Isro successfully tests cryogenic engine of its rocket for the moon mission
According to the Indian Space Research Organisation, the flight acceptance hot test for the CE-20 cryogenic engine, which will power the country`s rocket for its third moon mission, Chandrayaan-3, was successfully completed (ISRO).
Key Points
- The LVM3-M4 rocket’s cryogenic upper stage will be powered by the CE-20 cryogenic engine, according to the space agency.
- On February 24, a 25-second hot test was performed at the ISRO Propulsion Complex in Mahendragiri, Tamil Nadu.

What is a Cryogenic engine?
- Cryogenic Engine: The Greek words “Kyros” (cold or freezing) and “gene” are the origin of the word “cryogenic” (burn or produced).
- A cryogenic engine is a rocket engine that runs on a cryogenic fuel and oxidizer, both of which are liquefied gases that are maintained at very low temperatures.
- Cryogenic technology is the use of rocket propellants at extremely low temperatures. Cryogenic rockets are theoretically a considerably more complicated technology than solid or liquid propellant (stored on earth) stages because they utilise propellants at extremely low temperatures.
- Yet, compared to other types of propellants, such as solid and liquid propellant rocket engines, a cryogenic engine is more efficient and generates more force per kilogramme of cryogenic propellant consumed.
