Description
The Almaz-1 was a satellite dedicated to providing radarimaging capabilities used in geophysical, agricultural,geological and environmental applications. The Almaz("diamond") spacecraft design was based on the MIR/Salyutmanned orbital station and a class of Heavy Cosmos militaryspacecraft (Cosmos 929). The Almaz-1 spacecraft had two100 m**2 solar panels and batteries to provide power. Thespacecraft used reaction wheels to maintain attitude and 3-axis stabilization. The interior was pressurized by nitrogen tosea level. The Almaz program had its origins in 1981, when thespaceraft was originally designed as a military reconnaissancecraft. Almaz-1 was designed and manufactured and operatedby NPO Machinostroenye. The sensor was a 3 GHz (10 cm) S-band Synthetic Aperature Radar (SAR) that used two 1.5 x 15m slotted waveguide antennas to obtain a resolution of 15meters per pixel. Data was temporarily stored on board usingvideo tape recorders, and subsequently down-linked to theground stations via the Luch GEO satellite. Almaz-1 alsocarried a radiometric scanner system (RMS) for infraredsounding of the Earth's surface. The Almaz-1 spacecraftreentered the Earth's atmosphere on October 17, 1992 after 18months in orbit out of an expected 30-month mission. Thespacecraft exectuted a controlled descent over the PacificOcean after the maneuvering fuel was unexpectedly exhaustedbecause of frequent orbit re-positioning due to increased solaractivity. Almaz-1 was preceded by Cosmos 1870 whichsuccesfully carried the Almaz SAR prototype.

Description
A fifth-generation Canadian telecommunications satellite, AnikE2 was launched via an Ariane 44P booster from Kourou,French Guiana. The satellite was the largest North Americandomestic commsat launched to date and required the extra liftof 4 Ariane solid propellant strap-on boosters. The Anik Eseries carried two dozen 12-W C-band transponders plus sixspares, and sixteen 50-W Ku-band transponders, with twospares. Coverage extended throughout Canada and a largeportion of the US. The satellite was manufactured by SparAerospace for TELESAT Canada. The bus was provided byGE Astro-Space. The main body measured 2.8 by 2.3 by 2.4m; solar arrays, generating 3888 W, spanned 21.5 m. Anik E2arrived on station at 107.3 deg. w as planned, but its orbitaldebut was dampened when the C-band antenna did notdeploy. With earth sensors covered by the stuck antenna,operations were impossible. For nearly three months, thesatellite was spun up, slowed down, heated and cooled inrepeated attempts to free the antenna. Telsat was prepared towrite the bird off. Relentless engineers tried a series of dualspin turn maneuvers, with the satellite spinning up the 4.5 rpm.On July 3, the C-band antenna swung free. Although therescue maneuvers used about a year's worth of fuel, Anik E2still had a 12-year life expectancy. After a two month testphase, Ku-band service was transferred to the new satellitefrom Anik C1, and C-band service from Anik D1 and D2.

Description
Aurora 2, an Alaskan-owned telecommunications satellite, waslaunched from Cape Canaveral aboard a Delta booster rocket.It provided telephone, television, maritime, radio andemergency communications service for the northern state'slong distance carrier, Alascom, as well as radio and dataservices for GE Americom. The satellite carried 32 C-bandtransponders (24 primary and 6 redundant) operating at 6/4GHz. Sixteen of the 24 channels served Alaskan customers, 8served US business. Built by GE Astro-Space for Alascom,Aurora 2 was box-shaped, measuring 1 by 1.64 by 1.4 m. Twothree-panel solar arrays, totalling 13 sq. m, extended fromeither side of the main body. The fixed dual-polarizationreflector antenna covered the continental US, Alaska andHawaii. It replaced Aurora 1, retired after 9 years of service.Stationed above 139 deg. w, Aurora 2 became operational inJuly. It has a 12-year life expectancy.

Description
The Compton Gamma-Ray Observatory (GRO) is one ofNASA's four "Great Observatories". GRO's specific mission isto study the sources and astrophysical processes (e.g.,nuclear reactions, electron bremsstrahlung, matter-antimatterannihilation, elementary particle producation and decay,Compton scattering, and synchrotron radiation) that producethat highest energy electromagnetic radiation from the cosmos.GRO carries a complement of four instruments that providesimultaneous observations covering over five decades ofenergy from 0.1 MeV to 30 GeV: the Burst and TransientSource Experiment (BATSE), the Oriented ScintillationSpectrometer Experiment (OSSE), the Imaging ComptonTelescope (COMPEL), and the Energetic Gamma-RayExperiment Telescope (EGRET). The initial phase of thescience program consists of a near-uniform survey of thecomplete celestial sky followed by specific concentrations inlater phases; a 6 to 10-year mission lifetime is anticipated. TheGRO spacecraft is a 3-axis stabilized, free-flying spacecraftthat is capable of pointing at any celestial target for a period of14 days or more with an accuracy of 0.5 degree. Attitudedetermination accuracy is 2 arc minutes. If a significantcelestial event should occur at some other location, GRO iscapable of maneuvering to any orientation, by groundcommand, within 36 hours. Absolute timing is accurate to 0.1ms. The observatory has an onboard propulsion system, withapproximately 1860 kg of monopropellant hydrazine, for orbitmaintenance. Fuel is reserved for a controlled reentry, into adefined area of the Pacific Ocean at mission demise.

Description
Cosmos 2109 was a Soviet Global Navigation Satellite System(GLONASS) satellite launched from the Baikonur cosmodromeaboard a Proton rocket. Originally established in order tolocate the Soviet Union's civil aircraft and its merchant andfishing vessels, the signals were used by many American GPSsystem receivers as a complement/backup to the GPS systemitself. The operational system contained 21 satellites in 3orbital planes, with 3 on-orbit backups. Each satellite wasidentified by its slot number, which defined the orbital plane (1-8, 9-16, 17-24) and the location within the plane. The 3 orbitalplanes were separated 120 degrees, and the satellites withinthe same orbit plane by 45 degrees. The orbits were roughlycircular with an inclination of about 64.8 degrees, a semi-axisof 25,440 km, and a period of 11h 15m 44s.
The 3-axis stabilized spacecraft possessed a mass of about1,400 kg, a slight increase over the 1,250 original model. Thediameter and height of the satellite bus were approximately 2.4m and 3.7 m, respectively, with a solar array span of 7.2 m foran electrical power generation capability of 1.6 kW atbeginning of life. The aft payload structure housed 12 primaryantennas for L-band transmissions. Laser corner-cubereflectors were also carried to aid in precise orbit determinationand gedetic research.

Description
Cosmos 2123 was a Soviet navigation satellite launched fromthe Plesetsk cosmodrome aboard a Kosmos 11 rocket. It waspositioned in plane 13 of the constellation. It was used fortesting of components and equipment of a space navigationsystem being set up to determine the position of civil aircraftand ships of the USSR merchant marine and fishing fleet atany point on the oceans and seas.
Development of this second generation Soviet navigationsatellite system represented a collaboration between the Navy,Academy of Sciences, and Ministry of Shipping. The basiswas the Parus / Tsiklon-B doppler navigation system, butallowing asynchronous operation of on-board equipment withonly essential equipment receiving a timer interrupt.Development began in 1974 with some preliminary workalready accomplished. The Tsikada system provided globalnavigation for both the Soviet Navy and commercial shipping.Prime contractor was KBPM/Reshetnev. PO Polyot, A SKlinyshkov provided synchronisation equipment. NIIRadiopribor under N Ye Ivanov provided cryptography andspacecraft navigation systems. Flight trials began in 1976under Admiral A I Rassokho. The system was accepted intomilitary service in 1979.

