Now that Indian Space Research Organisation (ISRO) has mastered the long-denied cyrogenic technology, it is bracing up for more GSLV launches riding high on the successful launch of GSLV-F05, which is the tenth flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV), launching INSAT-3DR, an advanced weather satellite, weighing 2,211 kg into a Geostationary Transfer Orbit (GTO).

GSLV is designed to inject two 2.5 Tonne class of satellites into GTO and the launch took place from the Second Launch Pad at Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota on September 08, 2016.
GSLV-F05 flight is significant since it is the first operational flight of GSLV carrying Cryogenic Upper Stage (CUS), which is indigenously developed. It may be recalled that ISRO faced US sanctions two decades ago owing to Pokhran Nuclear Tests, considerably delaying its program on cryogenic engines.
GSLV-F05 vehicle is configured with all its three stages including the CUS similar to the ones successfully flown during the previous GSLV-D5 and D6 missions in January 2014 and August 2015, which had placed GSAT-14 and GSAT-6 satellites carried on-board in the intended GTOs accurately.
Indian Space Research Organisation (ISRO) has two more GSLV-MkII missions scheduled to be launched this year, while it is working on developing a C-25 engine that will have doubled power for liftoff of heavy satellites in the range of over 4,000kg.
With Friday’s cryogenic rocket launch, India has accomplished another milestone joining the club of five other nations — US, Russia, France, Japan and China — which have successfully developed and used the cryogenic engine technology to lift off heavy satellites.
The GSLV was primarily developed to launch INSAT class of satellites into Geosynchronous Transfer Orbits. GSLV is a three stage launcher that uses one solid rocket motor stage, one Earth storable liquid stage and one cryogenic stage. The most recent flight of GSLV, the GSLV-D5, placed GSAT-14 into its planned orbit and marked the first successful flight of the indigenous cryogenic stage.
