Small-lift launch vehicle

History

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. The US responded by attempting to launch the Vanguard rocket. However, the Vanguard TV3 launch attempt failed, with the 31 January 1958 launch of the Explorer 1 satellite using the Juno I rocket being the first successful US orbital launch. The Vanguard I mission was the second successful US orbital launch. This was the start of the space race.

Since the late 1950s, small-lift launch vehicles have continued launching payloads into orbits including LEO, Sun-synchronous orbit (SSO), and geostationary transfer orbit (GTO). Medium-lift launch vehicles, heavy-lift launch vehicles, and super heavy-lift launch vehicles have also been extensively developed but have not completely superseded small launch vehicles.
