Mission overview

The mission STS -42 began with a running start on 22 January 1992. 's Payload bay of the Space Shuttle there was the microgravity laboratory -1 (IML -1). This based on the Spacelab module contained experiments to explore the complex effects of weightlessness on living organisms and other materials. In order to conduct experiments around the clock, the crew worked in shifts. Grave, Oswald, Thagard and Bondar made ​​the blue team, while Hilmer, Readdy and Merbold were the red team.

In addition to the experiments in the IML - 1, 10 Get-Away canisters were in the payload bay, where expired automated experiments. On the middle deck of the shuttle itself were also experiments on biological topics. To increase the scientific yield of the flight, the mission was finally extended by one day, so the landing took place at Edwards Air Force Base only on January 30. Two weeks later, the Discovery was flown back to KSC.
