The '''Apollo 11''' mission was the first manned lunar landing. It was the fifth manned mission in the [[Apollo|Apollo program]].

<blockquote>''That's one small step for [a] man, one giant leap for mankind.''</blockquote>
:&#8213;Neil Armstrong

The mission was launched on 16 July 1969 with astronauts [[Neil Armstrong]], [[Michael Collins]] and  [[Buzz Aldrin]]. On July 20, Armstrong became the first man to walk on the Moon, followed by Aldrin. Collins remained in orbit above the Moon. The astronauts returned safely to earth four days later.

== Mission notes ==
* On July 20, while on the far side of the moon, the [[Apollo Lunar Module|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.
* On July 20 at 10:56 PM EDT, 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. 22 kg of lunar samples were collected. The astronauts returned to earth on July 24, welcomed as heroes. The splashdown point was 13 deg 19 min N, 169 deg 9 min W, 400 miles SSW of Wake Island and 24 km (15 mi) from the recovery ship USS Hornet.

==Crew==


*[[Neil Armstrong]], commander
*[[Michael Collins (astronaut)|Michael Collins]], command module pilot
*[[Buzz Aldrin]], lunar module pilot


==Post scriptum==
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.

The command module and its crew were flawlessly recovered by the aircraft carrier USS Hornet (CV-12). The ship is now open to the public as a museum in Alameda, CA.
