1. SpaceX Aces Final Major Test Before First Crew Mission

SpaceX performed a dramatic high-altitude test flight Sunday of the company’s Crew Dragon capsule over Florida’s
Space Coast, testing the human-rated ship’s ability to escape a rocket failure and save its crew before two NASA
astronauts strap in for a flight to the International Space Station as soon as this spring.
The unusual test flight included an intentional failure of the Crew Dragon’s Falcon 9 rocket about a minute-and-a-
half after liftoff from the Kennedy Space Center. The rocket, with a recycled first stage booster flown three previous
times, disintegrated in a fireball high over the Atlantic Ocean as the crew capsule sped away from the top of the
launcher with a powerful boost from eight SuperDraco engines.
The SuperDraco engines — mounted around the circumference of the gumdrop-shaped crew capsule — fired
around eight seconds to carry the spaceship a safe distance from the Falcon 9 rocket after the booster’s first stage
engines shut down, a standard part of the launch escape sequence.
The Crew Dragon arced on a ballistic trajectory to a top speed of about Mach 2.2 and a peak altitude of about
131,000 feet, according to Elon Musk, SpaceX’s founder and chief executive. The capsule then deployed four main
parachutes for a splashdown in the Atlantic Ocean roughly 20 miles (32 kilometers) east of the Kennedy Space
Center.
Musk, NASA officials and astronauts were pleased with the performance of the Crew Dragon’s launch escape
system. “I’m super fired up,” Musk said. “This is great … We’re looking forward to the next step.”
NASA has signed agreements with SpaceX valued at more than $3.1 billion since 2011 to fund the design,
development, construction and testing of the Crew Dragon spacecraft.
The next major step for the Crew Dragon program is the capsule’s first trip to space with astronauts. The Crew
Dragon’s in-flight abort test Sunday was the last major flight demonstration of a full-scale Crew Dragon spacecraft
before its first launch with humans on-board.

Veteran NASA shuttle fliers Doug Hurley and Bob Behnken are training for the mission — designated Demo-2 — to
fly the Crew Dragon to the International Space Station.
Musk said after Sunday’s in-flight abort test that the Demo-2 mission would likely launch in the second quarter of
this year — between the beginning of April and the end of June — although rocket and spacecraft hardware for the
Demo-2 flight could be in place at the Kennedy Space Center by the end of February or early March.
“The hardware necessary for first crewed launch, we believe, will be ready by the end of February,” Musk said.
“However, there’s still a lot of work once the hardware is ready to cross-check everything, triple-check, quadruple-
check, go over everything again so that every stone has been turned over three or four times.
“And there is also the schedule for getting to (the) space station because space station has a lot of things going to
it, so what’s the right timing for this?” Musk said. “The sort of collective wisdom at this point is we’re highly
confident the hardware will be ready in Quarter 1, most likely the end of February, but no later than March, and
that it and it would appear probable that the first crew launch would occur in the 2nd Quarter.”
In the meantime, SpaceX will collect all the data from the Crew Dragon abort test and analyze the results for any
potential problem areas. NASA is also reviewing numerous Crew Dragon data packages provided by SpaceX before
agreeing to fly Hurley and Behnken on SpaceX’s next crew capsule launch.
SpaceX plans at least two more atmospheric drop tests of the Crew Dragon parachute system to gain more
confidence in the capsule’s decelerators, which have been a problem area on the project after chute failures on a
cargo-carrying Dragon spacecraft and in Crew Dragon testing.
Engineers found that NASA was using wrong assumptions in models that predict how much force parachutes
experience on spacecraft returning to Earth. Data from testing showed the parachute risers, or suspension lines,
encountered more significant loads than expected, raising concerns about chutes across the agency’s human
spaceflight programs, including on the Starliner commercial crew capsule being developed by Boeing.
SpaceX and NASA agreed to switch to a new generation of Crew Dragon parachutes dubbed the Mark 3, and testing
of the new Mark 3 chutes — made by a company named Airborne Systems — has proceeded without failure since
late last year.
Sunday’s in-flight abort test provided the parachute engineers with another successful test of the Mark 3 chutes,
adding additional confidence about the system’s reliability.
NASA Administrator Jim Bridenstine called Sunday’s abort test “another amazing milestone” in the agency’s nearly
decade-long effort to resume crew launches to the space station from U.S. soil.
“Make no mistake, there’s a lot left to do,” Bridenstine said. “We have a number of parachute tests upcoming, and
of course, we’re going to get a lot of data from this particular test. So we’re not quite there yet, but by all accounts,
this was a very successful test.”
After a one-day delay due to rough seas in the splashdown zone — and a two-and-a-half-hour hold Sunday to wait
for improved winds — the Crew Dragon spacecraft lifted off on top of a SpaceX Falcon 9 rocket at 10:30 a.m. EST
(1530 GMT) Sunday from pad 39A at Kennedy, the same launch pad once used by NASA’s Saturn 5 moon rockets
and space shuttles.
The 215-foot-tall (65-meter) rocket flew off the launch pad powered by nine kerosene-fueled Merlin 1D engines and
pitched on an easterly trajectory from the Florida spaceport.
The Falcon 9 surpassed the speed of sound in less than a minute, and the Crew Dragon’s pre-programmed escape
sequence initiated around 84 seconds after liftoff, when the rocket was at an altitude of roughly 62,000 feet (19
kilometers). The abort was triggered soon after the point in the launch sequence where the booster and capsule
experience the most extreme aerodynamic pressures.

