India successfully tested the cryogenic engine for the heavy rocket that would launch the country’s second moon mission on January 3, 2019, the space agency said on Friday.<\/p>\n
“The cryogenic engine of the Geo Satellite Launch Vehicle (GSLV MK-III) in the upper stage has been tested for the Chandrayaan-2 Mission,” said the state-run Indian Space Research Organisation (ISRO) in a statement here.<\/p>\n
The crucial test was conducted on Thursday for 25 seconds at the space agency’s propulsion complex in Tamil Nadu’s Mahendragiri, 685km southwest of Chennai.<\/p>\n
“The upper stage of the heavy rocket is powered by cryogenic engine, which develops a nominal thrust of 186.36 kN (kilo Newton) with a specific impulse of 442 seconds in a vacuum,” noted the statement.<\/p>\n
The supercooled engine operates on gas generator cycle using liquid oxygen and hydrogen (LOX & LH2) or oxidizer.<\/p>\n
\u00a0“The test demonstrated steady state operation of engine,” said the statement.<\/div>\n
The flight acceptance hot test of the cryo was performed at the high-altitude test facility in the complex.<\/p>\n
“The performance of all engine subsystems was observed to be normal during the hot test,” added the statement.<\/p>\n
The second lunar mission will be launched from the rocketport at Sriharikota in Andhra Pradesh, about 90km northeast of Chennai, with a lander and rover a decade after the first moon mission in October 2008 around its orbit.<\/p>\n
