Major milestone: Cryogenic engine for Gaganyaan missions now human-rated, says ISRO
Bengaluru (PTI): ISRO has accomplished a major milestone in the human rating of its CE20 cryogenic engine that powers the cryogenic stage of the human-rated LVM3 launch vehicle for Gaganyaan human spaceflight missions, with the completion of the final round of ground qualification tests.
"ISRO's CE20 cryogenic engine is now human-rated for Gaganyaan missions," the space agency said on 'X" on Wednesday.
Rigorous testing demonstrates the engine's mettle, it said, adding the CE20 engine identified for the first uncrewed flight LVM3 G1 also went through acceptance tests.
The February 13 final test was the seventh of a series of vacuum ignition tests carried out at the High Altitude Test Facility at ISRO Propulsion Complex, Mahendragiri, to simulate flight conditions, it said.
The ground qualification tests for the human rating of the CE20 engine involved life demonstration tests, endurance tests and performance assessment under nominal operating conditions as well as off-nominal conditions with respect to thrust, mixture ratio and propellant tank pressure, it said.
All the ground qualification tests of the CE20 engine for the Gaganyaan programme have been successfully completed, ISRO said.
In order to qualify the CE20 engine for human rating standards, four engines have undergone 39 hot firing tests under different operating conditions for a cumulative duration of 8,810 seconds against the minimum human rating qualification standard requirement of 6,350 seconds, according to ISRO.
ISRO has also successfully completed the acceptance tests of the flight engine identified for the first unmanned Gaganyaan (G1) mission tentatively scheduled for second quarter of 2024.
This engine will power the upper stage of the human-rated LVM3 vehicle and has a thrust capability of 19 to 22 tonnes with a specific impulse of 442.5 seconds, it was noted.

RCB calmer than last year, players clear about their roles: Krunal Pandya
Bengaluru (PTI): The atmosphere in the Royal Challengers Bengaluru camp is much calmer than last year and players have a lot more understanding of their roles this season, says Krunal Pandya.
RCB won the Indian Premier League trophy for the first time in 18 years in 2025 and Pandya was the Man-of-the-Match in the final against Punjab Kings at Ahmedabad, returning 4-0-17-2 as RCB won the contest by six runs.
"I feel that this year there is a much calmer atmosphere. Last year it was a new team, and everyone got to know each other. This year many players understand their roles and each other's strengths and weaknesses," Pandya said in a release by the franchise.
"When I get into the big occasions, I feel that if God has got you here, then there is a reason behind it and sometimes I think that these big occasions are actually made for me. I feel the pressure, but I think about how I can be calm and in the present moment and do what is required," he said.
Pandya said RCB icon Virat Kohli would easily rank among the greatest players in any era of cricket.
"Virat is a classic example. You can see that hunger; you can see that passion in how he sees the game and how much he wants that victory. If Virat Kohli had been born in any (some other) generation, he would still be one of the greats. He is not competing with anyone else," he said.
