What was successfully tested at ISRO’s engine facilities in February 2025?
Show answer & explanation
Correct answer: B
Explanation
Correct Answer:
CE20 engine ignition in vacuum
Explanation:
In February 2025, the Indian Space Research Organisation (ISRO) successfully conducted an ignition trial of the indigenous CE20 cryogenic engine (which powers the upper stage of LVM3) using a multi-element igniter under vacuum conditions at the High Altitude Test Facility in Mahendragiri, Tamil Nadu. This critical test simulated the engine ignition environment of space to study restart operations and enhance multi-restart capabilities for future missions like Gaganyaan.
Key Points:
The test was carried out on February 7, 2025, at the ISRO Propulsion Complex (IPRC) in Mahendragiri.
It specifically evaluated the thrust chamber ignition using a multi-element igniter under simulated space vacuum and tank pressure conditions.
The CE20 engine is the powerhouse for the C25 upper stage of India's heavy-lift launch vehicle, LVM3.
