Framed by the Vehicle Assembly Building at right and the Mate-Demate Device at left, the Space Shuttle orbiter Columbia (STS-94) glided onto Runway 33 of Kennedy Space Center's Shuttle Landing Facility. On board for the reflight of STS-83 were a crew of seven and the Microgravity Science Laboratory-1 (MSL-1)which was managed by scientists and engineers from the Marshall Space Flight Center. Mission STS-94 marked the 23rd flight of Columbia and the 85th mission flown since the start of the Space Shuttle program in 1981. During the mission, the Spacelab module was used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station while the flight crew conducted combustion, protein crystal growth and materials processing experiments.

Still underneath the Space Shuttle orbiter Columbia after an end-of-mission landing on Runway 33 of KSC’s Shuttle Landing Facility July 17 to complete the Microgravity Science Laboratory-1 (MSL-1) mission. Six of the seven STS-94 crew members took the traditional post-landing walk around the orbiter, meeting with members of the orbiter recovery convoy team and inspecting the vehicle that carried them through space for nearly 17 days on a highly successful microgravity research mission

STS-94 Commander James D. Halsell, Jr., arrives at the Shuttle Landing Facility aboard a T-38 jet in preparation for the reflight of the Microgravity Science Laboratory-1 mission. Launch is scheduled for July 1, 1997, at 2:37 p.m. EDT. The laboratory was scheduled to fly again with the full complement of STS-83 experiments after that mission was cut short due to a faulty fuel cell. During the scheduled 16-day STS-94 mission, the experiments will be used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station while the flight crew conducts combustion, protein crystal growth and materials processing experiments

KENNEDY SPACE CENTER, FLA. - Roger Crouch, a payload specialist, talks to the media prior to the launch at 3:51 p.m. of Space Shuttle Discovery on the historic Return to Flight mission STS-114. He has flown on two Shuttle missions, STS-83 and STS-94. STS-114 is the 114th Space Shuttle flight and the 31st for Discovery. The 12-day mission is expected to end with touchdown at the Shuttle Landing Facility at 11:06 a.m. July 25.

Gernhardt , Payload Commander Janice Voss, and Payload Specialists Roger K. Crouch and Gregory T. Linteris. Mission elapsed time for STS-94 was 15 days,16 hours, 44 seconds. During the Microgravity Science Laboratory-1 (MSL-1) mission, the Spacelab module was used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station while the flight crew conducted combustion, protein crystal growth and materials processing experiments. This mission was a reflight of the STS-83 mission that lifted off from KSC in April of this year. That space flight was cut short due to indications of a faulty fuel cell.
