Giant leap into space exploration

How did the work of the first American expedition on the lunar surface begin? Immediately after the ship landed on the plain of the lunar Sea of ​​Tranquility, the Apollo 11 commander Neil Armstrong told the Mission Control Center via radio: “Houston, here is Tranquility Base. The eagle has landed ”(Eagle,“ Eagle ”, called the lunar ship,“ landed ”meant landing on the lunar firmament,“ earth ”, and the landing point was called the Base of Tranquility after the vast lunar plain – Sea of ​​Tranquility).

After that, the astronauts checked all the systems of the lunar module in case of an unexpected launch. Next, according to the plan, there was a dream lasting 4 hours. And here the astronauts in violation of the program asked permission to begin access to the moon immediately. It has been received. Barely touching the lunar surface with the left boot of his Continue reading

Man on the moon

Work on this program began in the USA in the late 60s. It was decided to carry out a man’s flight to the moon and his successful return to Earth over the next ten years. In the summer of 1962, after lengthy discussions, they came to the conclusion that the most efficient and reliable way is to place the complex in the command and computing module, which includes the command and auxiliary modules, and the lunar landing module into the lunar orbit. The first priority was the creation of a launch vehicle capable of introducing at least 300 tons into low Earth orbit and at least 100 tons into low Earth orbit. At the same time, the development of the Apollo spacecraft, designed for the flight of American astronauts to the moon, was underway. In February 1966, the Apollo was tested in an unmanned version.

Moon exploration

It is not surprising that the first flight of the spacecraft above Earth orbit was directed to the moon. This honor belongs to the Soviet spacecraft Luna-l, which was launched on January 2, 1958. In accordance with the flight program, after a few days it passed at a distance of 6,000 kilometers from the surface of the moon. Later that same year, in mid-September, a similar Moon series device reached the surface of the Earth’s natural satellite.
A year later, in October 1959, the Luna-3 automatic apparatus, equipped with apparatus for photographing, surveyed the far side of the Moon (about 70% of the surface) and transmitted its image to Earth. The device had an orientation system with sensors of the Sun and the Moon and jet engines running on compressed gas, Continue reading
