GSLV Mk II - F14

Company: ISRO

The Indian Space Research Organization (ISRO) manages a type of expendable launch systems known as the Geosynchronous Satellite Launch Vehicle (GSLV). Since 2001, fifteen launches have made use of GSLV. Major components of the Geospace Shuttle Launch Vehicle (GSLV) consist of the liquid-fueled Vikas engine and the S125/S139 solid rocket booster, which are already proven in the Polar Satellite Launch Vehicle (PSLV) launch vehicles. Owing to the thrust necessary to propel the satellite into a geostationary transfer orbit (GTO), India lacked the technological know-how to construct a LOX/LH2 cryogenic engine for the third stage.