Description
The lowest level of the three-tier communications satelliteconstellation was populated with two distinct systems devotedto military and government communications. Both systemswere assessed to be simple store-dump repeaters which wereparticularly useful in relaying traffic between the RussianFederation and overseas stations or forces. These Strela(which means "Arrow" in Russian) satellites recorded radiomessages transmitted by Russian intelligence agentsworldwide and relayed them when flying over Moscow.Debuting in 1970 was a system of small (61 kg, 0.80 m by0.75 m) relay satellites launched from Plesetsk by the Kosmosbooster in groups of eight. Although the mean altitude of thisconstellation was near 1500 km, each set of eight Strela 1satellites was normally dispersed into slightly elliptical orbitswith mean altitudes between 1430 and 1490 km. Theintentional orbital period differences of about 0.15 min ensuredthat the satellites would become randomly spaced about theorbital plane shortly after launch. Unlike the lower altitudeconstellation, this network relied on a single orbital plane withan inclination of 74 deg which was replenished on the averageof once each year. The last mission in this network was inJune 1992, and the network has now been superseded by themore modern and capable Strela 3 system.

Description
The lowest level of the three-tier communications satelliteconstellation was populated with two distinct systems devotedto military and government communications. Both systemswere assessed to be simple store-dump repeaters which wereparticularly useful in relaying traffic between the RussianFederation and overseas stations or forces. These Strela(which means "Arrow" in Russian) satellites recorded radiomessages transmitted by Russian intelligence agentsworldwide and relayed them when flying over Moscow.Debuting in 1970 was a system of small (61 kg, 0.80 m by0.75 m) relay satellites launched from Plesetsk by the Kosmosbooster in groups of eight. Although the mean altitude of thisconstellation was near 1500 km, each set of eight Strela 1satellites was normally dispersed into slightly elliptical orbitswith mean altitudes between 1430 and 1490 km. Theintentional orbital period differences of about 0.15 min ensuredthat the satellites would become randomly spaced about theorbital plane shortly after launch. Unlike the lower altitudeconstellation, this network relied on a single orbital plane withan inclination of 74 deg which was replenished on the averageof once each year. The last mission in this network was inJune 1992, and the network has now been superseded by themore modern and capable Strela 3 system.

Description
Cosmos 2133 was part of a Soviet constellation of satellitescomprised of an echelon of the Missile Attack Warning System(SPRN), which was operated by the Air Defense Forces of theMinistry of Defense. According to Soviet officials, the earlywarning satellites could detect missile launches within 20seconds of lift-off.
Each satellite possessed a perigee of about 600 km, anapogee of nearly 40,000 km, and an inclination of 63 degrees.This orbit was superfically similar to that employed by theMolniya communications satellites but was distinguished byinitial argument of perigee 316-319 degrees, including to theMolniya 280-288 degree arguments of perigee. The seeminglyminor difference significantly affected the shape of thesatellite's groundtrack in the Northern Hemisphere.
Russian early warning spacecraft were more affected bygravitational perturbations due to their higher argument ofperigee and, therefore, performed periodic station-keepingmaneuvers to maintain an acceptable groundtrack. In addition,the argument of perigee migrated slightly over time (due toinclination variations), causing an alteration in the shape of thegroundtrack. Instead of expending additional propellant toprevent the argument of perigee shift, Russian spacecraftcontrollers altered the satellite's ascending node. This had theeffect of "stabilizing" the apogee point about which surveillanceoperations were performed.

Description
Cosmos 2135 was part of a 6-satellite Russian militarynavigation system distributed in orbital planes spaced 30degrees apart, and launched from the Plesetsk cosmodromeaboard a Cosmos rocket. Navigation information was derivedfrom Doppler-shifted VHF transmissions (approximately 150and 400 MHz) of the satellite position and orbital data. Byacquiring fixes from several satellite, a user's location could becalculated with an accuracy of 100 m. The time needed toascertain a position was dependent upon the user's latitudeand the number of operational spacecraft in orbit. Normally,accurate location determination could be made within 1-2hours.

Description
Cosmos 2139 was a Russian Global Navigation SatelliteSystem (GLONASS) satellite launched from the Baikonurcosmodrome aboard a Proton rocket. Originally established inorder to locate the Soviet Union's civil aircraft and its merchantand fishing vessels, the signals were used by many AmericanGPS system receivers as a complement/backup to the GPSsystem itself. The operational system contained 21 satellites in3 orbital planes, with 3 on-orbit backups. Each satellite wasidentified by its slot number, which defined the orbital plane (1-8, 9-16, 17-24) and the location within the plane. The 3 orbitalplanes were separated 120 degrees, and the satellites withinthe same orbit plane by 45 degrees. The orbits were roughlycircular with an inclination of about 64.8 degrees, a semi-axisof 25,440 km, and a period of 11h 15m 44s.
The 3-axis stabilized spacecraft possessed a mass of about1,400 kg, a slight increase over the 1,250 original model. Thediameter and height of the satellite bus were approximately 2.4m and 3.7 m, respectively, with a solar array span of 7.2 m foran electrical power generation capability of 1.6 kW atbeginning of life. The aft payload structure housed 12 primaryantennas for L-band transmissions. Laser corner-cubereflectors were also carried to aid in precise orbit determinationand gedetic research.

Description
The Strela 3 system was a communications satellite constellation devoted to military and government communications.It was a simple store-dump repeater system which were particulatly useful in relaying non-essential traffic between theRussian Federation and overseas stations or forces. The Strela 3 system, which began in 1985, was launched by theTsyklon-3 booster from the Plesetsk cosmodrome into orbits near 1400 km at inclinations of 82.6 degrees with sixspacecraft stacked atop each launch vehicle. Two orbital planes were spaced 90 degrees apart, apparently eachcontained 10-12 operational spacecraft. Normally, two missions were conducted per year, suggesting an averagespacecraft life-time of approximately 24 months. The 220 kg spacecraft had a diameter of 1.0 m and a main bus heightof 1.5 m. A gravity-gradient beam was extended on-orbit to provide attitude stabilization.

Description
The lowest level of the three-tier communications satelliteconstellation is now populated with two distinct systemsdevoted to military and government communications. Bothsystems are assessed to be simple store-dump repeaterswhich were particularly useful in relaying non-essential trafficbetween the Russian Federation and overseas stations offorces. The first Strela (which means "Arrow" in Russian)system debuted in 1970 and consisted of 750 - 1000 kgsatellites deployed at mean altitudes of 800 km in three orbitalplanes inclined 74 degrees to the equator and spaced 120degrees apart. These Strela 2 spacecraft were launchedseparately by the Kosmos launch vehicle from the Plesetskcosmodrome into each orbital plane at intervals of 24-36months. The activity of these satellites could be monitored viaa characteristic CW beacon emitted on a frequency of 153.660MHz.

Description
Cosmos 2151 was a Russian ELINT (Electronic and SignalsIntelligence) satellite launched from the Plesetsk cosmodrome.
From 1965 to 1967 two dedicated ELINT systems were tested:the Tselina and the Navy's US. Both reached service, since theMinistry of Defence could not force a single system on themilitary services.
Tselina was developed by Yuzhnoye and consisted of twosatellites: Tselina-O for general observations and Tselina-D fordetailed observations. ELINT systems for Tselina were firsttested under the Cosmos designation in 1962 to 1965. The firstTselina-O was launched in 1970. The Tselina-D took a longtime to enter service due to delays in payload developmentand weight growth. The whole Tselina system was notoperational until 1976. Constant improvement resulted inTselina-O being abandoned in 1984 and all systems being puton Tselina-D.

Description
Cosmos 2154 was part of a 6-satellite Russian militarynavigation system distributed in orbital planes spaced 30degrees apart, and launched from the Plesetsk cosmodromeaboard a Cosmos rocket. Navigation information was derivedfrom Doppler-shifted VHF transmissions (approximately 150and 400 MHz) of the satellite position and orbital data. Byacquiring fixes from several satellite, a user's location could becalculated with an accuracy of 100 m. The time needed toascertain a position was dependent upon the user's latitudeand the number of operational spacecraft in orbit. Normally,accurate location determination could be made within 1-2hours.

