Standing on a mobile platform, astronaut Catherine G. Coleman is assisted with final touches for suiting up for a training exercise in the deep pool of JSC's Neutral Buoyancy Laboratory (NBL). Coleman was participating in a simulation of a contingency space walk in preparation for the STS-93 mission next year. The mission specialist will join four other NASA astronauts for the Space Shuttle Columbia flight, scheduled for spring. The training version of the extravehicular mobility unit (EMU) that Coleman is wearing is weighted and otherwise accommodated to afford neutral buoyancy in the deep pool.
