What is CE-20 cryogenic engine?

About CE-20 cryogenic engine:

• It has been designed and developed by the Liquid Propulsion Systems Centre (LPSC) , a subsidiary of ISRO.
• It will power the Cryogenic Upper Stage of the LVM3 launch vehicle for the Chandrayaan-3 mission.
• It is the first Indian cryogenic engine to feature a gas-generator cycle.
• It is one of the most powerful upper-stage cryogenic engines in the world.
• This engine develops a nominal thrust of 186.36 kN in vacuum.

What is a Cryogenic stage?

• The cryogenic stage is technically a very complex system due to its use of propellants at extremely low temperatures and the associated thermal and structural problems.
• It uses liquid fuels that are cooled to very low temperatures.
• A Cryogenic rocket stage is more efficient and provides more thrust for every kilogram of propellant it burns compared to solid and earth-storable liquid propellant rocket stages.

Chandrayaan-3 Mission:

• Chandrayaan-3 is India’s third moon mission and is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface.
• Chandrayaan-3 mission has three major modules — the Propulsion module, Lander module, and Rover.
• The mission is slated to be launched later this year by Launch Vehicle Mark 3 (LMV3) from the Satish Dhawan Space Centre at Sriharikota.
