesecond battery’s leads intothe main power supply. My
conclusionwas“Fuckit.”There’s no need to have a
continuous power supply.When Battery 1 runs out, Icangetout,unplugBattery1,and plug in Battery 2. Whynot? It’s a ten-minute EVA,once per day. I’d have toswap batteries again whenI’m recharging them, butagain,sowhat?I spent the rest of the day
sweeping off the solar cell
farm.Soon,Ishallbelootingit.
LOGENTRY:SOL65
The solar cells were a loteasier to manage than thebattery.They’rethin,light,andjust
lying around on the ground.And I had one additionalbonus:Iwastheonewhosetthemupinthefirstplace.
Well, okay. It wasn’t justme. Vogel and I workedtogether on it. And boy didwe drill on it. We spentalmostanentireweekdrillingonthesolararrayalone.Thenwe drilled more wheneverthey figured we had sparetime.Thearraywasmission-critical. Ifwe broke the cellsor rendered themuseless, theHabwouldn’tbeabletomakepower,andthemissionwould
end.You might wonder what
therestofthecrewwasdoingwhileweassembledthearray.TheyweresettinguptheHab.Remember, everything inmyglorious kingdom came hereinboxes.Wehad toset ituponSols1and2.Each solar cell is on a
lightweight lattice that holdsit at a 14-degree angle. I’lladmitIdon’tknowwhyit’sa

themontherover.I considered removing the
rock sample container. It’s
nothing more than a largecanvas bag attached to theroof. Way too small to holdthesolarcells.ButaftersomethoughtIleftitthere,figuringit would provide a goodcushion.The cells stacked well
(they were made to, fortransport to Mars), and thetwo stacks sat nicely on theroof.Theyhungover the leftand right edges, but I won’t

the emergency Hab material,I made straps and tied thecells down. The rover hasexternal handles near thefrontandback.They’re thereto help us load rocks on theroof. They made perfectanchorpointsforthestraps.I stood back and admired
mywork.Hey, Iearned it. It

fully charged batteries andsolar cells on the roof, driveuntil I run out of power, andseehowfarIget.
Iwon’tbeanidiot.I’mnotdriving directly away fromthe Hab. I’ll drive a half-kilometer stretch, back andforth. I’ll be within a shortwalkofhomeatalltimes.Tonight,I’llchargeupboth

Sirius1iscomplete!More accurately, Sirius 1

drove to a nice flat spot akilometer from theHab, then
started going back and forthovera500-meterstretch.I quickly realized this

drove around randomly,
making sure to stay within akilometeroftheHab.Amuchmorerealistictest.After an hour, things
started to get cold. And Imeanreallycold.The rover’s always cold
whenyoufirstgetinit.Whenyou haven’t disabled theheater, it warms up rightaway.Iexpectedittobecold,butJesusChrist!
Iwas fine forawhile.Myown body heat plus threelayers of clothing kept mewarm, and the rover’sinsulation is top-notch. Theheat that escaped my bodyjust warmed up the interior.But there’s no such thing asperfect insulation, andeventuallytheheat left to thegreat outdoors, while I gotcolderandcolder.Within an hour, I was
chatteringandnumb.Enoughwasenough.There’snowayIcoulddoalongtriplikethis.Turning the heater on, I
drove straight back to theHab.Once I got home, I sulked

heaterwilleathalfmybatterypowereveryday.Icouldturnit down, I guess. Be a littlecoldbutnotfreezingtodeath.Even then I’d still lose atleastaquarter.This will require some
thought. I have to askmyself…WhatwouldHerculePoirotdo?I’llhavetoputmy“little gray cells” towork ontheproblem.
LOGENTRY:SOL68
Well,shit.I came upwith a solution,
but…remember when Iburned rocket fuel in theHab? This’ll be moredangerous.I’mgoingtousetheRTG.The RTG (radioisotope
thermoelectricgenerator) is abigboxofplutonium.Butnotthe kind used in nuclear
bombs. No, no. Thisplutonium is way moredangerous!Plutonium-238 is an
incredibly unstable isotope.It’s so radioactive that itwillget red hot all by itself. Asyou can imagine, a materialthat can literally fry an eggwith radiation is kind ofdangerous.The RTG houses the
plutonium, catches the
radiation in the formofheat,and turns it into electricity.It’s not a reactor. Theradiation can’t be increasedor decreased. It’s a purelynatural process happening attheatomiclevel.As long ago as the 1960s,
NASA began using RTGs topower unmanned probes.Theyhave lotsofadvantagesoversolarpower.They’renotaffectedbystorms;theywork
day or night; they’re entirelyinternal, so you don’t needdelicate solar cells all overyourprobe.But they never used large
RTGs on manned missionsuntiltheAresProgram.Why not? It should be
pretty damned obvious whynot! They didn’t want to putastronauts next to a glowinghotballofradioactivedeath!
I’m exaggerating a little.The plutonium is inside abunch of pellets, each onesealed and insulated toprevent radiation leakage,even if the outer container isbreached. So for the AresProgram,theytooktherisk.An Ares mission is all
about the MAV. It’s thesingle most importantcomponent. It’s one of thefew systems that can’t be
replaced or worked around.It’s the only component thatcauses a complete missionscrubifit’snotworking.Solar cells are great in the
short term, and they’re goodfor the long termifyouhavehumansaroundtocleanthem.But the MAV sits alone foryears quietly making fuel,then just kind of hangs outuntil its crew arrives. Evendoing nothing, it needs
power,soNASAcanmonitorit remotely and run self-checks.The prospect of scrubbing
amissionbecauseasolarcellgot dirty was unacceptable.They needed a more reliablesourceofpower.SotheMAVcomes equipped with anRTG. Ithas2.6kilogramsofplutonium-238, which makesalmost 1500watts of heat. Itcanturnthatinto100wattsof
electricity.TheMAVrunsonthatuntilthecrewarrive.One hundred watts isn’t
enough to keep the heatergoing, but I don’t care aboutthe electrical output. I wantthe heat. A 1500-watt heateris so warm I’ll have to tearinsulation out of the rover tokeepitfromgettingtoohot.Assoonastheroverswere
unstowed and activated,Commander Lewis had the
joyofdisposingof theRTG.She detached it from theMAV, drove four kilometersaway,andburiedit.Howeversafe it may be, it’s still aradioactive core and NASAdidn’t want it too close totheirastronauts.The mission parameters
don’tgivea specific locationto dump the RTG. Just “atleast four kilometers away.”SoI’llhavetofindit.
I have two thingsworkingfor me. First, I wasassembling solar panels withVogel when CommanderLewis drove off, and I sawshe headed due south. Also,sheplantedathree-meterpolewith a bright green flag overwhere she buried it. Greenshows up extremely wellagainst the Martian terrain.It’s made to ward us off, incase we get lost on a rover
EVAlateron.Somyplan is:Headsouth

unusable, I’llhave tousemymutant rover for the trip. Ican make a useful testmission of it. I’ll see howwellthebatteryharnessholdsuptoarealjourney,andhowwell the solar cells do

Allaroundme therewasnothingbut dust, rocks, and endlessemptydesertinalldirections.Theplanet’sfamousredcoloris from iron oxide coatingeverything. So it’s not just a
desert.It’sadesertsooldit’sliterallyrusting.TheHabismyonlyhintof
civilization, and seeing itdisappearmademewaymoreuncomfortable than I like toadmit.Iputthosethoughtsbehind
mebyconcentratingonwhatwas in front of me. I foundthe RTG right where it wassupposed to be, fourkilometers due south of the
Hab.It wasn’t hard to find.
Commander Lewis hadburieditatopasmallhill.Sheprobablywantedtomakesureeveryone could see the flag,and it worked great! Exceptinstead of avoiding it, Ibeelined to it and dug it up.Not exactly what she wasgoingfor.Itwasalargecylinderwith
heat-sinks all around it. I
couldfeelthewarmthitgaveoff even through my suit’sgloves. That’s reallydisconcerting. Especiallywhen you know the rootcauseoftheheatisradiation.No point in putting it on
theroof;myplanwastohaveit in the cabin anyway. So Ibrought it inwithme, turnedoff the heater, then drovebacktotheHab.Inthetenminutesittookto
get home, even with theheater off, the interior of therover became anuncomfortablyhot37°C.TheRTGwoulddefinitelybeabletokeepmewarm.The trip also proved that
myriggingworked.Thesolarcells andextrabattery stayedbeautifully in place whiletraversingeightkilometersofrandomterrain.I declare Sirius 2 to be a
successfulmission!I spent the rest of the day
vandalizingtheinterioroftherover. The pressurecompartment is made ofcarboncomposite.Just insidethat is insulation, which iscovered by hard plastic. Iused a sophisticated methodto remove sections of plastic(hammer), then carefullyremoved the solid foaminsulation(hammeragain).
After tearing out someinsulation, I suited up andtook the RTG outside. Soon,the rovercooleddownagain,and I brought it back in. Iwatched as the temperatureroseslowly.Nowherenearasfastasithadonmytripbackfromtheburialsite.I cautiously removedmore
insulation (hammer) andchecked again. After a fewmore cycles of this, I had
enough insulation torn outthat the RTG could barelykeepupwithit.Infact,itwasa losing battle. Over time,heat will slowly leach out.That’s fine. Ican turnon theheater for short bursts whennecessary.I brought the insulation
pieceswithmeback into theHab. Using advancedconstruction techniques (ducttape), I reassembled some of
themintoasquare.Ifigureifthings ever get really cold, Ican tape that to a bare patchintherover,andtheRTGwillbewinningthe“heatfight.”Tomorrow,Sirius3(which
is just Sirius 1 again, butwithoutfreezing).
LOGENTRY:SOL70
Today, I write to you fromthe rover. I’m halfway
through Sirius 3 and thingsaregoingwell.I set out at first light and
drove laps around the Hab,trying to stay on untouchedground. The first batterylasted just under two hours.After aquickEVA to switchthe cables, I got back todriving. When all was saidand done, I had driven 81kilometers in 3 hours and 27minutes.
That’s very good! Mindyou, thelandaroundtheHabis really flat, as is all ofAcidalia Planitia. I have noidea what my efficiencywould be on the nastier landenroutetoAres4.Thesecondbatterystillhad
a little juice left, but I can’tjust run it down all the waybefore I stop; remember, Ineed life support whilerecharging. The CO2 gets
absorbed through a chemicalprocess, but if the fan thatpushes it isn’t working, I’llchoke. The oxygen pump isalsokindofimportant.Aftermydrive,Isetupthe
solarcells. Itwashardwork;last time I hadVogel’s help.They aren’t heavy, butthey’re awkward. Aftersetting up half of them, IfiguredoutIcoulddragthemrather than carry them, and
thatspedthingsup.Now I’m just waiting for
the batteries to recharge. I’mbored, so I’m updating thelog. I have all the Poirotbooks in my computer.That’llhelp.It’sgoingtotaketwelve hours to recharge,afterall.What’s that, you say?
Twelvehoursiswrong?Isaidthirteen hours earlier? Well,my friend, let me set you
straight.The RTG is a generator.
It’sapaltryamountofpower,compared to what the roverconsumes, but it’s notnothing. It’s one hundredwatts.It’llcutanhouroffmytotal recharge time.Why notuseit?I wonder what NASA
wouldthinkaboutmefuckingwith the RTG like this.They’d probably hide under
their desks and cuddle withtheirsliderulesforcomfort.
LOGENTRY:SOL71
As predicted, it took twelvehours to charge the batteriesto full. I came straight homeassoonastheyweredone.Time to make plans for
Sirius4.AndIthinkit’llbeamultidayfieldtrip.Looks like power and
batteryrechargingaresolved.Food’snotaproblem;there’splenty of space to storethings. Water’s even easierthan food. I need two litersperdaytobecomfortable.WhenIdomytrip toAres
4 for real, I’ll need to bringthe oxygenator. But it’s bigand I don’t want to screwwithit rightnow.SoI’ll relyon O2 and CO2 filters forSirius4.
CO2 isn’t a problem. Istarted this grand adventurewith 1500 hours of CO2filters, plus another 720 foremergency use. All systemsuse standard filters (Apollo13 taught us importantlessons). Since then, I’veused 131 hours of filter onvarious EVAs. I have 2089left. Eighty-seven days’worth.Plenty.
Oxygen’s a little trickier.The rover was designed tosupport three people for twodays, plus some reserve forsafety. So its O2 tanks canholdenoughtolastmesevendays.Notenough.Mars has almost no
atmospheric pressure. Theinside of the rover has oneatmosphere. So the oxygentanks are on the inside (lesspressure differential to deal
with).Whydoes thatmatter?It means I can bring alongother oxygen tanks, andequalize them with therover’s tanks without havingtodoanEVA.Sotoday,Idetachedoneof
the Hab’s two 25-liter liquidoxygen tanks and brought itinto the rover. According toNASA, a human needs 588liters of oxygen per day tolive.CompressedliquidO2 is
about1000 timesasdenseasgaseousO2 in a comfortableatmosphere.Longstoryshort:With the Hab tank, I haveenough O2 to last 49 days.That’llbeplenty.Sirius 4 will be a twenty-
daytrip.Thatmay seem a bit long,
but I have a specific goal inmind. Besides, my trip toAres 4 will be at least forty
days. This is a good scalemodel.While I’m away, the Hab
cantakecareofitself,butthepotatoes are an issue. I’llsaturatethegroundwithmostofthewaterIhave.Then,I’lldeactivate the atmosphericregulator, so it doesn’t pullwater out of the air. It’ll behumidashell,andwaterwillcondense on every surface.That’llkeepthepotatoeswell
wateredwhileI’maway.A bigger problem is CO2.
Thepotatoesneedtobreathe.Iknowwhatyou’re thinking.“Mark, old chap! Youproduce carbon dioxide! It’sall part of themajestic circleofnature!”Theproblemis:Wherewill
I put it? Sure, I exhale CO2witheverybreath,butIdon’thave any way to store it. I
couldturnoff theoxygenatorand atmospheric regulatorand just fill theHabwithmybreathover time.ButCO2 isdeadly to me. I need torelease a bunch at once andrunaway.Remember the MAV fuel
plant? It collects CO2 fromthe Martian atmosphere. A10-liter tank of compressedliquid CO2, vented into the
Hab, will be enough CO2 todo the trick.That’ll take lessthanadaytocreate.So that’s everything.Once
I vent theCO2 into theHab,I’ll turn off the atmosphericregulator and oxygenator,dump a ton of water on thecrops,andheadout.Sirius 4. A huge step
forwardinmyroverresearch.AndIcanstarttomorrow.

“HELLO, AND thank you forjoining us,” Cathy Warnersaidtothecamera.“TodayonCNN’sMarkWatneyReport:Several EVAs over the pastfew days…what do theymean? What progress hasNASA made on a rescue
option? And how will thisaffect the Ares 4preparations?“Joining us today is Dr.
Venkat Kapoor, director ofMars operations for NASA.Dr. Kapoor, thank you forcoming.”“A pleasure to be here,
Cathy,”Venkatsaid.“Dr. Kapoor,” Cathy said,
“Mark Watney is the most-watched man in the solar
system,wouldn’tyousay?”Venkat nodded. “Certainly
themostwatched byNASA.We have all twelve of ourMartian satellites takingpictures whenever his site’sinview.TheEuropeanSpaceAgency has both of theirsdoingthesame.”“Alltold,howoftendoyou
gettheseimages?”“Every few minutes.
Sometimes there’s a gap,based on the satellite orbits.But it’s enough that we cantrackallhisEVAactivities.”“Tell us about these latest
EVAs.”“Well,” Venkat said, “it
looks like he’s preparingRover 2 for a long trip. OnSol 64, he took the batteryfrom the other rover andattached it with a homemadesling. The next day, he
detached fourteen solar cellsand stacked them on therover’sroof.”“And then he took a little
drive, didn’t he?” Cathyprompted.“Yes he did. Sort of
aimlessly for an hour, thenback to the Hab. He wasprobablytestingit.Nexttimewe saw him was two dayslater, when he drove fourkilometers away, then back.
Another incremental test, wethink. Then, over the pastcouple of days, he’s beenstockingitupwithsupplies.”“Hmm,”Cathysaid,“most
analysts think Mark’s onlyhopeofrescueistogettotheAres4site.Doyouthinkhe’scome to the sameconclusion?”“Probably,” Venkat said.
“He doesn’t know we’rewatching. From his point of
view, Ares 4 is his onlyhope.”“Do you think he’s
planning to go soon? Heseems tobegettingreadyforatrip.”“I hope not,” Venkat said.
“There’s nothing at the siteotherthantheMAV.Noneofthe other presupplies. Itwould be a very long, verydangerous trip, and he’d beleaving the safetyof theHab
behind.”“Whywouldheriskit?”“Communication,” Venkat
said. “Once he reaches theMAV,hecouldcontactus.”“So that would be a good
thing,wouldn’tit?”“Communicationwouldbe
a great thing. But traversingthirty-twohundredkilometersto Ares 4 is incrediblydangerous. We’d rather he
stayedput.Ifwecouldtalktohim, we’d certainly tell himthat.”“Hecan’t stayput forever,
right? Eventually he’ll needtogettotheMAV.”“Not necessarily,” Venkat
said. “JPL is experimentingwith modifications to theMDV so it canmake a briefoverlandflightafterlanding.”“I’d heard that idea was
rejected as being toodangerous,”Cathysaid.“Their first proposal was,
yes.Since then, they’vebeenworking on saferways to doit.”“Withonlythreeandahalf
years before Ares 4’sscheduled launch, is thereenoughtimetomakeandtestmodificationstotheMDV?”“I can’t answer that for
sure.Butremember,wemadealunarlanderfromscratchinsevenyears.”“Excellent point.” Cathy
smiled.“Sowhatarehisoddsrightnow?”“No idea,” Venkat said.
“But we’re going to doeverything we can to bringhimhomealive.”

