Mission Objectives:

Launch:
November 26, 1985, 7:29:00 p.m. EST. Launch proceeded as scheduled with no delays. Launch Weight: 261,455 lbs.
Orbit:
Altitude: 225nm
Inclination: 28.5 degrees
Orbits: 109
Duration: Six days, 21 hours, four minutes, 49 seconds.
Distance: 2,838,972 miles

Hardware:
SRB: BI-023
SRM: L023(HPM)
ET : 22/LWT-15
MLP : 2
SSME-1: SN-2011
SSME-2: SN-2019
SSME-3: SN-2017

Landing:
December 3, 1985, 1:33:49 p.m. PST, Runway 22, Edwards Air Force Base, Calif. Rollout distance: 10,759 feet. Rollout time: 78 seconds. Mission shortened one revolution due to lightning conditions at Edwards. Landed on concrete runway because lake bed was wet. Orbiter returned to KSC Dec. 7, 1985. Landing Weight: 205,732 lbs.

Mission Highlights:
Three communications satellites deployed: MORE LOS-B (Mexico), AUSSAT-2 (Australia) and SATCOM KU-2 (RCA Americom). MORELOS-B and AUSSAT-2 attached to Payload Assist Module-D motors, SATCOM KU-2 to a PAM-D2 designed for heavier payloads. Two experiments conducted to test assembling erectable structures in space: Experimental Assembly of Structures in Extravehicular Activity (EASE) and Assembly Concept for Construction of Erectable Space Structure (ACCESS). Experiments required two space walks by Spring and Ross lasting five hours, 32 minutes, and six hours, 38 minutes, respectively. Middeck payloads: Continuous Flow Electrophoresis System (CFES); Diffusive Mixing of Organic Solutions (DMOS); Morelos Payload Specialist Experiments (MPSE) and Orbiter Experiments (OEX). In payload bay: Get Away Special and IMAX Cargo Bay Camera (ICBC).

AKA: Atlantis.
Location: First Mexican astronaut..
First Launch: 1985.11.27.
Last Launch: 1985.12.03.
Duration: 6.88 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...
