Apollo 11, July 20, 1969.

Astronaut Neil A. Armstrong, Apollo ll mission commander, at the modular equipment storage assembly (MESA) of the Lunar Module "Eagle" on the historic first extravehicular activity (EVA) on the lunar surface. Astronaut Edwin E. Aldrin Jr. took the photograph with a Hasselblad 70mm camera. Most photos from the Apollo 11 mission show Buzz Aldrin. This is one of only a few that show Neil Armstrong (some of these are blurry).
