S89-41600 (Nov 1989) --- Astronaut Bonnie J. Dunbar, wearing an extravehicular mobility unit (EMU) spacesuit, prepares to don a helmet and be lowered by a hoist device for a session of underwater training in the Johnson Space Center's weightless environment training facility (WET-F). Minutes later, Astronauts Dunbar and G. David Low, mission specialists, were neutrally buoyant in the nearby 25-ft. deep pool simulating a contingency extravehicular activity (EVA) for the scheduled December 1989 STS-32 mission. There are no scheduled EVAs for the crew, whose main missions are to retrieve the Long Duration Exposure Facility (LDEF) and to deploy a Syncom satellite.
