Following the successful launch of the Geosynchronous Satellite Launch Vehicle Mk-III (GSLV Mk-III), the Indian Space Research Organisation (ISRO) is slated to launch a kerosene-based semi-cryogenic engine, projected to be functional for flight tests by 2021.
The envisioned engine uses refined kerosene as a propellant, as opposed to the conventional combination of liquid hydrogen and liquid oxygen. However, liquid oxygen will still function as the oxidizer.
An eco-friendly alternative, kerosene can be used after storing at a normal temperature, while the previous liquid hydrogen had to be stored at (-)253 degree Celsius.
Earlier on June 5, India launched the GSLV Mark III carrying the 3,136kg GSAT-19 communication satellite from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
