Hi My Friends: AL VUELO DE UN QUINDE EL BLOG.,
Apollo 11 was the spaceflight which landed the first humans, Americans Neil Armstrong and Buzz Aldrin, on the Moon on July 20, 1969, at 20:18 UTC.
Armstrong became the first to step onto the lunar surface 6 hours later
on July 21 at 02:56 UTC. A third member of the mission, Michael Collins,
remained alone in lunar orbit until they returned from the surface
about 15 hours later. All 3 returned to Earth safely after travelling in
space for 8 days.
Launched by a Saturn V rocket from Kennedy Space Center in Merritt Island, Florida on July 16, Apollo 11 was the fifth manned mission of NASA's Apollo program. The Apollo spacecraft had three parts: a Command Module with a cabin for the three astronauts which was the only part which landed back on Earth; a Service Module containing propulsion, electrical power, oxygen and water; and a Lunar Module
for landing on the Moon. After being sent to the Moon by the Saturn V's
upper stage, the astronauts separated the spacecraft from it and
travelled for three days until they entered into lunar orbit. Armstrong
and Aldrin then moved into the Lunar Module and landed in the Sea of Tranquility.
They stayed a total of about 21½ hours on the lunar surface, including
about 2½ hours outside the spacecraft. After lifting off in the upper
part of the Lunar Module and rejoining Collins in the Command Module,
they returned to Earth and landed in the Pacific Ocean on July 24.
Broadcast on live TV to a world-wide audience, Armstrong stepped onto
the lunar surface and described the event as "one small step for [a]
man, one giant leap for mankind." Apollo 11 effectively ended the Space Race and fulfilled a national goal proposed in 1961 by the late U.S. President John F. Kennedy in a speech before the United States Congress, "before this decade is out, of landing a man on the Moon and returning him safely to the Earth."[3] W
