Buzz Aldrin
Buzz Aldrin is an American former astronaut, aeronautical engineer, and fighter pilot. He made three spacewalks as pilot of the 1966 Gemini 12 mission, and was the Lunar Module Eagle pilot on the 1969 Apollo 11 mission. He was the second person to walk on the Moon after mission commander Neil Armstrong. Following the deaths of Armstrong in 2012 and pilot Michael Collins in 2021, he is the last surviving Apollo 11 crew member. Following Jim Lovell's death in 2025, Aldrin became 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, 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, 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 and Magnificent Desolation 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.
Early life and education
Aldrin was born Edwin Eugene Aldrin Jr. on January 20, 1930, at Mountainside Hospital in Glen Ridge, New Jersey. His parents, Edwin Eugene Aldrin Sr. and Marion Aldrin, lived in neighboring Montclair. His father was an Army aviator during World War I and the assistant commandant of the Army's test pilot school at McCook Field, Ohio, from 1919 to 1922, but left the Army in 1928 and became an executive at Standard Oil. Aldrin had two sisters: Madeleine, who was four years older, and Fay Ann, who was a year and a half older. His nickname, which became his legal first name in 1988, arose as a result of Fay's mispronouncing "brother" as "buzzer", which was then shortened to "Buzz". He was a Boy Scout, achieving the rank of Tenderfoot Scout.Aldrin did well in school, maintaining an A average. He played football and was the starting center for Montclair High School's undefeated 1946 state champion team. His father wanted him to go to the United States Naval Academy in Annapolis, Maryland, and enrolled him at nearby Severn School, a preparatory school for Annapolis, and even secured him a Naval Academy appointment from Albert W. Hawkes, one of the United States senators from New Jersey. Aldrin attended Severn School in 1946, but had other ideas about his future career. He suffered from seasickness and considered ships a distraction from flying airplanes. He faced down his father and told him to ask Hawkes to change the nomination to the United States Military Academy at West Point, New York.
Aldrin entered West Point in 1947. He did well academically, finishing first in his class his plebe year. Aldrin was also an excellent athlete, competing in pole vault for the academy track and field team. In 1950, he traveled with a group of West Point cadets to Japan and the Philippines to study the military government policies of Douglas MacArthur. During the trip, the Korean War broke out. On June 5, 1951, Aldrin graduated third in the class of 1951 with a Bachelor of Science degree in mechanical engineering.
Military career
Among the top of his class, Aldrin had his choice of assignments. He chose the United States Air Force, which had become a separate service in 1947 while Aldrin was still at West Point and did not yet have its own academy. He was commissioned as a second lieutenant and underwent basic flight training in T-6 Texans at Bartow Air Base in Florida. His classmates included Sam Johnson, who later became a prisoner of war in Vietnam; the two became friends. At one point, Aldrin attempted a double Immelmann turn in a T-28 Trojan and suffered a grayout. He recovered in time to pull out at about, averting what would have been a fatal crash.File:Buzz Aldrin in the cockpit of an F-86 Sabre.png|thumb|left|Aldrin in the cockpit of a 51st Fighter Interceptor Wing F-86 Sabre after shooting down a MiG-15 fighter during the Korean War|alt=Aldrin in a cockpit with canopy pulled back
When Aldrin was deciding what sort of aircraft he should fly, his father advised him to choose bombers, because command of a bomber crew gave an opportunity to learn and hone leadership skills, which could open up better prospects for career advancement. Aldrin chose instead to fly fighters. He moved to Nellis Air Force Base in Las Vegas, where he learned to fly the F-80 Shooting Star and the F-86 Sabre. Like most jet fighter pilots of the era, he preferred the latter.
In December 1952, Aldrin was assigned to the 16th Fighter-Interceptor Squadron, which was part of the 51st Fighter-Interceptor Wing. At the time it was based at Suwon Air Base, about south of Seoul, and was engaged in combat operations as part of the Korean War. During an acclimatization flight, his main fuel system froze at 100percent power, which would have soon used up all his fuel. He was able to override the setting manually, but this required holding a button down, which in turn made it impossible to also use his radio. He barely managed to make it back under enforced radio silence. He flew 66 combat missions in F-86 Sabres in Korea and shot down two MiG-15 aircraft.
The first MiG-15 he shot down was on May 14, 1953. Aldrin was flying about south of the Yalu River, when he saw two MiG-15 fighters below him. Aldrin opened fire on one of the MiGs, whose pilot may never have seen him coming. The June 8, 1953, issue of Life magazine featured gun camera footage taken by Aldrin of the pilot ejecting from his damaged aircraft.
Aldrin's second aerial victory came on June 4, 1953, when he accompanied aircraft from the 39th Fighter-Interceptor Squadron in an attack on an airbase in North Korea. Their newer aircraft were faster than his and he had trouble keeping up. He then spotted a MiG approaching from above. This time, Aldrin and his opponent spotted each other at about the same time. They went through a series of scissor maneuvers, attempting to get behind the other. Aldrin was first to do so, but his gun sight jammed. He then manually sighted his gun and fired. He then had to pull out, as the two aircraft had gotten too low for the dogfight to continue. Aldrin saw the MiG's canopy open and the pilot eject, although Aldrin was uncertain whether there was sufficient time for a parachute to open. For his service in Korea, he was awarded two Distinguished Flying Crosses and three Air Medals.
Aldrin's year-long tour ended in December 1953, by which time the fighting in Korea had ended. Aldrin was assigned as an aerial gunnery instructor at Nellis. In December 1954 he became an aide-de-camp to Brigadier General Don Z. Zimmerman, the Dean of Faculty at the nascent United States Air Force Academy, which opened in 1955. That same year, he graduated from the Squadron Officer School at Maxwell Air Force Base in Alabama. From 1956 to 1959 he flew F-100 Super Sabres equipped with nuclear weapons as a flight commander in the 22nd Fighter Squadron, 36th Fighter Wing, stationed at Bitburg Air Base in West Germany. Among his squadron colleagues was Ed White, who had been a year behind him at West Point. After White left West Germany to study for a master's degree at the University of Michigan in aeronautical engineering, he wrote to Aldrin encouraging him to do the same.

Through the Air Force Institute of Technology, Aldrin enrolled as a graduate student at the Massachusetts Institute of Technology in 1959 intending to earn a master's degree. Richard Battin was the professor for his astrodynamics class. Two other USAF officers who later became astronauts, David Scott and Edgar Mitchell, took the course around this time. Another USAF officer, Charles Duke, also took the course and wrote his 1964 master's degree at MIT under the supervision of Laurence R. Young.
Aldrin enjoyed the classwork and soon decided to pursue a doctorate instead. In January 1963, he earned a Sc.D. degree in astronautics. His doctoral thesis was Line-of-Sight Guidance Techniques for Manned Orbital Rendezvous, the dedication of which read: "In the hopes that this work may in some way contribute to their exploration of space, this is dedicated to the crew members of this country's present and future manned space programs. If only I could join them in their exciting endeavors!" Aldrin chose his doctoral thesis in the hope that it would help him be selected as an astronaut, although it meant foregoing test pilot training, which was a prerequisite at the time.
After completing his doctorate, Aldrin was assigned to the Gemini Target Office of the Air Force Space Systems Division in Los Angeles, working with the Lockheed Aircraft Corporation on enhancing the maneuver capabilities of the Agena target vehicle which was to be used by NASA's Project Gemini. He was then posted to the Space Systems Division's field office at NASA's Manned Spacecraft Center in Houston, where he was involved in integrating Department of Defense experiments into Project Gemini flights.
