The Indian Space Research Organisation (ISRO) has successfully conducted a key ground test of its CE20 cryogenic engine, marking progress in improving the performance of India’s heavy-lift rocket, the LVM3 launch vehicle.
The sea-level hot test was carried out on March 10, 2026, at the ISRO Propulsion Complex, where the engine ran for 165 seconds and generated approximately 22 tonnes of thrust. The CE20 engine powers the upper stage of LVM3 and plays a crucial role in launching heavy payloads into space.
ISRO said the higher-thrust capability demonstrated during the test could significantly enhance the rocket’s payload capacity for future satellite launches and deep-space missions. The engine has also been human-rated for the country’s ambitious Gaganyaan programme, India’s first crewed spaceflight mission.
Officials said the successful test strengthens India’s technological readiness for upcoming missions and underlines the country’s growing capabilities in advanced rocket propulsion systems.