2. Building Blocks of Life Spotted on Rosetta’s Comet Hint at
Composition of Its Birthplace

Observations from ESA’s Rosetta spacecraft are shedding light on the mysterious make-up of Comet
67P/Churyumov-Gerasimenko, revealing a mix of compounds thought to be essential precursors to life – including
salts of ammonium and a particular type of hydrocarbons.
These new studies suggest the comet gleaned this material from the pre-solar cloud where the Solar System
formed 4.6 billion years ago.
Comets have a nucleus consisting of ice and dust, from which material sublimates when warmed by sunlight to form
a gaseous enveloping ‘coma’. These comas contain a mix of molecules that largely match theoretical predictions,
with one outstanding exception: nitrogen gas, which is usually present in far smaller amounts than expected.
“The reason behind this nitrogen depletion has remained a major open question in cometary science,” says Kathrin
Altwegg of the University of Bern, Switzerland, principal investigator for the Rosetta Orbiter Spectrometer for Ion
and Neutral Analysis (ROSINA) instrument and lead author of a new study.
“Using ROSINA observations of Comet 67P, we discovered that this ‘missing’ nitrogen may in fact be tied up in
ammonium salts that are difficult to detect in space.”
Ammonia, a molecule comprising one nitrogen and three hydrogen atoms, is one of the main carriers of volatile
nitrogen, and readily combines with various acids found in both the space between stars and in cometary ice to
form salts. These ammonium salts are thought to be the starting point for far more complex compounds – such as
urea and glycine, the latter of which was also found on Rosetta’s comet – that are known to be precursors to life as
we know it on Earth.
“Finding ammonium salts on the comet is hugely exciting from an astrobiology perspective,” adds Kathrin. “This
discovery highlights just how much we can learn from these intriguing celestial objects.”