“Didn’t think of that. Sorry,Mindy.”Mindy looked at the table

“SorryI’mlate.”Hetookhisseat and pulled severalfolders from his briefcase.
Stacking them neatly, heopened the top one andsquared the pages within.“Let’s get started. Venkat,what’sWatney’sstatus?”“Alive and well,” Venkat
said.“Nochangefrommye-mailearliertoday.”“What about the RTG?
Does the public know aboutthatyet?”Teddyasked.Annie leaned forward. “So
far, so good,” she said. “Theimages are public, but wehave no obligation to tellthem our analysis. Nobodyhasfigureditoutyet.”“Whydidhedigitup?”“Heat, I think,” Venkat
said. “He wants to make therover do long trips. It uses alot of energy keeping warm.The RTG can heat up theinterior without soakingbattery power. It’s a good

“Mitch, your e-mail saidyouhadsomethingurgent?”“Yeah,”Mitch said. “How

Venkat said. “They canconcentrate on getting home—”“I make that call,” Mitch
said. “I’m the one whodecides what’s best for thecrew. And I say we bringthemuptospeed.”
After a few moments ofsilence, all eyes turned toTeddy.He thought for a moment.
“Sorry, Mitch, I’m withVenkaton thisone,”he said.“But as soon aswe come upwithaplanforrescue,wecantell Hermes. There needs tobe some hope, or there’s nopointintellingthem.”“Bullshit,” Mitch

start starving in a year. Wehave to send him supplies.Simpleasthat.”“What about an Ares 4
presupply?” said Teddy.“LanditatAres3instead.”“That’s what we’re
thinking, yeah,” Venkatconfirmed. “Problem is, theoriginal plan was to launchpresuppliesayear fromnow.They’renotreadyyet.
“It takes eight months toget a probe to Mars in thebest of times. The positionsof Earth and Mars rightnow…it’s not the best oftimes.We figure we can getthere in nine months.Presuming he’s rationing hisfood, he’s got enough to lastthree hundred and fiftymoredays.Thatmeansweneed tobuild a presupply in threemonths. JPL hasn’t even

Venkat said. “The only wayto get a probe to Mars withthe planets in their currentpositions is to spend a butt-load of fuel. We only haveone booster capable of doingthat. The Delta IX that’s onthe pad right now for the
EagleEye 3 Saturn probe.We’ll have to steal that. Italked toULA, and they justcan’tmakeanotherboosterintime.”“TheEagleEye3teamwill

Mindysaid.“No bother,” Venkat said.
“I could use a break.What’sup?”“He’s on the move,” she

“Maybeit’sjustalongertest?An overnight trip kind ofthing?”“He’s seventy-six

“WELCOME BACK,” Cathy said
to the camera. “We’rechatting with MarcusWashington, from the USPostal Service. So, Mr.Washington, Iunderstand theAres 3 mission caused apostal service first. Can youexplainthattoourviewers?”“Uh yeah,” said Marcus.
“Everyone thought MarkWatney was dead for overtwomonths. In that time, thepostalservice issueda runof
commemorative stampshonoring his memory.Twenty thousand wereprinted and sent to postofficesaroundthecountry.”“And then it turnedouthe

“Has this ever happenedbefore?”Cathyasked.“No. Not once in the

But like I said, thousandsweresold.They’llberare,butnotsuper-rare.”Cathy chuckled then
addressed the camera.
“We’ve been speaking withMarcus Washington of theUnited States Postal Service.Ifyou’vegotaMarkWatneycommemorative stamp, youmight want to hold on to it.Thanks for dropping by,Mr.Washington.”“Thanks for having me,”
Marcussaid.“Our next guest is Dr.
Irene Shields, flightpsychologist for the Ares
missions. Dr. Shields,welcometotheprogram.”“Thank you,” Irene said,
adjusting her microphoneclip.“Do you know Mark
Watneypersonally?”“Of course,” Irene said. “I
did monthly psychevaluations on each memberofthecrew.”“What can you tell us
about him? His personality,hismind-set?”“Well,” Irene said, “he’s
very intelligent. All of themare, of course. But he’sparticularly resourceful andagoodproblem-solver.”“That may save his life,”
Cathyinterjected.“It may indeed,” Irene
agreed. “Also, he’s a good-natured man. Usually
cheerful,withagreatsenseofhumor. He’s quick with ajoke. In the months leadingup to launch, the crew wasput through a gruelingtraining schedule. They allshowed signs of stress andmoodiness. Mark was noexception, but the way heshowed itwas to crackmorejokes and get everyonelaughing.”“He sounds like a great
guy,”Cathysaid.“He really is,” Irene said.
“He was chosen for themissioninpartbecauseofhispersonality.AnArescrewhasto spend thirteen monthstogether.Socialcompatibilityiskey.Marknotonlyfitswellin any social group, he’s acatalyst to make the groupwork better. Itwas a terribleblow to the crew when he‘died.’”
“And they still think he’sdead, right? The Ares 3crew?”“Yes, they do,
unfortunately,” Ireneconfirmed. “The higher-upsdecidedtokeepitfromthem,at least for now. I’m sure itwasn’taneasydecision.”Cathy paused for a
moment,thensaid,“Allright.You know I have to ask:What’s going through his
head right now?Howdoes aman like Mark Watneyrespond to a situation likethis?Stranded,alone,noideawe’retryingtohelp?”“There’s no way to be

yes,”Irenesaid.“Isthereanother?”Irene carefully formed her
answer before speaking.“When facing death, peoplewant tobeheard.Theydon’twant to die alone. He might
just want the MAV radio sohe can talk to another soulbeforehedies.“Ifhe’slosthope,hewon’t
care about survival.His onlyconcern will be making it tothe radio. After that, he’llprobably take an easier wayout than starvation. Themedical supplies of an Aresmission have enoughmorphinetobelethal.”After several seconds of

“HEYA, VENK.” Bruce’s voicecame from the speakerphoneonVenkat’sdesk.“Bruce, hi,” said Venkat,
typing on his computer.
“Thanksforclearingupsometime. I wanted to talk aboutthepresupply.”“Sure thing. What’s on

It’s theeveningofmyeighthdayon the road.Sirius4hasbeenasuccesssofar.I’ve fallen into a routine.
Every morning I wake up atdawn. First thing I do ischeckoxygenandCO2levels.
Then I eat a breakfast packand drink a cup of water.After that, I brush my teeth,using as little water aspossible, and shave with anelectricrazor.Theroverhasnotoilet.We

whenyouspendalotoftimein space, you learn how toshitinabag.Andifyouthinkthings are bad after openingthe piss box, imagine thesmellafterIdropanchor.After I’m done with that
lovely routine, I go outsideand collect the solar cells.Why didn’t I do it theprevious night? Becausetrying to dismantle and stacksolar cells in total darkness
isn’t fun. I learned that thehardway.After securing the cells, I
come back in, turn on someshitty seventies music, andstartdriving.Iputteralongat25kph,therover’stopspeed.It’scomfortableinside.Iwearhastily made cutoffs and athin shirt while the RTGbakes the interior. When itgets too hot I detach theinsulation duct-taped to the

Howfuckedupisthat?I have shitty seventies TV

It’ll probablytake fifty days. I’ll need thewater reclaimer and theoxygenator, maybe some oftheHab’smainbatteries,thena bunch more solar cells to

LOGENTRY:SOL80
Bymy reckoning, I’m about100 kilometers fromPathfinder. Technically it’s“Carl Sagan MemorialStation.” But with all due
respect to Carl, I can call itwhatever thehellIwant.I’mtheKingofMars.AsImentioned,it’sbeena
long, boring drive. And I’mstill on the outward leg. Buthey, I’m an astronaut. Long-asstripsaremybusiness.Navigationistricky.TheHab’snavbeacononly
reaches40kilometers, so it’suselesstomeouthere.Iknewthat’dbeanissuewhenIwas
planning this little road trip,so I came upwith a brilliantplanthatdidn’twork.The computer has detailed
maps, so I figured I couldnavigateby landmarks. Iwaswrong. Turns out you can’tnavigateby landmarks ifyoucan’t find any god damnedlandmarks.Our landing site is at the
delta of a long-gone river.NASA chose it because if
there are any microscopicfossils to be had, it’s a goodplacetolook.Also,thewaterwouldhavedraggedrockandsoil samples from thousandsof kilometers away. Withsomedigging,wecouldgetabroadgeologicalhistory.That’s great for science,
but it means the Hab’s in afeaturelesswasteland.I considered making a

plenty of electricity, and themed kit has a needle. Onlyone problem: Mars doesn’thaveamagneticfield.SoInavigatebyPhobos.It

Valley opened into a wideplain. So, again, I was leftwithout references and reliedon Phobos to guide me.There’s probably symbolismthere. Phobos is the god of
fear,andI’mlettingitbemyguide.Notagoodsign.But today,my luck finally
changed. After two solswanderingthedesert,Ifoundsomething to navigate by. Itwas a five-kilometer crater,sosmallitdidn’tevenhavealistedname.Butitwasonthemaps, so to me it was theLighthouse of Alexandria.OnceIhaditinsight,IknewexactlywhereIwas.

LOGENTRY:SOL81
Almostmadeit toPathfindertoday, but I ran out of juice.Just another 22 kilometers togo!An unremarkable drive.
Navigationwasn’taproblem.As Lighthouse receded intothe distance, the rim ofHamelin crater came intoview.I left Acidalia Planitia
behind a long time ago. I’mwell into Ares Vallis now.The desert plains are givingway to bumpier terrain,strewnwith ejecta that nevergot buried by sand. Itmakesdrivingachore;Ihavetopaymoreattention.Up till now, I’ve been

good. No discernible wind,nostorms.IthinkIgotluckythere. There’s a good chancemyrovertracksfromthepastfew sols are intact. I should
be able to get back to LewisValley just by followingthem.After setting up the solar
panels today, I went for alittle walk. I never left sightof the rover; the last thing Iwanttodoisgetlostonfoot.But I couldn’t stomachcrawling back into thatcramped, smelly rat’s nest.Notrightaway.It’s a strange feeling.
Everywhere I go, I’m thefirst. Step outside the rover?First guy ever to be there!Climb a hill? First guy toclimb that hill! Kick a rock?That rock hadn’tmoved in amillionyears!I’m the first guy to drive
long-distance on Mars. Thefirst guy to spendmore thanthirty-one sols onMars. Thefirst guy to grow crops onMars.First,first,first!
I wasn’t expecting to befirst at anything. I was thefifth crewman out of theMDV when we landed,making me the seventeenthperson to set foot on Mars.The egress order had beendetermined years earlier. Amonth before launch, we allgot tattoos of our “Marsnumbers.” Johanssen almostrefused to get her “15”because she was afraid it
would hurt. Here’s a womanwho had survived thecentrifuge, the vomit comet,hard-landing drills and 10kruns. A woman who fixed asimulated MDV computerfailure while being spunaroundupside-down.But shewasafraidofatattooneedle.Man,Imissthoseguys.Jesus Christ, I’d give

Anyone, anywhere. Aboutanything.I’m the first person to be

Tomorrow I’ll be the firstperson to recover a Marsprobe.
LOGENTRY:SOL82
Victory!Ifoundit!I knew I was in the right
area when I spotted Twin
Peaks in the distance. Thetwo small hills are under akilometer from the landingsite. Even better, they wereonthefarsideofthesite.AllIhadtodowasaimforthemuntilIfoundthelander.And there it was! Right
where itwassupposed tobe!I excitedly stumbled out andrushedtothesite.Pathfinder’s final stage of
descent was a balloon-
covered tetrahedron. Theballoons absorbed the impactof landing. Once it came torest, they deflated, and thetetrahedronunfoldedtorevealtheprobe.It’s actually two separate
components. The landeritself, and the Sojournerrover. The lander wasimmobile, while Sojournerwandered around and got agood look at the local rocks.
I’m taking both back withme, but the important part isthelander.That’sthepartthatcancommunicatewithEarth.Ican’texplainhowhappyI
was to find it. Itwasa lot ofwork to get here, and I’dsucceeded.Thelanderwashalf-buried.
With some quick and carefuldigging,Iexposedthebulkofit, though the largetetrahedron and the deflated
balloons still lurked belowthesurface.After a quick search, I
found Sojourner. The littlefella was only two metersfrom the lander. I vaguelyrememberitwasfartherawaywhen they last saw it. Itprobably entered acontingencymodeandstartedcircling the lander, trying tocommunicate.I quickly deposited
Sojourner in my rover. It’ssmall, light, and easily fit intheairlock.The landerwasadifferentstory.Ihadnohopeofgettingthe
whole thingback to theHab.Itwasjusttoobig,butIonlyneededtheprobeitself.Itwastime for me to put on mymechanicalengineerhat.The probe was on the
central panel of the unfoldedtetrahedron. The other three
sides were each attached tothecentralpanelwithametalhinge.Asanyoneat JPLwilltell you, probes are delicatethings. Weight is a seriousconcern, so they’re notmadeto stand up to muchpunishment.When I took a crowbar to
thehinges, theypopped rightoff!Then things got difficult.
WhenItriedtoliftthecentral
panel assembly, it didn’tbudge.Just like the other three
panels, the central panel haddeflated balloons underneathit.Over the decades, the
balloonshadrippedandfilledwithsand.Icouldcutofftheballoons,
but I’d have to dig to get tothem.Itwouldn’tbehard,it’s
just sand.But theother threepanelswereinthedamnway.I quickly realized I didn’t
give a crap about theconditionof theotherpanels.Iwent back tomy rover, cutsome strips of Hab material,then braided them into aprimitive but strong rope. Ican’t take credit for it beingstrong.ThankNASAforthat.Ijustmadeitrope-shaped.I tied one end to a panel
and the other to the rover.The rover was made fortraversing extremely ruggedterrain, often at steep angles.Itmaynot be fast, but it hasgreat torque. I towed thepanel away like a redneckremovingatreestump.Now I had a place to dig.
As I exposed each balloon, Icutitoff.Thewholetasktookanhour.Then I hoisted the central
panel assembly up andcarried it confidently to therover!At least, that’s what I
wantedtodo.Thedamnthingis still heavy as hell. I’mguessing it’s 200 kilograms.Even inMars’sgravity that’sa bit much. I could carry itaround the Hab easilyenough, but lifting it whilewearing an awkward EVAsuit?Outofthequestion.
SoIdraggedittotherover.Now for my next feat:
gettingitontheroof.The roofwas empty at the
moment. Even with mostlyfullbatteries,Ihadsetupthesolar cells when I stopped.Whynot?Freeenergy.I’d worked it out in
advance. On the way here,two stacks of solar panelsoccupied the whole roof. On
thewayback,I’lluseasinglestack to make room for theprobe. It’s a little moredangerous; the stack mightfall over.Also, the cellswillbe a pain in the ass to stackthathigh.ButI’llgetitdone.I can’t just throw a rope
over the rover and hoistPathfinderuptheside.Idon’twant to break it. Imean, it’salready broken; they lostcontact in 1997. But I don’t
wanttobreakitmore.I came upwith a solution,
but I’ddoneenoughphysicallabor for one day, and Iwasalmostoutofdaylight.Now I’m in the rover,
lookingatSojourner.Itseemsallright.Nophysicaldamageon the outside. Doesn’t looklike anything got too bakedby the sunlight. The denselayerofMarscrapallover itprotected it from long-term
solardamage.You may think Sojourner
isn’tmuchusetome.Itcan’tcommunicate with Earth.WhydoIcareaboutit?Because it has a lot of
movingparts.If I establish a link with
NASA,Ican talk to thembyholding a page of text up tothelander’scamera.Buthowwould they talk to me? The
only moving parts on thelander are the high-gainantenna(whichwouldhavetostaypointedatEarth)andthecamera boom. We’d have tocomeupwithasystemwhereNASA could talk by rotatingthecamerahead. Itwouldbepainfullyslow.But Sojourner has six
independent wheels thatrotatereasonablyfast.It’llbemuch easier to communicate
with those. I could drawletters on the wheels. NASAcould rotate them to spellthingsatme.That all assumes I can get
the lander’s radioworking atall.Time to turn in. I’vegot a
lot of backbreaking physicallabor to do tomorrow. I’llneedmyrest.
LOGENTRY:SOL83
OhGod,I’msore.But it’s the only way I
could think of to get thelandersafelyontotheroof.Ibuilt a rampoutof rocks
andsand.JustliketheancientEgyptiansdid.And if there’s one thing
AresVallishas,it’srocks!First, I experimented to
find out how steep the gradecould be. I piled some rocks
nearthelanderanddraggeditup the pile and back downagain. Then I made the pilesteeperandmadesureIcoulddragthelanderupanddown.I repeated this over and overuntil I found the best gradefor my ramp: 30 degrees.Anythingmorewastoorisky.Imightlosemygripandsendthelandertumblingdowntheramp.The roof of the rover is

easy. Then they startedfeeling heavier and heavier.Hardphysicallaborinaspacesuit is murder. Everything’smore effort because you’relugging 20 kilograms of suitaround with you, and yourmovement is limited. I was

ramp would collapse as Idrove away, and the rocksmight damage the wheels orundercarriage. I’d have totake the ramp apart to keepthatfromhappening.Ugh.

I just watched an episodewhere Steve Austin fights aRussian Venus probe thatlanded on Earth by mistake.Asanexpertininterplanetarytravel,Icantellyouthereareno scientific inaccuracies inthe story. It’s quite commonfor probes to land on thewrong planet. Also, theprobe’s large, flat-panel hullis ideal for the high-pressureVenusian atmosphere. And,

two sols and couldn’t evenwalkwithoutsuitingup.I’ll need to endure twice
that to get to Ares 4, butthat’saproblemforlater.After a few celebratory
laps around the Hab, it wastimetogettowork.First, I fired up the
oxygenator and atmosphericregulator. Checking the airlevels, everything looked
good.TherewasstillCO2,sothe plants hadn’t suffocatedwithout me exhaling forthem.Naturally I did an
exhaustive check on mycrops,andthey’reallhealthy.I addedmybagsof shit to

to spend the rest of the dayrelaxing, but I had more todo.Aftersuitingup,Iwentout
to the rover and dragged thesolar cells off the roof.Overthenextfewhours,Iputthemback where they belonged,wiring them into the Hab’spowergrid.Getting the lander off the

detached a strut from theMAVplatformanddraggeditover to the rover.By leaningitagainstthehullanddiggingtheotherend into thegroundforstability,Ihadaramp.I should have brought that
strut with me to thePathfinder site. Live andlearn.There’s no way to get the
lander in theairlock. It’s justtoo big. I could probably
dismantle it and bring it in apiece at a time, but there’s apretty compelling reason notto.With no magnetic field,
Mars has no defense againstharsh solar radiation. If Iwereexposedtoit,I’dgetsomuch cancer, the cancerwould have cancer. So theHab canvas shields fromelectromagnetic waves. Thismeans the Hab itself would

Todaywasallaboutrepairs!The Pathfinder mission
endedbecausethelanderhadan unknown critical failure.Once JPL lost contact withthe lander, they had no ideawhatbecameofSojourner. Itmight be in better shape.Maybe it just needs power.Poweritcouldn’tgetwithitssolarpanelshopelesslycakedwithdust.
I set the little roveronmyworkbench and pried open apanel to peek inside. Thebatterywas a lithium thionylchloride nonrechargeable. Ifigured that out from somesubtleclues: the shapeof theconnection points, thethickness of the insulation,and the fact that it had“LiSOCl2 NON-RCHRG”writtenonit.I cleaned the solar panels
thoroughly, then aimed asmall, flexible lamp directlyat them. The battery’s longdead.Butthepanelsmightbeokay, and Sojourner canoperate directly off them.We’ll see if anythinghappens.Then itwas time to take a
look at Sojourner’s daddy. Isuitedupandheadedout.Onmost landers, theweak
point is the battery. It’s the
mostdelicatecomponent,andwhen it dies, there’s no waytorecover.Landers can’t just shut
down and wait when theyhave low batteries. Theirelectronicswon’tworkunlessthey’re at a minimumtemperature. So they haveheaterstokeeptheelectronicswarm. It’s a problem thatrarelycomesuponEarth,buthey.Mars.
Overtime,thesolarpanelsget covered with dust. Thenwinter brings coldertemperatures and lessdaylight. This all combinesinto a big “fuck you” fromMars to your lander.Eventually it’s using morepowertokeepwarmthanit’sgetting from the meagerdaylightthatmakesitthroughthedust.Once the battery runs
down, the electronics get toocoldtooperate,andthewholesystemdies.Thesolarpanelswill recharge the batterysomewhat, but there’snothing to tell the system toreboot. Anything that couldmake that decision would beelectronics, which would notbe working. Eventually, thenow-unused battery will loseitsabilitytoretaincharge.That’s the usual cause of
death. And I sure hope it’swhatkilledPathfinder.I piled some leftover parts
of theMDVintoamakeshifttable and ramp. Then Idragged the lander up to mynew outdoor workbench.Working in an EVA suit isannoying enough. Bendingover the whole time wouldhavebeentorture.I got my tool kit and
started poking around.
Opening the outer panelwasn’t too hard and Iidentified the battery easilyenough. JPL labelseverything. It’s a 40 amp-hour Ag-Zn battery with anoptimalvoltageof1.5.Wow.Theyreallymadethosethingsrunonnothin’backthen.I detached the battery and
headedbackinside.Icheckeditwithmyelectronicskit,andsure enough it’s dead, dead,
dead.Icouldshuffleacrossacarpetandholdmorecharge.ButIknewwhatthelander

crapI’vebeengluingtogethersinceSol6,thiswasabreeze.I have voltage controllers inmy kit! It only took mefifteen minutes to put acontrolleronareservepowerline, then another hour to gooutside and run the line to
wherethebatteryusedtobe.Then there’s the issue of
heat.It’sagoodideatokeepelectronicsabove−40°C.Thetemperature today is a brisk−63°C.The battery was big and
easy to identify,but Ihadnoclue where the heaters were.Even if I knew, it’d be tooriskytohookthemdirectlytopower. I could easily fry thewholesystem.
So instead, Iwent to goodold“SpareParts”Rover1andstole its environment heater.I’veguttedthatpoorroversomuch,itlookslikeIparkeditinabadpartoftown.I lugged the heater to my

