- It is a high thrust Cryogenic Engine
- It is being developed for GSLV Mark-3
- The GSLV Mark 3, the biggest rocket made in India, will be capable of launching 4-tonne satellites into geosynchronous orbit.
- So far India’s GSLVs were being powered by cryogenic engines given by Russia.
- Cryogenic engines are used in the upper stage of a rocket launch as they provide the maximum thrust to a launcher vehicle
- C25 is another cryogenic engine being tested for GSLV Mark-3
- What are Cryogenic Engines?
- It uses Hydrogen as fuel, stored at minus 253 degrees Celsius and liquid oxygen as oxidizer at minus 193 degrees Celsius.
- Managing combustible fuel at such low temperature makes this challenging
- To store these cryogenic fluids, special multi-layer insulation is provided for the tanks and other structures.
- It is essential to master this technology for any space power as launching heavier satellites requires cryogenic engines even in the lower stages of the rocket.
