With the Space Shuttle Orbiter Columbia in the background, STS-83 Mission Commander James D. Halsell (center) gives a post-landing briefing on Runway 33 at KSC’s Shuttle Landing Facility. Columbia landed at 2:33:11 p. m. EDT, April 8, to conclude the Microgravity Science Laboratory-1 (MSL-1) mission. The other flight crew members (from left) are: Payload Specialist Roger K. Crouch; Payload Commander Janice Voss; Mission Specialist Michael L. Gernhardt; Pilot Susan L. Still; Payload Specialist Gregory T. Linteris; and Mission Specialist Donald A. Thomas. At main gear touchdown, the STS-83 mission duration was 3 days, 23 hours, 12 minutes. The planned 16-day mission was cut short by a faulty fuel cell. This is only the third time in Shuttle program history that an orbiter was brought home early due to mechanical problems. This was also the 36th KSC landing since the program began in 1981
