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. Two versions of the Sputnik were built, the Sputnik-PS (GRAU index 8K71PS), which ...
Sputnik 1. Sputnik (Спутник, Russian for "satellite" [1]) is a spacecraft launched under the Soviet space program."Sputnik 1", "Sputnik 2" and "Sputnik 3" were the official Soviet names of those objects, and the remaining designations in the series ("Sputnik 4" and so on) were not official names but names applied in the West to objects whose original Soviet names may not have been known ...
2.5–5.0 kilometers (max. deviation 10 kilometers) The R-7 Semyorka (Russian: Р-7 Семёрка), officially the GRAU index 8K71, was a Soviet missile developed during the Cold War, and the world's first intercontinental ballistic missile. The R-7 made 28 launches between 1957 and 1961. A derivative, the R-7A, was operational from 1960 to 1968.
Spacecraft. Sputnik 2 was a 4-metre-high (13 ft) cone-shaped capsule with a base diameter of 2 metres (6.6 ft) that weighed around 500 kilograms (1,100 lb), though it was not designed to separate from the rocket core that brought it to orbit, bringing the total mass in orbit to 7.79 tonnes (17,200 lb).

Sputnik 1 (/ ˈspʌtnɪk, ˈspʊtnɪk /, 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. It sent a radio signal back to Earth for three weeks ...
The first small-lift launch vehicle was the Sputnik rocket, launched by the Soviet Union, which was derived from the R-7 Semyorka ICBM. On 4 October 1957, the Sputnik rocket was used to perform the world's first satellite launch, placing the Sputnik 1 satellite into a low Earth orbit.

This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list includes all upcoming rockets. For the simple list of all conventional ...
Sputnik 3. Sputnik 3 (Russian: Спутник-3, Satellite 3) was a Soviet satellite launched on 15 May 1958 from Baikonur Cosmodrome by a modified R-7/SS-6 ICBM. The scientific satellite carried a large array of instruments for geophysical research of the upper atmosphere and near space. Sputnik 3 was the only Soviet satellite launched in 1958.
