The GSLV-Mark III, or the Geosynchronous Satellite Launch Vehicle-Mark III, took off from the Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh.

The GSLV-Mark III carried a 3,136-kg GSAT-19 communication satellite--the heaviest to be lifted by an Indian rocket till date--to an altitude of around 179 km above the Earth after just over 16 minutes into the flight.

The GSLV-Mark III rocket is a three-stage vehicle with two solid motor strap-ons, a liquid propellant core stage and a cryogenic engine (C25).
The GSAT-19 is billed as the real game-changer as according to experts it can be the first to provide "Internet services using a space-based platform".
The GSAT-19 will not have transponders, and instead it will beam data using multiple frequency beams. According to experts, this feature will also let the satellite beam more data to the ISRO.
"It is a historic day... Both the GSLV Mk-III and the GSAT-19 launch have been successful... We are looking forward to its (GSAT-19) operations," ISRO chairman A S Kiran Kumar said.
President Mukherjee congratulated ISRO for its historic Launch

Why This Mission is so Important for India ?
After this mission India can now launch four-tonne satellites on its own rocket instead of paying huge amounts of money to foreign space agencies to execute the operation.
We Congratulate & Salute ISRO for such a historic achievement & finally want to say that:
