STS-40
Bagian served on the crew of STS-40 Spacelab Life Sciences (SLS-1), the first dedicated space and life sciences mission, which launched from the Kennedy Space Center, Florida, on June 5, 1991. SLS-1 was a nine-day mission during which crew members performed experiments which explored how the heart, blood vessels, lungs, kidneys, and hormone-secreting glands respond to microgravity, the causes of space sickness, and changes in muscles, bones, and cells which occur in humans during space flight. Other payloads included experiments designed to investigate materials science, plant biology and cosmic radiation. In addition to the scheduled payload activities on STS-40, Bagian was successful in personally devising and implementing repair procedures for malfunctioning experiment hardware which allowed all scheduled scientific objectives to be successfully accomplished. Following 146 orbits of the Earth, Columbia and her crew landed at Edwards Air Force Base, California, on June 14, 1991. Completion of this flight logged him an additional 218 hours in space.
