Successful completion of Human rating of CE20 Cryogenic engine for the Gaganyaan Programme​


February 21, 2024


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 missions, with the completion of the final round of ground qualification tests on February 13, 2024. The 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 the flight conditions.


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 w.r.t thrust, mixture ratio, and propellant tank pressure. All the ground qualification tests of the CE20 engine for the Gaganyaan programme have been successfully completed.


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 8810 seconds against the minimum human rating qualification standard requirement of 6350 seconds.


ISRO has also successfully completed the acceptance tests of the flight engine identified for the first unmanned Gaganyaan (G1) mission tentatively scheduled for Q2 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.

How ISRO’s PSLV Integration Facility launch at Sriharikota will help India’s space ecosystem

Bengaluru: In an effort to increase the number of PSLV rocket launches and launches of other small vehicles, the Indian Space Research Organisation (ISRO) has built and formally launched a PSLV Integration Facility (PIF) in Andhra Pradesh’s Sriharikota. The new facility, inaugurated by Prime Minister Narendra Modi Tuesday, will enable quicker assembly and integration of the PSLV (Polar Satellite Launch Vehicle) and smaller rockets at the launchpad. The complex is an augmentation of the First Launch Pad (FLP) at the Satish Dhawan Space Centre in Sriharikota.

The move is expected to increase PSLV launches annually, from about six to over double the number, at 12 or 15. Launches of customer satellites through India’s trustiest rocket PSLV are ISRO’s primary source of revenue. The PIF is also expected to help launch smaller rockets and private launch vehicles in the future.

Full interview is out now @Gessler et al.

Isro Chairman S Somanath, in an exclusive interview to TOI’s Chethan Kumar on March 12, spoke about multiple Space projects India is currently implementing and gave a sneak peek into what may lie ahead. From when the selection of the second batch of astronauts could begin to what stage the proposal for Chandrayaan-4 is and from need to correct alignment of payloads on India’s Sun mission (Aditya-L1) to how many astronauts could go as part of the first Gaganyaan mission, he spoke at length on a variety of issues. He also addressed the issue of manpower and spoke about the New Generation Launch Vehicle (NGLV) which is critical for building India’s space station and eventually sending humans to Moon. Watch full interview more details.

Launch coming up:

A rocket named Agnibaan is ready for lift off from a specially made private launch pad named Dhanush' created inside India's mega ISRO owned rocket port at Sriharikota. This will be the first sub orbital test flight of this launch vehicle made by the start up. NDTV's Science Editor Pallava Bagla, caught up with Mr Moin SPM the co-founder of Agnikul Cosmos Private Limited at the high tech rocket factory.

Second RLV landing experiment, LEX-02, this time approaching the landing zone from off-nominal conditions & demonstrating autonomous maneuvering has been completed successfully. The vehicle 'Pushpak' has touched down from an altitude of about ~15,000 ft:

Currently, we're using an IAF Chinook to take it to altitude before being dropped...

...but the next phase of testing (where we'd move to the full-scale RLV with its own propulsion) should see us using this:
