About Buzz Aldrin
Buzz Aldrin ( AWL-drin; born Edwin Eugene Aldrin Jr.; January 20, 1930) is an American former astronaut, aeronautical engineer, and fighter pilot. He was the second person to walk on the Moon after mission commander Neil Armstrong. He made three spacewalks as pilot of NASA’s 1966 Gemini 12 mission, and was the Lunar Module Eagle pilot on the 1969 Apollo 11 mission. Following the deaths of Armstrong in 2012 and pilot Michael Collins in 2021, Aldrin is the last surviving Apollo 11 crew member, and the oldest living astronaut. Born in Glen Ridge, New Jersey, Aldrin graduated third in the class of 1951 from the United States Military Academy at West Point with a degree in mechanical engineering. He was commissioned into the United States Air Force and served as a jet fighter pilot during the Korean War. He flew 66 combat missions and shot down two MiG-15 fighter jets. After earning a Doctor of Science degree in astronautics from the Massachusetts Institute of Technology (MIT), Aldrin was selected as a member of NASA's Astronaut Group 3, making him the first astronaut with a doctoral degree. His doctoral thesis, Line-of-Sight Guidance Techniques for Manned Orbital Rendezvous, earned him the nickname "Dr. Rendezvous" from fellow astronauts. 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, which was the first food and liquid to be consumed there. After leaving NASA in 1971, Aldrin became Commandant of the U.S. Air Force Test Pilot School. He retired from the Air Force in 1972 after 21 years of service. His autobiographies Return to Earth (1973) and Magnificent Desolation (2009) recount his struggles with clinical depression and alcoholism in the years after leaving NASA. Aldrin continues to advocate for space exploration, particularly a human mission to Mars. He developed the Aldrin cycler, a special spacecraft trajectory that makes travel to Mars more efficient in terms of time and propellant. He has been accorded numerous honors, including the Presidential Medal of Freedom in 1969. Following Jim Lovell's death in 2025, Aldrin became the oldest living astronaut.
