S93-31702 (3 April 1993) --- Astronaut David A. Wolf participates in training for contingency extravehicular activity (EVA) for the STS-58 mission. Behind Wolf, sharing the platform with him is astronaut Shannon W. Lucid. For simulation purposes, the two mission specialists were about to be submerged to a point of neutral buoyancy in the Johnson Space Center's (JSC) Weightless Environment Training Facility (WET-F). Though the Spacelab Life Sciences (SLS-2) mission does not include a planned EVA, all crews designate members to learn proper procedures to perform outside the spacecraft in the event of failure of remote means to accomplish those tasks.
