S90-44106 (August 1990) --- Astronaut Guion S. Bluford, mission specialist for STS-39, wearing part of an extravehicular mobility unit (EMU) spacesuit, prepares to participate in a training session for the scheduled
March 1991 spaceflight. Soon after this picture was taken, Bluford was lowered into water by a hoist device for the underwater rehearsal of a contingency EVA. The scene is in the Johnson Space Center's weightless environment training facility (WET-F) which houses a 25-ft. deep pool (visible in right background).
