The 49th anniversary of the mission that brought the man to the moon, Apollo 11, is celebrated

Commanded by Neil A. Armstrong, this American giant landed on the lunar surface on July 20, 1969. His task, indicated by then-president Jon Fitzgerald Kennedy, was to be the first country to march on this natural satellite

On July 16, 1969, a giant 110-foot-tall American Saturn V rocket was leaving the Kennedy Space Center, with the aim that the human being walked on the moon for the first time. Astronauts Neil A. Armstrong were traveling aboard the spacecraft as a commander; Michael Collins, pilot of the control module; and Edwin E. Aldrin Jr., pilot of the lunar module

Apollo 11 reached the moon four days later, on July 20 . While astronauts Armstrong and Aldrin were descending into the lunar module 'Eagle & # 39; to explore the sea of ​​the region Tranquility of the Moon The astronaut Collins remained with the command and service modules "Columbia" in lunar orbit

The Apollo project began about a year ago from a decade ago, in 1960, with the intention of the United States Space Agency (NASA) to fly over the moon during an inhabited mission, and, a year later Plans were amended by the announcement of the country's president, Jon Fitzgerald Kennedy, as EE. UU It would be the first country to send a man on the terrestrial satellite. Even so, Kennedy could not see the program that he promoted himself when he was badbadinated in 1963, and it was under Richard Nixon when the Apollo XI mission was successfully completed the trip.

During the first human incursion into the As a natural satellite, the astronauts placed an American flag and a commemorative plaque and, in addition to taking pictures, installed a laser reflector, a seismograph and a screen to measure the 39, solar wind intensity at the surface, according to NASA

. They also took advantage of the expedition to collect samples of lunar soil (fragments of earth and rock) that they then brought back to Earth to conduct research and explore a part of the region where they landed . The badysis of the lunar substrate collected during the expedition revealed, among other things, that the satellite that orbits the Earth is made of materials identical to those that can be found on Earth, at following a fusion or meteorites, and that Like this planet, its interior is formed by strata and for a time it was in a fluid state.

The Apollo XI was, however, not the first expedition to reach the moon. On the one hand, a previous NASA mission, Apollo X, had succeeded in May in sending a vessel inhabited by Thomas P. Stafford, John W. Young and Eugene A. Cernan, who had twice toured the Selenite satellite and have managed to return In addition, already a decade earlier, in 1959, the Soviet Union had been the first to place a probe on the Moon with the project Luna2, and a crew of six turtles, mushrooms and moss were the first living beings in orbit around the satellite, with the Soviet spacecraft Zond 5, which was the first to surround and return to Earth

Following the success of the Apollo XI mission, five other NASA program shipments managed to bring a total of nine people to the satellite, ten relying on the two pioneers (Collins did not have an opportunity to walk on the moon, since he was in the control module): Apollo 12, 14, 15, 16 and 17. The mission Apollo 18 was unable to reach his goal because of the tank's liquid oxygen tank service, but the crew returned safe and sound.
