KENNEDY SPACE CENTER, FLA. - Greeted by cheers from wellwishers at KSC and eager for their ventur into space on the Microgrvity Science Laboratory-1 (MSL-1) mission, the STS-83 astronauts depart the Operations and Checkout Building on their way to Launch Pad 39A. Leading the seven-member crew is Mission Commander James D. Halsell Jr. Behind Halsell and to his right is Pilot Susan L. Still. Behind Still is Payload Commander Janice Voss, with Mission Specialist Donald A. Thomas to her left. Behind Thomas, in order, are Mission Specialist Michael L. Gernhardt and Payload Specialists Roger K. Crouch and Gregory T. Linteris. During the scheduled 16-day STS-83 mission, the MSL-1 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. Also onboard is the Hitchhiker Cryogenic Flexible Diode (CRYOFD) experiment payload, which is attched to the right side of Columbia's payload bay.

STS083-302-005 (4-8 April 1997) --- Payload specialist Gregory T. Linteris enters data on the progress of a Microgravity Sciences Laboratory (MSL-1) experiment on a lap top computer aboard the Spacelab Science Module while astronaut Donald A. Thomas, mission specialist, checks an experiment in the background. Linteris and Thomas, along with four other NASA astronauts and a second payload specialist supporting the Microgravity Sciences Laboratory (MSL-1) mission were less than a fourth of the way through a scheduled 16-day flight when a power problem cut short their planned stay.

The Spacelab long transfer tunnel that leads from the Space Shuttle Orbiter Columbia’s crew airlock to the Microgravity Science Laboratory-1 (MSL-1) Spacelab module in the spaceplane’s payload bay is removed in Orbiter Processing Facility 1. The tunnel was taken out to allow better access to the MSL-1 module during reservicing operations to prepare it for its reflight as MSL-1R. That mission is now scheduled to lift off July 1. This was the first time that this type of payload was reserviced without removing it from the payload bay. This new procedure pioneers processing efforts for quick relaunch turnaround times for future payloads. The Spacelab module 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 reflight, 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

Halsell, along with four other NASA astronauts and two payload specialists supporting the Microgravity Sciences Laboratory (MSL-1) mission were less than a fourth of the way through a scheduled 16-day flight when a power problem cut short their planned stay.

Three members of the STS-83 flight crew head toward the orbiter access arm on the 195-foot level Launch of Pad 39A that will take them to the crew hatch of the Space Shuttle Columbia during Terminal Countdown Demonstration Test (TCDT) exercises for that mission. Mission Specialist Donald A. Thomas is in the center of the group. Other crew members on the 16-day Microgravity Science Laboratory-1 (MSL-1) mission are: Mission Commander James D. Halsell, Jr.; Pilot Susan L. Still; Payload Commander Janice Voss; Mission Specialist Michael L.Gernhardt; and Payload Specialists Gregory T. Linteris and Roger K. Crouch

The soon-to-be-spaceborne Space Shuttle Columbia gets a flyby visit from the Comet Hale-Bopp (shown as the streak at left center) while awaiting launch on the STS-83 mission. This photo was taken the night before the planned liftoff on April 4, 1997. The Rotating Service Structure at Launch Pad 39A has been moved back prior to the start of operations to fuel the external tank. The primary objective of the STS-83 flight is to operate the Microgravity Science Laboratory-1 (MSL-1), which will test some of the hardware, facilities and procedures that will be used on the International Space Station. Columbia will have a crew of seven

The potential for investigating combustion at the limits of flammability, and the implications for spacecraft fire safety, led to the Structures Of Flame Balls At Low Lewis-number (SOFBALL) experiment flown twice aboard the Space Shuttle in 1997. The success there led to reflight on STS-107 Research 1 mission plarned for 2002. This image is a video frame which shows MSL-1 flameballs which are intrinsically dim, thus requiring the use of image intensifiers on video cameras. The principal investigator is Dr. Paul Ronney of the University of Southern California, Los Angeles. Glenn Research in Cleveland, OH, manages the project.

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

Typical metal sample that was processed by TEMPUS (Tiegelfreies Elektromagnetisches Prozessieren Unter Schwerelosigkeit), an electromagnetic levitation facility developed by German researchers and flown on the IML-2 and MSL-1 and 1R Spacelab missions. Electromagnetic levitation is used commonly in ground-based experiments to melt and then cool metallic melts below their freezing points without solidification occurring. Sample size is limited in ground-based experiments. Research with TEMPUS aboard Spacelab allowed scientists to study the viscosity, surface tension, and other properties of several metals and alloys while undercooled (i.e., cooled below their normal solidification points). The sample is about 1 cm (2/5 inch) in diameter.