Description
Cosmos 2155 was part of a Russian constellation of satellitescomprised of an echelon of the Missile Attack Warning System(SPRN), which was operated by the Air Defense Forces of theMinistry of Defense. According to Soviet officials, the earlywarning satellites could detect missile launches within 20seconds of lift-off.
Each satellite possessed a perigee of about 600 km, anapogee of nearly 40,000 km, and an inclination of 63 degrees.This orbit was superfically similar to that employed by theMolniya communications satellites but was distinguished byinitial argument of perigee 316-319 degrees, including to theMolniya 280-288 degree arguments of perigee. The seeminglyminor difference significantly affected the shape of thesatellite's groundtrack in the Northern Hemisphere.
Russian early warning spacecraft were more affected bygravitational perturbations due to their higher argument ofperigee and, therefore, performed periodic station-keepingmaneuvers to maintain an acceptable groundtrack. In addition,the argument of perigee migrated slightly over time (due toinclination variations), causing an alteration in the shape of thegroundtrack. Instead of expending additional propellant toprevent the argument of perigee shift, Russian spacecraftcontrollers altered the satellite's ascending node. This had theeffect of "stabilizing" the apogee point about which surveillanceoperations were performed.

Description
The Strela 3 system was a communications satelliteconstellation devoted to military and governmentcommunications. It was a simple store-dump repeater systemwhich were particulatly useful in relaying non-essential trafficbetween the Russian Federation and overseas stations orforces. The Strela 3 system, which began in 1985, waslaunched by the Tsyklon-3 booster from the Plesetskcosmodrome into orbits near 1400 km at inclinations of 82.6degrees with six spacecraft stacked atop each launch vehicle.Two orbital planes were spaced 90 degrees apart, apparentlyeach contained 10-12 operational spacecraft. Normally, twomissions were conducted per year, suggesting an averagespacecraft life-time of approximately 24 months. The 220 kgspacecraft had a diameter of 1.0 m and a main bus height of1.5 m. A gravity-gradient beam was extended on-orbit toprovide attitude stabilization.

Description
Cosmos 2163 was the third of the sixth generation photoreconnaisance satellites launched from the Baikonurcosmodrome using the Soyuz-U2 launch vehicle, which hadotherwise been restricted to supporting Soyuz-TM andProgress-M missions. The spacecraft was inserted into anorbital inclination of 64.8 degrees with mean operationalaltitudes normally between 240 and 260 km. The sixthgeneration spacecraft, believed to carry both film returncapsules and digital transmission capabilities, have only flownsix times; once each year during 1989-1993 and once in 1997.

Description
In 1969 KB Yuzhnoye introduced targets for exercise and testof PVO air defence and space tracking systems. The secondgeneration consisted of Taifun-1 and Taifun-2 satellites, whichdiffered in the type of equipment installed. In 1972 KB-3 underB E Khimrov, with the co-operation of assisting organisationsand the Ministry of Defence, completed the draft project. Thefirst Taifun-2 was completed in 1976. Flight trials wereconducted in the second half of the 1970's using Kosmos-3Mlaunch vehicles from Plesetsk and Kapustin Yar. The heads ofthe State Trials Commission were B N Karpov, N N Zhukov,and B G Zudin. Taifun-2 satellites were spherical in shape, 2m in diameter, with no external solar cells or antennae.

Description
Cosmos 2172 was a Russian military second generation globalcommand and control system (GKKRS) satellite launched fromthe Baiknour cosmodrome aboard a Proton K rocket. Thesesatellites were integrated with the Luch geostationary systemand featured retransmission of high rate data retransmission inthe centimetre wavelength range. While Luch handledcommunications between spacecraft and ground stations,Potok handled communications between fixed points anddigital data from the Yantar-4KS1 electroptical reconnaissancesatellite. Potok was the first communications spacecraft built bythe Lavochkin design bureau and used the Splav-2transponder by NPO Elas.
Potok is said by one account to have utilized the KAUR-4spacecraft bus. This had an active 3-axis orientation system,with a single central body from which extended 40 squaremetres of solar panels. Its basic structure was that of theKAUR-3, but it was equipped with completely new systems: adigital computer, plasma station-keeping engines, hydrazinemonopropellant orientation engines, and actively-scannedantennae arrays with 0.5 degrees antenna and 0.1 degreespacecraft pointing accuracy. Cosmos 2172 was stationed at13 deg W.

Description
Cosmos 2173 was part of a 6-satellite Russian militarynavigation system distributed in orbital planes spaced 30degrees apart, and launched from the Plesetsk cosmodromeaboard a Cosmos rocket. Navigation information was derivedfrom Doppler-shifted VHF transmissions (approximately 150and 400 MHz) of the satellite position and orbital data. Byacquiring fixes from several satellite, a user's location could becalculated with an accuracy of 100 m. The time needed toascertain a position was dependent upon the user's latitudeand the number of operational spacecraft in orbit. Normally,accurate location determination could be made within 1-2hours.

Description
DMSP 5D-2/F11 is one of a series of meteorological satellitesdeveloped and operated by the Air Force under the DefenseMeteorological Satellite Program (DMSP). This program,previously known as DAPP (Data Acquisition and ProcessingProgram), was classified until March 1973. The objective ofthis program is to provide global visual and infrared cloudcoverdata and specialized environmental data to supportDepartment of Defense operational weather analysis andforecasting requirements. Operationally, the program consistsof two satellites in sun-synchronous polar orbits, with theascending node of one satellite in early morning and the otherat local noon. The 6.4-m-long spacecraft is separated into foursections: (1) a precision mounting platform for sensors andequipment requiring precise alignment; (2) an equipmentsupport module containing the electronics, reaction wheels,and some meteorological sensors; (3) a reaction controlequipment support structure containing the third-stage rocketmotor and supporting the ascent phase reaction controlequipment; and (4) a 9.29-sq-m solar cell panel. Thespacecraft stabilization is controlled by a combination flywheeland magnetic control coil system so that sensors aremaintained in the desired earth-looking mode. One feature isthe precision-pointing accuracy of the primary imager to 0.01deg provided by a star sensor and an updated ephemerisnavigation system. This allows automatic geographicalmapping of the digital imagery to the nearest picture element.The operational linescan system is the primary data acquisitionsystem that provides real-time or stored, multi-orbit, day-and-night, visual and infrared imagery of clouds. A supplementarysensor package contains five special sensors: (1) a microwavetemperature sounder, (2) an X-ray spectrometer, (3) anionospheric/scintillation monitor, (4) a precipitating electron/ionspectrometer, and (5) a microwave imager. Either recorded orreal-time data are transmitted to ground-receiving sites by tworedundant S-band transmitters. Recorded data are read out totracking sites located at Fairchild AFB, Washington, and atLoring AFB, Maine, and relayed by SATCOM to Air ForceGlobal Weather Central, Offutt AFB, Nebraska. Real-time dataare read out at mobile tactical sites located around the world.Additional information concerning this satellite can be found inthe report by D. A. Nichols, "The Defense MeteorologicalSatellite Program," Optical Engineering, v. 14, n. 4, p. 273,July-August 1975.

Description
The first European Remote Sensing Satellite (ERS 1) was amajor element of the European Earth Observation Programcovering a number of disciplines including meteorology,climatology, oceanography, land resource inventory andmonitoring, geodesy and geodynamics. The objectives of ERS1 were primarily oriented towards ice and ocean monitoringwith all-weather high resolution active microwave imaging overland and coastal areas. The primary objectives were to meeteconomic and scientific needs to (1) develop and promoteapplications to further knowledge of ocean parameters, seastate and ice conditions and (2) increase the scientificunderstanding of coastal zones and ocean processes. TheERS 1 carried the following instruments: (1) Active MicrowaveInstrumentation (AMI), which combined a Synthetic ApertureRadar (SAR) and a wind scatterometer to acquire all-weatherimages over polar ice, coastal zones and land area and tomeasure wind field and wave spectra over oceans; (2) a RadarAltimeter (RA) to measure wave height, ocean surface windspeed and ice parameters; (3) the Along-Track ScanningRadiometer (ATSR), which consisted of two instruments:infrared radiometer (IRR) for measuring sea surface and cloudtop temperature and a microwave sounder (MWS) formeasuring total precipitable liquid and vapor water; (4) thePrecise Range and Range-rate Equipment (PRARE) toprovide accurate altitude measurements for geodeticapplications, sea surface topography, crustal dynamics andocean circulation; and (5) the Laser Retroreflector (LRR),which was a passive optical device used to assist satellitetracking. The ERS 1 spacecraft was based on the FrenchSPOT platform with a three axis stabilized earth pointedattitude control and a bias of 0.11 deg with an absolute errorrate of less than 0.0015 deg/s. The spacecraft consisted of thefollowing modules: Service Module (SM), Reaction ControlModule (RCM), Solar Array, PFM Thermal Control, PowerSupply Subsystem (PSS), Communications and Data HandlingSubsystem (CDHS), Attitude and Orbit Control Subsystem(AOCS), Flight Software, and Reaction and Self-mode ControlUnit. Power was supplied by two 5.8 x 2.4 m solar array panelsbacked up by four NiCd 24-Ah batteries. Attitude and orbitcontrol was maintained by horizon and Sun sensors andgyroscopes. Primary attitude control was provided by a set ofmomentum wheels and hydrazine thrusters. The ERS 1thermal control system was of a passive design complementedby an active heater system. The On-Board Computer (OBC)ran the flight software. All instrument computers were linked bythe On-Board Data-Handling (OBDH) system. All of theonboard processors were programmable during flight. Thespacecraft orbital orientation permitted a 3-day repeatcycle.The Payload Module consisted of the Payload