Iwas reallyhoping I’dwakeup toa functional lander,butno such luck. Its high-gainantenna is right where I lastsawit.Whydoesthatmatter?Well,I’lltellya…Ifthelandercomesbackto
life (and that’s a big if), it’lltry to establish contact withEarth. Problem is nobody’slistening. It’s not like thePathfinder team is hanging
around JPL just in case theirlong-dead probe is repairedbyawaywardastronaut.The Deep Space Network

out what was going on,especially when theytriangulated the signal tomylandingsite.
They’d tell the landerwhere Earth is, and it wouldangle the high-gain antennaappropriately. That there, theanglingoftheantenna,ishowI’llknowifitlinkedup.Sofar,noaction.There’s still hope. Any
number of reasons could bedelaying things. The roverheater is designed to heat airat one atmosphere, and thethin Martian air severely
hampers its ability to work.Sotheelectronicsmightneedmoretimetowarmup.Also, Earth is only visible
during the day. I (hopefully)fixed the lander yesterdayevening.It’smorningnow,somost of the intervening timehasbeennight.NoEarth.Sojourner’s showing no

“SOMETHING’S COMING IN…yes…yes!It’sPathfinder!”The crowded room burst

VENKAT GRINNED as he tookthe podium in the JPL press
room.“Wereceivedthehigh-gain
response just over half anhour ago,” he said to theassembled press. “Weimmediately directedPathfinder to take apanoramic image. Hopefully,Watney has some kind ofmessageforus.Questions?”Theseaof reporters raised
theirhands.“Cathy, let’s start with
you,”Venkatsaid,pointingtotheCNNreporter.“Thanks,” she said. “Have
youhadanycontactwith theSojournerrover?”“Unfortunately, no,” he
replied. “The lander hasn’tbeen able to connect toSojourner, and we have nowaytocontactitdirectly.”“What might be wrong
withSojourner?”
“I can’t even speculate,”Venkat said. “After spendingthat long on Mars, anythingcouldbewrongwithit.”“Bestguess?”“Ourbest guess is he took
it into the Hab. The lander’ssignal wouldn’t be able toreach Sojourner throughHabcanvas.” Pointing to anotherreporter, he said, “You,there.”
“MartyWest,NBCNews,”Marty said. “How will youcommunicate with Watneyonce everything’s up andrunning?”“That’llbeup toWatney,”
saidVenkat. “Allwehave toworkwith is the camera. Hecanwritenotesandholdthemup. But howwe talk back istrickier.”“Howso?”Martyasked.
“Becauseallwehaveisthecamera platform. That’s theonly moving part. There areplenty of ways to getinformation across with justtheplatform’srotation,butnoway to tell Watney aboutthem.He’ll have to come upwith something and tell us.We’llfollowhislead.”Pointing to the next
reporter,hesaid,“Goahead.”“JillHolbrook,BBC.With
a thirty-two-minute round-trip and nothing but a singlerotatingplatformtotalkwith,it’ll be a dreadfully slowconversation,won’tit?”“Yes it will,” Venkat
confirmed. “It’s earlymorning in Acidalia Planitiarightnow,andjustpast threea.m. here in Pasadena.We’llbe here all night, and that’sjust for a start. No morequestions for now. The
panorama is due back in afewminutes.We’ll keepyouposted.”Beforeanyonecouldaska
follow-up, Venkat strode outthe side door and hurrieddown the hall to themakeshift Pathfinder controlcenter. He pressed throughthe throng to thecommunicationsconsole.“Anything,Tim?”
“Totally,” he replied. “Butwe’re staring at this blackscreenbecauseit’swaymoreinteresting thanpictures fromMars.”“You’reasmart-ass,Tim,”
Venkatsaid.“Noted.”Bruce pushed his way
forward. “Still another fewseconds on the clock,” hesaid.
Thetimepassedinsilence.“Getting something,” Tim
said. “Yup. It’s thepanoramic.”Sighs of relief and muted
conversation replaced tensesilence as the image begancoming through. It filled outfrom left to right at a snail’space due to the bandwidthlimitations of the antiqueprobesendingit.
“Martian surface…,”Venkat said as the linesslowly filled in. “Moresurface…”“Edge of the Hab!” Bruce
said,pointingtothescreen.“Hab,” Venkat smiled.
“More Hab now…moreHab…Is that a message?That’samessage!”As the image grew, it
revealed a handwritten note,
suspended at the camera’sheightbyathinmetalrod.“We got a note from
Mark!”Venkat announced totheroom.Applause filled the room,
then quickly died down.“What’s it say?” someoneasked.Venkatleanedclosertothe
screen. “It says…‘I’ll writequestions here—Are you
receiving?’”“Okay…?”saidBruce.“That’s what it says,”
Venkatshrugged.“Another note,” said Tim,
pointingtothescreenasmoreoftheimagecamethrough.Venkat leaned in again.
“Thisonesays‘Pointhereforyes.’”He folded his arms. “All
right. We have
communication with Mark.Tim, point the camera at‘Yes.’ Then, start takingpictures at ten-minuteintervalsuntilheputsanotherquestionup.”

“Yes!”Theysaid,“Yes!”I haven’t been this excited
about a “yes” since promnight!
Okay,calmdown.I have limited paper to
workwith. These cardswereintended to label batches ofsamples. I have about fiftycards. I can use both sides,and if it comes down to it, Icanre-usethembyscratchingouttheoldquestion.TheSharpieI’musingwill

writing in the Hab. I don’tknow what kind ofhallucinogeniccrapthatinkismadeof,butI’mprettysureitwould boil off in Mars’satmosphere.I’m using old parts of the
antenna array to hold thecards up. There’s a certainironyinthat.We’ll need to talk faster
than yes/no questions everyhalf hour. The camera can

Each one wouldonly get 13 degrees of arc.EvenifJPLpointsthecameraperfectly, there’s a goodchance I won’t know whichlettertheymeant.
So I’ll have to useASCII.That’s how computersmanage characters. Eachcharacter has a numericalcode between 0 and 255.Values between 0 and 255can be expressed as 2hexadecimaldigits.Bygivingme pairs of hex digits, theycan send any character theylike, including numbers,punctuation,etc.How do I know which
values go with whichcharacters? BecauseJohanssen’slaptopisawealthof information. I knew she’dhave anASCII table in theresomewhere. All computergeeksdo.So I’ll make cards for 0

VENKAT BLINKED his bleary

approachingthetable.“Yes, they’re out of Diet

you,Dr.Kapoor.”“Huh?” said Venkat,
looking up. He shook hishead. “Sorry, I was up allnight.”He gulped his coffee.“Whoareyouagain?”“Jack Trevor,” said the
thin,palemanbeforeVenkat.“I work in softwareengineering.”“WhatcanIdoforyou?”“We have an idea for
communication.”“I’mallears.”“We’ve been looking
through the old Pathfindersoftware. We got duplicatecomputersupandrunningfortesting.Samecomputers they
used to find a problem thatalmost killed the originalmission. Real interestingstory,actually;turnsouttherewas a priority inversion inSojourner’s threadmanagementand—”“Focus, Jack,” interrupted
Venkat.“Right. Well, the thing is,
Pathfinder has anOS updateprocess. So we can changethe software to anything we
want.”“Howdoesthishelpus?”“Pathfinder has two
communications systems.Onetotalktous,theothertotalk to Sojourner. We canchange the second system tobroadcastontheAres3roverfrequency. Andwe can haveit pretend to be the beaconsignalfromtheHab.”“You can get Pathfinder
talkingtoMark’srover?”“It’s the only option. The
Hab’s radio is dead, but therover has communicationsequipment made for talkingto the Hab and the otherrover. Problem is, toimplement a new commsystem, both ends of it needto have the right softwarerunning. We can remotelyupdatePathfinder,butnottherover.”
“So,” Venkat said, “youcan getPathfinder to talk tothe rover, but you can’t getthe rover to listen or talkback.”“Right. Ideally, we want
our text to show up on therover screen, and whateverWatneytypestobesentbacktous.That requires a changetotherover’ssoftware.”Venkatsighed.“What’sthe
pointof thisdiscussion ifwe
can’t update the rover’ssoftware?”Jack grinned as he
continued. “We can’t do thepatch, but Watney can! Wecan just send the data, andhave him enter the updateintotheroverhimself.”“How much data are we
talkingabout?”“I have guys working on
the rover software rightnow.
Thepatch filewillbe twentymeg,minimum.Wecansendone byte to Watney everyfour seconds or so with the‘Speak&Spell.’It’dtakethreeyears of constantbroadcastingtogetthatpatchacross. Obviously, that’s nogood.”“But you’re talking tome,
so you have a solution,right?” Venkat probed,resistingtheurgetoscream.
“Ofcourse!”Jackbeamed.“Software engineers aresneaky bastards when itcomestodatamanagement.”“Enlighten me,” said
Venkat.“Here’s the clever part,”
Jack said, conspiratorially.“The rover currently parsesthe signal into bytes, thenidentifies the specificsequencetheHabsends.Thatway, natural radio waves
won’t throw off the homing.If the bytes aren’t right, theroverignoresthem.”“Okay,sowhat?”“Itmeans there’s a spot in
the code base where it’s gotthe parsed bytes. We caninsert a tiny bit of code, justtwenty instructions, to writethe parsed bytes to a log filebefore checking theirvalidity.”
“This soundspromising…,”Venkatsaid.“Itis!”Jacksaidexcitedly.
“First, we update Pathfindersoitknowshowtotalktotherover. Then, we tell Watneyexactlyhowtohacktheroversoftware to add those twentyinstructions. Then we havePathfinder broadcast newsoftware to the rover. Therover logs thebytes toa file.Finally,Watney launches the
file as an executable and theroverpatchesitself!”Venkat furrowedhisbrow,
taking in far moreinformation than his sleep-deprived mind wanted toaccept.“Um,” Jack said. “You’re
notcheeringordancing.”“So we just need to send
Watney those twentyinstructions?”Venkatasked.
“That, and how to edit thefiles.Andwheretoinsert theinstructionsinthefiles.”“Justlikethat?”“Justlikethat!”Venkat was silent for a
moment. “Jack, I’m going tobuy your whole teamautographed Star Trekmemorabilia.”“I prefer Star Wars,” he
said, turning to leave. “The

“Sothat’showyouwanttoplayit?”Lewissaid.“Justcall’emasIsee’em,

Johanssen said, staringatherscreen. “It’sgonnagetworsebeforeitgetsbetter.”The Hab canvas rippled
underthebrutalassaultastheinternal supports bent andshiveredwith each gust. Thecacophony grew louder bytheminute.“All right,” Lewis said.
“Prep for abort. We’ll go tothe MAV and hope for thebest. If the wind gets too
high,we’lllaunch.”Leaving the Hab in pairs,
they grouped up outsideAirlock 1. The driving windand sand battered them, buttheywereabletostayontheirfeet.“Visibility is almost zero,”
Lewis said. “If you get lost,home in on my suit’stelemetry. The wind’s gonnabe rougher away from theHab,sobeready.”
Pressing through the gale,they stumbled toward theMAV, with Lewis and Beckin the lead and Watney andJohanssen bringing up therear.“Hey,” Watney panted.
“Maybe we could shore uptheMAV.Make tipping lesslikely.”“How?”Lewishuffed.“Wecouldusecablesfrom

Watney,carryinghimoffintothewind.“Watney!” Johanssen

Johanssenreported.“Watney, report,” Lewis

reported. “I don’t know

“beforewelosttelemetry,hisdecompression alarm wentoff!”“Shit!” Lewis exclaimed.
“Johanssen, where did youlastseehim?”“He was right in front of

“Okay,” Lewis said.“Martinez, get to the MAVand prep for launch.Everyone else, home in onJohanssen.”“Dr. Beck,” Vogel said as
he stumbled through thestorm, “how long can aperson survivedecompression?”“Lessthanaminute,”Beck
said, emotion choking hisvoice.
“I can’t see anything,”Johanssen said as the crewcrowdedaroundher.“Line up and walk west,”
Lewis commanded. “Smallsteps. He’s probably prone;we don’t want to step overhim.”Staying in sight of one
another,theytrudgedthroughthechaos.MartinezfellintotheMAV
airlock and forced it closedagainst the wind. Once itpressurized, he quicklydoffed his suit. Havingclimbed the ladder to thecrew compartment, he slidinto the pilot’s couch andbootedthesystem.Grabbing the emergency
launch checklist with onehand, he flicked switchesrapidlywiththeother.Onebyone, the systems reported

“The MAV’s got a seven-degreetilt.It’lltipat12.3.”“Copythat,”Lewissaid.“Johanssen,” Beck said,
looking at his arm computer,“Watney’s bio-monitor sentsomething before goingoffline. My computer just
says‘BadPacket.’”“I have it, too,” Johanssen
said. “It didn’t finishtransmitting. Some data’smissing, and there’s nochecksum.Gimmeasec.”“Commander,” Martinez
said. “Message fromHouston. We’re officiallyscrubbed. The storm’sdefinitely gonna be toorough.”
“Copy,”Lewissaid.“They sent that four and a

“Continue prepping forlaunch.”“Copy,”Martinezsaid.“Beck,” Johanssen said. “I

morosely. “Blood pressurezero, pulse rate zero,temperaturenormal.”The channel fell silent for
some time. They continuedpressing forward, shufflingthrough the sandstorm,hopingforamiracle.“Temperature normal?”
Lewis said, ahintofhope inhervoice.“Ittakesawhileforthe—”
Beck stammered. “It takes awhiletocool.”“Commander,” Martinez
said. “Tilting at 10.5 degreesnow,withgustspushing it toeleven.”“Copy,” Lewis said. “Are

replied. “I can launchanytime.”“If it tips, can you launch
before it falls completelyover?”“Uh,” Martinez said, not
expecting thequestion. “Yes,ma’am. I’d take manualcontrol and go full throttle.Then I’d nose up and returntopreprogrammedascent.”“Copy that,” Lewis said.
“Everyone home in onMartinez’s suit. That’ll getyou to theMAVairlock.Getinandprepforlaunch.”“What about you,
Commander?”Beckasked.“I’m searching a little
more. Get moving. AndMartinez, if you start to tip,launch.”“YoureallythinkI’llleave

“I just ordered you to,”Lewis replied. “You three,gettotheship.”They reluctantly obeyed
Lewis’sorderandmadetheirway toward the MAV. Thepunishing wind fought themeverystepoftheway.Unable to see the ground,

theshipeverhigher,andintolow orbit. Lasting less timethan the massive first stage,and thrusting much moresmoothly, it seemed almostlikeanafterthought.Abruptly, the engine
stopped, and an oppressivecalm replaced the previouscacophony.“Main engine shutdown,”
Martinez said. “Ascent time:eight minutes, fourteenseconds. On course forHermesintercept.”Normally, an incident-free
launch would be cause forcelebration. This one earnedonly silence broken byJohanssen’sgentlesobbing.

