In yet another historic moment for India, the Indian Space Research Organisation (ISRO), which has been touching the skies with back to back feats, on Monday successfully launched the 3,136 kg communication satellite GSAT-19 aboard its heaviest rocket GSLV Mk-III D1 aka 'Fat Boy'.

Meanwhile, Prime Minister Narendra Modi and President Pranab Mukherjee took it to Twitter to congratulate ISRO scientists on their big feat.

The launch of ISRO's GSLV Mk-III took place from second launch pad at the Satish Dhawan Space Centre, Sriharikota at 5:20 PM. The Indian space agency said earlier on Monday that the countdown process for its GSLV Mk-III launch was “progressing normally”. 

ISRO kick-started the 25-and-half hour countdown for the launch on Sunday at 3:58 PM. The scientists were involved in propellant filling operations of the heaviest GSLV-MkIII D1, officials said.

Here are the Highlights:

Why the launch is crucial for ISRO?

With this launch, ISRO will no longer have to depend on foreign launchers to blast off communications satellites that weigh more than 2,300 kg. The GSLV Mk-III D1 can carry payloads of up to 4,000 kg into the Geosynchronous Transfer Orbit (GTO) and 10,000 kg into the Low Earth Orbit.

Described as a ‘game-changer’ in the first of its kind space mission, the GSLV Mark-III rocket can manage to carry a heavier 4-tonne communications satellite.

With the launch of the GSLV Mark-III rocket, the Indian space agency is eying a greater share of the multi-billion dollar global space market with an aim to lessen dependency on foreign launching vehicles.

Currently, the Indian space agency is capable of launching payloads of up to 2.2 tonnes into the intended orbit. For anything above the aforementioned weight, ISRO had to seek help of foreign launch facilities.

About the GSLV Mk-III D1:

The GSLV Mk-III D1 is a three-stage vehicle with indigenous cryogenic upper stage engine designed to carry heavier communication satellites into the GTO.

The heaviest rocket will push satellites into geostationary orbit and will be used as a launcher for an Indian crew vehicle. The GSLV Mark-III is equipped with an Indian cryogenic third stage and has a higher payload capacity compared to the current GSLV.

GSLV Mark-III will lift Ka and Ku-band payload as well as a Geostationary Radiation Spectrometer (GRASP) payload. The purpose is to study and monitor the nature of the charged particles and influence of space radiation on spacecraft and electronic components.

The GSLV Mark-III rocket will also feature advanced spacecraft technologies including bus subsystem experiments in electrical propulsion system, indigenous Li-ion battery and indigenous bus bars for power distribution, among others.

What ISRO Chairman AS Kiran Kumar says?

The mission is important as “it was the heaviest-ever rocket and satellite to be launched from the country,” ISRO Chairman A S Kiran Kumar had said.

“GSLV Mark-III is our next launch. We are getting ready.  All the systems are in Sriharikota. The integration is currently going on,” Kumar had said last month.

“The whole process of assembling the various stages and then integrating the satellite into the heat shield, these activities are going on. First week of June is when we are targeting this launch,” he said.

Kiran Kumar said that since ISRO had to launch from foreign soil the communications satellites built beyond the capacity of 2.2 tonnes, efforts are now on to launch satellite up to 4 tonnes and even beyond in India itself.

He said in terms of cost-effectiveness, the ISRO-developed technology on lithium ion batteries is good for space programme, but it requires the efforts of industry to develop it to reduce costs.
