Rokot

Space Exploration
  • Russian three-stage liquid propellant rocket based on the SS-19 Intercontinental Ballistic Missile, capable of launching a 2 140-kg payload into low Earth orbit from the Plesetsk Cosmodrome in northern Russia. The expendable launch vehicle is particularly suitable for lofting small and medium-sized spacecraft into Sun-synchronous, near-polar and highly inclined orbits, or several satellites at once to form satellite constellations. The overall launch vehicle length is 29 m and the launch mass is 107 metric tonnes. Following two sub-orbital missions (20 November 1990 and 20 December 1991), Rokot finally launched an amateur radio satellite into orbit on 26 December 1994. Rokot launches from Plesetsk began on 16 May 2000. On 13 October 2017 Rokot made its final flight by carrying the European Space Agency’s Sentinel-5 Precursor safely into orbit. It marked the 27th launch from Plesetsk; where there have been 24 successes, two failures (including the loss of ESA’s Cryosat), and one partial failure. Rokot is now being phased out in favour of the newer Angara and Soyuz boosters.