Description
Beginning in 1985 the USSR/CIS conducted annual unmannedspace missions dedicated to materials science research. ThePhoton (Foton) spacecraft used for these flights was aderivative of the 1960's era Vostok/Voskhod mannedspacecraft and the Zenit military reconnaissance satellites andwere very similar to the operational Bion and Resurs-Fsatellites. Prototype Photon satellites were launched during1985-1987 as Cosmos 1645, Cosmos 1744, and Cosmos1841. Since 1988, the spacecraft have been officiallydesignated as Photon.
The 6,200-kg spacecraft was 6.2 m in length with a maximumdiameter of 2.5 m and was divided into three major sections:the service/retro module, the payload capsule, and anequipment block. The 2.3 m diameter recoverable capsulehandled a payload of up to 700 kg and a volume of 4.7 mcubed. Electrical power was supplied entirely by storagebatteries with 400 W average per day allocated to the payload(up to 700 W for 90 minutes each day). Mission durations forthe 8 Photon flights to the end of 1992 were 13-16 days.
To minimize perturbation forces, thereby maximizingmicrogravity conditions, Photon spacecraft were placed in amildly eccentric orbit at 62.8 degrees inclination and were notmaneuvered during the mission. Prior to 1991 the annualPhoton missions had always been launched in April or May.Launches were performed by the Soyuz booster from thePlesetsk cosmodrome, and recoveries made in Kazakhstan inthe primary manned recovery region northeast of the Baikonurcosmodrome.
The planned 16-day Photon 7 flight was scheduled toexperiment on obtaining protein crystals and semiconductormaterials under microgravity conditions. The spacecraft alsocarried scientific apparatus devised by German and Frenchspecialists.

Description
GOES-X is a collective name assigned by NSSDC to the nextseries of geostationary and operational environmentalsatellites (GOES-I, -J, -K, -L, -M). This three-axis bodystabilized spacecraft carries: (1) a visible infrared spin-scanradiometer (VISSR) atmospheric sounder (VAS) for collectingradiance, cloudcover, atmospheric temperature and watervapor data; (2) a space environment monitor (SEM) thatincludes a three-axis magnetometer, an X-ray Sensor (XRS),an Energy Particle Sensor (EPS), and a High Energy Protonand Alpha Detector (HEPAD); and (3) a Data CollectionSystem (DCS) to relay data between ground based platformsand the NOAA Command and Data Acquision (CDA) Station.Weather Facsimile (WEFAX) data are transmitted between theCDA and various small users at S-Band. A Search andRescue (SAR) system receives distress signals at UHF andretransmits the signals to SARSAT ground stations at L-Band.In addition to the telemetry link, GOES-X uses a Multiuse/DataLink (MDL), for transmission of diagnostic data for ImageNavigation and Registration. The system has been improvedover previous GOES systems in that the imager and sounderequipment of the VAS are separate and independentlyoperated. The imager allows simultaneous imaging from visibleand infrared channels, has increased sensitivity, and provideshigher resolution (4 km) data in the cloud detection and surfacechannels. The sounder is improved because of additionalspectral channels, higher resolution (8 km) and increasedsensitivity. The scan control of both parts is more flexible,providing small area coverage for frequent severe stormobservations. Image navigation utilizes Image MotionCompensation and Mirror Rotation Compensation so imagerycan be accurately registered with respect to a fixed grid thatcan remain unchanged for one to several days.

Description
Gorizont 23 was a Soviet geosynchronous communicationssatellite. It was launched to provide telephone, telegraph andfax communications services, in addition to relaying TV andradio broadcasts. It was stationed at 103 deg E.
The Gorizont spacecraft possessed an initial mass in excess of2.1 metric tons and have demonstrated a lifetime of nearly 10years, although a 5-year service life was more common. The3-axis stabilized satellite was approximately 2 m in diameterand 5 m long with two large solar arrays capable of generating1.3 kW of electrical power for the first 3 years. Seven separatetransmission antennas allowed a variety of reception patternsfor both broad and localized terrestrial regions.
A typical Gorizont communications payload included sixgeneral purpose (TV, audio, facsimile) 6/4 GHz transponders(five 12.5 W and one 60 W), one Luch 14/11 GHz transponder(15 W), and one Volna 1.6/1.5 GHz transponder (20 W). TheVolna transponders were INMARSAT-compatible and wereextensively used by the Russian merchant marine fleet via theprimary GEO television rebroadcasting system, supporting allfive Federation time zones: Zone 1 from 140 deg E, Zone 2from 90 deg E, Zone 3 from 80 deg E, Zone 4 from 53 deg E,and Zone 5 from 14 deg W. These transmissions were handledby Orbita (12-m receiving antenna) and Moskva (2.5-mreceiving antenna) ground stations in the 6/4 GHz band. TheMoskva Globalnaya system was inaugurated in 1989 using 4-m receiving antennas and serviced by Gorizonts at 96.5 deg Eand 11 deg W.

Description
Informator was a prototype satellite for the Koskon (SpaceConversion) Global Space Communication Systems. It waslaunched from the Plesetsk cosmodrome by a Kosmos launchvehicle. The 600 kg satellite was inserted into an orbit of 960km by 1,010 km at an inclination of 83 degrees under thesponsorship of the Ministry of Geology. It was developed bythe Polet Production Association and the Elas ScientificProduction Association and was cylindrical in nature (1.8 m indiameter, 4 m in height) with two solar panels designed toproduce 1kW average power. Like Gonets, Informator 1 reliedon gravity gradient stabilization as was projected to have anoperational lifetime of 5 years or more. It also carried theSoviet RS14 and the German RUDAK 2 amateur satellitetransponders as piggy-back payloads. Exactly one week afterthe launch of these amsat transponders, two more, RS12 andRS13, were placed in a virtually identical orbit as secondarypayloads to the Kosmos 2123 navigation satellite.

Description
Inmarsat 2-F2 was a maritime satellite launched using a Deltalaunch vehicle from Cape Canaveral Air Force Base for theInternational Maritime Satellite Organization. It operated a totalof four INMARSAT-2 satellites. Launched between 1990-92,they each had a capacity equivalent to about 250 INMARSAT-A voice circuits.
The spacecraft was built by an international consortiumheaded by British Aerospace. Subcontractors included HughesAircraft Company, Fokker (The Netherlands), Matra (France),MBB (Germany), NEC (Japan), and Spar (Canada). Satelliteground control operations contractors included CLTC (China),CNES (France), SED (Canada), Telespazio (Italy) and Intelsat.
The INMARSAT-2s were three-axis-stabilized spacecraftbased on the Matra/B Ae Eurostar platform. With a ten-yeardesign life, each satellite has a 1,300 kg launch mass,reducing to an initial 800 kg in orbit. Initial power rating was1,200 W.
The communications payload comprised two transponderssupporting satellite- to-mobile (service) links in L-band(1.6GHz uplink, 1.5GHz downlink) and satellite-to-earth station(feeder) links in C-band (6.4GHz uplink, 3.6GHz downlink).Effective L-band isotropic radiated power (EIRP) was 39dBW.Each satellite's global beam covered roughly one-third of theearth's surface.
INMARSAT 2 F2 is now being used as a spare back-up toINMARSAT 3 F4 in the Atlantic Ocean Region.

