astronaut career

Armstrong was not eligible to become one of the program's astronauts. Mercury, for in it only military personnel were allowed for such a function. However, in 1960, he was selected as a consultant and later invited to act as one of the pilots and engineers on the project. X-20 Dyna Sound, whose intention was the production of a space plane that could be used in recon missions, space rescue, satellite maintenance, bombings etc.

In 1962, NASA announced that it would receive the application of more astronauts, only this time for the program Gemini, and that in this project qualified civilian pilots for the mission would be accepted. Armstrong applied for the job, however, his application arrived a week late. Luckily, a former co-worker saw his application and placed it with the other applications, before anyone noticed the irregularity. On September 13, 1962, civil engineer Neil Armstrong was called to join NASA's astronaut team..

Neil Armstrong and the Apollo 11 program

On January 27, 1967, the astronauts Neil Armstrong, Gordon Cooper, Richard Gordon and Jim Lovell they were meeting in Washington for the signing of the Outer Space Treaty. At the time, the astronauts were informed about the Apollo 1 mission failure, which led to the death of the three crew members on the ship.

On April 5, 1967, 18 astronauts from the Apollo program were brought together to discuss the cause of the accident suffered by the crew of the spacecraft launched by the mission. Apollo 1. At that meeting, according to those present, it was stated that the first men who would reach the Moon were in that room.

Despite this, Armstrong did not show any reaction to the phrase, for him this was natural, since the veterans of the Gemini project were the only people in the world able to carry out the missions to the Moon.

In 1968, DonaldSlayton, astronaut and also NASA manned flight supervisor, offered Neil Armstrong the post of commander of the Apollo 11 mission. At the time, the spacecraft Apollo 8 it was orbiting the Moon. A few days later, the crew of the Apollo 11 was officially released and was composed of: Neil Armstrong, Buzz Aldrin and Michael Collins.

During a meeting with the directors of the Apollo 11 mission in March 1969, it was decided that Armstrong would be the first man to set foot on the moon. The directors' justification was the lunar module cabin project eagle, whose disposition would make it difficult for the pilot, Buzz Aldrin, to leave.

The decision was controversial, as Aldrin tried several times to change the landing schedule so that he could be the first man to set foot on the moon. However, the program directors stayed with the project as it was conceived.

In July 16, 1969, at 1:00 pm: 32 min UTC, the rocket Saturn V launched the Apollo 11 spacecraft towards the moon. During the landing, Armstrong realized that the lunar module was falling at a speed greater than planned and could therefore fall many kilometers from its landing site. So he took semi-manual control of the Eagle module and was able to safely land it when he there was only 20 seconds of fuel left.

A few hours after landing, Armstrong emerged from the interior of the lunar module, taking his first step on the Lua, and uttered his famous phrase, which was broadcast live to about 530 million spectators:

It's a small step for a man, a big step for humanity.”

Even today there is a controversy about the phrase spoken by Armstrong. This controversy is based around the quoted phrase of the astronaut, said right after having stepped on the Moon. While delivering it, Armstrong is believed to have forgotten to use the article “one” before “man” as he could not be heard on the broadcast. Despite the controversy, today, it is believed that the sentence was correctly uttered and that the mistake was due to the technological limitations of the transmission system used at the time.

About 20 minutes after Upon Armstrong's exit, Aldrin exited the interior of the Lunar Module. Along with the first one, he installed several experiments that are present on the Moon's surface to this day. Armstrong hoisted a american flag and left one he scorescommemorative.

Astronauts' time outside the Eagle has been reduced to a few hours due to the extremely high surface temperature of the Sunlit Moon. However, while this side can reach 127º C, some regions on the dark side of the Moon can reach -247º C.

After a little more than 21 hours on the surface from the satellite, the astronauts took off towards the command module, which was in orbit. Aldrin and Armstrong landed in the Pacific Ocean, on July 24, 1969, after a trip that lasted about eight days

Neil Armstrong retired after the Apollo 11 mission. In 1971, the astronaut became teacher and ministered until the year 1979. Even as an old man, he remained active, participating in groups that studied subjects such as aeronautics and space travel. The first man to set foot on the moon died in day August 25, 2012, at 82 years of age.

Astronauts who set foot on the moon

After Neil Armstrong and Buzz Aldrin, more ten astronauts stepped on the lunar surface. All these astronauts were from the Apollo program, that is, in all, 12 people already stepped on the surface of our natural satellite.

Although six manned missions to the Moon were carried out, with three astronauts each, in all of them, one of the astronauts remained in orbit around the Moon, in the command module.
