The first man to walk on the moon

From Wikipedia, the free encyclopedia

Apollo 11 was the spaceflight that landed the first humans on the Moon, Americans Neil Armstrong and Buzz Aldrin, on July 20, 1969, at 20:18 UTC. Armstrong became the first to step onto the lunar surface six hours later on July 21 at 02:56 UTC. Armstrong spent about two and a half hours outside the spacecraft, Aldrin slightly less, and together they collected 47.5 pounds (21.5 kg) of lunar material for return to Earth. A third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit until Armstrong and Aldrin returned to it just under a day later for the trip back to Earth.

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 (CM) with a cabin for the three astronauts, and the only part that landed back on Earth; a Service Module (SM), which supported the Command Module with propulsion, electrical power, oxygen, and water; and a Lunar Module (LM) for landing on the Moon. After being sent toward the Moon by the Saturn V’s upper stage, the astronauts separated the spacecraft from it and traveled 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. 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 U.S. Congress: “before this decade is out, of landing a man on the Moon and returning him safely to the Earth.”[7]

After the crew of Apollo 10 named their spacecraft Charlie Brown and Snoopy, assistant manager for public affairs Julian Scheer wrote to Manned Spacecraft Center director George M. Low to suggest the Apollo 11 crew be less flippant in naming their craft. During early mission planning, the names Snowcone and Haystack were used and put in the news release,[10] but the crew later decided to change them.

The Command Module was named Columbia after the Columbiad, the giant cannon shell “spacecraft” fired by a giant cannon (also from Florida) in Jules Verne’s 1865 novel From the Earth to the Moon.[11] The Lunar Module was named Eagle for the national bird of the United States, the bald eagle, which is featured prominently on the mission insignia.

Insignia

The Apollo 11 mission insignia was designed by Collins, who wanted a symbol for “peaceful lunar landing by the United States”. He chose an eagle as the symbol, put an olive branch in its beak, and drew a lunar background with the Earth in the distance. NASA officials said the talons of the eagle looked too “warlike” and after some discussion, the olive branch was moved to the claws. The crew decided the Roman numeral XI would not be understood in some nations and went with “Apollo 11”; they decided not to put their names on the patch, so it would “be representative of everyone who had worked toward a lunar landing”.[12]

All colors are natural, with blue and gold borders around the patch. When the Eisenhower dollar coin was released a few years later, the patch design provided the eagle for its reverse side.[13] The design was retained for the smaller Susan B. Anthony dollar which was unveiled in 1979, ten years after the Apollo 11 mission.[citation needed]

Mementos

Neil Armstrong’s personal preference kit carried a piece of wood from the Wright brothers‘ 1903 airplane’s left propeller and a piece of fabric from its wing,[14] along with a diamond-studded astronaut pin originally given to Deke Slayton by the widows of the Apollo 1 crew. This pin had been intended to be flown on Apollo 1 and given to Slayton after the mission but following the disastrous launch pad fire and subsequent funerals, the widows gave the pin to Slayton and Armstrong took it on Apollo 11.[15]
