After graduating from the U.S. Military Academy, he completed U.S. Air Force pilot training in 1952 and flew over 60 combat missions during the Korean War. In 1963 NASA selected him as an astronaut. He served as backup pilot of the Gemini IX and as pilot for Gemini XII in 1966. He was made backup command module pilot for Apollo VIII and lunar module pilot for Apollo XI, the most famous flight in space history, which landed on the moon July 20, 1969. Aldrin was the second man to walk on the moon; Neil Armstrong, the first man, beat Aldrin by just 15 minutes.
