life:

After 34-year-old astronaut Ed White became the first American to walk in space on June 3,1965, both White and his Gemini IV crew mate, Command Pilot James McDivitt, shared the story of the mission with LIFE magazine. LIFE then ran, as the cover above proudly declares, “16 Pages of Fantastic Color” from White’s “marvelous romp” in space.
