The Sputnik rocket was an uncrewed orbital carrier rocket designed by Sergei Korolev in the Soviet Union , derived from the R-7 Semyorka ICBM . On 4 October 1957, it was used to perform the world's first satellite launch, placing Sputnik 1 low Earth orbit .
Two versions of the Sputnik were built, the Sputnik-PS (GRAU index 8K71PS), which was used to launch Sputnik 1 and later Sputnik 2 Sputnik 3 [1]
A later member of the R-7 family , the Polyot , used the same configuration as the Sputnik rocket, but was constructed from Voskhod components. Because of the similarity, the Polyot was sometimes known as the Sputnik 11A59.
