Crew: Brown, Curbeam, Davis, Robinson, Rominger, Tryggvason. Deployed and retrieved the CRISTA-SPAS-2 (the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2) designed to study Earth's middle atmosphere.

Deployed and retrieved the CRISTA-SPAS-2 (the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2) designed to study Earth's middle atmosphere. The CRISTA-SPAS-2 was making its second flight on the Space Shuttle and represented the fourth mission in a cooperative venture between the German Space Agency (DARA) and NASA.

CRISTA-SPAS was deployed by the RMS arm at 22:27 GMT on August 7 and was recaptured by Discovery's RMS arm at 15:14 GMT on August 16. Because of unfavorable weather conditions at the primary shuttle landing site at the Kennedy Space Center, Discovery was waved off for its scheduled August 18 landing. STS-85 landed the next day, at Kennedy Space Center at 11:08 GMT.

Cargo Bay Payloads:

  • Bay 1-2: External Airlock
  • Bay 5: MPESS (Multi Purpose Experiment Support Structure) with the MFD (Manipulator Flight Demonstration) payload from the Japanese space agency. This was a 'robot hand' that will be at the end of the robot arm being developed for the Japanese space station module.
  • Bay 6 Port sidewall: A small carrier with the ITEPC radiation dose counter.
  • Bay 7: MPESS with the TAS-01 payload (Technology Applications and Science) from NASA-Goddard's Hitchhiker-M program. TAS-01 consisted of several GAS cans with science experiments, including the second flight of the Shuttle Laser Altimeter and an instrument to measure the absolute bolometric flux of the Sun.
  • Bay 9: ASTRO-SPAS, a free flying platform built by Germany's DASA, carrying the CRISTA-SPAS atmospheric science payload on its second mission.
  • Bay 11 Port sidewall: a small carrier with the ERPCL transmitter/receiver which communicates with SPAS during its flight.
  • Bay 12: MPESS with the IEH-2 Hitchhiker payload from Goddard. The International Extreme Ultraviolet Hitchhiker was a joint NASA-Italian astronomy payload. Its two main instruments were the UVSTAR ultraviolet spectrograph and the SEH solar extreme ultraviolet instrument. The MPESS also carried the GLO-5 and GLO-6 airglow studies and the Data-Chaser technology experiment. UVSTAR's main objective is to study the extreme UV emissions from the Io plasma torus around Jupiter.
  • Bay 13 Starboard sidewall: GABA (GAS Beam Adapter) with two GAS experiment cans, G-572 and G-745. G-572 has experiments from Bellermine College and Utah State, and G-745 has student experiments from Mayo High School.

Landing:

August 19, 1997, 7:07:59 a.m. EDT, Runway 33, Kennedy Space Center, Fla. Rollout distance: 8,792 feet (2,680 meters). Rollout time: One minute, eight seconds. Mission duration: 11 days, 20 hours, 26 minutes, 59 seconds. Landed on revolution 190. Landing opportunity Aug. 18 waved off due to threat of ground fog in local area.

Mission Highlights:

STS-85 carried a complement of payloads in the cargo bay that focused on Mission to Planet Earth objectives as well as preparations for International Space Station assembly: the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere- Shuttle Pallet Satellite-2 (CRISTA-SPAS-02); the Japanese Manipulator Flight Development (MFD); the Technology Applications and Science-01 (TAS-1) and the International Extreme Ultraviolet Hitchhiker-02 (IEH-02).

This was second flight of CRISTA-SPAS payload. CRISTASPAS- 02 also represented the fourth mission in a cooperative venture between the German Space Agency (DARA) and NASA. Payload included three telescopes and four spectrometers, deployed on flight day one, to gather data about Earth's middle atmosphere. After more than 200 hours of free flight, CRISTASPAS was retrieved on Aug. 16. Complementary instrument, the Middle Atmosphere High Resolution Spectrograph Investigation (MAHRSI) also performed well.

Data from STS-85 and first CRISTA-SPAS flight, STS-66 in 1994, expected to yield new insight into distribution of ozone in Earth's atmosphere. Once science operations were complete, CRISTA-SPAS used in simulation exercise to prepare for first International Space Station (ISS) assembly flight, STS-88, with the payload being manipulated as if it were the Functional Cargo Block (FGB) that will be attached to ISS Node 1.

TAS-1 was a Hitchhiker payload carrying eight experiments designed to demonstrate faster, better, cheaper avionics and processes: Solar Constant Experiment (SOLCON), Infrared Spectral Imaging Radiometer (ISIR) and Shuttle Laster Altimeter (SLA), all part of NASA's Mission to Planet Earth program; and the Critical Viscosity of Xenon (CVX), Space Experiment Module (SEM); Two Phase Flow (TPF); Cryogenic Flight Experiment (CFE) and Stand Alone Acceleration Measurement Device and the Wide-Band Stand Alone Acceleration Measurement Device (SAAMD/ WBSAAMD). All the experiments were completed successfully.

MFD designed to evaluate use of the Small Fine Arm that will be part of the future Japanese Experiment Module's Remote Manipulator System on ISS. Despite some glitches, MFD completed a series of exercises by crew on orbit as well as operators on ground. Two unrelated Japanese experiments, Two-Phase Fluid Loop Experiment (TPFLEX) and Evaluation of Space Environment and Effects on Materials (ESEM), were mounted near the Small Fine Arm in the payload bay.

IEH-02 was flying a second time and consisted of four experiments, all of which performed well on-orbit: Solar Extreme Ultraviolet Hitchhiker-2 (SHE); Ultraviolet Spectrography Telescope for Astronomical Research (UVSTAR); Distribution and Automation Technology Advancement Colorado Hitchhiker and Student Experiment of Solar Radiation (DATA-CHASER); and Shuttle Glow Experiment-5 and -6, all with common objective to investigate solar extreme ultraviolet (EUV) flux and EUV emissions of the Jupiter Io Plasma Torus system.

In-cabin payloads: Bioreactor Demonstration System-3 (BDS- 3), a cell biology research payload which has flown previously. On this flight, BDS used for growing colon cancer cells to a larger size than can be achieved on Earth. Protein Crystal Growth - Single Locker Thermal Enclosure System (PCG-STES); Midcourse Space Experiment (MSX); Shuttle Ionospheric Modification with Pulsed Local Exhaust (SIMPLEX); Southwest Ultraviolet Imaging System (SWUIS), used to observe the Hale-Bopp comet; two Get Away Special (GAS) payloads; Biological Research in Canisters- 10 (BRIC-10), one in a series of flights; and the Solid Surface Combustion Experiment (SSCE).

Crew also worked with the Orbiter Space Vision System (OSVS), which will be used during ISS assembly. OSVS features series of dots strategically placed on various payload and vehicle structures that permit precise alignment and pointing capability. Orbiter performance was nominal throughout the mission.

AKA: Discovery.
First Launch: 1997.08.07.
Last Launch: 1997.08.19.

Associated Programs
  • STS The Space Transportation System (Space Shuttle) was conceived originally as a completely reusable system that would provide cheap, routine access to space and replace all American and civilian military launch vehicles. Crippled by technological overreach, political compromise, and budget limitations, it instead ended up costing more than the expendable rockets it was to have replaced. STS sucked the money out of all other NASA projects for half a century. The military abandoned its use after the Challenger shuttle explosion in the 1980's. More...

Associated Launch Sites
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...
