The most famous first artificial Earth satellite, also known as PS-1 (the simplest satellite 1), was developed in OKB-1 (now RSC Energia). Designing the satellite was the final part of a long and hard process for constructing and fine-tuning the world’s first carrier missile, capable of bringing the satellite into orbit. Such rocket, bearing the name P-7 was designed and tested in the factory conditions between 1955 and 1956. Only after that, the order was given to develop an artificial satellite. The works were carried out from November 1956 to September 1957, in parallel with the test runs of R-7. After a series of unsuccessful test launches, on August 21, 1957, the missile was successfully launched: it started from Kazakhstan, went through the whole flight and dropped at the site in Kamchatka. Once the bench tests of «Sputnik 1» were completed, it was decided to launch it into space. The legendary event happened late in the evening of October 4, 1957. The satellite weighing 83.6 kilograms entered the elliptical orbit after 295 seconds, and after 20 seconds after the separation of the central unit, it transmitted its signal, which could be heard on two frequencies by all radio amateurs in the world. The launch of Sputnik marked the beginning of the era of space exploration, and the date of October 4 become memorable to the entire world. «Sputnik 1» orbited for 92 days and burned up in the upper atmosphere. During its flight, it completed 1,440 orbits of the Earth and traveled for 60 million kilometers.
