ISRO successfully tests largest cryogenic engine for GSLV Mark III rocket
- Indian Space Research Organisation (ISRO) has successfully ground tested India’s largest indigenously developed Cryogenic Upper Stage engine for GSLV Mark III.
- It was tested for full 10 minutes at ISRO’s Liquid Propulsion Complex (ILPC) at Mahendragiri in Tirunelveli district of Tamil Nadu.
- The C25 stage is the most powerful upper stage so far developed by ISRO.
- It uses Liquid Oxygen and Liquid Hydrogen propellant combination stored at minus 253 degrees centigrade
- . The development of C25 cryogenic stage will provide ISRO capability to launch 4 ton class satellites in Geosynchronous Transfer Orbit (GTO), an altitude where satellites revolve in sync with Earth’s rotation.
- So far, the cryogenic engine consisting very complex technology has been developed only by Russia, US, France, China, Japan and India.
- This was last test in the series before going for actual GSLV Mark III rocket launch in April 2017 where engine will be put into actual use
- The GSLV Mark III rocket will be a successor to the GSLV Mark II which was first launched in 2001 and can carry a heavier payload than the Polar Satellite Launch Vehicle or PSLV.
