S87-26630 (March 1987) --- Astronaut Charles D. (Sam) Gemar, wearing a training version of the Extravehicular Mobility Unit (EMU) space suit, prepares to be emersed in the 25-ft. deep waters of the Weightless Environment Training Facility (WET-F) at the Johnson Space Center (JSC). Once underwater, Gemar was able to achieve a neutrally buoyant state and to simulate the floating type activities of an astronaut in microgravity.
