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 .

Sputnik 1 was the first artificial Earth satellite ever launched. On October 4, 1957, the USSR launched Sputnik 1 into orbit and received transmissions from it. [86] Sputnik 1 was designed to be the forerunner for multiple satellite missions. The technology constantly underwent upgrades as the weight of satellites increased.
Each satellite weighs 2,030 kg (4,480 lb) at launch and 1,080 kg (2,380 lb) once on orbit. [14] The first attempted launch of a Block IIR satellite failed on 17 January 1997 when the Delta II rocket exploded 12 seconds into flight.
The Vanguard rocket [1] was intended to be the first launch vehicle the United States would use to place a satellite into orbit. Instead, the Sputnik crisis caused by the surprise launch of Sputnik 1 led the U.S., after the failure of Vanguard TV-3, to quickly orbit the Explorer 1 satellite using a Juno I rocket, making Vanguard 1 the second successful U.S. orbital launch.
