ISRO successfully launches India's heaviest GSLV Mark III with GSAT-19 satellite

India has long worked towards developing its own cryogenic engine, the upper stage engine technology required to carry heavier communication satellites, as showcased in Monday's launch.

It took Isro 15 years to build "100% desi rocket", as scientists often call GSLV Mk III.

The 43.43 metre tall rocket lifted off at 5.28 pm from the second launch pad at the Satish Dhawan Space Centre and launched the 3,136 kg GSAT-19, the heaviest satellite to be launched from the country.

Prime Minister Narendra Modi congratulated ISRO for the feat, and said the GSLV Mark-III/GSAT-19 mission takes India closer to the next-generation launch vehicle and satellite capability.

Indian space scientists have finally tamed their "Naughty Boy", by successfully demonstrating the capability of the GSLV MkIII launch vehicle in its maiden attempt. The nation is proud.

At 3,136 kgs the GSAT-19 satellite will be the heaviest India has attempted to put in orbit, the space agency said. "The satellite is being termed as 'a game changer communications satellite for India" as it would alone do the work of 6-7 of the older variety of communication satellites in space.

The rocket is powered by an indigenous engine that uses liquid oxygen and liquid hydrogen as propellants, Kumar told reporters. Since then, space experts and fans are inquisitive about major developments in ISRO. In 2014, ISRO had successfully tested the Crew module Atmospheric Reentry experiment with the flight GSLV MkIII. It has been coupled with several other payloads, including a Geostationary Radiation Spectrometer (GRASP) to analyze the nature of charged particles and the influence of space radiation of electronic components.

Before this India had depended on foreign communicated rockets for launch. Monday's launch carried the almost 7,000-pound GSAT-19 satellite, which has a 10-year life cycle and is meant to improve telecommunications and Internet services.

The three-stage vehicle GSLV-MK III D1 contains the two solid motor strap-ons.

The rocket used a cryogenic engine, developed in India after the United States leaned on Russian Federation in the 1990s not to supply such a powerful engine in case it was used for missiles. Former ISRO chairman K Kasturirangan, the man who created the GSLV Mk III, confirms that this will be India's vehicle to ferry Indians into space.
