The Dnepr rocket is a space launch vehicle named after the Dnieper River. Is based on the R-36MUTTH Intercontinental ballistic missile (ICBM) - called the SS-18 Satan by NATO - used for launching artificial satellites into orbit, operated by launch service provider ISC Kosmotras. The first launch, on April 21, 1999, successfully placed UoSAT-12, a 350 kg demonstration mini-satellite, into a 650 km circular Low Earth orbit. On a typical mission the Dnepr deploys a larger main payload and a secondary payload of Miniaturized satellites and CubeSats.