Description
Italy's first national communications satellite, ITALSAT 1 wasdual launched aboard an Ariane 44L booster from Kourou,French Guiana. Placed in geosynchronous orbit above 13.2deg. e, the satellite served as a spaceborne telephoneswitchboard, redirecting up to 12,000 calls at once. ITALSATwas experimental in nature, a pre-operational component of aproposed digital satellite network for Italy. Built by SeleniaSpazio for Agenzia Spaziale Italiana (the Italian SpaceAgency), ITALSAT 1 was box-shaped, measuring 2.72 by 2.22by 3.48 m. It was 6.1 m tall with its two 2-m reflector antennasdeployed. Solar arrays spanned 21 m and provided 1,600 Wof power. Its communications package housed six 20/30 GHzmultibeam transponders, three 20/30 GHz global beamtransponders and a propagation experiment operating at 40/50GHz. The multibeam system, using advanced time divisionmultiple access (TDMA) techniques, was expected to undergotwo years of testing; the global beam system was consideredoperational from the start and was used to test new services.ITALSAT 1 had a 5-year design life, but the accuracy of itsorbital insertion saved maneuvering fuel, giving it a predicted 2-year life extension.

Description
The Meteor-3 series of meteorological satellites providedtwice-daily weather information including data on clouds, iceand snow cover, atmospheric radiation and humidity sounding.The Meteor-3 class of satellites orbited in a higher altitude thanthe Meteor-2 class of satellites and thus provided morecomplete coverage of the Earth's surface. The Meteor-3 hadthe same payload as the Meteor-2 but also included anadvanced scanning radiometer with better spectral and spatialresolution and a spectrometer for determining total ozonecontent. The spacecraft incorporated three-axis stabilization(0.5 deg accuracy) and twin 10-m span solar panels. The orbitwas adjusted by ion thrusters. Meteorological data wastransmitted to four primary sites in the former Soviet Union inconjunction with about 80 other smaller sites. Internationallycompatible Automatic Picture Transmission (APT) was madeavailable on 137 - 138 MHz channels to ground workstations.The Meteor-3 had two 0.5 - 0.7 micron radiometers. The firstprovided direct relay with a swath width of 2600 km and aresolution of 1 x 2 km. The second stored data on an on-boarddata recorder which provided global coverage with a swathwidth of 3100 km and a resolution of 0.7 x 1.4 km. The payloadalso included a scanning IR radiometer at 10.5 - 12.5 micronswith a swath width of 3100 km and a resolution of 3 x 3 km,and an 8-channel IR radiometer for atmospheric sounding at9.65 - 18.7 microns with a swath width of 2000 km and aresolution of 32 x 32 km.

Description
The objective of this cooperative space mission between theUS and the former USSR was to map global ozone from spacewith the goal of studying global and regional changes in theozone. The Meteor-3, a series of meteorological observationspacecraft, had a three-axis stabilized system to provide anadir-pointing fixed-yaw attitude. The attitude system consistedof a combination of gyros and a horizon sensor similar to USsatellites. Attitude was controlled by momentum wheels. Solarenergy was collected by twin solar panels and electrical powerwas provided by solar-charged nickel-cadmium batteries. TheMeteor-3 normal instrumentation included twin TV camera formonitoring earth cloud cover and ice conditions, an infraredradiometer (IRR) for determining sea-surface temperature andobtaining cloud information, and a multichannel spectrometer(MCS) for providing thermal atmospheric sounding data. TheMeteor 3-5 spacecraft incorporated a Total Ozone MappingSpectrometer (TOMS), designed and operated by NASA, asthe first foreign sensor to fly on the Meteor series. The Meteor-3 had a continuous telemetry format, and a 24-hour storagecapacity on board for the TOMS operation. With a downlinkdata rate of 80 kbs, observational data were downlinked toreceiving stations in both the US and the Russia.

Description
Microsat 1 was launched using a Pegasus booster rocket. Thepayload was delivered to orbit by vehicle released from a B-52.About an hour after take off from Edwards AFB, the 15-m long,1.2-m-diameter 19,026-kg Pegasus was dropped from theaircraft and its engines ignited. A stage separation malfunction,however, cast the 7-satellite payload into a lower thananticipated orbit. Ground controllers could not make contactwith the satellites and it appeared that they were lost. Some 9hours after launch, telemetry was acquired as the Microsatspassed over the main control station. Apparently, a new fourthstage guidance system compensated for the separation glitchand modified the trajectory. Subsequent passes verified that all7 satellite were operating. Built by Defense Systems Inc. forthe Defense Advanced Research Projects Agency (DARPA),the 12-sided Microsats measured 10 cm by 48 cm andweighed 22 kg each. They were designed to assess the use oflow-earth orbit for global communications. Each satelliteoperated in UHF, using an analog transponder for FM radiorelay of voice communications and a digital transponder torelay data, message, facsimile and modest video traffic.Although the 359 by 457-km orbit fell short of the planned 719km, the inclination was on target, allowing mission objectivesto be met.

Description
Molniya 1/80 was a first-generation Russian communicationssatellite (COMSAT) orbited to test and perfect a system ofradio communications and television broadcasting using earthsatellites as active transponders and to experiment with thesystem in practical use. The basic function of the satellite wasto relay television programs and long-distance two-waymultichannel telephone, phototelephone, and telegraph linksfrom Moscow to the various standard ground receiving stationsin the 'Orbita' system. The satellite was in the form of ahermetically sealed cylinder with conical ends -- one endcontained the orbital correcting engine and a system ofmicrojets, and the other end contained externally mountedsolar and earth sensors. Inside the cylinder were (1) a high-sensitivity receiver and three 800-MHz 40-w transmitters (oneoperational and two in reserve), (2) telemetering devices thatmonitored equipment operation, (3) chemical batteries thatwere constantly recharged by solar cells, and (4) an electroniccomputer that controlled all equipment on board. Mountedaround the central cylinder were six large solar battery panelsand two directional, high-gain parabolic aerials, 180 deg apart.One of the aerials was directed continually toward the earth bythe highly sensitive earth sensors. The second aerial was heldin reserve. Signals were transmitted in a fairly narrow beamensuring a strong reception at the earth's surface. The satellitereceived telemetry at 1000 MHz. Television service wasprovided in a frequency range of 3.4 to 4.1 GHz at 40 w.Molniya 1/80, whose cylindrical body was 3.4 m long and 1.6 min diameter, was much heavier than corresponding U.S.COMSATs, and it had about 10 times the power output of theEarly Bird COMSAT. In addition, it did not employ ageosynchronous equatorial orbit as have most U.S. COMSATsbecause such an orbit would not provide coverage for areasnorth of 70 deg n latitude. Instead, the satellite was boostedfrom a low-altitude parking orbit into a highly elliptical orbit withtwo high apogees daily over the northern hemisphere -- oneover Russia and one over North America -- and relatively lowperigees over the southern hemisphere. During its apogee,Molniya 1/80 remained relatively stationary with respect to theearth below for nearly 8 of every 12 hr. By placing three ofmore Molniya 1 satellites in this type of orbit, spacing themsuitably, and shifting their orbital planes relative to each otherby 120 deg, a 24-hr/day communication system could beobtained.

Description
The Meteosat Operational Programme (MOP-2) satellite wasthe second operational geostationary Meteosat satellitefollowing 3 pre-operational Meteosat satellites (Meteosat-1,-2,-3/P2). The primary goals of the MOP satellites were (1) toprovide visible and IR day/night cloudcover data and radiancesand (2) to disseminate image data to users through the DataCollection Platform (DCP). MOP-2 (or Meteosat 5) was a 2.1 mdiameter, 3.195 m high stepped cylindrical body with solarcells on six main body panels. The spacecraft was spin-stabilized at 100 rpm around the main axis aligned almostparallel to the Earth's axis with spin regulated by two smallhydrazine thrusters. Spin access control and east-weststationkeeping were provided by two pairs of large thrusters.Attitude information was provided by Earth horizon and Sun-litsensors. A radiating dipole antenna directed S-band (333 kbs)transmission of DCP image data to the Data Acquisition,Telemetry, and Tracking Station at Odenwald, Germany forrelay to the Meteosat Ground Computer System and MeteosatOperations Control center at ESA's European SpaceOperations Center (ESOC). The MOP-2 carried a singleimaging radiometer in visible/infrared wavelengths in additionto the Data Collection Platform.

