If you like my designs, like them and follow me, and if you have printed my design, take a picture of it. and give them over the comments. The reason I am making a Russian satellite is because I find it very easy. (My project has no relevance to the current political situation.) Sputnik 1, the first artificial satellite of the Earth. Launched by the USSR on October 4, 1957 at 19:28:34 universal time. Along with three other satellites in the Sputnik series, it was a Soviet contribution to the International Geophysical Year. The launch of Sputnik 1 into orbit marked the beginning of the space race between the USSR and the United States. Sputnik's visual and radio observations have been conducted all over the world. The ship's hull was a sphere 580 mm in diameter [3] (for both aesthetic and engineering reasons, Korolev insisted that the Sputnik be spherical, although one of his earlier designs had a conical shape [2]) and was made of a high-reflective aluminum alloy with a thickness of 2 mm. It was hermetic and filled with nitrogen, the pressure of which was monitored - the loss of gas would indicate a meteoroid impact, which would be the first registration of such a celestial body. However, this event did not take place. Four antennas, 2.4-2.9 m long, were attached to the body at an angle of 35 °. It allowed for the first time in history to measure the density of the upper atmosphere (based on changes in orbit parameters) and obtain data on the spread of radio signals in the ionosphere , check the theoretical predictions and basic technical assumptions (the problem of introducing into the orbit, thermal phenomena) [3].