Kathrin and colleagues used ROSINA data gathered during the final phase of the mission, from when Rosetta was
performing close flyovers of the comet in September 2016. These data were somewhat serendipitous: Rosetta
ventured closer to 67P than ever before, reaching just 1.9 km above the comet’s surface, and became completely
enshrouded by dust.
“Because of the dusty environment at the comet, and the rotation of Earth, we were not able to readily
communicate with Rosetta via our antennas at the time and had to wait until the next morning to reestablish our
communication link,” says Kathrin.
“None of us slept well that night! But both Rosetta and ROSINA ended up behaving perfectly, flawlessly measuring
the most abundant and most diverse mass spectra yet, and revealing many compounds we had never spotted on
67P before.”
Adding to this investigation of 67P, another recent study made use of a different instrument on Rosetta, the Visible
and Infrared Thermal Imaging Spectrometer (VIRTIS), which operated until May 2015, to explore the properties of
the comet’s nucleus.
The researchers explored several million infrared spectra gathered with VIRTIS and discovered clear signs of
hydrogen and carbon chains known as organic aliphatic compounds – the first time such compounds have been
spotted on the surface of a cometary nucleus.
“Where – and when – these aliphatic compounds came from is hugely important, as they are thought to be
essential building blocks of life as we know it,” explains lead author Andrea Raponi of INAF, the National Institute
for Astrophysics in Italy. “The origin of material such as this found in comets is crucial to our understanding of not
only our Solar System, but planetary systems throughout the Universe.”
Comets are flung inwards towards the Sun from the outer reaches of the Solar System, and may deliver material to
the inner planets as they travel. This material is thought to have either come from the young, still-forming Sun, or
from the interstellar medium.
“We found that the nucleus of Comet 67P has a composition similar to the interstellar medium, indicating that the
comet contains unaltered presolar material,” says co-author Fabrizio Capaccioni, also of INAF and principal
investigator for VIRTIS.
“This composition is also shared by asteroids and some meteorites that we have found on Earth, suggesting that
these ancient, rocky bodies locked up various compounds from the primordial cloud that went on to form the Solar
System.”
“This may mean that at least a fraction of the organic compounds in the early Solar System came directly from the
wider interstellar medium – and thus that other planetary systems may also have access to these compounds,” adds
Raponi.
Rosetta explored Comet 67P for over two years, ending its mission by crash-landing on the comet on 30 September
2016. “Although Rosetta operations ended over three years ago, it is still offering us an incredible amount of new
science and remains a truly ground-breaking mission,” adds Matt Taylor, ESA’s Rosetta Project Scientist.
“These studies tackled a couple of open questions in cometary science: why comets are depleted in nitrogen, and
where comets got their material from. Inspiring discoveries such as these help us to understand a great deal more
about not only comets themselves, but the history, characteristics and evolution of our entire cosmic
neighborhood.”