AIRLOCK 1 SLOWLY
depressurized to 0.006atmospheres. Watney,wearing an EVA suit, stoodinsideitwaitingforthecycleto complete. He had done itliterally hundreds of times.Any apprehension he mayhave had on Sol 1 was longgone. Now it was merely aboringchorebeforeexitingtothesurface.As the depressurization
continued, the Hab’satmosphere compressed theairlock, andAL102 stretchedforthelasttime.On Sol 119, the Hab
breached.The initial tear was less
than one millimeter. Theperpendicular carbon fibersshouldhavepreventedtheripfrom growing. But countlessabuses had stretched thevertical fibers apart and
weakenedthehorizontalonesbeyonduse.ThefullforceoftheHab’s
atmosphere rushed throughthe breach.Within a tenth ofasecond,theripwasameterlong, running parallel to theseal-strip. It propagated allthewayarounduntilitmetitsstarting point. The airlockwasnolongerattachedtotheHab.The unopposed pressure
launched the airlock like acannonball as the Hab’satmosphere explosivelyescaped through the breach.Inside, the surprised Watneyslammedagainsttheairlock’sback door with the force oftheexpulsion.The airlock flew forty
meters before hitting theground. Watney, barelyrecovered from the earliershock, now endured another

brunt of the blow, the safetyglassshatteringintohundredsof small cubes. His headslammedagainsttheinsideofthe helmet, knocking himsenseless.Theairlocktumbledacross
the surface for a furtherfifteen meters. The heavypadding of Watney’s suit
savedhimfrommanybrokenbones.Hetriedtomakesenseof the situation, but he wasbarelyconscious.Finally done tumbling, the
airlockrestedonitssideamidacloudofdust.Watney,onhisback,stared
blankly upward through thehole in his shatteredfaceplate. A gash in hisforehead trickledblooddownhisface.
Regaining some of hiswits, he got his bearings.Turning his head to the side,he looked through the backdoor’s window. Thecollapsed Hab rippled in thedistance,ajunkyardofdebrisstrewn across the landscapeinfrontofit.Then, a hissing sound
reached his ears. Listeningcarefully, he realized it wasnot coming from his suit.
Somewhere in the phonebooth–sized airlock, a smallbreachwaslettingairescape.He listened intently to the
hiss, then he touched hisbroken faceplate. Then helookedoutthewindowagain.“You fucking kidding

The airlock’s on its side,and I can hear a steady hiss.Soeither it’s leakingor thereare snakes in here. Eitherway,I’mintrouble.Also, during the…
whatever the fuckhappened…I got bouncedaround like a pinball andsmashedmy faceplate.Air isnotoriously uncooperativewhen it comes to giant,gaping holes in your EVA
suit.Looks like the Hab is
completely deflated andcollapsed. So even if I had afunctional EVA suit to leavethe airlock with, I wouldn’thaveanywheretogo.Sothatsucks.I gotta think for aminute.
And I have toget out of thisEVAsuit. It’sbulky,and theairlock is cramped. Besides,it’snotlikeit’sdoingmeany

AUDIOLOGTRANSCRIPT:SOL119(3)
Things aren’t as bad as theyseem.I’mstillfucked,mindyou.
Justnotasdeeply.Notsurewhathappenedto
the Hab, but the rover’sprobably fine. It’s not ideal,but at least it’s not a leakyphonebooth.
I have a patch kit on myEVA suit, of course. Thesamekind that savedmy lifeback on Sol 6.But don’t getexcited. It won’t do the suitany good. The patch kit is acone-shaped valve withsuper-stickyresinonthewideend.It’sjusttoosmalltodealwith a hole larger than eightcentimeters. And really, ifyou have a nine-centimeterhole,you’regoingtobedead
way before you could whipoutthekit.Still, it’s an asset, and
maybeIcanuseittostoptheairlock leak. And that’s mytoppriorityrightnow.It’s a small leak.With the
faceplate gone, theEVA suitis effectively managing thewhole airlock. It’s beenaddingairtomakeupforthemissingpressure.Butit’llrunouteventually.
I need to find the leak. Ithink it’s near my feet,judging by the sound. NowthatI’moutof thesuit, Icanturnaroundandgetalook.…I don’t see anything.… I

Unfortunately, the EVAsuit is made entirely ofnonflammable materials. Sois theairlock.Myclothesarefireproof as well, even thethread.Iwasoriginallyplanningto

I just realized I do havesomething flammable: myown hair. It’ll have to do.There’s a sharp knife in thetool kit. I’ll shave some armhairsoffintoalittlepile.Next step: oxygen. I don’t

anyone who’s played with aballoon knows it’s great atbuilding up static charge.Once I do that, I should beable tomake a spark just bytouchingametaltool.Fun fact: This is exactly

I’m in a box full of burning-hair smell. It’s not a goodsmell.Onmyfirsttry,thefirelit,
but the smoke just driftedrandomly around. My ownbreathingwasscrewingitup.SoIheldmybreathandtriedagain.
My second try, the EVAsuit threw everything off.There’s a gentle flow of aircomingoutofthefaceplateasthe suit constantly replacesthemissingair.So I shut thesuit down, held my breath,and tried again. I had to bequick; the pressure wasdropping.Mythirdtry,thequickarm

Igaspedforairand turnedthe EVA suit back on. Thepressure had dropped to 0.9atmospheres during my littleexperiment. But there wasplentyofoxygenintheairforme and my hair-fire tobreathe. The suit quickly gotthingsbacktonormal.Looking at the fracture, I
see that it’s pretty tiny. Itwould be a cinch to seal itwith the suit’s patch kit, but
now that I think about it,that’sabadidea.I’ll need to do some kind
of repair to the faceplate. Idon’t knowhow just yet, butthepatchkitanditspressure-resistant resin are probablyreally important.And I can’tdoitbitbybit,either.OnceIbreak the seal on the patchkit, thebinarycomponentsoftheresinmixandIhavesixtyseconds before it hardens. I

to do it without using thepatchkit.First idea: Little Dutch
Boy. I’m licking my palmandplacingitoverthecrack.Okay…I can’t quite make
a perfect seal, so there’sairflow…getting coldernow…getting prettyuncomfortable…Okay, fuckthis.On to idea number two.
Tape!I have duct tape in my
toolbox. Let’s slap some onandseeifitslowstheflow.Iwonder how long it will lastbefore the pressure rips it.Puttingitonnow.There we go…still
holding…Lemme check the suit.…
Readouts say the pressure isstable. Looks like the duct
tapemadeagoodseal.Let’sseeifitholds.…
AUDIOLOGTRANSCRIPT:SOL119(5)
It’sbeenfifteenminutes,andthe tape is still holding.Looks like that problem issolved.Sort of anticlimactic,
really. Iwasalreadyworkingout how to cover the breachwith ice. I have two liters of
water in the EVA suit’s“hamster-feeder.” I couldhave shut off the suit’sheating systems and let theairlockcooltofreezing.ThenI’d…Well,whatever.Coulda done it with ice.
I’mjustsayin’.All right. On to my next
problem: How do I fix theEVA suit? Duct tape mightseal a hairline crack, but itcan’t hold an atmosphere of
pressure against the size ofmybrokenfaceplate.The patch kit is too small,
but still useful. I can spreadthe resin around the edge ofwherethefaceplatewas,thenstick something on to coverthehole.Problemis,whatdoI use to cover the hole?Something that can stand uptoalotofpressure.Looking around, the only
thing I see that can hold an
atmosphere is the EVA suititself. There’s plenty ofmaterial to work with, and Ican even cut it. Rememberwhen I was cutting Habcanvas into strips? Thosesame shears are right here inmytoolkit.Cuttingachunkoutofmy
EVA suit leaves it withanotherhole.ButaholeIcancontroltheshapeandlocationof.
Yeah…I think I see asolution here. I’m going tocutoffmyarm!Well,no.Notmyarm.The
EVAsuit’sarm.I’llcutrightbelow the left elbow. Then Ican cut along its length,turning it into a rectangle.It’llbebigenoughtosealthefaceplate, and it’ll be held inplacebytheresin.Material designed to
withstand atmospheric
pressure?Check.Resin designed to seal a
breach against that pressure?Check.Andwhataboutthegaping
hole on the stumpy arm?Unlike my faceplate, thesuit’smaterial is flexible. I’llpress it together and seal itwith resin. I’ll have to pressmy left arm against my sidewhile I’m in the suit, butthere’llberoom.
I’ll be spreading the resinpretty thin, but it’s literallythestrongestadhesiveknownto man. And it doesn’t havetobeaperfectseal.Itjusthastolast longenoughformetogettosafety.And where will that
“safety”be?Notadamnclue.Anyway, oneproblemat a
time. Right now I’m fixingtheEVAsuit.
AUDIOLOGTRANSCRIPT:SOL119(6)
Cutting the arm off the suitwas easy; so was cuttingalong its length to make arectangle. Those shears arestrongashell.Cleaning the glass off the
faceplatetooklongerthanI’dexpected. It’s unlikely itwould puncture EVA suitmaterial, but I’m not takinganychances.Besides, Idon’twant glass in my face when
I’mwearingit.Then came the tricky part.
Once I broke the seal on thepatchkit,Ihadsixtysecondsbeforetheresinset.Iscoopedit off the patch kit with myfingers and quickly spread itaround the rim of thefaceplate. Then I took whatwas left and sealed the armhole.I pressed the rectangle of
suit material onto the helmet
with both hands while usingmyknee to keep pressure onthearm’sseam.Iheldonuntil I’d counted
120seconds.Justtobesure.It seemed to work well.
The seal looked strong andtheresinwasrock-hard.Idid,however,gluemyhandtothehelmet.Stoplaughing.In retrospect, using my
fingers to spread the resinwasn’t the best plan.Fortunately,mylefthandwasstillfree.Aftersomegruntingandalotofprofanities,Iwasable to reach the toolbox.Once I got a screwdriver, Ichiseled myself free (feelingreallystupidthewholetime).It was a delicate processbecause I didn’twant to flaytheskinoffmyfingers.Ihadto get the screwdriver
between the helmet and theresin. I freed my hand anddidn’t draw blood, so I callthat a win. Though I’ll havehardenedresinonmyfingersfor days, just like a kidwhoplayedwithKrazyGlue.Using the arm computer, I
hadthesuitoverpressurizeto1.2 atmospheres. Thefaceplate patch bowedoutward but otherwise heldfirm. The arm filled in,
threatening to tear the newseam,butstayedinonepiece.Then I watched the
readouts to see how airtightthingswere.Answer:Notvery.It absolutely pissed the air
out.Insixtysecondsitleakedso much it pressurized thewhole airlock to 1.2atmospheres.The suit is designed for
eight hours of use. Thatworksoutto250millilitersofliquidoxygen.Justtobesafe,the suit has a full liter ofO2capacity.But that’s onlyhalfthestory.Therestoftheairisnitrogen.It’sjusttheretoaddpressure.Whenthesuitleaks,that’s what it backfills with.The suit has two liters ofliquidN2storage.Let’scallthevolumeofthe
airlocktwocubicmeters.Theinflated EVA suit probablytakesuphalfof it.So it tookfive minutes to add 0.2atmospheresto1cubicmeter.That’s285gramsofair(trustme on the math). The air inthe tanks is around 1 gramper cubic centimeter,meaning I just lost 285milliliters.The three tanks combined
had 3000 milliliters to start
with.Alotofthatwasusedtomaintain pressure while theairlockwasleaking.Also,mybreathing turned someoxygen into carbon dioxide,which was captured by thesuit’sCO2filters.Checking the readouts, I
seethatIhave410millilitersof oxygen, 738 milliliters ofnitrogen.Together,theymakealmost 1150 milliliters towork with. That, divided by
285 milliliters lost perminute…Once I’m out of the
airlock, this EVA suit willonlylastfourminutes.Fuck.
AUDIOLOGTRANSCRIPT:SOL119(7)
Okay, I’ve been thinkingsomemore.What good is going to the
rover? I’d just be trapped
thereinstead.Theextraroomwouldbenice,butI’dstilldieeventually. No waterreclaimer, no oxygenator, nofood. Take your pick; all ofthoseproblemsarefatal.I need to fix the Hab. I

repair, and my EVA suit isuseless.I’ll need another suit.
Martinez’s used to be in therover. I hauled it all thewayto the Pathfinder site andback, just in case I needed aspare.Butwhen I returned, IputitbackintheHab.
Damnit!Allright,soI’llneedtoget

I left Martinez’s near mybunk, in case I needed a suitin a hurry. Of course, afterthatsuddendecompression,itcould be anywhere. Still, it’saplacetostart.Next problem: I’m like 50

exactly smooth or reflective,so I had to look at a rippled,messed-up version of thecamera feed. Still, it wasenoughtoseewhatwasgoingon.I beelined for where the
airlock used to be. I knew
there had to be a pretty bighole there, so I’d be able toget in. I found it easily.Andboyisitanastyrip!It’sgoingtobeapainintheasstofixit.That’s when the flaws in
my plan started to revealthemselves. I only had onearm to work with. My leftarm was pinned against mybody, while the stumpy armofthesuitbouncedfreely.Soas Imoved aroundunder the
canvas, I had to usemy onegood arm to hold the canvasup.Itslowedmedown.FromwhatIcouldsee,the
interior of the Hab is chaos.Everything’s moved. Entiretables and bunks are metersaway from where theystarted. Lighter objects arewildly jumbled, many ofthem out on the surface.Everything’s covered in soilandmangledpotatoplants.
Trudging onward, I got towhereI’dleftMartinez’ssuit.To my shock, it was stillthere!“Yay!” I naively thought.
“Problemsolved.”Unfortunately,thesuitwas
pinned under a table, whichwas held down by thecollapsed canvas. If I’d hadboth arms, I could havepulled it free, but with onlyone,Ijustcouldn’tdoit.
Running low on time, Idetached the helmet. Settingit aside, I reached past thetable to getMartinez’s patchkit.Ifounditwiththehelpofthe arm-camera. I dropped itin the helmet and hauled assoutofthere.I barely made it to the
rover in time. My ears werepopping from pressure lossjust as the rover’s airlockfilled with wonderful 1-
atmosphereair.Crawling in, I collapsed
andpantedforamoment.So I’m back in the rover.
Just like I was back on theGreat Pathfinder RecoveryExpedition.Ugh.Atleastthistimeitsmellsalittlebetter.NASA’s probably pretty
worried about me by now.They probably saw theairlockmovebacktotheHab,
so they know I’m alive, butthey’llwant status.And as ithappens, it’s the rover thatcommunicates withPathfinder.I tried to send a message,
but Pathfinder isn’tresponding. That’s not a bigsurprise.It’spowereddirectlyfromtheHab,andtheHabisoffline. During my brief,panicked scramble outside, IsawthatPathfinderwasright
whereI left it,andthedebrisdidn’t reach that far out. Itshould be fine, once I get itsomepower.Asformycurrentsituation,
the big gain is the helmet.They’re interchangeable, so Ican replace my broken-assone with Martinez’s. Thestumpy arm is still an issue,but the faceplate was themain source of leaks. Andwiththefreshpatchkit,Ican
sealthearmwithmoreresin.Butthatcanwait.I’vebeen

LOGENTRY:SOL121
Got agoodnight’s sleep andmaderealprogresstoday.First thingIdidwasreseal
the arm. Last time, I had to
spread the resin pretty thin;I’d used most of it for thefaceplatepatch.But this timeI had a whole patch kit justfor the arm. I got a perfectseal.Istillonlyhadaone-armed
suit,butatleastitdidn’tleak.I’d lost most of my air
yesterday, but I had a halfhour of oxygen left. Like Isaid earlier, a human bodydoesn’t need much oxygen.
Maintainingpressurewas theproblem.Withthatmuchtime,Iwas
able to take advantageof therover’s EVA tank-refill.SomethingIcouldn’tdowiththeleakysuit.The tank-refill is an
emergency measure. Theexpecteduseoftheroveristostartwith fullEVAsuits andcome backwith air to spare.It wasn’t designed for long
trips, or even overnighters.But, just in case ofemergency, ithas refillhosesmounted on the exterior.Inside space was limitedalready, and NASAconcluded that most air-relatedemergencieswouldbeoutdoors.But refilling is slow,
slower than my suit wasleaking.So itwasn’t anyuseto me until I swapped
helmets. Now, with a solidsuit capable of holdingpressure, refilling the tankswasabreeze.After refilling,andmaking
sure the suit was still notleaking, I had a fewimmediate tasks to take careof. Much as I trust myhandiwork, I wanted a two-armedsuit.I ventured back into the
Hab. This time, not being
rushed, I was able to use apole to leverage the tableoffMartinez’s suit. Pulling itloose,Idraggeditbacktotherover.Afterathoroughdiagnostic
to be sure, I finally had afully functional EVA suit! Ittook me two trips to get it,butIgotit.Tomorrow,I’llfixtheHab.

The first thing I did todaywas line up rocks near therovertospell“A-okay.”ThatshouldmakeNASAhappy.I went into the Hab again
toassessdamage.Myprioritywill be to get the structureintact and holding pressure.From there, I can work onfixingstuffthatbroke.The Hab is normally a
dome, with flexible supportpoles maintaining the arch
and rigid, folding floormaterial tokeep its base flat.The internal pressure was avital part of its support.Without it, the whole thingcollapsed. I inspected thepoles, and none of them hadbroken.They’rejustlyingflatisall. I’llhavetore-coupleafew of them, but that’ll beeasy.The hole where Airlock 1
used to be is huge, but
surmountable. I have seal-strips and spare canvas. It’llbealotofwork,butIcangettheHab togetheragain.OnceI do, I’ll reestablish powerand get Pathfinder backonline. From there, NASAcan tell me how to fixanythingIcan’tfigureoutonmyown.I’m notworried about any
of that. Ihaveamuchbiggerproblem.
Thefarmisdead.With a complete loss of
pressure, most of the waterboiled off. Also, thetemperature is well belowfreezing. Not even thebacteria in the soil cansurvive a catastrophe likethat. Someof the cropswereinpop-tentsoff theHab.Butthey’redead, too. Ihad themconnecteddirectlytotheHabvia hoses to maintain air

Rich rarely had towork late.His jobwas to find theexactorbits and course correctionsneededforanygivenmission.
Usually,itwasoneofthefirstpartsofaproject,alltheothersteps being based on theorbit.But this time, things were
reversed. Iris needed anorbital path, and nobodyknewwhenitwouldlaunch.Planetsmove as time goes

said Maurice. “But it’s notideal. EagleEye 3 was set tolaunch. Boosters aren’tdesignedtostanduprightandbear the stress of gravity forlong periods. We’re adding
external supports that we’llremove before launch. It’seasierthandisassembly.Alsothe fuel is corrosive to theinternal tanks, so we had todrain it. In the meantime,we’re performing inspectionson all systems every threedays.”“Good, thank you,” Teddy

sighed. “We’ve been at ittwenty-ninedays;soweonlyhavenineteenleft.Afterthat,thePadneedsthirteendaystomount it on the booster.We’re at least two weeksbehind.”“Is that as far behind as
you’re going to get?” Teddyasked, writing a note on hispapers. “Or will you slip

Teddysaid.“Fifteen days,” Bruce
responded.“Ifwehadanotherfifteen days, I’m sure wecouldgetitdoneintime.”
“All right,” Teddy said,taking another note. “Let’screatefifteendays.”Turninghisattentiontothe
Ares 3 flight surgeon,Teddyasked, “Dr. Keller, can wereduceWatney’s food intaketo make the rations lastlonger?”“Sorry, but no,” Keller
said. “He’s already at aminimal calorie count. Infact, considering the amount
of physical labor he does,he’s eating far less than heshould.Andit’sonlygoingtoget worse. Soon his entirediet will be potatoes andvitamin supplements. He’sbeen saving protein-richrationsfor lateruse,buthe’llstillbemalnourished.”“Onceherunsoutoffood,
how long until he starves todeath?”Teddyasked.“Presuminganamplewater
supply, he might last threeweeks.Shorter than a typicalhunger strike, but rememberhe’ll be malnourished andthintobeginwith.”Venkat raised a hand and
caught their attention.“Remember,Irisisatumbler;hemighthave todrivea fewdays to get it. And I’mguessingit’shardtocontrolarover when you’re literallystarvingtodeath.”
“He’s right,” Dr. Kellerconfirmed.“Withinfourdaysof running out of food, he’llbarelybeabletostandup,letalone control a rover. Plus,his mental faculties willrapidly decline. He’d have ahard time even stayingawake.”“So the landing date’s
firm,” Teddy said. “Maurice,can you get Iris on thebooster in less than thirteen
days?”Maurice leanedagainst the
wall and pinched his chin.“Well…it only takes threedaystoactuallymountit.Thefollowing ten are for testingandinspections.”“How much can you
reducethose?”“With enough overtime, I
couldget themountingdownto two days. That includes
transport from Pasadena toCape Canaveral. But theinspections can’t beshortened. They’re time-based. We do checks andrechecks with set intervalsbetween them to see ifsomething deforms orwarps.If you shorten the intervals,you invalidate theinspections.”“How often do those
inspections reveal a
problem?”Teddyasked.A silence fell over the
room.“Uh,”Maurice stammered.
“Areyousuggestingwedon’tdotheinspections?”“No,” said Teddy. “Right
now I’m asking how oftentheyrevealaproblem.”“About one in twenty
launches.”Teddy wrote that down.
“And how often is theproblem they find somethingthat would have caused amissionfailure?”“I’m, uh, not sure.Maybe
halfthetime?”He wrote that down as
well. “So if we skipinspections and testing, wehaveaoneinfortychanceofmission failure?” Teddyasked.
“That’s two point fivepercent,” Venkat said,steppingin.“Normally,that’sgroundsforacountdownhalt.We can’t take a chance likethat.”“‘Normally’ was a long

