1965-043A
Gemini IV saw the first American spacewalk, by pilot Ed White.
Immediately after orbit insertion, the astronauts attempted to rendezvous with the Titan second stage, but this experiment was abandoned after a few minutes when too much OAMS fuel was consumed.
The cabin was depressurized at 1933, with the hatch open at 1934. White stood up in the hatch at 1936, and left the spacecraft at 1946, attached by an umbilical. He used a gas gun to move around in space, and returned to the cabin at 2006. The hatch was closed at 2010 and the cabin repressurized at 2013 after 39 m 15s. Command Pilot James McDivitt had remained within the unpressurized cabin, which was open to space during the EVA.
White used the G4C spacesuit and a ZIP (Zero g Integral Propulsion) Unit for maneuvering and the VCM device for life support. A planned equipment dump was cancelled, but during the EVA an outer glove and a gold-covered visor were discarded.
Splashdown was at 27 44 N, 74 11 W in the Atlantic; the spacecraft was recovered by the USS Wasp.
