That's one small step for [a] man, one giant leap for mankind. &#8213Neil Armstrong

Armstrong became the first man to walk on the Moon, followed by Aldrin. Collins remained in orbit above the Moon.

Mission notes

• On July 20, while on the far side of the moon, the lunar module, called "Eagle," separated from the "Columbia". Collins remained aboard Columbia while Eagle, carrying Armstrong and Aldrin, descended to the surface.
• After a careful visual inspection, Eagle fired its engine and began its descent. During the descent to the lunar surface, the astronauts noticed that the intended landing site was rockier than surveillance photographs had indicated. Armstrong took manual control of the lunar module at that point, and guided it to a landing on a smoother patch of ground, later known as Tranquility Base.
• Six and a half hours after landing, Armstrong made his descent to the moon surface and made the famous statement: "That's one small step for [a] man, one giant leap for mankind." (Though he apparently dropped the "a", changing the meaning of the statement--some historians have been charitable and called this a radio communication failure rather than a simple mistake by Armstrong).
• After 21 hours and 36 minutes, Eagle fired its ascent engines and rendezvoused with the Columbia for the return flight. The astronauts returned to earth on July 24, welcomed as heroes.

The command module is displayed at the National Air and Space Museum, Washington, D.C. The lunar module was jettisoned on 21 July, 1969. Impact site of the lunar module on the Moon is unknown.
