The Indian Space Research Organisation (ISRO) on Thursday said that the CE20 cryogenic engine flew through in a critical sea level test, a significant breakthrough in propulsion technology and future of the country's space missions.

The Indian Space Research Organisation (ISRO) on Thursday announced that itsC20cryogenicengine, which had qualified forGaganyaanmission, has successfully aced a crucialtest.

The C20 cryogenic engine, designed for future space missions, has successfully passed a critical test under ambient conditions.

ISRO achieved a breakthrough with the CE20 cryogenic engine passing a critical sea-level test, essential for future missions like Gaganyaan. The upgraded engine can produce a thrust of up to 22 tonnes,

The indigenous CE20 cryogenic engine developed by the Liquid Propulsion Systems Centre is powering the upper stage of the Launch Vehicle Mark-3 (LVM-3) and has been qualified to operate at a thrust level of 19 tonne,

The test, conducted on November 29, 2024, at the ISRO Propulsion Complex in Mahendragiri, Tamil Nadu, demonstrated the engine’s restart-enabling systems under ambient conditions.

CE20 cryogenic engine test used a special ignition system with multiple elements and included a water injection system in the engine's nozzle to help maintain smooth airflow.

The Indian Space Research Organisation (Isro) announces a significant breakthrough as it successfully conducted a sea-level hot test of its CE20 Cryogenic Engine. This test showcases Isro's advanced rocket propulsion capabilities and sets the stage for future space missions.

India's space agency, ISRO, achieved a milestone. The C20 cryogenic engine passed a major test. The test involved restarting the engine in ambient conditions. This success is vital for upcoming missions like Gaganyaan.

ISRO has achieved a key milestone for the Gaganyaan Mission by successfully testing the CE20 cryogenic engine at sea level on November 29, 2024, at its Mahendragiri facility.
