STS083-346-002 (4-8 April 1997) --- Astronaut Susan L. Still, pilot, appears excited about the chore of vacuuming in the Spacelab Science Module as astronaut Michael L. Gernhardt approaches with the vacuum cleaner. Gernhardt is one of three mission specialists who joined the flight operations crew and two payload specialists in support of the Microgravity Science Laboratory (MSL-1) mission. The crew members were less than a fourth of the way through a scheduled 16-day flight when a power problem cut short their planned stay.
