GEMINI-TITAN (GT)-12 - ASTRONAUT TRAINING - UNDERWATER - FOOT PLATES - MD

S66-54939 (29 Oct. 1966) --- Astronaut Edwin E. Aldrin Jr., pilot for the Gemini-12 spaceflight, practices work tasks during underwater zero-gravity training. He is placing his feet into a special foot plate in an adapter section of the spacecraft. The foot plate will help secure him to the spacecraft during extravehicular activity (EVA). The underwater environment closely simulates the zero-gravity condition found in space. Photo credit: NASA
