Unless you’ve been living under a rock you will know that Buzz Aldrin was one of the first two men to land on the moon, piloting the lunar module to the surface in 1969.
He earned a bachelor of science degree in mechanical engineering at West Point in 1951 before joining the air force as a fighter pilot where he served in the Korean war. In 1963 after completing a Doctor of science degree in astronautics from MIT, he was selected for the NASA astronaut program. He left NASA in 1971, and retired from the air force in 1972.
He has written a number of books, including two autobiographies. Return to Earth in 1973, and Magnificent Desolation in 2009. In these books he revealed his struggle with depression and alcohol, and how seeking professional help improved his quality of life.
In 1985 he devised a trajectory around Earth and Mars now known as the Aldrin Cycler, which would allow space craft to travel too and from Mars easily.
He has remained a strong and active advocate of space exploration, and a fierce critic of those who theorize that the moon landings were faked.
