Sputnik 1 (/ ˈ s p ʌ t n ɪ k, ˈ s p ʊ t n ɪ k /, Russian: Спутник-1, Satellite 1), sometimes referred to as simply Sputnik, was the first artificial Earth satellite.It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program.
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 into a low Earth orbit .

However, due to the weight of Soviet nuclear warheads, the R-7 possessed a significantly greater payload capacity than early U.S. ICBMs. This advantage made the R-7 suitable for space launch missions, giving the Soviet Union a substantial head start in the Space Race. An unmodified R-7 launched Sputnik 1, the world's first artificial satellite.
Oct. 4—66 years ago, on October 4, 1957, the Soviet Union launched the world into the space race after sending the first satellite, Sputnik 1, into orbit. Sputnik 1 weighed around 184 pounds and ...
In order for the probe to be successful in space, a mechanism needed to be developed to get the object outside Earth's atmosphere. The propulsion system that was utilized to send Sputnik 1 into space was dubbed the R-7. The design of the R-7 was also unique for its time and allowed for the Sputnik 1 launch to be a success.
Fifty-eight years ago today on October 4, 1957, Sputnik was launched into orbit by the Soviet Union.
