ISRO Successfully Completes Key Engine Test for Gaganyaan-2 Mission
The Indian Space Research Organisation (ISRO) has successfully tested the high-thrust cryogenic engine for the upcoming Gaganyaan-2 mission.
2-Minute Summary (TL;DR)
- ISRO successfully hot-tested the CE-20 cryogenic engine for Gaganyaan-2 on May 5, 2026, for 720 seconds.
- The CE-20 engine powers the upper stage of the LVM-3 launch vehicle for Gaganyaan missions.
- Gaganyaan-2 is the second uncrewed mission, focusing on testing the crew escape system and orbital module.
- The LVM-3 is the heavy-lift rocket developed by ISRO for human spaceflight missions.
- The test was conducted at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu.
- Cryogenic engines use super-cooled liquid hydrogen and liquid oxygen for high efficiency.
- The first crewed Gaganyaan mission (Gaganyaan-3) is tentatively scheduled for 2027.
- Gaganyaan aims to demonstrate India's capability for safe human spaceflight to Low Earth Orbit (LEO).
How This Topic is Tested in Competitive Exams
| Exam | Frequency | Approx. Marks | What Gets Asked |

- ISRO Satellite Centre, Bengaluru
- Vikram Sarabhai Space Centre, Thiruvananthapuram
- UR Rao Satellite Centre, Bengaluru
- ISRO Propulsion Complex, Mahendragiri
Explanation: The crucial hot test of the CE-20 cryogenic engine was successfully carried out at the ISRO Propulsion Complex (IPRC) located in Mahendragiri, Tamil Nadu.
Q4. What is the primary objective of the Gaganyaan-2 mission?
- To send astronauts to the Moon
- To test the crew escape system and orbital module
- To deploy a new communication satellite
- To conduct a long-duration stay in Low Earth Orbit
Explanation: Gaganyaan-2 is designed as the second uncrewed mission to specifically test critical systems for astronaut safety, including the crew escape system and the performance of the orbital module.
Q5. Which launch vehicle is designated to carry the Gaganyaan spacecraft?
- PSLV-XL
- GSLV Mk II
- Launch Vehicle Mark-3 (LVM-3)
- SSLV
Explanation: The Launch Vehicle Mark-3 (LVM-3), also known as the 'Bahubali' rocket, is the heavy-lift launch vehicle chosen by ISRO to carry the Gaganyaan spacecraft, including its crew or test modules, into orbit.
How to Prepare Science & Technology for Government Exams — ISRO Successfully Completes Key Engine Test for G…
For Railway exams, make flashcards for every major ISRO launch — name, payload, purpose, date. These repeat frequently.
For SSC, focus on defence acquisitions and their strategic significance rather than technical specs.
For UPSC, connect every scientific development to policy — climate targets, digital India, health policy.