3. A Second Planet May Have been Found Orbiting Proxima Centauri!
And it’s a Super Earth.
An artist’s rendering of the Proxima Centauri system shows the newly discovered exoplanet Proxima c (on the right),
which orbits its host star in about 5.2 years. The smaller Proxima b, shown on the left, was discovered in 2016. Proxima
Centauri is just 4.3 light-years from Earth.
Lorenzo Santinelli
Astronomers have discovered another candidate exoplanet orbiting our neighbor, Proxima Centauri, about 4.2 light
years away. A paper announcing these results was just published in the journal Science Advances. If confirmed, it
will be the second exoplanet orbiting the star.
It was big news in 2016 when astronomers discovered a planet orbiting Proxima Centauri (PC,) the nearest star to
our Sun. That planet, named Proxima b, is potentially habitable, and at the time there was speculation that we
could send a robotic explorer there in only a few decades. The discovery of a second planet, even though it’s likely
too far away from its star for liquid water, is intensifying interest in the PC system.
The discoverers of this new planet, Proxima c, say that follow-up observations are needed to confirm it as a planet.
Changes in the stellar activity of Proxima Centauri indicated the presence of another planet. But they also say that
the data they have can’t be explained in terms of any stellar activity itself. Due to its proximity, and also its angular
separation from the star, it is a prime candidate for follow-up observations—and even imaging—with next
generation telescopes.
Proxima c’s mass is about half that of Neptune and its orbit is about 1.5 times that of Earth. Its temperature is
about -200 C, if it has no atmosphere. Proxima Centauri has undergone intense astronomical scrutiny in the last few
years, and that has ruled out the presence of any Jupiter-sized planets between 0.8 and 5+ astronomical units from
the star. But finding Proxima c is still surprising, because its presence challenges our models of how super-Earths
form and evolve.
The lead author of this study is Mario Damasso from the INAF Astrophysical Observatory of Turin, Italy. The study
is titled “A low-mass planet candidate orbiting Proxima Centauri at a distance of 1.5 AU.” It was published on
January 15th, 2020.
Hugh Jones, a Professor of Astrophysics at Hertfordshire University, was also involved in the study. In an article in
“The Conversation,” Jones pointed out how difficult it can be to separate data showing the presence of a planet,
7 of 13
from data showing stellar activity at the host star. “Just like our sun, Proxima has spots caused by regions of
intense magnetic activity which are moving in and out of view, changing in intensity on a variety of timescales.
These features need to be considered when searching for any planetary signals.”
Even though stellar activity doesn’t match the data, the discoverers are being cautious until follow-up observations
can either confirm or deny the presence of Proxima c, and definitively rule out stellar activity.
The discovery of this new candidate exoplanet is contained in this new paper, but the history goes back a few
years. Multiple teams of scientists have scoured Proxima Centauri for exoplanets. Much of their work depended on
radial velocity data, notably from the ESO’s HARPS (High Accuracy Radial velocity Planet Searcher.) Study by study,
astronomers have excluded the presence of certain mass-range planets within certain AU ranges from PC.
A 1999 study excluded the presence of any planets beyond 1700 AUs of PC, because PC itself orbits Alpha Centauri
AB. A 2019 study set an upper limit of 0.3 Jupiter masses for any planet within 10 AU of PC. That same study
excluded the presence of planets between 10 and 50 AU in the mass range 0.3 to 8 masses of Jupiter. Other
studies put on more constraints.
But astronomers also know that red dwarfs host more small planets than other types of stars. So they kept looking.
Due to its proximity, the Proxima Centauri system is an observable laboratory for understanding other solar
systems. And its presence and proximity might spur further technological development needed to study it and other
systems in more detail.
As Hugh Jones said in his article at The Conversation, “Ultimately, the discovery of multiple signals from the very
closest star shows that planets are more common than stars. Proxima represents an excellent location for
understanding the closest exoplanets and developing new technologies to better understand the universe we live
in.”
Proxima c’s existence is problematic, or at least significant, for our planet formation models. Among super-Earth
planets around low-mass stars detected by radial velocity, Proxima c would have both the longest period and the
lowest mass. It would also be the furthest distance from its parent star than the frost line in the original
protoplanetary disk. The frost line was probably at 0.15 AU.
The authors say that it’s unlikely that Proxima c was kicked out from its initial position closer to the star due to
some instability, “because its orbit is consistent with a circular one and because of the absence of more massive
planets on shorter orbital distance.”
In their paper, they say, “The formation of a super-Earth well beyond the snowline challenges formation models
according to which the snowline is a sweet spot for the accretion of super-Earths, due to the accumulation of icy
solids at that location.”

The Night Sky
Thursday, Jan. 23
• Zero-magnitude Capella, very high in the east after dark, and zero-magnitude Rigel, in Orion's foot, have
almost the same right ascension. This means they cross your sky’s meridian at almost exactly the same time:
around 9 p.m. now, depending on how far east or west you live in your time zone. (Capella goes exactly
through your zenith if you're at latitude 46°N.) So whenever Capella passes highest, Rigel always marks true
south over your landscape, and vice versa.
Friday, Jan. 24
• Right after dark face east and look very high for bright Capella, the Goat Star. To the right of it, by a couple
of finger-widths at arm's length, is a small, narrow triangle of 3rd and 4th magnitude stars known as "the
Kids." Though they're not exactly eye-grabbing, they form a never-forgotten asterism with Capella.
• New Moon (exact at 4:42 p.m. EST).
Saturday, Jan. 25
• After dark now the Great Square of Pegasus is declining low in the west, tipped onto one corner. It's far to
the upper right of Venus. Meanwhile the Big Dipper is creeping up in the north-northeast, tipped up on its handle.

