Buzz Aldrin

Forty-two years after the first moon landing, and with a new lunar X Prize looming, we take a look back at a few of the key Apollo missions, and specifically at the Lunar Modules that brought the astronauts to and from the surface of the moon.

This now-legendary photo, taken by Neil Armstrong, shows Edwin "Buzz" Aldrin descending a ladder from the Eagle lunar lander on to the moon's surface. Aldrin acted as pilot of the Lunar Module on the Apollo 11 mission.
