Apollo 11 was the spaceflight that landed the first humans on Earth's Moon on July 20, 1969 (20:17:40 UTC). The mission, carried out by the United States, is considered a major accomplishment in the history of space exploration.
Launched from Florida on July 16, the fifth manned mission, and the third lunar mission of NASA's Apollo program, was crewed by Commander Neil Armstrong, Command Module Pilot Michael Collins, and Lunar Module Pilot Edwin "Buzz" Aldrin, Jr. On July 20, Armstrong and Aldrin landed in the Sea of Tranquillity and on July 21 became the first humans to walk on the Moon. Their landing craft, Eagle, spent 21 hours and 31 minutes on the lunar surface while Collins orbited above in the command ship, Columbia.[2] The three astronauts returned to Earth with 47.5 pounds (21.5 kg) of lunar rocks and landed in the Pacific Ocean on July 24.
Apollo 11 fulfilled U.S. President John F. Kennedy's goal of reaching the Moon before the Soviet Union by the end of the 1960s, which he had expressed during a 1961 mission statement before the United States Congress: "I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth."[3]
Five additional Apollo missions landed on the Moon from 1969 to 1972.

The Launch
In President Kennedy's speech to Congress, on May 25, 1961, he expressed a concern that the United States was falling behind the Soviet Union in technology and prestige. He challenged the nation to put a man on the moon before the end of the decade.
On July 16, 1969, the Apollo 11 launched from the Kennedy Space Center.
The Moon Landing
On July 20, 1969, Commander Neil Armstrong became the first man on the moon. He said the historic words, "That's one small step for a man, one giant leap for mankind."
A camera in the Lunar Module provided live television coverage as Neil Armstrong climbed down the ladder to the surface of the moon.
The Lunar Module "Eagle" consisted of two parts: the descent stage and the ascent stage. The descent state provided the engine used to land on the moon. It had four legs, a storage area for experimental gear, and a ladder for the crew to climb down to the moon's surface. The descent module also served as the launch platform for the ascent module when it came time to leave.
The ascent module carried the crew back to the Command Service Module.
Walking on the Moon
To walk on the moon's surface, the astronauts needed to wear a space suit with a back mounted, portable life support system. This controlled the oxygen, temperature and pressure inside the suit.
On the surface, the astronauts had to get used to the reduced gravity. They could jump very high compared to on Earth.The crew spend a total of two and a half hours on the moon's surface. While on the moon's surface, the performed a variety of experiments and collected soil and rock samples to return to Earth.
An American flag was left on the moon's surface as the reminder of the accomplishment.
Driving on the Moon
In later moon landings, the astronauts used the Lunar Rover vehicle to help explore more of the moon's surface. 
Orbiting
| The Command Service Module "Columbia" consisted of two parts. The Command Module is the cone at the top, or front in this picture. The Command Module held the three man crew. It was the control center during the mission. It also was the re-entry vehicle for returning back to Earth. The Service Module at the bottom, or back in this picture, provided the propulsion and maneuvering capability for the space craft. |  |