Description
Global Positioning System (GPS) was developed by the USDepartment of Defense to provide all-weather round-the-clocknavigation capabilities for military ground, sea, and air forces.Since its implementation, GPS has also become an integralasset in numerous civilian applications and industries aroundthe globe, including recreational used (e.g., boating, aircraft,hiking), corporate vehicle fleet tracking, and surveying. GPSemploys 24 spacecraft in 20,200 km circular orbits inclined at55 degrees. These vehicles are placed in 6 orbit planes withfour operational satellites in each plane.
GPS Block 2 was the operational system, following thedemonstration system comprised of Block 1 (Navstar 1 - 11)spacecraft. These spacecraft were 3-axis stabilized, nadirpointing using reaction wheels. Dual solar arrays supplied 710watts of power. They used S-band (SGLS) communications forcontrol and telemetry and UHF cross-link between spacecraft.The payload consisted of two L-band navigation signals at1575.42 MHz (L1) and 1227.60 MHz (L2). Each spacecraftcarried 2 rubidium and 2 cesium clocks and nuclear detonationdetection sensors. Built by Rockwell Space Systems for theUS Air Force, the spacecraft measured 5.3 m across with solarpanels deployed and had a design life of 7.5 years.

Description
NOAA-12 (NOAA-D before launch) is a third-generationoperational meteorological satellite for use in the NationalEnvironmental Satellite, Data, and Information Service(NESDIS). The satellite design provides an economical andstable sun-synchronous (morning equator-crossing) platformfor advanced operational instruments to measure the earth'satmosphere, its surface and cloud cover, and the near-spaceenvironment. Primary sensors include an Advanced Very HighResolution Radiometer (AVHRR) for observing daytime andnighttime global radiances and temperatures and a TIROSOperational Vertical Sounder (TOVS) for obtaining temperatureand water vapor profiles through the earth's atmosphere.Secondary experiments consist of a Space EnvironmentMonitor (SEM), which measures the proton and electron fluxesnear the earth, and an ARGOS Data Collection and LocationSystem, which processes and relays to central data acquisitionstations the various meteorological data received from free-floating balloons and ocean buoys distributed around theglobe. The satellite is based upon the Block 5D spacecraft busdeveloped for the U.S. Air Force, and it is capable ofmaintaining an earth-pointing accuracy of better than plus orminus 0.1 deg with a motion rate of less than 0.035 deg/s.NOAA 12 operations were closed as of April 2001.

Description
This US Navy Ocean Surveillance Satellite (NOSS) waslaunched from Vandenberg AFB aboard a Titan 4 rocket. Itplaced a cluster of one primary satellite and three smaller sub-satellites (that trailed along at distances of several hundredkilometers) into low polar orbit. This satellite array determinedthe location of radio and radars transmitters, usingtriangulation, and the identity of naval units, by analysis of theoperating frequencies and transmission patterns.
In external appearance, the sub-satellites were reminiscent ofthe Navy's Transit navigational satellites. The had gravitygradient orientation booms 10-15 meters long. These ensuredthat the side of the satellite body where the signal antennaswere mounted was constantly oriented toward the Earth. Thesatellites maintained an assigned position in a group atdistances of 30 to 240 km one from the other by using on-board low-thrust engines. As a result of ground processing ofdirection-finding data on the signals from target emittersprovided by a group of satellites, and also sequentially byseveral groups of satellites, the coordinates, direction andspeed of travel were obtained.

Description
The Okean series of satellites are all-weather radaroceanographic systems primarily designed to monitor sea-iceconditions in the Arctic Seas. The payload includes a side-looking radar, a scanning microwave radiometer, nadir-viewingmicrowave spectrometer, optical scanners and a datacollection platform. The spacecraft is a stepped cylindricalpressurized bus 3 m high and 1.4 m diameter. The spacecraftis 3-axis stabilized (nadir pointing, aided by a gravity gradientboom), has twin solar arrays spanning 4.82 m and an 11.8 mradar antenna mounted on the Earth-facing base. A primaryfeature of the Okean-series is direct Automatic PictureTransmission (APT) on 137.4 MHz of imagery to APT stationsas well as to foreign users. The on-board recorder has 6.5minute capacity and permits coverage and transmission of a470 x 2750 km image by side-looking radar (SLR) and 1930 x2750 km image by the multispectral scanner during a pass overan APT station. The Okean payload was flown on Cosmos1500, Cosmos 1602, Cosmos 1766, and Cosmos 1869 (radarfailed), as well as Okean-1 and Okean-2.

Description
ORBCOMM-X was launched from the Kourou Space Center inFrench Guiana on the same Ariane rocket with UOSAT 5,TUBSAT, and SARA. Built by Orbital Sciences Corporation, itwas a forerunner of a proposed network of low-earth-orbitingmobile communications satellites. The 0.46 by 0.66 by 0.2-morbiter was powered by body mounted solar cells generating27 W. It was flown to evaluate the ORBCOMMcommunications system, explore possible store and forwardservices and test location determination capability. Initialground contact with ORBCOMM-X indicated the satellite washealthy, but communications were lost following a scheduledshut down of the VHF transmitter.

Description
This Chinese domestic communications satellite was strandedin an unusable orbit when the CZ-3 launch vehicle's third stagefailed 135 seconds after ignition. The satellite was placed intoa satisfactory parking orbit; the subsequent boost to transferorbit failed. The following day, the satellite's apogee kick motorraised its flight path, allowing it to perform limitedcommunications work from a highly elliptical orbit. ShiyongTongbu Weixing, or Operational GeostationaryCommunications Satellite, was part of the Chinese Dong FangHong 2 series. It was cylindrical, measuring about 2 m indiameter and 2.4 m high. The third stage failure was notexpected to affect the scheduled 1992 launches of 2 Australianpayloads.

Description
The Resurs-F was a photoreconnaissance spacecraft used tomonitor Earth's natural resources (primarily those of theUSSR). The spacecraft flew two types of missionconfigurations: (1) F1, which typically lasted two weeks andused three Kate-200 and two KFA-1000 camera systems, and(2) F2, which flew in a lower orbit than F1, typically lasted 3-4weeks, and used the MK-4 camera system. The MK-4 was amultispectral visible wavelength camera which provided 5 to 8meter resolution. The MK-4 operated at six wavelengths:0.635-0.69, 0.81-0.9, 0.515-0.565, 0.46-0.505, 0.58-0.8, and0.4-0.7 micrometers. The Kate-200 was a 200 mm focal lengthcamera which operated at three wavelengths (0.5-0.6, 0.6-0.70.7-0.85 micrometers) with a resolution of 15 to 30 m. TheKFA-1000 was a 1000 mm focal length camera with twowavelengths (0.57-0.68 and 0.67-0.81 micrometers) at 2 to 5m resolution. The film camera systems were returned in 2.321diameter spherical descent capsules, which were re-usedapproximately three times. The F2 mission was supported bysolar panels which backed up the standard battery powersupply. A stellar camera was provided on each mission forpointing. The data will be available in the U.S. through CentralTrading Systems of Fort Worth, TX.

Description
The main objective of the Space Optical Telescope (SOT) is toachieve the high spatial resolution required for thedetermination of density, temperature, magnetic field, and non-thermal velocity field in solar features on the scale at whichmany basic physical processes occur. Such processes includechanges in magnetic field strength, waves, single pulses, andsystematic mass flows. To understand the flow of energy andmass on a global scale over the surface of the sun, it isnecessary to investigate structures only slightly larger than thephoton mean free path. SOT consists of two major parts: thetelescope facility, which remains essentially unchanged frommission to mission; and the scientific instruments (SIs) which,depending upon the objectives, may vary from mission tomission. The telescope uses an on-axis Gregorianconfiguration with primary mirror 1.3 m in diameter. Theparaboloidal primary mirror focuses light through a hole in aheat-rejection mirror allowing only 3 arc-min of the sun's 32-arc-min disk to be seen by the secondary mirror. Theellipsoidal secondary mirror reflects the image onto a flattertiary mirror that directs the light beam off axis. Focal planeinstruments, such as those selected for the SOT-1 mission, arepositioned at the final or Gregorian focus. The telescope facilityhas an effective focal length of 31.25 m and a 151-micrometerarc-s plate scale. The SOT Observatory remains Shuttle-attached throughout the mission. It utilizes the Spacelab-provided instrument pointing system during on-orbitoperations, and is mounted via launch locks directly to theShuttle cargo bay during launch and landing. Missionoperations are conducted by dual interactive control, eitherfrom the payload specialist station in the Shuttle aft flight deckor from ground-based stations in the payload operationscontrol center.

