& ISRO (@isro) June 4, 2017

Isro's upcoming endeavours - the GSAT-19 and the GSAT-11 satellites - are potential game changers and can revolutionise communications by empowering a digital India and providing internet services and streaming like never before.

ISRO began work to build indigenous cryogenic engine in the 1970s, though it gained momentum after Russia denied transfer of technology . But it was delayed as the space agency had to focus on their immediate requirements including development of Vikas engine, which now powers both PSLV and GSLV .
