On June 3rd, 1965, Edward White became the first American astronaut to walk in space. His mission commander, Jame McDivitt snapped this picture over the Pacific Ocean over the course of the Gemini 4 mission. He later described the order to return to the spacecraft as being “the saddest moment of his life.”
White was selected for the Apollo 1 mission in March 1966, along with astronauts Gus Grissom and Robert Chaffee. In 1967, the crew perished when a ‘plugs-out test’ resulted in a fire, trapping the astronauts.
