STS-83 Microgravity Science Laboratory-1 (MSL-1) 04/04/1997 04/08/1997 83rd Space Shuttle Mission 22nd Flight of Columbia Crew: James D. Halsell, Jr., Commander Susan L. Still, Pilot Janice Voss, Payload Commander Michael L. Gernhardt, Mission Specialist Donald A. Thomas, Mission Specialist Roger K. Crouch, Payload Specialist Gregory T. Linteris, Payload Specialist The primary payload, the pressurized Microgravity Science Laboratory-1 (MSL-1) housed in Columbia's cargo bay, was being flown for the first time and contained a plethora of life science and materials experiments. Fuel cell failure caused the mission to be cut short. Opportunity for an additional Shuttle flight in 1997 was made possible by the postponement of an International Space Station construction flight initially scheduled for late 1997. The STS-83 re-flight was originally designated STS-83R, but was redesignated STS-94.