WHEN DESIGNING Iris, JPLaccounted for catastrophiclanding failure. Rather thannormalmealkits,mostofthefood was cubed protein barmaterial,whichwouldstillbeedible even if Iris failed to
deploy its tumble balloonsand impacted at incrediblespeed.Because Iris was an
unmannedmission,therewasno cap on acceleration. Thecontentsoftheprobeenduredforces no human couldsurvive.ButwhileNASAhadtested the effects of extremeg-forces on protein cubes,they had not done so with asimultaneous lateral
vibration. Had they beengivenmore time, theywouldhave.The harmless shimmy,
caused by a minor fuelmixtureimbalance,rattledthepayload. Iris,mounted firmlywithin the aeroshell atop thebooster, held firm. Theprotein cubes inside Iris didnot.At the microscopic level,
the protein cubes were solid
food particles suspended inthick vegetable oil. The foodparticles compressed to lessthan half their original size,buttheoilwasbarelyaffectedat all. This changed thevolumeratioofsolidtoliquiddramatically, which in turnmade the aggregate act as aliquid. Known as“liquefaction,” this processtransformedtheproteincubesfrom a steady solid into a
flowingsludge.Stored in a compartment
thatoriginallyhadnoleftoverspace, the now-compressedsludgehadroomtoslosh.Theshimmyalsocausedan
imbalanced load, forcing thesludge toward theedgeof itscompartment. This shift inweight only aggravated thelarger problem, and theshimmygrewstronger.
•••
“SHIMMY’S GETTING violent,”reported the ascent flightdirector.“Howviolent?”Mitchsaid.“More than we like,” he
said. “But the accelerometerscaught it and calculated thenew center of mass. Theguidance computer isadjusting the engines’ thrusts
to counteract. We’re stillgood.”“Keep me posted,” Mitch
said.“Thirteen seconds till
staging.”The unexpected weight
shifthadnot spelleddisaster.All systems were designedforworst-casescenarios;eachdid its job admirably. Theship continued toward orbit
with only a minor courseadjustment, implementedautomatically bysophisticatedsoftware.The first stage depleted its
fuel, and the booster coastedforafractionofasecondasitjettisoned stage clamps viaexplosive bolts. The now-empty stage fell away fromthe craft as the second-stageenginespreparedtoignite.The brutal forces had
disappeared. The proteinsludge floated free in thecontainer.Giventwoseconds,it would have re-expandedand solidified. But it wasgivenonlyaquartersecond.As the second stage fired,
the craft experienced asuddenjoltofimmenseforce.No longer contending withthe deadweight of the firststage, the acceleration wasprofound. The three hundred
kilogramsofsludgeslammedintothebackofitscontainer.The point of impact was attheedgeofIris,nowherenearwherethemasswasexpectedtobe.Though Iris was held in
place by five large bolts, theforcewasdirectedentirely toa single one. The bolt wasdesigned to withstandimmense forces; if necessaryto carry the entire weight of
the payload. But it was notdesigned to sustain a suddenimpact from a loose three-hundred-kilogrammass.The bolt sheared. The
burdenwasthenshiftedtotheremaining four bolts. Theforceful impact havingpassed, their work wasconsiderably easier than thatoftheirfallencomrade.Had the pad crew been
given time to do normal
inspections, theywould havenoticed the minor defect inoneofthebolts.Adefectthatslightly weakened it, thoughitwould not cause failure ona normal mission. Still, theywould have swapped it outwithaperfectreplacement.The off-center load
presentedunequalforcetothefour remaining bolts, thedefective one bearing thebrunt of it. Soon, it failed as
well. From there, the otherthree failed in rapidsuccession.Iris slipped from its
supports in the aeroshell,slammingintothehull.

filling out the form: makingthe launch date and flightpath clear, while doing
everything possible to“concealstatesecrets.”He snorted at the last

pinched his chin. Pacing, hesaid,“WecanreallysendtheTaiyangShentoMars?”“No, sir,” said Zhu Tao.
“It’s far too heavy. Themassiveheatshieldingmakesit the heaviest unmannedprobewe’veeverbuilt.That’swhy theboosterhad tobesopowerful. But a lighter
payload could be sent all thewaytoMars.”“Howmuchmasscouldwe
send?”GuoMingasked.“Nine hundred and forty-
onekilograms,sir.”“Hmm,”GuoMingsaid,“I
bet NASA could work withthat limitation. Why haven’ttheyapproachedus?”“Because they don’t
know,” Zhu Tao said. “All
our booster technology isclassified information. TheMinistry of State Securityeven spreads disinformationaboutourcapabilities.Thisisforobviousreasons.”“So they don’t know we
can help them,” Guo Mingsaid. “If we decide not tohelp, no one will know wecouldhave.”“Correct,sir.”
“For thesakeofargument,let’s saywe decided to help.Whatthen?”“Time would be the
enemy, sir,” Zhu Taoanswered. “Based on travelduration and the suppliestheirastronauthasremaining,anysuchprobewouldhavetobe launched within a month.Even then he would starve alittle.”“That’s right around when
weplannedtolaunchTaiyangShen.”“Yes, sir.But it took them
twomonths tobuild Iris,anditwassorusheditfailed.”“That’s their problem,”
Guo Ming said. “Our endwould be providing thebooster. We’d launch fromJiuquan; we can’t ship aneight-hundred-ton rocket toFlorida.”
“Any agreement wouldhinge on the Americansreimbursing us for thebooster,”ZhuTao said, “andthe State Council wouldlikely want political favorsfromtheUSgovernment.”“Reimbursement would be
pointless,” Guo Ming said.“This was an expensiveproject,andtheStateCouncilgrumbledaboutitallalong.Iftheyhadabulkpayoutforits
value, they’d just keep it.We’d never get to buildanotherone.”He clasped his hands
behind his back. “And theAmerican people may besentimental, but theirgovernment is not. The USStateDepartmentwon’t tradeanythingmajorforoneman’slife.”“So it’s hopeless?” asked
ZhuTao.
“Nothopeless,”GuoMingcorrected. “Just hard. If thisbecomes a negotiation bydiplomats, it will never beresolved. We need to keepthis among scientists. Spaceagency to space agency. I’llget a translator and callNASA’s administrator.We’llwork out an agreement, thenpresentit toourgovernmentsasafaitaccompli.”“Butwhat can they do for
us?” Zhu Tao asked. “We’dbe giving up a booster andeffectivelycancelingTaiyangShen.”GuoMingsmiled.“They’ll
give us something we can’tgetwithoutthem.”“Andthatis?”“They’ll put a Chinese
astronautonMars.”Zhu Tao stood. “Of
course.” He smiled. “The
Ares5crewhasn’tevenbeenselectedyet.We’llinsistonacrewman.Onewegettopickand train.NASAand theUSState Department wouldsurely accept that. But willourStateCouncil?”Guo Ming smiled wryly.
“Publicly rescue theAmericans? Put a Chineseastronaut onMars?Have theworld see China as equal tothe US in space? The State

“WHAT THE fuck is ‘ProjectElrond’?”Annieasked.“I had to make something

“Oneofourastrodynamicists,RichPurnell,hasfoundawayto getHermes back toMars.The course he came up withwould give Hermes a MarsflybyonSol549.”Silence.“You shittin’ us?” Annie

hishead.“Wow…549.That’s
thirty-fivesolsbeforeWatneyrunsoutof food.Thatwouldsolveeverything.”Teddy leaned forward.
“Run us through it, Venkat.Whatwoulditentail?”“Well,” Venkat began, “if
they did this ‘Rich PurnellManeuver,’ they’d startaccelerating right away, topreserve their velocity andgain even more. Theywouldn’t intercept Earth at
all, but would come closeenoughtouseagravityassistto adjust course.Around thattime, they’d pick up aresupply probe withprovisions for the extendedtrip.“Afterthat,they’dbeonan
accelerating orbit towardMars, arriving on Sol 549.LikeIsaid,it’saMaryflyby.This isn’t anything like anormalAresmission.They’ll
be going too fast to fall intoorbit. The rest of themaneuver takes themback toEarth. They’d be home twohundredandelevendaysaftertheflyby.”“What good is a flyby?”
Bruce asked. “They don’thave anyway to getWatneyoffthesurface.”“Yeah…,” Venkat said.
“Nowfortheunpleasantpart:Watneywouldhave toget to
theAres4MAV.”“Schiaparelli!?” Mitch
gaped. “That’s thirty-twohundredkilometersaway!”“Three thousand, two
hundred, and thirty-fivekilometers to be exact,”Venkat said. “It’s not out ofthe question. He drove toPathfinder’s landing site andback. That’s over fifteenhundredkilometers.”
“Thatwasover flat, desertterrain,” Bruce chimed in,“but the trip to Schiaparelli—”“Suffice it to say,”Venkat
interrupted,“itwouldbeverydifficult and dangerous. Butwe have a lot of cleverscientiststohelphimtrickoutthe rover. Also there wouldbeMAVmodifications.”“What’s wrong with the
MAV?”Mitchasked.
“It’sdesignedtogettolowMars orbit,” Venkatexplained. “But Hermeswould be on a flyby, so theMAV would have to escapeMars gravity entirely tointercept.”“How?”Mitchasked.“It’dhavetoloseweight…
a lot of weight. I can getroomsfullofpeopleworkingon these problems, if wedecidetodothis.”
“Earlier,”Teddysaid,“youmentionedasupplyprobeforHermes. We have thatcapability?”“Yes, with the Taiyang

“It should be CommanderLewis’scall,”Mitchsaid.“Pointlesstoevenaskher,”

“You guys have done endruns around the crew everytime something goes wrong.You didn’t tell themWatneywas still alive; now you’renottellingthemthere’sawaytosavehim.”“Wealreadyhaveawayto

said.“You’veexpressedyouropinion, and we’ve heard it.Let’smoveon.”HeturnedtoVenkat. “Can Hermesfunctionforfivehundredandthirty-three days beyond thescheduledmissionend?”“It should,” Venkat said.
“The crew may have to fixthings here and there, butthey’re well trained.
Remember, Hermes wasmade to do all five Aresmissions. It’s only halfwaythrough its designed lifespan.”“It’s the most expensive
thingeverbuilt,”Teddysaid.“Wecan’tmakeanotherone.Ifsomethingwentwrong,thecrewwoulddie,andtheAresProgramwiththem.”“Losingthecrewwouldbe

we wouldn’t lose Hermes.We can remotely operate it.Solongasthereactorandionengines continued to work,wecouldbringitback.”“Space travel is

“This is absolutely adiscussion about what’ssafest. And about howmany
lives are at stake.Both plansare risky, but resupplyingWatney only risks one lifewhile the Rich PurnellManeuverriskssix.”“Consider degree of risk,
Teddy,” Venkat said. “Mitchis right. The crash-lander ishigh-risk.ItcouldmissMars,it could reenter wrong andburn up, it could crash toohard and destroy the food…We estimate a thirty percent
chanceofsuccess.”“A near-Earth rendezvous
with Hermes is moredoable?”Teddyasked.“Much more doable,”
Venkat confirmed. “Withsub-second transmissiondelays, we can control theprobe directly from Earthratherthanrelyonautomatedsystems. When the timecomes to dock, MajorMartinezcanpilotitremotely

“The window for startingthe maneuver ends in thirty-ninehours.”“All right,” Teddy said.

Well…not right away. Istill have to do theaforementioned shitload ofwork.MytriptoPathfinderwasa
quick jaunt compared to theepic journey that’s comingup. I got away with a lot ofshortcuts because I only hadtosurviveeighteensols.Thistime,thingsaredifferent.I averaged 80 kilometers
per sol on my way to
Pathfinder. If I do that welltowardSchiaparelli,thetrip’lltakefortysols.Callitfiftytobesafe.But there’smore to it than
just travel. Once I get there,I’ll need to set up camp anddo a bunch of MAVmodifications. NASAestimates they’ll take thirtysols, forty-five to be safe.Between the trip and theMAV mods, that’s ninety-
five sols.Call itonehundredbecause ninety-five cries outtobeapproximated.So I’ll need to survive
away from the Hab for ahundredsols.“Whatabout theMAV?” I
hear you ask (in my feveredimagination). “Won’t it havesomesupplies?Airandwaterattheveryleast?”Nope.It’sgotdick-all.
It does have air tanks, butthey’re empty. An AresmissionneedslotsofO2,N2,andwateranyway.Whysendmore with the MAV? Easierto have the crew top off theMAV from the Hab.Fortunately for mycrewmates, the mission planhad Martinez fill the MAVtanksonSol1.TheflybyisonSol549,so
I’llneedtoleaveby449.That
givesme 257 sols to getmyassingear.Seems like a long time,
doesn’tit?In that time, I need to
modify the rover tocarry the“BigThree”: theatmosphericregulator,theoxygenator,andthewaterreclaimer.All threeneed to be in the pressurizedarea, but the rover isn’t bigenough.All three need to berunning at all times, but the

Big Three in and use Habcanvas to loosely cover thehole. It’ll balloonoutwhen Ipressurize the rover, but it’llhold. How will I cut a bigchunk out of a rover’s hull?I’ll let my lovely assistantVenkat Kapoor explainfurther:

I’ll be playing with high-voltage power tomorrow.Can’timagineanythinggoingwrongwiththat!
LOGENTRY:SOL193
Imanaged to not kill myselftoday, even though I wasworking with high voltage.
Well, it’s not as exciting asall that. I disconnected thelinefirst.As instructed, I turned a
rover charging cable into adrill power source. Gettingthevoltagerightwasasimplematter of adding resistors,whichmy electronics kit hasinabundance.I had to make my own
nine-amp breaker. I strungthree three-amp breakers in

Prettymuch the same thing IdidwithPathfinder.Takeoutthebatteryandreplaceitwitha power line from the Hab.But this time it was a loteasier.Pathfinder was too big to
fit through any of my
airlocks,soIhadtodoalltherewiring outside. Ever doneelectronics while wearing aspace suit? Pain in the ass. Ieven had to make aworkbench out of MAVlandingstruts,remember?Anyway,thedrillfitinthe

Also,unlikemyPathfinderhatchet job, I had the fullschematics of the drill. Iremoved the battery andattachedapowerlinewhereitused to be. Then, taking thedrillanditsnewcordoutside,Iconnectedittothemodifiedroverchargerandfireditup.Worked like a charm!The

The rovers are made tointerlock so one can tow the

battery long ago; it had noabilitytomoveunderitsownpower. So I hitched it up to
my awesomely modifiedrover and towed it intoplacenearPathfinder.Venkat told me to “draw”
theshapeIplantocut,butheneglected to mention how.It’s not like I have aSharpiethat can work out on thesurface. So I vandalizedMartinez’sbed.The cots are basically
hammocks. Lightweightstring woven loosely into

and took the string outside,thentapedittothetrailerhullalong the path I planned tocut.Yes, of course duct tapeworksinanear-vacuum.Ducttape works anywhere. Ducttape is magic and should beworshiped.
I can see what NASA hasin mind. The rear of thetrailer has an airlock thatwe’renotgoingtomesswith.Thecutisjustaheadofitandwill leaveplentyofspacefortheBigThreetostand.Ihaveno ideahowNASA

shesaid.[12:25]JPL:Seriously,Mark?
Seriously?
First, I depressurized thetrailer. Call me crazy, but Ididn’t want the drillexplosively launched at myface.Then I had to pick
somewhere tostart. I thoughtit’d be easiest to start on theside.Iwaswrong.The roofwould have been
better. The sidewas a hasslebecauseIhadtoholdthedrillparallel to the ground. This
isn’t your dad’s Black &Decker we’re talking about.It’s a meter long and onlysafetoholdbythehandles.Gettingittobitewasnasty.
I pressed it against the hulland turned it on, but itwandered all over the place.So I got my trusty hammerand screwdriver.With a fewtaps, I made a small chip inthecarboncomposite.Thatgavethebitaplaceto
seat, so I could keep drillingin one place. As NASApredicted, it took about twoand a halfminutes to get allthewaythrough.I followed the same
procedureforthesecondholeand it went much smoother.Afterthethirdhole,thedrill’soverheatlightcameon.The poor drill wasn’t
designed to operateconstantly for so long.
Fortunately, it sensed theoverheatandwarnedme.SoIleaned it against theworkbenchforafewminutes,and it cooled down. OnethingyoucansayaboutMars:It’s really cold. The thinatmosphere doesn’t conductheat very well, but it coolseverything,eventually.I had already removed the
drill’s cowling (the powercord needed a way in). A
pleasantsideeffectisthedrillcoolsevenfaster.ThoughI’llhave to clean it thoroughlyevery few hours as dustaccumulates.By 17:00, when the sun
began to set, I had drilledseventy-five holes. A goodstart, but there’s still tons todo. Eventually (probablytomorrow) I’ll have to startdrilling holes that I can’treach from the ground. For
that I’ll need something tostandon.I can’t use my
“workbench.” It’s gotPathfinder on it, and the lastthingI’mgoingtodoismesswith that. But I’ve got threemore MAV landing struts.I’msureIcanmakearamporsomething.Anyway,that’sallstufffor

Awww yeah. That’s right.I’m either getting rescued onSol 549 or I’m dying. Thatmeans I have thirty-five solsof extra food. I can indulgeonceinawhile.
LOGENTRY:SOL194
I average a hole every 3.5minutes. That includes theoccasional breather to let thedrillcooloff.
I learned this by spendingall damn day drilling. Aftereighthoursofdull,physicallyintensework,Ihad137holestoshowforit.It turned out to be easy to
deal with places I couldn’treach.Ididn’tneedtomodifyalandingstrutafterall.I justhadtogetsomethingtostandon. I used a geologicalsamplecontainer(alsoknownas“abox”).
Before I was in contactwith NASA, I would haveworked more than eighthours. I can stay out for tenbefore even dipping into“emergency” air. ButNASA’sgot a lot ofnervousNellies who don’t want meoutlongerthanspec.With today’s work, I’m
about one-fourth of the waythrough the whole cut. Atleast, one-fourth of the way
throughthedrilling.ThenI’llhave 759 little chunks tochisel out. And I’m not surehowwellcarboncompositeisgoing to take to that. ButNASA’ll do it a thousandtimes back on Earth and tellme the best way to get itdone.Anyway, at this rate, it’ll
take four more sols of(boring-ass) work to finishthedrilling.
I’ve actually exhaustedLewis’s supply of shittyseventies TV. And I’ve readall of Johanssen’s mysterybooks.I’ve already rifled through
othercrewmates’stufftofindentertainment. But all ofVogel’s stuff is in German,Beck brought nothing butmedical journals, andMartinez didn’t bringanything.
I got really bored, so Idecidedtopickathemesong!Something appropriate.
And naturally, it should besomething from Lewis’sgodawful seventiescollection. It wouldn’t berightanyotherway.There are plenty of great
candidates: “Life on Mars?”by David Bowie, “RocketMan” by Elton John, “AloneAgain(Naturally)”byGilbert
O’Sullivan.But I settled on “Stayin’

The Hab isn’t the samewithoutthem.There’s still soil

Ifuckedup.I fucked up big-time. I
made a mistake that mightkillme.
I started my EVA around08:45, same as always. I gotmy hammer and screwdriverand started chipping thetrailer’shull.It’sapainintheass to make a chip beforeeach drilling, so I make alltheday’schipsinasinglego.After chipping out 150

Back in theHab, Ienjoyedanice lunch and played somechessagainstthecomputer(itkicked my ass). Then backout for the day’s secondEVA.
At 13:30 my ruinationoccurred, though I didn’trealizeitatthetime.Theworstmoments in life