Description
British cosmonaut Helen Sharman joined Anatoli Artsebarskiand Sergei Krikalev aboard Soyuz TM-12. She became thefirst woman to visit the Mir space station and conductedmedical experiments on behalf of her Soviet hosts. She alsotook pictures and made radio contact with Britishschoolchildren. Her 7-day, 21-hr, 14-mn mission ended May26, when she returned to earth with the TM-11 crew.Artsebarski and Krikalev settled into the Mir regimen ofexeriments and maintenance. An atmosphereic researchsubsatellite released June 17 failed when its antenna did notdeploy. A balloon deployment on August 15 also failed. During6 EVAs, taking place between June 25 and July 27, thecosmonauts installed outdoor experiments, retrieved others,repaired the Kvant docking antenna and erected a 14-mplatform to host an attitude control thruster for the growingstation. Total time outside Mir was 31 hrs, 58 mns. WhileArtsebarski and Krikalev orbited earth, their homeland suffereda failed coup d'etat and political turmoil that would lead to thebreakup of the Soviet Union. Mir activities, however, proceedednormally; Progress M-9 was launched on schedule on August20th. The cosmonauts were more affected by a decision madea month earlier to combine two upcoming Mir flights into one.The shuffle bumped Krikalev's replacement, requiring him tospend 5 more months in space. Soyuz TM-13, bringingArtsebarski's relief, arrived October 4. He returned to earthOctober 10 after 144 days, 15 hrs, 22 mns in space.

Description
A crew representing Austria, the Republic of Kazakhstan, andthe Soviet states, was lofted to Mir aboard Soyuz TM-13.Austrian Franz Viehbock and Kazakh Toktar Aubakirov werepaying passengers. Aubakirov, from the home of the Tyuratamlaunch site, was the first commercial cosmonaut from insidethe USSR. Commander Aleksander Volkov, a Ukranian livingin Moscow, would reside on Mir for the next few months.Viehbock and Aubakirov spent their 6-day visit completing arigorous slate of medical, biological and technical experiments.Each also made photo surveys of their respective lands. Theresearchers returned to earth October 10, joining AnatoliArtsebarski aboard Soyuz TM-12. Both had logged 7 days, 22hrs, 13 mns in space. Volkov remained at Mir with veteranSergei Krikalev. On October 15, the team tested the Kvant portdocking antenna during a 1-hr, 44-mn flight around the stationaboard TM-13. Progress M-10 arrived October 21, docking twodays after an initial rendezvous was aborted by a computermalfunction. In contrast to the daily upheavals that wereshattering the Soviet Union, the Mir flight remained markedlyroutine. The cosmonauts devoted their working hours toastrophysical and geophysical experiments, medical studiesand smelting operations.

Description
STS-37 was the eighth flight of the shuttle Atlantis and the39th shuttle flight. The orbiter weighed 115,502 kg at launch;total vehicle weight was 2,047,178 kg. Much of the load wasthe Gamma Ray Observatory (GRO), at 15, 620 kg theheaviest shuttle-launched payload to date. STS 37 was staffedby Commander Steven R. Nagel, Pilot Kenneth D. Cameron,Mission Specialists Linda M. Godwin, Jerry L. Ross and JayApt. GRO deployment was scheduled from mission day three;an EVA to test conveyance carts and construction aids forlarge space structures was on the docket for day four. As ithappened, GRO deployment was delayed and the firstspacewalk since 1985 commenced a day early. Plans werechanged by a stubborn antenna. Midway though GRO'sdeployment sequence, while still attached to the remotemanipulator arm, the satellite's high gain antenna boom stuckin its stowed position. Repeated maneuvers to free it failed.Astronauts Ross and Apt were called on to free the boom byhand. Seventeen minutes after the pair exited Atlantis, Rossreleased the boom. GRO was ultimately cast into orbit only 4.5hr later than planned. While outside the shuttle, Ross and Aptbegan the scheduled equipment tests, evaluating hand railsand foot restrains. They reentered the shuttle after 4 hrs, 38mns. Outdoor activities resumed the next day, with the teamtesting manual and electric personnel carts during a 6-hr, 11-mn EVA. Several times during the flight, Atlantis passed withinview of the Mir station. The crew attempted to contact theirSoviet conterparts via ham radio, but were unsuccessful.Landing was delayed one day by gusty winds at Edwards AFB.The 5-day, 23-hr, 33-mn mission concluded on Edward'srunway 33 at 13:55, April 11.

Description
STS-39 was the 12th shuttle Discovery flight and the firstunclassified military mission. The purpose of the flight was togather data needed to develop spaceborne sensors andsoftware that could recognize missile or reentry vehiclesignatures as they flew through or above the atmosphere. Tothat end, Discovery carried Air Force and Strategic DefenseInitiative-sponsored instruments to observe gases in the upperatmosphere, emissions from the shuttle engines, andchemicals released from co-orbiting subsatellites. Thescheduled observations required the crew to work around theclock in 12-hour shifts. Mission Commander was Michael L.Coats, the Pilot was Blaine Hammond Jr., and MissionSpecialists were Gregory L. Harbaugh, Donald R. McMonagle,Guion S. Buford, C. Lacy Veach and Richard J. Hieb. Theprimary Air Force payload -- a CIRRIS infrared telescope,secondary sensors and an ultraviolet camera -- was activated3 hours into the flight. Two failed tape recorders curtailed datacollection until the crew rigged a bypass on mission day 7. TheInfrared Background Signature Survey (IBSS) instrument,mounted on the Shuttle Pallet Satellite (SPAS), was deployedon May 1. A pointing error stalled the experiment for 9 hours.With IBSS/SPAS in position, the shuttle undertook a series offast Orbital Maneuvering System (OMS) and Reaction ControlSystem (RCS) burns. During the 27-mn sequence, and 3encores, the IBSS photographed Discovery's exhaust plumes.The free-flyer subsequently observed chemicals released fromthree subsatellites ejected from the cargo bay. A fifth satellitewas deployed several hours before landing. Discovery's returnto earth was rerouted to KSC due to high winds at EdwardsAFB. It touched down on the concrete runway at 18:55 May 6,after 8 days, 7 hrs, 22 mns in orbit. Despite the technicalproblems, the returns from STS 39 surpassed expectationsand will serve as a database for missile defense systemdevelopment.

Description
The first shuttle mission dedicated to life sciences began at13:25, June 5, when Columbia lifted off from the KennedySpace Center Pad 39B. The orbiter also carried 12 Get AwaySpecials and 7 NASA Orbiter Experiments. The crew itself wasthe focal point for the Spacelab Life Science (SLS-1) researchto determine the causes of space sickness and note physicalchanges in microgravity conditions. The crew consisted ofCommander Bryan D. O'Connor, Pilot Sidney M. Gutierrez,Mission Specialists James P. Bagian, Tamara E. Jernigan,Margaret R. Seddon, and Payload Specialists F. Drew Gaffneyand Millie Highes-Fulford. The human crew was accompaniedby 29 white rats and 2,500 jellyfish. The astronauts entered theSpacelab module 3 hrs, 44 mns into the flight, kicking off arigorous work schedule in which they poked, prodded, spun,weighed, sampled, squeezed and monitored. It was the mostconcentrated life science research conducted in orbit sinceSkylab; the crew achieved 140% of mission goals. On flightday 2, concern was raised that torn insulation in the cargo baymight prevent the doors from closing. That unease wasdispelled and a proposed spacewalk to make repairs was notneeded. The 9-day, 2-hr, 14-mn mission ended on EdwardsAFB runway 22 at 15:39, June 14.

