An anonymous reader writes "The Indian Space Research Organisation (Isro) today successfully launched its heavy-duty rocket — the Geo Synchronous Satellite Launch vehicle (GSLV). The communication satellite, GSAT-14 was launched from Isro's spaceport at Sriharikota, about 80 km from Chennai. ISRO had to develop the cryogenic technology from scratch after the United States prevented Russia from transferring the technology to the India in 1993. Today's successful launch marks the culmination of a 20 year effort to develop the engine."
