Mission Specialist Bruce McCandless free flying in an MMU (Manned Maneuvering Unit)
In response to some of the rather apocryphal science portrayed in the recent movie Gravity, NASA has posted a roster of photos of the real thing. This image of Mission Specialist Bruce McCandless free flying in an MMU (Manned Maneuvering Unit) in 1984 shows him further away from the safety of his mothership than any previous astronaut, and seems in one image to capture the incredible technological advances and aspirations of the Twentieth Century.
