Crew Training - STS-41D - JSC

S84-28204 (26 Feb 1984) --- Astronaut Richard M. (Mike) Mullane, one of three 41-D mission specialists, is almost ready for submerging in the 25 ft. deep facility used to simulate space tasks on earth. Moments later, the 41-D crewmember was floating around a submerged Shuttle mockup simulating a contignency EVA for his seven-day flight. Partially pictured in the background is Astronaut Steven A. Hawley, who would share EVA duties with Mullane in the event an EVA was deemed necessary. All Shuttle crews, many of which are not scheduled for definite EVAs, possess team members trained to perform in space certain tasks normally done remotely in the event of systems failures. Among those contingent tasks is the manual closing of the
Shuttle's cargo bay doors. This photograph was taken by Otis Imboden.
