Astronaut Anna Fisher practices control of the RMS in a trainer

S84-40162 (21 Aug. 1984) --- Astronaut Anna L. Fisher controls the Remote Manipulator System (RMS) arm from inside the "orbiter" as part of her training program in the Johnson Space Center's Shuttle Mock-up and Integration Laboratory. Dr. Fisher, one of three mission specialists for mission 51-A, is inside the cabin portion of a trainer called the Manipulatory Development Facility (MDF). She is able to operate the arm in conjunction with an air bearing floor and to log a great deal of rehearsal time for her flight, on which the retrieval of a low-orbiting communications satellite is planned.
