With improved lifting capacity, it can go after more worldwide customers for satellite launches, and try to carve a bigger slice of the $300 billion global space industry.

The only difference, when the GSLV Mk III takes off at 17:28 pm, it will place the Indian Space Research Organisation amongst a select few agencies which can launch satellites of up to 4,000 kg into geostationary orbit.

With the launch of GSLV Mark III, India today enters the elite club of the United States, Russia, Europe, China and Japan in launching heavy satellites.

"Congratulations to the dedicated scientists of ISRO for the successful launch of GSLV - MKIII D1/GSAT-19 mission", PM Modi tweeted.

The GSAT-19's successful launch today will now pave the way for the launch of GSAT-11-a heavier communication satellite-into the space in the near future.

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. 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.

Once the 640 ton new rocket achieves its mission objectives, it would take India forward as an advanced spacefaring nation moving towards self sufficiency in space technology and application.

The GSAT-19, which has a lifespan of 10 years, will help monitor and study the nature of charged particles and influence of space radiation on spacecraft and electronic components, Hindustan Times reported. GSLV-Mk III, when its graduates from its development flight status to operational status, may look at flying heavier foreign satellites. The rocket is powered by an indigenous engine that uses liquid oxygen and liquid hydrogen as fuel, he said.

The mission would also augment India's communication resources as a single GSAT-19 satellite will be equivalent to having a constellation of six to seven of the older variety of communication satellites in space.

With the launch, ISRO has demonstrated its mastery in developing a cryogenic engine, a technology denied to it years ago.

He said the next communication satellite GSAT 18, weighing around 3.2 ton, would be launched using GSLV-Mk II variant while GSAT-11 weighing around 5.8 ton will be launched using Arianespace rocket.

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 rocket is a three stage vehicle with two solid strap motors namely - a S200 a core liquid booster L110 and a cryogenic upper stage C25.
