Buzz Aldrin (b. 1930) is an American astronaut, and the second person to walk on the Moon. Born in Montclair, New Jersey, he turned down a full scholarship to the Massachusetts Institute of Technology (MIT) in favor of an education at West Point Academy, where he graduated with a degree in mechanical engineering. After receiving a commission by the United States Air Force (USAF), Aldrin flew sixty-six combat missions during the Korean War, after which he continued his education at MIT before becoming an astronaut in 1963. Unlike most of the others chosen for that role, Aldrin was never a test pilot, but attracted the attention of the National Aeronautics and Space Administration (NASA) with his success in the USAF and his graduate work at MIT. Aldrin flew on Gemini 12, and was selected--along with Neil Armstrong and Michael Collins--for Apollo 11, the first mission to the surface of the Moon. Since retiring from NASA, he has done charity work and written numerous books, including Encounter with Tiber (1996), his first science fiction novel.