TheinternalelectronicsforPathfinder includedagroundlead to the hull. This way itcould not build up a staticcharge in Martian weatherconditions (no water andfrequent sandblasting canmake impressive staticcharge).The hull sat on Panel A,
one of four sides of thetetrahedron which broughtPathfindertoMars.Theother
three sides are still in AresValliswhereIleftthem.Between Panel A and the
workbench were the MylarballoonsPathfinder had usedto tumble-land. I hadshredded many of them totransport it, but a lot ofmaterial remained—enoughto reach around PanelA andbe in contactwith the hull. Ishouldmention thatMylar isconductive.
At13:30,I leanedthedrillagainst the workbench. Thedrill’s cowling was off tomake room for the powerline.Theworkbenchismetal.If thedrill leanedagainst theworkbenchjustright,itcouldmake a metal-to-metalconnection.And that’s exactly what

I’m not doomed.Thingswilljustbeharderthanplanned.Ihave all I need to survive.And Hermes is still on theway.IspelledoutaMorsecode

stoppedallworkonit.Idon’t
want to continue without aplan. I’m sureNASAhadallkindsofideas,butnowIhaveto come up with one on myown.As I mentioned, the Big
Three(atmosphericregulator,oxygenator, and waterreclaimer) are criticalcomponents.Iworkedaroundthem for my trip toPathfinder.IusedCO2 filtersto regulate the atmosphere,
and brought enough oxygenandwater for thewhole trip.That won’t work this time. IneedtheBigThree.Problemis, theysoakupa
lotofpower,andtheyhavetorun all day long. The roverbatteries have 18 kilowatt-hours of juice. Theoxygenator alone uses 44.1kilowatt-hours per sol. Seemyproblem?You know what?
“Kilowatt-hours per sol” is apain in the ass to say. I’mgonnainventanewscientificunitname.Onekilowatt-hourper sol is…it can beanything…um…I suck atthis…I’ll call it a “pirate-ninja.”All told, the Big Three
need 69.2 pirate-ninjas, mostof that going to theoxygenator and theatmospheric regulator. (The
water reclaimer only needs3.6ofthat.)There’llbecutbacks.The easiest cutback is the
water reclaimer. I have 620liters of water (I had a lotmore before the Hab blewup).Ineedonlythreelitersofwater per sol, so my supplywill last 206 sols. There’sonly100solsafterIleaveandbefore I’m picked up (or dieintheattempt).
Conclusion: I don’t needthewaterreclaimeratall.I’lldrinkasneededanddumpmywaste outdoors. Yeah, that’sright, Mars, I’m gonna pissand shit on you. That’swhatyou get for trying to kill meallthetime.There. I saved myself 3.6
pirate-ninjas.
LOGENTRY:SOL198
I’vehadabreakthroughwiththeoxygenator!I spent most of the day
looking at the specs. It heatsCO2 to 900°C, then passes itover a zirconia electrolysiscelltoyankthecarbonatomsoff. Heating the gas is whattakes most of the energy.Why is that important?BecauseI’mjustoneguyandtheoxygenatorwasmade forsix.One-sixth thequantityof
CO2 means one-sixth theenergytoheatit.Thespecsaysitdraws44.1
pirate-ninjas,butall thistimeit’s only been using 7.35because of the reduced load.Now we’re gettingsomewhere!Then there’s the matter of
the atmospheric regulator.Theregulatorsamplestheair,figuresoutwhat’swrongwith
it, and corrects the problem.ToomuchCO2? Take it out.Not enough O2? Add some.Without it, the oxygenator isworthless. TheCO2 needs tobe separated in order to beprocessed.The regulator analyzes the
air with spectroscopy, thenseparates the gasses bysupercooling them. Differentelements turn to liquid at
different temperatures. OnEarth,supercoolingthismuchair would take ridiculousamounts of energy. But (asI’m acutely aware) this isn’tEarth.Here on Mars,
supercooling is done bypumping air to a componentoutside the Hab. The airquickly cools to the outdoortemperature, which rangesfrom −150°C to 0°C. When
it’s warm, additionalrefrigerationisused,butcolddayscanturnairtoliquidforfree. The real energy costcomes from heating it backup.IfitcamebacktotheHabunheated,I’dfreezetodeath.“But wait!” You’re
thinking,“Mars’satmosphereisn’t liquid. Why does theHab’saircondense?”The Hab’s atmosphere is
over100timesasdense,soit
turnstoliquidatmuchhighertemperatures. The regulatorgets the best of bothworlds.Literally. Side note: Mars’satmospheredoes condense atthepoles.Infact, itsolidifiesintodryice.Problem: The regulator
takes21.5pirate-ninjas.Evenadding some of the Hab’spower cells would barelypowertheregulatorforasol,let alone give me enough
juicetodrive.Morethinkingisrequired.
LOGENTRY:SOL199
I’ve got it. I know how topower the oxygenator andatmosphericregulator.The problem with small
pressure vessels is CO2toxicity.Youcanhavealltheoxygenintheworld,butoncetheCO2getsabove1percent,
you’ll start togetdrowsy.At2 percent, it’s like beingdrunk.At5percent, it’shardto stay conscious. Eightpercent will eventually killyou.Stayingaliveisn’taboutoxygen, it’s about getting ridofCO2.That means I need the
regulator. But I don’t needtheoxygenatorall the time. Ijust need to get CO2 out of
the air and back-fill withoxygen. I have 50 liters ofliquid oxygen in two 25-litertankshere in theHab.That’s50,000litersingaseousform,enough to last 85 days. Notenough to seeme through torescue,butahellofalot.The regulator can separate
theCO2andstoreitinatank,and it can addoxygen tomyair frommyoxygen tanks asneeded. When I run low on
oxygen, Icancampout foradayanduseallmy power torun the oxygenator on thestored CO2. That way, theoxygenator’s powerconsumption doesn’t eat upmydrivingjuice.SoI’llruntheregulatorall
the time, but only run theoxygenatorondaysIdedicatetousingit.Now, on to the next
problem. After the regulatorfreezes the CO2 out, theoxygen and nitrogen are stillgasses, but they’re −75°C. Ifthe regulator fed thatback tomy air without reheating it,I’d be a Popsicle withinhours.Mostoftheregulator’spower goes to heating thereturn air so that doesn’thappen.But I have a betterway to
heat it up. SomethingNASA
wouldn’t consider on theirmosthomicidalday.TheRTG!Yes, the RTG. You may
rememberitfrommyexcitingtrip to Pathfinder. A lovelylump of plutonium soradioactive it gives off 1500wattsofheat,whichitusestoharvest 100 watts ofelectricity. So what happensto the other 1400 watts? Itgetsradiatedoutasheat.
OnthetriptoPathfinder,Ihad to actually removeinsulation from the rover tovent excess heat from thedamnthing.I’llbetapingthatback in place because I’llneedthatheattowarmupthereturnairfromtheregulator.I ran the numbers. The

as keeping the rover areasonabletemperature.To test, I shut down the
heaters in the regulator andnoteditspowerconsumption.Afterafewminutes,I turnedthem right back on again.Jesus Christ that return airwascold.ButIgotthedataIwanted.Withheating, theregulator

pirate-ninja. That’s right,almost all of the power wasgoingtoheat.As with most of life’s
problems, this one can besolved by a box of pureradiation.I spent the rest of the day
double-checkingmynumbersand runningmore tests. It allchecksout.Icandothis.

Ihauledrockstoday.I needed to know what
kind of power efficiency therover/trailer will get. On theway to Pathfinder, I got 80kilometers from 18 kilowatt-hours.Thistime,theloadwillbealotheavier.I’llbetowingthe trailer and all the othershit.Ibackedtheroveruptothe
trailer and attached the towclamps.Easyenough.
The trailer has beendepressurized for some timenow (there’s a couple ofhundredlittleholesinit,afterall), so I openedboth airlockdoors to have a straight shotattheinterior.ThenIthrewabunchofrocksin.I had to guess at the
weight.TheheaviestthingI’llbring with me is the water.620 kilograms’ worth. Myfreeze-driedpotatoeswilladd
another 200 kilograms. I’llprobably have more solarcells than before, andmaybea battery from the Hab. Plustheatmosphericregulatorandoxygenator,ofcourse.Ratherthanweighallthatshit,Itooka guess and called it 1200kilograms.Halfacubicmeterofbasalt
weighs about that much(more or less). After twohours of brutal labor, during
whichIwhineda lot, Igot itallloadedin.Then, with both batteries
fully charged, I drove circlesaroundtheHabuntilIdrainedthemboth.Withablisteringtopspeed
of25kph, it’snot anaction-packed thrill ride. But I wasimpressed it could maintainthat speed with all the extraweight. The rover hasspectaculartorque.
Butphysicallawisapushylittle shit, and it exactedrevenge for the additionalweight. I only got 57kilometersbeforeIwasoutofjuice.Thatwas57kilometerson
level ground, without havingtopowertheregulator(whichwon’t take much with theheater off). Call it 50kilometersperdaytobesafe.At that rate itwould take 64
daystogettoSchiaparelli.But that’s just the travel
time.Every now and then, I’ll
need to break for a day andlet theoxygenatoruseall thepower. How often? After abunch of math I worked outthat my 18-pirate-ninjabudget can power theoxygenator enough to makeabout2.5solsofO2.I’dhave
tostopeverytwotothreesolsto reclaimoxygen.Mysixty-four-sol trip would becomeninety-two!That’s too long. I’ll tear
myownheadoff if Ihavetoliveintheroverthatlong.Anyway, I’m exhausted
from lifting rocks andwhiningabout liftingrocks. Ithink I pulled something inmy back.Gonna take it easytherestoftoday.
LOGENTRY:SOL201
Yeah, I definitely pulledsomething in my back. Iwokeupinagony.So I took a break from
rover planning. Instead, Ispent the day taking drugsandplayingwithradiation.First, I loaded up on
Vicodinformyback.HoorayforBeck’smedicalsupplies!Then I drove out to the
RTG.ItwasrightwhereIleftit, in a hole four kilometersaway. Only an idiot wouldkeep that thingnear theHab.Soanyway, Ibrought itbacktotheHab.Either it’ll kill me or it
won’t. A lot of work wentinto making sure it doesn’tbreak. If I can’t trustNASA,whocanItrust?(FornowI’llforget that NASA told us toburyitfaraway.)
Istoreditontheroofoftherover for the trip back. Thatpuppyreallyspewsheat.Ihavesomeflexibleplastic
tubing intended for minorwaterreclaimerrepairs.Afterbringing the RTG into theHab, I very carefully gluedsome tubing around the heatbaffles.Using a funnelmadefrom a piece of paper, I ranwater through the tubing,letting it drain into a sample
container.Sure enough, the water
heatedup.That’snotreallyasurprise, but it’s nice to seethermodynamics being wellbehaved.There’sonetrickybit:The
atmosphericregulatordoesn’trun constantly. The freeze-separation speed isdrivenbythe weather outside. So thereturning frigid air doesn’tcome as a steady flow. And
theRTGgeneratesaconstant,predictable heat. It can’t“rampup”itsoutput.So I’ll heatwaterwith the
RTG to create a heatreservoir, then I’ll make thereturn air bubble through it.That way I don’t have toworry about when the aircomes in. And I won’t haveto deal with suddentemperature changes in therover.
When the Vicodin woreoff,my back hurt evenmorethan before. I’m going toneed to take it easy. I can’tjustpoppills forever.So I’mtaking a few days off fromheavy labor. To that end, Imadealittleinventionjustforme.…I took Johanssen’s cot and
cutout thehammock.Then IdrapedspareHabcanvasovertheframe,makingapitinside
the cot, with extra canvasaround the edges. Once Iweighed down the excesscanvas with rocks, I had awater-tightbathtub!It only took 100 liters to
filltheshallowtub.Then, I stole the pump
from the water reclaimer. (Ican go quite awhilewithoutthe water reclaimeroperating.) I hooked it up tomyRTGwaterheaterandput
both the input and outputlinesintothetub.Yes, I know this is
ridiculous,but Ihadn’thadabathsinceEarth,andmybackhurts. Besides, I’m going tospend100solswiththeRTGanyway. A few more won’thurt. That’s my bullshitrationalization and I’mstickingwithit.It took two hours to heat
the water to 37°C. Once it
did, I shut off the pump andgotin.Ohman!AllIcansayis“Ahhhhhh.”Whythehelldidn’tIthink

I spent the last weekrecovering from backproblems. The pain wasn’tbad, but there aren’t anychiropractors on Mars, so I
wasn’ttakingchances.I took hot baths twice a
day,layinmybunkalot,andwatched shitty seventies TV.I’ve already seen Lewis’sentire collection, but I didn’thavemuch else to do. I wasreducedtowatchingreruns.Igotalotofthinkingdone.I can make everything
better by having more solarpanels.The fourteenpanels Itook to Pathfinder provided
the18kilowatt-hoursthatthebatteries could store. Whentraveling,Istowedthepanelson the roof.The trailer givesme room to store anotherseven(halfofitsroofwillbemissing because of the holeI’mcuttinginit).This trip’s power needs
will be driven by theoxygenator. It all comesdown to how much power Ican give that greedy little
bastardinasinglesol.IwanttominimizehowoftenIhavedayswithnotravel.Themorejuice I can give theoxygenator, themoreoxygenit’ll liberate, and the longer Ican go between those “airsols.”Let’sgetgreedy.Let’s say
Icanfindahomeforfourteenmorepanelsinsteadofseven.Not sure how to do that, butlet’s say I can. That would
give me thirty-six pirate-ninjas to work with, whichwould net me five sols ofoxygen per air sol. I’d onlyhave to stop once per fivesols. That’s much morereasonable.Plus, if I can arrange
battery storage for the extrapower, I could drive 100kilometers per sol! Easiersaid than done, though. Thatextra 18 kilowatt-hours of
storage will be tough. I’llhavetotaketwooftheHab’s9-kilowatt-hourfuelcellsandload them onto the rover ortrailer. They aren’t like therover’s batteries; they’re notsmall or portable. They’relight enough, but they’repretty big. I may have toattach them to the outsidehull, and that would eat intomysolarcellstorage.One hundred kilometers
per sol is pretty optimistic.Butlet’ssayIcouldmake90kilometers per sol, stoppingevery fifth sol to reclaimoxygen.I’dgetthereinforty-five sols. That would besweet!In other news, it occurred
tomethatNASAisprobablyshitting bricks. They’rewatching me with satellitesand haven’t seen me comeout of the Hab for six days.
With my back better, it wastimetodropthemaline.I headed out for an EVA.
This time, beingvery carefulwhileluggingrocksaround,Ispelled out a Morse codemessage: “INJUREDBACK.BETTER NOW.CONTINUING ROVERMODS.”That was enough physical
labor for today. I don’twanttooverdoit.
ThinkI’llhaveabath.
LOGENTRY:SOL208
Today, it was time toexperimentwiththepanels.First,IputtheHabonlow-
power mode: no internallights, all nonessentialsystems offline, all internalheating suspended. I’d beoutside most of the dayanyway.
Then I detached twenty-eight panels from the solarfarmanddraggedthemtotherover. I spent four hoursstacking them this way andthat. The poor rover lookedlike the Beverly Hillbilliestruck.NothingIdidworked.The only way to get all
twenty-eight on the roofwastomakestackssohighthey’dfalloffthefirsttimeIturned.If I lashed them together,
they’d fall off as a unit. If Ifound a way to attach themperfectly to the rover, theroverwouldtip.Ididn’tevenbother to test. Itwasobviousbylooking,andIdidn’twanttobreakanything.I haven’t removed the

sevencells.Thatwouldworkfine; it’s just two rovers’worth of what I did for thetriptoPathfinder.Problem is I need that
opening.Theregulatorhastobeinthepressurizedareaandit’s too big to fit in theunmodified rover. Pluswhich, the oxygenator needsto be in a pressurized areawhile operating. I’ll onlyneed it every five sols, but
whatwould Idoon that sol?No,theholehastobethere.Asitis,I’llbeabletostow
twenty-one panels. I needhomes for the other seven.There’s only one place theycango: thesidesof theroverandtrailer.One of my earlier
modifications was“saddlebags”drapedover therover.Onesideheldtheextrabattery (stolen from what is
now the trailer), while theothersidewasfullofrocksascounterweight.I won’t need the bags this
time around. I can return thesecond battery to the trailerfromwhenceitcame.Infact,it’llsavemethehassleofthemid-drive EVA I had to doevery day to swap cables.When the rovers are linkedup, they share resources,includingelectricity.
I went ahead andreinstalled the trailer’sbattery.Ittookmetwohours,butit’soutofthewaynow.Iremoved the saddlebags andset them aside. Theymay behandy down the line. If I’velearned one thing from mystay at Club Mars, it’s thateverythingcanbeuseful.Ihad liberated thesidesof

Cold night last night. Thesolarcellswerestilldetachedfrom the farm, so I had toleave the Hab in low-powermode.Ididturntheheatbackon (I’mnot insane),but I setthe internal temperature to1°C to conserve power.Waking up to frigid weatherfelt surprisingly nostalgic.

