GSLV-Mark-III
Recently, Indian Space Research Organisation (ISRO) has successfully ground tested India’s first indigenously developed high thrust cryogenic rocket engine “C25” for the rocket GSLV-Mark-III in its Propulsion Complex at Mahendragiri in southern Tamil Nadu. This cryogenic engine of C25 Stage operates on Gas Generator Cycle using extremely low temperature propellants – Liquid Hydrogen (LH2) at 20 Kelvin (-253 deg C) and Liquid Oxygen (LOX) at 80K (-193 deg C). The GSLV-Mark-III rocket fitted with the cryogenic upper stage is expected to lift off 4-tonne class communication satellite in mid-2017.
