Edwin Eugene Aldrin Jr. (Buzz Aldrin), born on January 20, 1930, is an American former astronaut, engineer, and fighter pilot. Aldrin made three spacewalks as pilot of the 1966 Gemini 12 mission, and, as Lunar Module Eagle pilot on the 1969 Apollo 11 mission, he and mission commander Neil Armstrong were the first two people to land on the Moon. Aldrin is the last surviving crew member of Apollo 11. His first space flight was in 1966 on Gemini 12, during which he spent over five hours on extravehicular activity. Three years later, Aldrin set foot on the Moon at 03:15:16 on July 21, 1969 (UTC), nineteen minutes after Armstrong first touched the surface, while command module pilot Michael Collins remained in lunar orbit. A Presbyterian elder, Aldrin became the first person to hold a religious ceremony on the Moon when he privately took communion.