Description
TDRS-E was the fourth successful launch of the Tracking andData Relay Satellite series. TDRS-E was used in combinationwith other TDRS spacecraft and a ground communicationssystem to form the Tracking and Data Relay Satellite System(TDRSS).
The objective of the TDRSS program is to provide andmaintain improved tracking and data acquisition services tospacecraft in low-Earth orbit. In order to fulfill this objective,TDRSS requires at least two fully operational TDRS in orbitwith one or more additional spacecraft serving as systemspares.
Each TDRS is a three-axis, momentum-biased satellite. Thebus section of the spacecraft is hexagonal with an approximatediameter of 3 m. Power is provided by two opposing, three-section solar array panels, 4.0 x 3.8 m in dimension, at the endof 3.25 m booms. Perpendicular to the solar arrays are the two4.9 m diameter, K- and S-band, single-access (SA) antennae.With the solar panels and SA antennae deployed, TDRSmeasures 17.3 x 14.2 m.
TDRS is comprised of three functional modules: payload,spacecraft, and antenna. The payload module consists of twosingle-access compartments, the multiple access antennaplatform, and a main payload module. The main payloadmodule has six panels which form an integral part of the mainbus structure and house the principle elements of the TDRSpayload. The spacecraft module contains the thermal control,electrical power, attitude control, propulsion, and tracking,telemetry, and command systems. The antenna moduleconsists of the two SA dish antennae, the 2.0 m K-bandSpace-to-Ground Link (SGL) antenna, and, on the bus of thespacecraft, the 30 helical element, multiple access (MA)antenna array, a C-band antenna, and an S-bandomnidirectional SGL antenna.
In addition to changes made to previous TDRS spacecraftsubsequent to TDRS-A, TDRS-E was modified to providemultiple fusing of critical coaxial and waveguide switches ineach single access compartment as a result of on-orbitexperience with TDRS-C.

Description
The Upper Atmosphere Research Satellite (UARS), an elementin NASA's Mission to Planet Earth, was launched from theShuttle (STS 48) to provide data for better understanding ofthe Earth's upper atmosphere and the effects of natural andhuman interactions on the atmosphere. The objectives of theUARS mission were to conduct research in the atmosphereabove the tropopause by measuring the global budget ofconstituent trace gases and their chemical, dynamic,andradiative behavior.
UARS had two major components: an instrument modulecontaining the ten instruments and mission uniquecomponents, and a multimission modular spacecraft (MMS).The MMS included the Communications and Data Handling(C&DH) subsystem, the Modular Attitude Control Subsystem(MACS), the Modular Power Subsystem (MPS), the SignalConditioning and Control Unit (SC&CU), and the PropulsionModule. The C&DH provided communications, command andcontrol of the spacecraft and instruments, acquistion andstorage of science and housekeeping data, and centralcomputation facilities. The MACS provided attitudedetermination and control. The MACS subsystem maintainedthe Earth-oriented three-axis stability of the spacecraft throughthe use of star trackers, an inertial reference unit, three-axismagnetometers, a Fine Sun Sensor assembly, an EarthSensor Assembly, and a Coarse Sun Sensor assembly, aswell as momentum wheels, magnetic torquers, and attitudecontrol thrusters.
Power was maintained by a six-panel solar array and three 50A-hour batteries. The power subsystem also consisted of theMPS, regulators, solar array drive (which had some problemsduring summer 1992), solar array drive electronics, and powertransfer assemblies.
The instrument complement for UARS consisted of nineinstruments devoted to the primary atmospheric mission plusone announcement-of-opportunity instrument, the ActiveCavity Radiometer Irradiance Monitor II (ACRIM II). The nineprimary instruments were: (1) Cryogenic Limb Array EtalonSpectrometer (CLAES); (2) Improved Stratospheric andMesospheric Sounder (ISAMS); (3) Microwave Limb Sounder(MLS); (4) Halogen Occultation Experiment (HALOE); (5) HighResolution Doppler Imager (HRDI); (6) Wind ImagingInterferometer (WINDII); (7) Solar Ultraviolet SpectralIrradiance (SUSIM); (8) Solar Stellar Irradiance ComparisonExperiment (SOLSTICE); and, (9) Particle EnvironmentMonitor (PEM). There were also ten UARS investigatorsperforming theoretical investigations.

Description
This US Navy Ocean Surveillance Satellite (NOSS) waslaunched from Vandenberg AFB aboard a Titan 4 rocket. Itplaced a cluster of one primary satellite and three smaller sub-satellites (that trailed along at distances of several hundredkilometers) into low polar orbit. This satellite array determinedthe location of radio and radars transmitters, usingtriangulation, and the identity of naval units, by analysis of theoperating frequencies and transmission patterns.
In external appearance, the sub-satellites were reminiscent ofthe Navy's Transit navigational satellites. The had gravitygradient orientation booms 10-15 meters long. These ensuredthat the side of the satellite body where the signal antennaswere mounted was constantly oriented toward the Earth. Thesatellites maintained an assigned position in a group atdistances of 30 to 240 km one from the other by using on-board low-thrust engines. As a result of ground processing ofdirection-finding data on the signals from target emittersprovided by a group of satellites, and also sequentially byseveral groups of satellites, the coordinates, direction andspeed of travel were obtained.

Description
This spacecraft is part of a continuing series of classifiedspacecraft. The three spacecraft USA 39 (1989-046A), USA 65(1990-095A), and USA 75 (1991-080B) replace an earlierconstellation of geosynchronous orbit spacecraft. These threewere positioned at longitudes of approximately 195, 8, and 72degrees, respectively, as of February 20, 1992. Eachspacecraft carries two instruments whose data are availablefor magnetospheric research: the Magnetospheric PlasmaAnalyzer (MPA) and the Synchronous Orbit Particle Analyzer(SOPA). The article by McComas et al., "Magnetosphericplasma analyzer: Initial three-spacecraft observations fromgeosynchronous orbit,'' (J. Geophys. Res., 98, No. A8, p.13453, 1993) gives more information. It also declares:"Recently, the MPA and SOPA data sets have become part ofthe International Solar Terrestrial Physics (ISTP) program withthe inclusion of key parameter data in the ISTP Central DataHandling Facility (CDHF). These data should provide avaluable adjunct to ISTP science, particularly in light of thelack of a dedicated `Equator' spacecraft, in addition toproviding new information about the geosynchronousenvironment in their own right.''

Description
The objective of Yohkoh (Japanese for sunbeam) is to studythe high-energy radiations from solar flares (hard and soft X-rays and energetic neutrons) as well as quiet structures andpre-flare conditions. The mission is a successor to Hinotori, aprevious Japanese spacecraft flown at the previous solaractivity maximum in 1981.
Yohkoh is a three-axis stabilized observatory-type satellite in anearly-circular Earth orbit, carrying four instruments: twoimagers and two spectrometers. The spacecraft is arectangular solid about 2 m square and 4 m long. The imaginginstruments have almost full-Sun fields of view, to avoidmissing any flares on the visible disk of the Sun. The hard X-ray telescope is a multi-grid synthesis type with a spatialresolution of 7 arcsec, operating in the 20 - 80 keV range. Thesoft X-ray telescope uses grazing-incidence optics andachieves 4 arcsec spatial resolution, operating in the 0.1 - 4keV range and using 1024 x 1024-pixel CCDs. US solarphysicists at Lockheed Palo Alto Research Laboratory arecollaborating in the soft X-ray telescope production and dataanalysis. There is also a continuum spectrometer for X-raysand gamma-rays from 3 keV to 20 MeV (also sensitive toneutrons) and a Bragg crystal spectrometer for the X-ray linesFe XXV, Fe XXVI, Ca XIX, and S XV.
Approximately 50 MB of data are accumulated per day, andstored on an on-board tape recorder with 10.5 Mbyte capacity.The Yohkoh mission is a cooperative mission of Japan, theUS, and the United Kingdom.
The Solar Data Analysis Center (SDAC) at NASA/GSFC canprovide small quantities of data, by request [email protected]. Sample data from the SXTimages may be obtained via the World Wide Web from theSDAC at:
