India successfully launched its communication satellite GSAT-6, which has several strategic applications, in textbook style on Thursday using its heavy rocket geosynchronous satellite launch vehicle (GSLV-D6). The GSLV rocket, with a desi cryogenic engine, slung the satellite in a geosynchronous transfer orbit (GTO) from where it would be taken up to its final geostationary orbit.

Communication satellite put in orbit successfully
Sriharikota: India successfully launched its communication satellite GSAT-6, which has several strategic applications, in textbook style on Thursday using its heavy rocket geosynchronous satellite launch vehicle (GSLV-D6). The GSLV rocket, with a desi cryogenic engine, slung the satellite in a geosynchronous transfer orbit (GTO) from where it would be taken up to its final geostationary orbit.
The successful flight of GSLV rocket gives the Indian space programme a much-needed booster as getting the more-efficient cryogenic engine (which provides more thrust for every kilogram of propellant burnt) right is important for its future space programmes.
Indian space scientists have spent around two decades in conceiving the cryogenic technology and spent around Rs 400 crore in developing it. Precisely at 4.52 pm, the Geosynchronous Satellite Launch Vehicle-Development 5 (GSLV D6) rose from the second launch pad here at the Satish Dhawan Space Centre.
The 49.1-metre tall rocket weighing 416 tonnes slung the 2,117 kg GSAT-6 communication satellite in the geosynchronous transfer orbit (GTO) around 17 minutes into the flight. As the whole mission concluded successfully, ISRO scientists at the mission control centre were visibly happy, back-slapping and hugging each other once the rocket ejected the GSAT-6 satellite into the intended orbit.
Speaking about the launch, ISRO chairman A S Kiran Kumar said: "Today's performance of launch vehicle was normal. The intricacies of cryogenic engine have been understood." This is the first successful GSLV rocket launch that placed a satellite in orbit in Kiran Kumar's tenure.
The Indian space agency flew the GSLV rocket with its own cryogenic engine for the second time on Thursday after the successful launch of a similar rocket in January 2014 that put into orbit GSAT-14. This was the second mission of GSLV during the last five years after two such rockets failed in 2010.
