NASA Astronaut Ed White made history on June 3, 1965, when he floated out of the hatch of his Gemini 4 capsule into the void of space. The first American “spacewalk” – or Extravehicular Activity (EVA) – lasted 23 minutes, not nearly long enough for White. He later said the spacewalk was the most comfortable part of the mission, and said the order to end it was the “saddest moment” of his life. White was attached to the capsule by a 25-foot umbilical cord. He initially used a gas-powered gun held in his hand to maneuver. After the first three minutes, the fuel ran out and White moved around by twisting his body and pulling on the cord. This photograph of White’s spacewalk was taken by Gemini 4 Commander James McDivitt, still inside the spacecraft.
