AMU worn by test subject

S66-33163 (May 1966) --- Rear view of the Astronaut Maneuvering Unit (AMU), worn by test subject Fred Spross, Crew Systems Division. The Gemini spacesuit, backpack and chest pack comprise the AMU, a system which is essentially a miniature manned spacecraft. The spacesuit legs are covered with Chromel R, which is a cloth woven from stainless steel fibers, used to protect the astronaut and suit from the hot exhaust thrust of the AMU backpack. Astronaut Eugene A. Cernan will wear the AMU during his Gemin-9A extravehicular activity (EVA). Photo credit: NASA
