Buzz Aldrin

Buzz Aldrin 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 the 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, he is the last surviving Apollo 11 crew member. Following Jim Lovell's death in 2025, Aldrin became the oldest living astronaut.

Apollo 11 was the American spaceflight that first landed humans on the Moon, and the fifth crewed mission of NASA's Apollo program. The mission was crewed by Commander Neil Armstrong, Command Module Pilot Michael Collins, and Lunar Module Pilot Edwin "Buzz" Aldrin, all of whom were on their second and final spaceflight.

Armalcolite () is a titanium-rich mineral with the chemical formula (Mg,Fe2+)Ti2O5. It was first found at Tranquility Base on the Moon in 1969 during the Apollo 11 mission, and is named for Armstrong, Aldrin and Collins, the three Apollo 11 astronauts. Together with tranquillityite and pyroxferroite, it is one of three new minerals that were discovered on the Moon. Armalcolite was later identified at various locations on Earth and has been synthesized in the laboratory. (Tranquillityite and pyroxferroite were also later found at various locations on Earth). The synthesis requires low pressures
