STS-54 MS3 Helms tests CCA equipment prior to an underwater simulation at JSC

S92-42755 (31 July 1992) --- Astronaut Susan J. Helms, mission specialist assigned to fly aboard the Space Shuttle Endeavour for the STS-54 mission, completes the donning of her spacesuit before a training exercise. Though not assigned to the scheduled extravehicular activity (EVA), Helms is trained in the weightless environment training facility (WET-F). She will aid astronauts Gregory J. Harbaugh and Mario Runco Jr. in their planned EVA, scheduled for January of next year, and serve a backup role. Wearing this high fidelity training version of the extravehicular mobility unit (EMU), Helms was later lowered into the 25-ft. deep WET-F pool. The pressurized suit is weighted so as to allow Helms to achieve neutral buoyancy and simulate the various chores of the spacewalk.