I am smiling a great smile.The smile of a man whofuckedwithhiscaranddidn’tbreakit.I spent today removing
unnecessary crap from theroverandtrailer.Iwasprettydamnaggressiveaboutit,too.Space inside the pressurevessels is at a premium. Themore crap I clear out of therover,themorespacethereisforme.ThemorecrapIclearout of the trailer, the moresupplies Icanstore in it,andthelessIhavetostore in therover.Firstoff:Eachvehiclehad

wrong with the rover’scomputerenroute,I’llhaveaspare.The trailer had tons more
space now. It was time forexperimentation.The Hab has twelve 9-
kilowatt-hour batteries.They’re bulky and awkward.Over two meters tall, a halfmeter wide, and three-quarters of a meter thick.Making them bigger makes
them take less mass perkilowatt hour of storage.Yeah, it’s counterintuitive.But once NASA figured outtheycouldincreasevolumetodecrease mass, they were alloverit.Massistheexpensivepart about sending things toMars.Idetachedtwoofthem.As
long as I return them beforethe end of the day, thingsshould be fine. The Hab
mostly uses the batteries atnight.With both of the trailer’s

I’d never have gotten thembothin.The trailer’s battery is in
the undercarriage, but themainpowerlinerunsthroughthe pressure vessel, so I wasabletowiretheHabbatteriesdirectly in (no small feat inthedamnEVAsuit).A system check from the
rover showed I had done thewiringcorrectly.
This may all seem minor,but it’s awesome. It means Ican have twenty-nine solarcellsand36kilowatt-hoursofstorage.I’llbeable todomy100 kilometers per day afterall.Four days out of five,
anyway.

flexible sample container(“Ziploc bag”) and tried toseal the RTG in it. But theRTG has an irregular shape,and I couldn’t get all the airout of the bag. I can’t allowany air in there. Instead of
heatgoingtothewater,somewould get stored in the air,which could superheat andmeltthebag.Itriedabunchoftimes,but
there was always an airpocket I couldn’t get out. Iwas getting pretty frustrateduntil I rememberedIhaveanairlock.Suiting up, I went to
Airlock 2 and depressurizedto a full vacuum. I plopped
the RTG in the bag andclosed it. Perfect vacuumseal.Next came some testing. I
put the bagged RTG at thebottom of the container andfilled it with water. It holdstwenty liters, and the RTGquickly heated it. It wasgainingadegreeperminute.Ilet it go until it was a good40°C. Then I hooked up theregulator’s return air line to

The worst part of thePathfinder trip was beingtrapped in the rover. Ihad tolive in a cramped

Butthat’salotofcanvas.Istarted this mission with sixsquare meters and I’ve usedup most of that. Mostly onsealingthebreachfromwhentheHabblewup.GoddamnAirlock1.Anyway,mybedroomwill

Problem is (follow meclosely here, the science isprettycomplicated),ifIcutaholeintheHab,theairwon’tstayinsideanymore.I’ll have to depressurize
theHab, cut chunks out, andputitbacktogether(smaller).Ispent todayfiguringout theexact sizes and shapes ofcanvasI’llneed.Ineedtonotfuck this up, so I triple-checked everything. I even

I started the day with apotato.Iwasheditdownwithsome Martian coffee. That’smynamefor“hotwaterwithacaffeinepilldissolvedinit.”I ran out of real coffeemonthsago.My first order of business
wasacarefulinventoryoftheHab. I needed to root outanything that would have aproblem with losingatmospheric pressure. Of
course,everythingintheHabhad a crash course indepressurization a fewmonths back. But this timewould be controlled, and Imightaswelldoitright.The main thing is the
water. I lost 300 liters tosublimation when the Habblewup.Thistime,thatwon’thappen. I drained the waterreclaimer and sealed all thetanks.
Therestwasjustcollectingknickknacks and dumpingtheminAirlock3.AnythingIcouldthinkofthatdoesn’tdowell in a near-vacuum. Allthe pens, vitamin bottles(probably not necessary butI’m not taking chances),medicalsupplies,etc.Then I did a controlled
shutdown of the Hab. Thecritical components aredesigned to survive a
vacuum. Hab depress is oneofthemanyscenariosNASAaccounted for.Onesystematatime,Icleanlyshutthemalldown, ending with the maincomputeritself.I suited up and
depressurized the Hab. Lasttime, the canvas collapsedand made a mess ofeverything. That’s notsupposed to happen. Thedome of the Hab is mostly
supportedbyairpressure,butthere are flexible reinforcingpolesacrosstheinsidetoholdup the canvas. It’s how theHab was assembled in thefirstplace.I watched as the canvas
gently settled onto the poles.To confirm thedepressurization, I openedbothdoorsofAirlock2.IleftAirlock3alone.Itmaintainedpressure for its cargo of
randomcrap.ThenIcutshitup!I’m not a materials
engineer; my design for thebedroom isn’t elegant. It’sjustasix-meterperimeteranda ceiling. No, it won’t haveright angles and corners(pressure vessels don’t likethose). It’ll balloon out to amoreroundshape.Anyway, it means I only
needed to cut two big-assstrips of canvas. One for thewallsandonefortheceiling.After mangling the Hab, I
pulled the remaining canvasdown to the flooring andresealed it. Ever set up acamping tent? From theinside?While wearing a suitofarmor?Itwasapainintheass.I repressurized to one-

After two cups ofMartiancoffee, I woke up a little. Iwon’t be taking another oneof those pills. It’s not like Ihave to go to work in themorning.Anyway, as you can tell
fromhownotdead I am, theHab stayed sealed overnight.Thesealissolid.Uglyashell,butsolid.Today’s task was the
bedroom.
Assembling the bedroomwaswayeasierthanresealingtheHab.Because this time, Ididn’t have to wear an EVAsuit. I made the whole thinginsidetheHab.Whynot?It’sjust canvas. I can roll it upand take it out an airlockwhenI’mdone.First,Ididsomesurgeryon
the remaining pop-tent. Ineeded to keep the rover–airlock connector and
surrounding canvas. The restofthecanvashadtogo.Whyhack off most of the canvasonly to replace it with morecanvas?Seams.NASA is good at making
things. I am not. Thedangerous part of thisstructurewon’tbethecanvas.It’ll be the seams. And I getless total seam length by nottryingtousetheexistingpop-tentcanvas.
After hacking away mostof the remaining tent, I seal-stripped the two pop-tentfloorstogether.ThenIsealedthe new canvas pieces intoplace.It was so much easier
without the EVA suit on. Somucheasier!ThenIhadtotestit.Again,
Idid it in theHab. IbroughtanEVAsuitintothetentwithme and closed the mini-

Then I sat around andwaited. I breathed; the suitregulated the air. All waswell. I watched the suitreadouts carefully to see if ithad to replace any “lost” air.After an hour with nonoticeable change, I declaredthefirsttestasuccess.Irolledupthewholething

This presents a problem.UnlikeonmyPathfindertrip,I have to take vital lifesupport elements out of theHabifI’mgoingtodoarealdry run. When you take theatmospheric regulator andoxygenator out of the Hab,you’re left with…a tent. Abig round tent that can’tsupportlife.It’snotasriskyasitseems.
Asalways,thedangerouspart
about life support ismanaging carbon dioxide.Whentheairgetsto1percentCO2, you start gettingsymptoms of poisoning. So Ineed to keep the Hab’s mixbelowthat.TheHab’s internalvolume
is about 120,000 liters.Breathing normally, it wouldtake me over two days tobring the CO2 level up to 1
percent (and Iwouldn’t evenputadentintheO2level).Soit’ssafetomovetheregulatorand oxygenator over for awhile.Botharewaytoobigtofit
through the trailer airlock.Lucky for me, they came toMars with “some assemblyrequired.”Theywere toobigtosendwhole,sothey’reeasytodismantle.
Overseveraltrips,Imovedall of their chunks to thetrailer. I brought each chunkin through theairlock,oneatatime.Itwasapainintheassreassembling them inside, letme tell you. There’s barelyenough room for all the shitthetrailer’sgottohold.Therewasn’t much left for ourintrepidhero.ThenIgottheAREC.Itsat
outside the Hab like an AC

air to the AREC, then thereturn air needs to bubblethrough the heat reservoir.The regulator also needs a
pressure tank to contain theCO2itpullsfromtheair.Whengutting the trailer to
makeroom,Ileftonetankinplaceforthis.It’ssupposedtohold oxygen, but a tank’s atank. Thank God all the airlines and valves arestandardized across themission.That’snomistake.Itwas a deliberate decision tomakefieldrepairseasier.
Once I had the AREC inplace, I hooked theoxygenatorandregulatorintothe trailer’s power andwatchedthempowerup.Iranboth through full diagnosticstoconfirmtheywereworkingcorrectly. Then I shut downthe oxygenator. Remember,I’llonlyuse itonesoloutofeveryfive.I moved to the rover,
which meant I had to do an
annoying ten-meter EVA.From there, I monitored thelife support situation. It’sworth noting that I can’tmonitor the actual supportequipment from the rover(it’sall inthetrailer),buttherovercantellmeallabouttheair. Oxygen, CO2,temperature, humidity, etc.Everythingseemedokay.After getting back into the
EVA suit, I released a
canister of CO2 into therover’s air. I watched therovercomputerhaveashitfitwhenitsawtheCO2spiketolethallevels.Then,overtime,the levelsdropped tonormal.The regulator was doing itsjob.Goodboy!I left the equipment
running when I returned totheHab.It’llbeonitsownallnight and I’ll check it in the

Everything was fine. If Idon’tdriveit,asinglechargeofthebatteriescouldkeeptheregulator going for over amonth (with the heater off).It’s a pretty good safetymargin to have. If all hellbreaks loose on my trip, I’llhavetimetofixthings.I’llbelimited by oxygenconsumption rather thanCO2
removal,andIhaveplentyofoxygen.I decided it was a good
timetotestthebedroom.I got in the rover and
attached the bedroom to theouter airlock door from theinside. Like I mentionedbefore,thisistheonlywaytodo it. Then I turned it looseonanunsuspectingMars.As intended, the pressure
from the rover blasted thecanvas outward and inflatedit. After that, chaos. Thesudden pressure popped thebedroom like a balloon. Itquicklydeflated,leavingbothitselfand theroverdevoidofair. I was wearing my EVAsuit at the time; I’m not afuckingidiot.SoIgetto…LiveAnotherSol!(Starring

I’m getting pretty good at
this. Maybe when all this isover I could be a producttesterforMarsrovers.Things went well. I spent
five sols driving in circles; Iaveraged 93 kilometers persol.That’s a littlebetter thanI’dexpected.Theterrainhereis flat and smooth, so it’spretty much a best-casescenario. Once I’m going uphills and around boulders, itwon’tbenearlythatgood.
The bedroom is awesome.Large, spacious, andcomfortable. On the firstnight, I ran into a littleproblem with thetemperature. It was fuckingcold. The rover and trailerregulate their owntemperatures just fine, butthingsweren’t hot enough inthebedroom.Storyofmylife.The rover has an electric
heater that pushes air with asmall fan. I don’t use theheater itself for anythingbecausetheRTGprovidesalltheheatIneed,soIliberatedthe fan and wired it into apower line near the airlock.Once it had power, all I hadto do was point it at thebedroom.It’salow-techsolution,but
it worked. There’s plenty ofheat,thankstotheRTG.Ijust
neededtogetitevenlyspreadout.Foronce,entropywasonmyside.I’ve discovered that raw
potatoesaredisgusting.WhenI’m in the Hab, I cook mytaters using a smallmicrowave. I don’t haveanything like that in therover.IcouldeasilybringtheHab’s microwave into therover and wire it in, but theenergy required to cook ten
potatoesadaywouldactuallycutintomydrivingdistance.I fell into a routine pretty
quickly. In fact, it washauntingly familiar. I did itfortwenty-twomiserablesolson the Pathfinder trip. Butthis time, I had the bedroomand that makes all thedifference. Instead of beingcoopedupintherover,IhavemyownlittleHab.After waking up, I have a
potato for breakfast. Then, Ideflate thebedroomfromtheinside.It’skindoftricky,butIworkedouthow.First,IputonanEVAsuit.
ThenIclosetheinnerairlockdoor, leaving the outer door(which the bedroom isattached to) open. Thisisolatesthebedroom,withmein it, from the rest of therover. Then I tell the airlockto depressurize. It thinks it’s
just pumping the air out of asmall area, but it’s actuallydeflatingthewholebedroom.Once the pressure is gone,
I pull the canvas in and foldit. Then I detach it from theouter hatch and close theouter door. This is the mostcrampedpart.Ihavetosharethe airlock with the entirefolded-up bedroom while itrepressurizes. Once I havepressure again, I open the
inner door and more or lessfall into the rover. Then Istow the bedroom and goback to the airlock for anormalegresstoMars.It’s a complicated process,
but it detaches the bedroomwithout having todepressurize the rover cabin.Remember, the rover has allmy stuff that doesn’t playwellwithvacuum.The next step is to gather
upthesolarcellsIlaidoutthedaybeforeandstowthemonthe rover and trailer. Then Ido a quick check on thetrailer. I go in through itsairlock and basically take aquick look at all theequipment. I don’t even takeoffmyEVAsuit. I justwantto make sure nothing’sobviouslywrong.Then, back to the rover.
Once inside, I take off the
EVA suit and start driving. Idrive for almost four hours,andthenI’moutofpower.Once I park, it’s back into
theEVAsuitforme,andouttoMarsagain. I lay thesolarpanels out and get thebatteriescharging.ThenIsetupthebedroom.
Prettymuchthereverseofthesequence I use to stow it.Ultimately, it’s the airlockthat inflates it. In away, the
bedroom is just an extensionoftheairlock.Eventhoughit’spossible,I
don’t rapid-inflate thebedroom. I did that to test itbecause I wanted to findwhereit’llleak.Butit’snotagood idea. Rapid inflationputs a lot of shock andpressure on it. It wouldeventually rupture. I didn’tenjoy that time the Hablaunched me like a

All the components I didn’tsteal for the trip toSchiaparelli.I could have left them on.
It’s not like anyone wouldcare. But the originalprocedure for Sol 31 (whichwas supposed to be the lastday of the surface mission)was tocompletelyshutdownthe Hab and deflate it,becauseNASAdidn’twantabig tent full of combustible

Another uneventful sol.Tomorrow is an Air Day, sothis is kind of my Fridaynight.I’mabouthalfway through
Mawrth Vallis now. Just asI’dhoped,thegoinghasbeeneasy. No major elevationchanges. Hardly anyobstacles. Just smooth sandwithrockssmallerthanhalfameter.You may be wondering
howInavigate.WhenIwentto Pathfinder, I watchedPhobos transit the sky tofigure out the east-west axis.But Pathfinder was an easytrip compared to this, and Ihad plenty of landmarks tonavigateby.I can’t get away with that
thistime.My“map”(suchasit is) consists of satelliteimagesfar too low-resolutionto be of any use. I can only
see major landmarks, likecraters 50 kilometers across.They just never expectedmeto be out this far. The onlyreason I had high-res imagesof the Pathfinder region isbecause they were includedfor landing purposes; in caseMartinez had to land waylongofourtarget.So this time around, I
needed a reliable way to fixmypositiononMars.
Latitude and longitude.That’s the key. The first iseasy.AncientsailorsonEarthfigured that one out rightaway. Earth’s 23.5-degreeaxis points at Polaris. Marshas a tilt of just over 25degrees, so it’s pointed atDeneb.Making a sextant isn’t
hard.Allyouneedisatubetolook through, a string, aweight, and something with
degree markings. I mademineinunderanhour.So I go out every night
withahomemadesextantandsightDeneb.It’skindofsillyif you think about it. I’m inmy space suit on Mars andI’m navigating withsixteenth-century tools. Buthey,theywork.Longitude is a different
matter.OnEarth, the earliestway to work out longitude
required them to know theexacttime,thencompareittothe sun’s position in the sky.The hard part for them backthen was inventing a clockthat would work on a boat(pendulums don’t work onboats). All the top scientificminds of the age worked ontheproblem.Fortunately, I have
accurate clocks. There arefour computers in my
immediate line of sight rightnow.AndIhavePhobos.Because Phobos is
ridiculously close toMars, itorbits the planet in less thanone Martian day. It travelswest to east (unlike the sunand Deimos) and sets everyeleven hours. And naturally,itmovesinaverypredictablepattern.I spend thirteen hours
every sol just sitting around
while the solarpanelschargethe batteries. Phobos isguaranteedtosetatleastonceduring that time. I note thetime when it does. Then Iplug it intoanasty formula Iworked out and I know mylongitude.So working out longitude
requires Phobos to set, andworking out latitude requiresit to be night so I can sightDeneb. It’s not a very fast
system. But I only need itonce a day. I work out mylocation when I’m parked,andaccount for it in thenextday’s travel. It’s kind of asuccessive approximationthing.Sofar,Ithinkit’sbeenworking. But who knows? Icansee itnow:meholdingamap, scratching my head,trying to figure out how IendeduponVenus.

MawrthValliswasfunwhileit lasted. I’m inArabiaTerra
now.Ijustenteredtheedgeofit,
if my latitude and longitudecalculations are correct. Buteven without the math, it’spretty obvious the terrain ischanging.For the last two sols, I’ve
spent almost all my time onan incline, working my wayup the back wall of MawrthVallis. It was a gentle rise,but a constant one. I’m at a
much higher altitude now.Acidalia Planitia (where thelonelyHab ishangingout) is3000 meters below elevationzero,andArabiaTerrais500meters below. So I’ve goneuptwoandahalfkilometers.Want to know what
elevation zero means? OnEarth, it’s sea level.Obviously, that won’t workonMars.Solab-coatedgeeksgot together and decided
Mars’s elevation zero iswherever the air pressure is610.5 pascals. That’s about500 meters up from where Iamrightnow.Now things get tricky.

MyfifthAirDay, and things

Arabia Terra is certainlyrockierthanAcidaliaPlanitia,but nowhere near as bad asI’d feared. I’ve been able todriveovermostof the rocks,and around the ones that aretoo big. I have 1435

Well,Ifuckeditup.It was bound to happen
eventually. I navigated badlyand ended up at the ridge of
Marth Crater. Because it’s100 kilometers wide, I can’tseethewholething,soIdon’tknow where on the circle Iam.The ridge runs
perpendicular to thedirectionI was going. So I have nocluewhichway I should go.And I don’twant to take thelong way around if I canavoid it. Originally I wantedtogoaroundtothesouth,but

Oneofthemwillprobablybebetter than theother,because
it’ll be a shorter path aroundthecrater.I figured I should put at

