India successfully tested a new engine for its Geosynchronous Satellite Launch Vehicle (GSLV) April 28.

The Indian Space Research Organisation fired the domestically developed CE-20 engine for 645 seconds on a test stand.

The engine, which uses liquid hydrogen and liquid oxygen propellants, will be used on the upper stage of the Mark 3 version of the GSLV, improving its payload performance. ISRO expects that engine to be ready to fly by the end of 2016.
