This very brave astronaut is Bruce McCandless II, the first man to take an untethered space walk, on a Challenger mission in 1984. He used a back-pack propulsion system called a Manned Maneuvering Unit to control his movement. You may recognize this semi-iconic photograph, taken of Bruce during this very spacewalk. Image via.
