Garneau was in the 1992 class of Astronaut Candidates (ASCAN). Wearing full parachute gear following a simulated parachute drop, Garneau has deployed a small life raft in a 25-feet deep pool in JSC's Weightless Environment Training Facility (WET-F). This portion of an astronaut's training is to prepare him or her for proper measures to take in the event of bailout over water. Garneau is assisted here by one of several SCUBA-equipped divers in the pool.

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.

Dr. Jernigan was about to be submerged in the Johnson Space Center's 25-ft. deep weightless environment training facility (WET-F) pool to simulate a contingency extravehicular activity (EVA). There is no EVA scheduled for STS-40, the Spacelab Life Sciences (SLS-1) mission.

S94-25956 (April 1994) --- Astronaut Catherine G. Coleman, mission specialist, wearing a high-fidelity training version of an Extravehicular Mobility Unit (EMU), trains for a contingency space walk at the Johnson Space Center?s (JSC) Weightless Environment Training Facility (WET-F). Coleman has recently been named as one of seven crew members for the U.S. Microgravity Laboratory (USML-2) mission. The 25-feet deep pool is used to train astronauts for mission specific space walk chores as well as for contingency Extravehicular Activity (EVA) tasks.