IthinkIcanworkthisout.I’m on the very edge of a

It’llcometome.The storm is just dust in
the air; it’s not dangerous totherovers.Icanthinkofitas“percent power loss.” Ichecked yesterday’s powergeneration, and it was 97percent of optimal. So rightnow,it’sa3percentstorm.I need to make progress
and I need to regenerateoxygen. Those are my twomain goals. I use 20 percent
of my overall power toreclaim oxygen (when I stopforAirDays). If I end up inan 81 percent part of thestorm, I’ll be in real trouble.I’llrunoutofoxygenevenifIdedicateallavailablepowerto producing it. That’s thefatal scenario.But really, it’sfatalmuchearlier than that. IneedpowertomoveorI’llbestranded until the stormpasses or dissipates. That

the more I’ll have formovement.Withclearskies,Idedicate 80 percent of mytotal power towardmovement. I get 90kilometers per sol this way.So right now, at 3 percentloss, I’m getting 2.7kilometerslessthanIshould.It’s okay to lose some
driving distance per sol. I
have plenty of time, but Ican’t letmyself get too deepin the storm or I’ll never beabletogetout.Attheveryleast,Ineedto
travelfasterthanthestorm.IfI can go faster, I canmaneuver around it withoutbeingenveloped.SoIneedtofindouthowfastit’smoving.Icandothatbysittinghere
for a sol. I can comparetomorrow’s wattage to
today’s. All I have to do ismake sure to compare at thesame times of day. Then I’llknow how fast the storm ismoving, at least in terms ofpercentpowerloss.But I need to know the
shapeofthestorm,too.Dust storms are big. They
can be thousands ofkilometers across. Sowhen Iwork my way around it, I’llneed to know which way to
go. I’ll want to moveperpendicular to the storm’smovement, and in whateverdirectionhaslessstorm.Sohere’smyplan:Right now, I can go 86
kilometers (because Icouldn’t get a full batteryyesterday). Tomorrow, I’mgoing to leave a solar cellhere and drive 40 kilometersdue south. Then I’ll drop offanother solar cell and drive
another 40 kilometers duesouth. That’ll give me threepoints of reference across 80kilometers.The next day, I’ll go back
tocollectthecellsandgetthedata. By comparing thewattage at the same time ofday in those three locations,I’ll learn the shape of thestorm. If the storm is thickerto the south, I’ll go north toget around it. If it’s thicker
north,I’llgosouth.I’m hoping to go south.
Schiaparelli is southeast ofme.Goingnorthwouldaddalotoftimetomytotaltrip.There’soneslightproblem
with my plan: I don’t haveany way to “record” thewattage from an abandonedsolar cell. I can easily trackand log wattage with therover computer, but I needsomethingIcandropoffand
leavebehind.Ican’tjusttakereadings as I drive along. Ineed readings at the sametimeindifferentplaces.So I’m going to spend
today working on some madscience. I have to makesomething that can logwattage. Something I canleave behind with a singlesolarcell.Since I’m stuck here for
thedayanyway,I’llleavethe
solarcellsout. Imayaswellgetafullbatteryoutofit.
LOGENTRY:SOL477
It took all day yesterday andtoday,butIthinkI’mreadytomeasurethisstorm.I needed a way to log the
time of day and the wattageofeachsolarcell.Oneof thecells would be with me, butthe other two would be
droppedoffandleftfaraway.And the solution was theextra EVA suit I broughtalong.EVA suits have cameras
recording everything theysee. There’s one on the rightarm (or the left if theastronaut is left-handed) andanother above the faceplate.A time stamp is burned intothe lower left corner of theimage, just like on the shaky
home videos Dad used totake.My electronics kit has
several power meters. So Ifigured, why make my ownlogging system? I can justfilm the powermeter all daylong.So that’s what I set up.
When I packed for this roadtrip, Imade sure to bring allmykitsandtools.JustincaseI had to repair the rover en
route.First, I harvested the
cameras frommyspareEVAsuit. I had to be careful; Ididn’t want to ruin the suit.It’smyonlyspare.Iextractedthe cameras and the linesleading to their memorychips.I put a powermeter into a
small sample container, thenglued a camera to theunderside of the lid.When I
sealed up the container, thecamera was properlyrecording the readout of thepowermeter.For testing, I used rover
power. How will my loggerget power once I abandon iton the surface? It’ll beattached to a two-square-meter solar cell! That’llprovideplentyofpower.AndI put a small rechargeablebatteryinthecontainertotide
it over during nighttime(again, harvested from thespareEVAsuit).Thenextproblemwasheat,
or the lack thereof. As soonasI takethis thingoutof therover, it’llstartcoolingdownmighty fast. If it gets toocold, theelectronicswillstopworking.So I needed a heat source.
And my electronics kitprovided the answer:
resistors. Lots and lots ofthem. Resistors heat up. It’swhattheydo.Thecameraandthe powermeter only need atiny fraction of what a solarcell canmake. So the rest ofthe energy goes throughresistors.I made and tested two
“power loggers” andconfirmed that the imageswerebeingproperlyrecorded.Then I had an EVA. I
detached two of my solarcells and hooked them up tothepower loggers. I let themloghappily for an hour, thenbrought them back in tocheck the results. Theyworkedgreat.It’sgettingtowardnightfall
now.Tomorrowmorning,I’llleave one power loggerbehindandheadsouth.WhileIwasworking,Ileft
the oxygenator going (why
not?). So I’m all stocked uponO2andgoodtogo.Thesolarcellefficiencyfor
today was 92.5 percent.Compared to yesterday’s 97percent. This proves thestormismovingeasttowest,becausethedenserpartofthestorm was to the eastyesterday.So right now, the sunlight

valve apertures (triple-redundant ones, actually).NASA wanted to make surethe Hab could be refilledfromtheoutsideifnecessary.In the end, I’ll have the

I’ll evenbeable touse it as a workshop forwhateverMAVmodificationsIneedtodoonpartsthatcanfit through the trailer’sairlock.Of course, if the

shrunk at different rates.Some areas became hard asrockwhileothersremainedassoftastalc.While providing a small
average slope into thecrater,the ramp itself was ruggedandbitterlyuneven.On reaching Entrance

I had an EVA and thingsaren’t too bad. Mind you,they’renotgood.I trashed three solar cells.
They’re under the rover andcracked all to hell. Theymightstillbeable topissouta few watts, but I’m notholding out much hope.Luckily, I did come into thiswith one extra solar cell. Ineeded twenty-eight for my

over, but I wasn’t strongenough. I’ll need to rigsomething to get a leverageadvantage. Other than beingon its side, I don’t see anyrealproblems.
Well, that’s not true. Thetow hook is ruined beyondrepair.Halfofitrippedcleanoff. Fortunately, the traileralsohasatowhook,soIhaveaspare.Thetrailer’sinaprecarious

I started out pretty sore. Ihadtosleeponthewalloftherover. The bedroom won’twork when the airlock isfacingup.Ididgettousethebedroom, somewhat. I foldeditupanduseditasabed.Anyway, suffice it to say,
the wall of the rover wasn’tmade for sleeping on. Butafter a morning potato andVicodin, I was feeling muchbetter.
At first I figured my topprioritywasthetrailer.ThenIchanged my mind. Aftertaking a good look at it, Idecided I’d never be able toright it by myself. I’d needtherover.So today was focused on
gettingtheroverrighted.I brought all my tools
alongonthistrip,figuringI’dneed them for the MAVmodifications. And along
with them I brought cabling.OnceIgetsetupattheMAV,my solar cells and batterieswill be in a fixed position. Idon’twant tomovetheroveraroundeverytimeIuseadrillon the far side of theMAV.SoIbroughtall theelectricalcablingIcouldfit.Goodthing,too.Becauseit

roverand tiedoff thecord tothe roof-rackbaron thehighside. Now I had a long, tautline running perpendicular totherover.I walked to the middle of
the cord and pulled itlaterally. The leverageadvantage on the rover washuge. I only hoped it
wouldn’t break the drill bitbeforeittippedtherover.I backed away, pulling the

When I woke up thismorning, the trailer hadn’tpopped yet. So that was agoodstart.
The trailer was a biggerchallenge than the rover. Ionly had to tip the rover. I’dneed to completely flip thetrailer. That requires a lotmore force than yesterday’slittleleveragetrick.The first stepwas to drive
the rover to near the trailer.Thencamethedigging.OhGod,thedigging.The trailer was upside
down, with its nose pointeddownhill. I decided the bestway to right it was to takeadvantage of the slope androll the trailer over its nose.Basically to make it do asomersault to land on itswheels.I canmake thishappenby
tyingoffthecabletotherearofthetrailerandtowingwiththe rover. But if I tried thatwithout digging a hole first,
the trailer would just slidealong theground. I needed itto tipup. Ineededahole forthenosetofallinto.SoIdugahole.Aholeone
meter across, three meterswide, and onemeter deep. Ittookmefourmiserablehoursof hard labor, but I got itdone.I hopped in the rover and
drove it downhill, draggingthe trailer with me. As I’d
hoped, the trailer nosed intotheholeand tippedup.Fromthere, it fell onto its wheelswithahugeplumeofdust.Then I sat for a moment,
dumbstruck thatmyplanhadactuallyworked.And now I’m out of
daylightagain.Ican’twaittogetoutof thisdamnshadow.All I need is one day ofdriving toward theMAVandI’ll be away from the wall.
Butfornowit’sanotherearlynight.I’ll spend tonight without
the trailer tomanagemy lifesupport. It may be righted,but I have no idea if the shitinside still works. The roverstill has ample supplies forme.I’ll spend the rest of the
evening enjoying a potato.And by “enjoying” I mean“hatingsomuchIwanttokill

today. Not an easy task. It’s
prettycrampedinthere;Ihadto leavemyEVA suit in theairlock.The first thing I noticed
was that it was really hotinside. It took me a fewminutestoworkoutwhy.The atmospheric regulator
was still in perfect workingorder, but it had nothing todo.Without being connectedto the rover, itno longerhad
my CO2 production to dealwith. The atmosphere in thetrailer was perfect—whychangeanything?With no regulation
necessary, the air was notbeing pumped out to theAREC for freeze-separation.And thus it wasn’t comingbackinasaliquidinneedofheating.But remember, the RTG
gives off heat all the time.Youcan’tstopit.Sotheheatjust built up. Eventually,things reached a balancepoint where the heat bledthroughthehullasfastastheRTG could add it. If you’recurious, that balance pointwasasweltering41°C.I did a full diagnostic on
the regulator and theoxygenator,andI’mhappytoreport both are working
perfectly.TheRTG’swatertankwas
empty, which is no surprise.It has an open top, notintended to be turned upsidedown.Thefloorofthetrailerhas a lot of puddled waterthat tookmequiteawhile tosop up with my jumpsuit. Itoppedthetankoffwithsomemore water from a sealedcontainerthatI’dstoredinthetrailer earlier. Remember, I
need that water to havesomething for the returningair to bubble through. That’smyheatingsystem.Butallthingsconsidered,it
was good news. The criticalcomponentsareworkingfine,andbothvehiclesarebackontheirwheels.The hoses that connected
the rover and trailer weredesigned well, and releasedwithout breaking. I simply
snappedthembackintoplaceandthevehiclesweresharinglifesupportagain.Theoneremainingthingto

NASA has the MAVbroadcasting the Ares 3 Habhomingsignal.Whywouldn’tthey? Itmakes perfect sense.The MAV is a sleek,perfectly functional machine,ready to do what it’s told.And they have it pretendingto be theAres 3Hab, somyrover will see the signal andtellmewhereitis.That is an exceptionally

directedandaredesigned forline-of-sight communication.And there aren’t any sanddunes between it and Earthwhentheytalk.Somehow they messed
with things to make a radialsignal, howeverweak itmaybe.AndIheardit!My message for the day

of the booklet from hisbriefcase. “There were somegimmesrightoffthebat.ThedesignpresumesfivehundredkilogramsofMartiansoilandrock samples. Obviously wewon’t do that. Also, there’sjust one passenger instead ofsix. That saves five hundredkilogramswhenyouconsidertheir weight plus their suits

“We’re ditching all lifesupport. The tanks, pumps,heaters, air lines, CO2absorption system, even the
insulationontheinnersideofthe hull. We don’t need it.We’ll haveWatney wear hisEVAsuitforthewholetrip.”“Won’t that make it
awkward for him to use thecontrols?”Venkatasked.“Hewon’tbeusingthem,”
Bruce said. “Major Martinezwill pilot theMAV remotelyfrom Hermes. It’s alreadydesigned for remote piloting.Itwas remotely landed, after
all.”“What if something goes
wrong?”Venkatasked.“Martinez is the best
trainedpilot,”Brucesaid.“Ifthere is an emergency, he’sthe guy youwant controllingtheship.”“Hmm,” Venkat said
cautiously.“We’veneverhada manned ship controlledremotelybefore.Butokay,go
on.”“Since Watney won’t be
flying the ship,” Brucecontinued,“hewon’tneedthecontrols. We’ll ditch thecontrol panels and all thepoweranddatalinesthatleadtothem.”“Wow,” Venkat said.
“We’re really gutting thisthing.”“I’m just getting started,”
Brucesaid.“Thepowerneedswill be dramatically reducednowthatlifesupportisgone,so we’ll dump three of thefive batteries and theauxiliary power system. Theorbital maneuvering systemhas threeredundant thrusters.We’ll get rid of those. Also,the secondary and tertiarycommsystemscango.”“Wait,what?”Venkatsaid,
shocked. “You’re going to
have a remote-controlledascentwithnobackupcommsystems?”“Nopoint,”Brucesaid.“If
the comm system goes outduring ascent, the time ittakes to reacquirewillbe toolong to do any good. Thebackupsdon’thelpus.”“This is getting really
risky,Bruce.”Bruce sighed. “I know.
There’s just no other way.AndI’mnoteventothenastystuffyet.”Venkat rubbed his
forehead. “By all means, tellmethenastystuff.”“We’ll remove the nose
airlock, the windows, andHullPanelNineteen.”Venkat blinked. “You’re
taking the front of the shipoff?”
“Sure,” Bruce said. “Thenose airlock alone is fourhundred kilograms. Thewindows are pretty damnheavy, too. And they’reconnected by Hull PanelNineteen,somayaswelltakethat,too.”“So he’s going to launch
withabigholeinthefrontoftheship?”“We’ll have him cover it
withHabcanvas.”
“Habcanvas?Foralaunchtoorbit!?”Bruce shrugged. “The
hull’s mostly there to keeptheair in.Mars’satmosphereissothinyoudon’tneedalotof streamlining. By the timethe ship’s going fast enoughfor air resistance to matter,it’ll be high enough thatthere’s practically no air.We’verunallthesimulations.Shouldbegood.”
“You’re sending him tospaceunderatarp.”“Prettymuch,yeah.”“Like a hastily loaded
pickuptruck.”“Yeah.CanIgoon?”“Sure,can’twait.”“We’ll also have him
remove thebackpanelof thepressure vessel. It’s the onlyother panel he can removewith the toolsonhand.Also,
we’re getting rid of theauxiliary fuel pump. Sad tosee it go, but it weighs toomuch for its usefulness.Andwe’re nixing a Stage Oneengine.”“Anengine?”“Yeah. The Stage One
booster works fine if oneengine goes out. It’ll save usa huge amount of weight.Only during the Stage Oneascent, but still. Pretty good

I’m turningwater into rocketfuel.It’seasierthanyou’dthink.Separating hydrogen and
oxygenonlyrequiresacoupleof electrodes and somecurrent. The problem iscollecting the hydrogen. I
don’thaveanyequipmentforpulling hydrogen out of theair. The atmosphericregulator doesn’t even knowhow. The last time I had toget hydrogen out of the air(backwhen I turned theHabinto a bomb) I burned it toturn it into water. Obviouslythat would becounterproductive.But NASA thought
everything through and gave
me a process. First, Idisconnected the rover andtrailerfromeachother.Then,whilewearingmyEVAsuit,Idepressurized the trailer andback-filled it with pureoxygen at one-fourth of anatmosphere.Then I opened aplastic box full of water andputacoupleofelectrodes in.That’s why I needed theatmosphere. Without it, thewater would just boil
immediately and I’d behanging around in a steamyatmosphere.The electrolysis separated
the hydrogen and oxygenfrom each other. Now thetrailerwas full of evenmoreoxygen and also hydrogen.Prettydangerous,actually.Then I fired up the
atmosphericregulator.IknowIjustsaiditdoesn’trecognizehydrogen, but it does know
how to yank oxygen out oftheair.Ibrokeallthesafetiesand set it topull100percentof the oxygen out. After itwasdone,all thatwas left inthe trailer was hydrogen.That’swhyIstartedoutwithan atmosphere of pureoxygen, so the regulatorcouldseparateitlater.Then I cycled the rover’s
airlock with the inner dooropen. The airlock thought it
was evacuating itself, but itwas actually evacuating thewhole trailer. The air wasstoredintheairlock’sholdingtank.Andthereyouhaveit,atankofpurehydrogen.I carried the airlock’s
holdingtanktotheMAVandtransferredthecontentstotheMAV’s hydrogen tanks. I’vesaid this many times before,but: Hurray for standardizedvalvesystems!

“Johanssen, got his orbityet?”“I have interval pings.
Working out our interceptrangeandvelocity…”Martinez and Lewis stared
at Johanssen as she broughtup the intercept calculationsoftware. Normally, orbits
would be worked out byVogel, but he was otherwiseengaged. Johanssen was hisbackupfororbitaldynamics.“Intercept velocity will be
elevenmeterspersecond…,”shebegan.“I can make that work,”
Becksaidovertheradio.“Distance at intercept will
be—”Johanssen stoppedandchoked. Shakily, she
continued. “We’ll be sixty-eight kilometers apart.” Sheburiedherfaceinherhands.“Did she say sixty-eight
kilometers!?” Beck said.“Kilometers!?”“God damn it,” Martinez
whispered.“Keep it together,” Lewis
said. “Work the problem.Martinez,isthereanyjuiceintheMAV?”
“Negative, Commander,”Martinez responded. “Theyditched the OMS system tolightenthelaunchweight.”“Then we’ll have to go to
him. Johanssen, time tointercept?”“Thirty-nine minutes,
twelve seconds,” Johanssensaid,tryingnottoquaver.“Vogel,” Lewis continued,
“how far can we deflect in
thirty-nine minutes with theionengines?”“Perhaps five kilometers,”
heradioed.“Not enough,” Lewis said.
“Martinez, what if we pointour attitude thrusters all thesamedirection?”“Depends on how much
fuel we want to save forattitude adjustments on thetriphome.”
“Howmuchdoyouneed?”“Icouldgetbywithmaybe
twenty percent of what’sleft.”“All right, if you used the
othereightypercent—”“Checking,”Martinezsaid,
running the numbers on hisconsole. “We’d get a delta-vof thirty-one meters persecond.”“Johanssen,” Lewis said.
“Math.”“In thirty-nine minutes
we’d deflect…,” Johanssenquickly typed, “seventy-twokilometers!”“Therewego,”Lewissaid.
“Howmuchfuel—”“Use seventy-five point
five percent of remainingattitude adjust fuel,”Johanssensaid.“That’llbringtheinterceptrangetozero.”
“Doit,”Lewissaid.“Aye, Commander,”
Martinezsaid.“Holdon,”Johanssensaid.
“That’ll get the interceptrange to zero, but theintercept velocity will beforty-twometerspersecond.”“Then we have thirty-nine

AS A chemist, Vogel knewhowtomakeabomb.Infact,much of his training was toavoid making them bymistake.The ship had few

Such is thenature of combustion in pureoxygen.
Vogel measured the sugarcarefully. He poured it intothe strongest container hecould find, a thick glassbeaker. The strength of thecontainerwasasimportantasthe explosive.

needed.It’dbeaprettyshittylong-range ship if it couldn’trecover from adecompression.After Johanssen gave us
the all clear,Dr.Bossy-Beckmade me wait while he firsttookoffhissuit,thentookoffmine. After he pulled myhelmet off, he lookedshocked. I thought maybe Ihad a major head wound orsomething, but it turns out it
wasthesmell.It’s been a while since I
washed…anything.After that, it was X-rays
andchestbandageswhile therest of the crew checked theshipfordamage.Then came the (painful)
high fives, followed bypeople staying as far awayfrom my stench as possible.We had a few minutes of
reunion before Beck shuttledeveryone out. He gave mepainkillers and told me toshower as soon as I couldmove my arms. So now I’mwaiting for the drugs to kickin.I think about the sheer
numberofpeoplewhopulledtogetherjusttosavemysorryass, and I can barelycomprehend it. Mycrewmates sacrificed a year
oftheirlivestocomebackforme. Countless people atNASAworkeddayandnightto invent rover and MAVmodifications. All of JPLbusted their asses to make aprobe that was destroyed onlaunch. Then, instead ofgivingup,theymadeanotherprobe to resupply Hermes.The China National SpaceAdministration abandoned aproject they’dworked on for
years just to provide abooster.The cost for my survival
must have been hundreds ofmillions of dollars. All tosaveonedorkybotanist.Whybother?Well, okay. I know the
answer to that. Part of itmight be what I represent:progress, science, and theinterplanetary future we’vedreamedofforcenturies.But
really, they did it becauseevery human being has abasic instinct to help eachother out. It might not seemthat way sometimes, but it’strue.If a hiker gets lost in the
mountains, people willcoordinateasearch.Ifatraincrashes,peoplewilllineuptogive blood. If an earthquakelevels a city, people all overthe world will send
emergency supplies. This isso fundamentally human thatit’s found in every culturewithout exception.Yes, thereare assholes who just don’tcare, but they’re massivelyoutnumbered by the peoplewhodo.Andbecauseofthat,Ihadbillionsofpeopleonmyside.Prettycool,eh?Anyway,my ribs hurt like
hell,my vision is still blurry
from acceleration sickness,I’m really hungry, it’ll beanother 211 days before I’mback on Earth, and,apparently, I smell like askunk took a shit on somesweatsocks.This is thehappiestdayof
mylife.
