At 9:32 a.m. on July 16, 1969, NASA's Apollo 11 spacecraft was launched by a Saturn V rocket from the Kennedy Space Center in Florida. On board were astronauts Neil Armstrong, Buzz Aldrin and Michael Collins. Four days later, on July 20, they would become the first men to land on the moon.

Aldrin is photographed by Armstrong inside Apollo 11's lunar module, just prior to the moon landing. In orbit, Aldrin later took what would become known as the world's first space selfie. NASA
Aldrin is photographed on the moon after Armstrong went first and called it "one small step for man, one giant leap for mankind." Armstrong and Aldrin explored the Sea of Tranquility region of the moon. Meanwhile, Collins remained inside the command module for the duration of the mission. NASA

The astronauts were received by the President from their mobile quarantine unit, which was thought to help prevent the spread of contagions caught on the moon. The quarantine practice was discontinued a couple years later after Apollo 14's mission. Popperfoto/Getty Images
