Communication satellites

Signalers were among the first to receive practical benefits from the launch of satellites. The launch of satellite transponders into near-Earth orbit made it possible to solve the problem of stable all-weather communication in most of the inhabited territory as soon as possible. The first commercial satellite was precisely the communications satellite – Echo-2, launched by the United States in 1964 and which made it possible to organize the transmission of television programs from America to Europe without the use of cable lines. At the same time, its lightning-1 communications satellite was also created in the Soviet Union. After the deployment of the ground-based network of Orbita stations, all regions of our large country gained access to Central Television, and in addition, the problem of organizing reliable and high-quality telephone communications was solved. Lightning communications satellites were located in highly elliptical orbits with Continue reading

Achievements in space exploration

Many thousands of years ago, looking at the night sky, a man dreamed of flying to the stars. Billions of shimmering night luminaries made him carry away the thought into the boundless distances of the Universe, awakened the imagination, forced him to think about the secrets of the universe. Centuries passed, man gained ever greater power over nature, but the dream of flying to the stars remained as unrealizable as thousands of years ago. Legends and myths of all nations are full of stories about flying to the moon, the sun and the stars. The means for such flights offered by the folk fantasy were primitive: a chariot drawn by eagles, wings attached to the hands of a person.

In the 19th century, a fantastic story appeared by the writer Jules Verne “From a cannon to the moon”. The 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.
