STS-42 was a NASA Space Shuttle Discovery mission with the Spacelab module. Liftoff was originally scheduled for 8:45 EST (13:45 UTC) on January 22, 1992, but the launch was delayed due to weather constraints. Discovery successfully lifted off an hour later at 9:52:33 EST (14:52:33 UTC) on her 14th flight. The main goal of the mission was to study the effects of microgravity on a variety of organisms. The shuttle landed at 8:07:17 PST (16:07:17 UTC) on January 30, 1992, on Runway 22, Edwards Air Force Base, California. STS-42 was the first of two flights in 1992 of Discovery, the second of which occurred during STS-53, which launched on December 2, 1992. The mission was also the last mission of the Space Shuttle Discovery to have a seven-member crew until STS-82, which was launched on February 11, 1997.
