On this day in history, June 3, 1965, astronaut aboard the Gemini Four, Edward White, became the first American to walk in space.
Gemini Four was launched from Cape Kennedy on June 3, 1965 and returned four days later. The astronauts on board were Major James McDivitt and Major Edward White.
White set a world record for the longest time spent outside an orbiting space capsule. Connected to the craft by a 25 foot "lifeline", White "walked" or rather, floated around in space for twenty minutes. The flight also set records for endurance, number of orbits and altitude.
Soviet cosmonaut Alexei Leonov was the first man to step outside of an orbiting space ship.
