PAD - 6/3/92

Payload:
USML-01,IPMP,SAREX-II,UVPI
Mission Objectives:

Launch:
June 25, 1992, 12:12:23 p.m. EDT. Launch delayed 5 minutes due to weather concerns. Launch Weight: 257,265 lbs.
Orbit:
Altitude: 160nm
Inclination: 28.45 degrees
Orbits: 221
Duration: 13 days, 19 hours, 3O minutes, O4 seconds.
Distance: 5,758,000 miles

Hardware:
SRB: BI-051
SRM: 360L/M024
ET : 45/LWT-38
MLP : 3
SSME-1: SN-2019
SSME-2: SN-2031
SSME-3: SN-2011

Landing:
July 9, 1992, 7:43 a.m. EDT, Runway 33, Kennedy Space Center, Fla., Rollout distance: 1O,2OO feet. Rollout time: 59 seconds. Drag chute used. Landing diverted to KSC because of bad weather at the primary landing site at Edwards Air Force Base, Calif. Marked 1Oth Space Shuttle landing at KSC and first for the orbiter COLUMBIA. Mission duration eclipsed all previous U.S. manned space flights except the three flights to the Skylab Space Station in 1973 and 1974. Landing Weight: 228,127 lbs.

Mission Highlights:
Primary payload was the United States Microgravity Laboratory-I (USML-1), a manned Spacelab module with connecting tunnel to the orbiter crew compartment. USML-l was a national effort to advance microgravity research in a broad number of disciplines. The 13-day mission, the first Extended Duration Orbiter flight and the longest Space Shuttle mission to date, also provided new information on the effects of long-term human stay in space. Experiments conducted were: Crystal Growth Furnace (CGF), Drop Physics Module (DPM), Surface Tension Driven Convection Experiment (STDCE), Zeolite Crystal Growth (ZCG), Protein Crystal Growth (PCG), Glovebox Facility (GBX), Space Acceleration Measurement System (SAMS), Generic Bioprocessing Apparatus (GBA), Astroculture-1 (ASC), Extended Duration Orbiter Medical Project (EDOMP), and Solid Surface Combustion Experiment (SSCE).
Secondary experiments included Investigation in Polymer Membrane Processing (IPMP), Shuttle amateur Radio Experiment II (SAREX-II), and Ultraviolet Plume Instrument (UVPI).

AKA: Columbia.
First Launch: 1992.06.25.
Last Launch: 1992.07.09.
Duration: 13.81 days.

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...
