(June 3, 1965) - Astronaut Edward H. White, pilot of the Gemini-Titan IV space flight, floats in the zero gravity of the space outside the Gemini IV spacecraft. His face is covered with a shaded visor to protect him from the unfiltered rays of the sun. White became the first American astronaut to walk in space. He remained outside the space shuttle for 21 minutes during the third revolution of the Gemini IV mission. He wears a suit specially designed for EVA. His right hand holds the HHSMU, with which he controlled his movements while he was in space, and a camera is attached to the HHSMU. He was attached to the Space Shuttle by a 25-foot umbilical line and a 23-foot tie line, both wrapped together with golden tape to form a cordon. He is carrying a package of control of emergency oxygen supply. Astronaut James A. McDivitt is a command pilot for the GT-4 mission. The mission consisted of a four-day flight at 62 laps, during which McDivitt and White conducted a series of scientific and technical experiments.
