This comprehensive guide aims to provide readers with a detailed understanding of the Kaganyaan mission’s recent milestone in human evaluation. From the intricacies of the CE20 cryogenic engine to ISRO’s commitment to safety and international collaboration, readers gain insights into the scientific, technological, and human aspects of India’s journey into crewed space exploration.

The Kaganyaan mission aims to send a three-person crew to a 400 km orbit for a three-day mission and return them safely to Earth.

The Indian Space Research Organization (ISRO) has successfully completed human evaluation of its CE20 cryogenic engine, giving a significant boost to India’s efforts to send humans to space under the Gaganyaan programme, an official said.

With the completion of the final round of ground qualification tests on February 13, 2024, ISRO has achieved a major milestone in the human evaluation of the CE20 cryogenic engine that will power the cryogenic stage of the human-evaluated LVM3 launch vehicle for the Kaganyaan mission.

will provide. ISRO said in a press release that the final test was the seventh in a series of vacuum ignition tests conducted at the High Altitude Test Facility at ISRO’s Propulsion Complex in Mahendragiri to simulate flight conditions.

“To qualify the CE20 engine for the human evaluation criteria, the four engines had to undergo 39 hot firing tests for a total of 8810 seconds against 6350 seconds,” ISRO said.

All ground qualification tests of the CE20 engine for the Kaganyan project have been successfully completed. Ground qualification tests for human evaluation of the CE20 engine include durability performance testing, endurance testing and performance evaluation at nominal operating conditions and thrust, mixture ratio and propellant tank pressure at nominal conditions.

What is Kaganayan Mission?

The Kaganyaan mission, targeted for launch in 2024-2025, aims to launch a three-member crew into a 400 kilometer orbit for a three-day mission, land in the waters of the Indian Ocean and return them safely to Earth.

ISRO has also completed acceptance testing of the aircraft engine it invented for the first unmanned Kaganyaan (G1) mission tentatively scheduled for the second quarter of 2024. This engine provides the vehicle’s human-rated LVM3 power at top level and has a thrust capacity of 19. Up to 22 tons with a specific impulse of 442.5 seconds.

Major projects of ISRO
ISRO aims to establish India’s own space station – the ‘Indian Space Station’ – by 2035. The second big goal is to send the first Indian to the Moon by 2040.
