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
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
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.
