S66-33162 (May 1966) --- Test subject Fred Spross, Crew Systems Division, wears configured extravehicular spacesuit assembly and Extravehicular Life Support System chest pack. The spacesuit legs are covered with Chromel R, which is a cloth woven from stainless steel fibers, used to protect the suit and astronaut from the hot exhaust thrust of the Astronaut Maneuvering Unit backpack. The Gemini spacesuit, backpack and chest pack comprise the AMU, a system which is essentially a miniature manned spacecraft. Astronaut Eugene A. Cernan will wear the AMU during his Gemini-9A extravehicular activity (EVA). Photo credit: NASA
