Current Context: ISRO has successfully test fired the CE-20 cryogenic engine of its moon mission rocket on February 24 at its Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu³. The engine will be used for the third stage of India's Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III) that will launch Chandrayaan-3.
- A cryogenic engine is a type of rocket engine that uses very low-temperature liquid propellants such as liquid hydrogen and liquid oxygen. These propellants are stored at extremely low temperatures and are pumped into a combustion chamber where they ignite and produce thrust.
- A cryogenic engine works on the principle of reaction thrust, which means that it throws mass in one direction and relies on the opposite force in the other direction.
- According to The Week, ISRO has successfully conducted the key test on cryogenic engine for Chandrayaan-3 mission on February 28 at its Liquid Propulsion Systems Centre (LPSC) at Valiamala near Thiruvananthapuram. The test was carried out for a planned duration of 25 seconds and demonstrated all performance parameters
- It is more environmentally-friendly than other options because it produces less greenhouse gases and pollution.
- It is non-toxic and non-corrosive, which makes it safer to handle and store.
- It has a higher mass flow rate than fossil fuels, which means it produces more thrust and power with less fuel consumption.
- It has a high-specific impulse, which means it can achieve higher speeds and altitudes with less propellant mass.
