Gemini EVA Maneuvering Unit

This maneuvering unit mockup was designed during the Gemini program of the early 1960s in an effect to study the best ways to work outside of spacecraft. Similar units became operational in the early 1980s during the Space Shuttle program and were used to retrieve several satellites.
