ISRO successfully Tests India's Largest Cryogenic Engine For 400-Ton Rocket.
Indian Space Research Organisation (ISRO) successfully tested India’s largest Cryogenic engine. The Indigenously developed cryogenic engine is capable to launch four ton class satellites in Geosynchronous Orbit and this will be used in GSLV (Geosynchronous Satellite launch vehicle) Mark III rocket.
It was successfully Ground tested its cryogenic upper stage engine for GSLV Mark III at its liquid propulsion complex at Mahendragiri in Tirunelveli, Tamil Nadu.
India is now become 6th country to acquire this technology after two decades of hard work as the technology was denied to India by Russia under pressure from the US. Other countries which have this technology are Russia, USA, Japan, China and France.
About Cryogenic Engine:
'Cryogenic is the study of substances at very low temperature in which gases like nitrogen, hydrogen and oxygen become liquid at minus 150 degree or less.
'This is the reason we called this as cryogenics engine, which use liquid hydrogen and oxygen as fuel that are stored at minus 253 degrees and then ignited to burn at plus hundreds of degrees centigrade .
'Cryogenic Engine was first used by US in 1963. India took almost 20 years to develop Cryogenic Engine.
About Geo-Synchronous Orbit:
Geo-synchronous orbit is located 35,786 kilometers(22,236 miles) above Earth’s Equator which is ideal site for monitoring communication, weather, and surveillance.
