One of the first human beings to set foot on the moon is celebrating his birthday this weekend.
Apollo 11 astronaut Buzz Aldrin turned 89 on Sunday.
Aldrin and Neil Armstrong became the first human to set foot on the moon on July 20, 1969, as part of the Apollo 11 mission.
Aldrin was born in New Jersey and attended the US Military Academy after high school. After graduation, Aldrin joined the Air Force. He flew 66 combat missions in Korea and completed a tour of duty in Germany before returning to school to earn his Doctorate of Science in Astronautics from MIT.
In 1966, Aldrin took part in the Gemini 12 orbital flight mission. During the mission, Aldrin completed the first successful spacewalk in the world and took the first space selfie.
Just a few years later, about 600 million people watched him set foot on the moon.
