The next generation heavy launch vehicle GSLV Mk-III rocket, nicknamed the "Fat Boy", will place the 3,136kg communication satellite GSAT-19 into the orbit on its maiden flight.

The GSLV Mk III rocket lifted off around 5.30 pm local time carrying the GSAT-19 satellite, weighing 3,136 kg, from the Sriharikota space centre in Andhra Pradesh state.

India on Monday scripted history as it successfully launched its heaviest rocket GSLV MkIII-D1 carrying communication satellite GSAT-19. Today on May 5th, researchers will blast off the GSLV-MK III which is carrying the GSAT-19 along with it from the Sriharikota at 5:28 pm. Putting it simple, today's launch success will help India to no longer depend on Europe's Ariane launches for putting its own heavy satellites into the geostationary orbits.

The President Pranab Mukherjee and the Prime Minister Narendra Modi congratulated ISRO for this historic launch. Nicknamed the "Naughty Boy", the successful launch of GSLV Mk III propels India to the big league, with only a couple more countries in the world having similar capabilities. "The payload will be gradually increased in future flights", Vikram Sarabhai Space Centre Director K. Sivan had told IANS.

GSLV-Mk III at around 43 metres is slightly shorter than Mk-II version that is around 49 metres tall.

Until now, ISRO was dependent on foreign launchers for launching communication satellites that weighed more than 2300 kg. The launch adds India's reputation as a reliable low-priced option for space exploration.

The three-stage rocket is powered by two solid strap-on motors at the bottom, a liquid propellant core stage and the cryogenic upper stage.

Vice President of India M. Hamid Ansari while congratulating ISRO said that the successful launch of the indigenously developed heavy lift space vehicle, including the cryogenic stage, demonstrates India's ability to launch large payloads. The newly launched rocket is expected to be able to take Indian astronauts into space. Heavy rocket and heavy satellite is a cost effective combination in the space field.

Indian space scientists worked "relentlessly for decades and for this project since 2002 to successfully put the satellite into orbit", Kumar said.
