The Dnepr rocket (Russian: Днепр, romanized: Dnepr; Ukrainian: Дніпро, romanized: Dnipró) was a space launch vehicle named after the Dnieper River. It was a converted ICBM 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.[2][3]