• Sirius twinkles brightly below Orion in the
southeast after dinnertime. Around 8 p.m.,
depending on your location, Sirius shines precisely
below fiery Betelgeuse in Orion's shoulder. How
accurately can you time this event for your location,
perhaps using the vertical edge of a building? Of the
two, Sirius leads early in the evening; Betelgeuse
leads later.
• As dawn brightens on Wednesday morning, spot
the slim waning crescent Moon quite low in the
southeast. The bulge of its curve points lower left to
even-lower Jupiter, 6° or 7° from it (at dawn for
North America). The Moon occults Jupiter for New
Zealand and parts of Australia around 3h January
23rd UT.
Wednesday, Jan. 22
• The Gemini twins lie on their sides on January
evenings, left of Orion. Their head stars, Castor and
Pollux, are farthest from Orion, one over the other.
Castor is the top one. The Castor figure's feet are
just left of Orion's very dim Club.

ESA Opens Oxygen Plant – Making Air Out Of Moondust
(Note: NASA has a similar project underway as covered in the Sept. 17, 2019 Space News Update)
ESA’s technical heart has begun to produce oxygen out of simulated moondust.
A prototype oxygen plant has been set up in the Materials and Electrical Components Laboratory of the European
Space Research and Technology Centre, ESTEC, based in Noordwijk in the Netherlands.
“Having our own facility allows us to focus on oxygen production, measuring it with a mass spectrometer as it is
extracted from the regolith simulant,” Beth Lomax of the University of Glasgow, whose PhD work is being supported
through ESA’s Networking and Partnering Initiative, harnessing advanced academic research for space applications.
“Being able to acquire oxygen from resources found on the Moon would obviously be hugely useful for future lunar
settlers, both for breathing and in the local production of rocket fuel.”
ESA research fellow Alexandre Meurisse adds: “And now we have the facility in operation we can look into fine-
tuning it, for instance by reducing the operating temperature, eventually designing a version of this system that
could one day fly to the Moon to be operated there.”
Samples returned from the lunar surface confirm that lunar regolith is made up of 40–45% percent oxygen by
weight, its single most abundant element. But this oxygen is bound up chemically as oxides in the form of minerals
or glass, so is unavailable for immediate use.
ESTEC’s oxygen extraction is taking place using a method called molten salt electrolysis, involving placing regolith in
a metal basket with molten calcium chloride salt to serve as an electrolyte, heated to 950°C. At this temperature the
regolith remains solid. But passing a current through it causes the oxygen to be extracted from the regolith and
migrate across the salt to be collected at an anode. As a bonus this process also converts the regolith into usable
metal alloys.
In fact this molten salt electrolysis method was developed by the UK company Metalysis for commercial metal and
alloy production. Beth’s PhD involved working at the company to study the process before recreating it at ESTEC.

image is a pile of simulated lunar soil, or regolith; on the

“At Metalysis, oxygen produced by the process is an unwanted by-product and is instead released as carbon dioxide
and carbon monoxide, which means the reactors are not designed to withstand oxygen gas itself,” explains Beth.
“So we had to redesign the ESTEC version to be able to have the oxygen available to measure. The lab team was
very helpful in getting it installed and operating safely.”
The oxygen plant runs silently, with the oxygen produced in the process is vented into an exhaust pipe for now, but
will be stored after future upgrades of the system.
“The production process leaves behind a tangle of different metals,” adds Alexandre, “and this is another useful line
of research, to see what are the most useful alloys that could be produced from them, and what kind of applications
could they be put to. Could they be 3D printed directly, for example, or would they require refining? The precise
combination of metals will depend on where on the Moon the regolith is acquired from – there would be significant
regional differences.”
The ultimate aim would be to design a ‘pilot plant’ that could operate sustainably on the Moon, with the first
technology demonstration targeted for the mid-2020s. “ESA and NASA are heading back to the Moon with crewed
missions, this time with a view towards staying,” says Tommaso Ghidini, Head of ESA’s Structures, Mechanisms and
Materials Division.
“Accordingly we’re shifting our engineering approach to a systematic use of lunar resources in-situ. We are working
with our colleagues in the Human and Robotics Exploration Directorate, European industry and academia to provide
top class scientific approaches and key enabling technologies like this one, towards a sustained human presence on
the Moon and maybe one day Mars.”
