S92-35764 (12 May 1992) --- Wearing extravehicular mobility units (EMU's) and fitted with weights for neutral buoyancy are three trouble-shooting astronauts. The astronauts practiced techniques for capturing Intelsat, and climbing into the airlock mockup in the Weightless Environment Training Facility (WETF). No apparent problems were identified in placing three astronauts in the airlock at one time. Left to right are, Michael R. (Rich) Clifford, Story Musgrave, and James S. Voss. Three Endeavour astronauts, Pierre J. Thuot, Richard J. Hieb and Thomas D. Akers, will attempt to capture Intelsat again on May 13. Clifford played the role of Hieb, Musgrave for Thuot, and Voss, Akers.
