STS083-317-009 (4-8 April 1997) --- Astronaut Susan L. Still, pilot, goes over a checklist at the control panel on the aft flight deck of the Earth-orbiting Space Shuttle Columbia. Scheduled originally as a 16-day mission, the Microgravity Sciences Laboratory (MSL-1) flight completed about one-fourth of its manifest time frame prior to being cut short by a power shortage.
