Underwater EVA training in the WETF with astronauts Nelson and van Hoften

S83-42895 (19 Oct 1983) --- Astronauts George D. Nelson and James D. van Hoften, NASA Flight STS-41C mission specialists, offer an underwater version of a preview of their mission's extravehicular activity (EVA). The April 1984 flight includes as one of its primary objectives a two-person EVA and a visit to the damaged Solar Maximum Satellite (SMS). Van Hoften, left, and Nelson work here with the mobile foot restraint (MFR), which attaches to the remote manipulator system (RMS) arm to form a "cherry-picker" device. Van Hoften is standing on the MFR. The two are making use of the Johnson Space Center's (JSC) weightless environment training facility (WET-F). This photograph was taken by Otis Imboden.
