ISRO repeats history with GSLV Mark III rocket, GSAT-19 satellite launch

Noone in their dreams could ever thought ISRO would launch more than 100 satellites and this time another satellite GSAT has been launched as ISRO's 105 satellite. Probably, this is a gift that ISRO wanted to give to all the fellow Indians. Let's discover more and more on this satellite launch here:

The Indian Space Research Organization (Isro) launched its heaviest rocket— the GSLV MK III—to put the GSAT-19 communications satellite into orbit, in a demonstration of its capability to hurl next-generation satellites into orbit and carry astronauts into outer space.

Launching Time:

At 5.28pm, the 43m, 640-tonne geosynchronous satellite launch vehicle (GSLV) Mark III (D1), lifted off from the Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh.

GSAT-19 Mission:

  • The rocket’s mission was to place the 3,136kg GSAT-19 communications satellite into a geosynchronous transfer orbit (GTO) at 36,000km above earth.
  • The successful first developmental flight opens up commercial opportunities for Isro to launch heavy satellites for foreign customers besides reducing its own dependence on foreign space organizations such as Arianespace SA.
  • The satellite will use multiple spot beams covering all of India. Isro claims this will increase internet speeds and connectivity, depending on the ground infrastructure.
  • It demonstrates Isro’s ability to launch satellites weighing as much as 3.5-4 tonnes, up from 2.2-2.3 tons in the past.

Words from Prime Minister:

“The GSLV-MKIII D1/GSAT-19 mission takes India closer to the next generation launch vehicle and satellite capability. The nation is proud,” Prime Minister Narendra Modi wrote in a Twitter message.

Some Fun Facts about GSAT-19:

  • With the launch, Isro has demonstrated its mastery in developing a cryogenic engine.
  • The launch has also laid a strong foundation for its ambitious future projects, including Chandraayan-II and a manned mission.
  • The launch is also the first flight for CE-20 engine , which was under development since 2002. The engine, which runs on a less complex technology compared to its Russian design predecessors, has undergone more than 200 tests in the last few years.

About ISRO:


The launch is the latest in a string of successes for Isro, which in February launched a record-breaking 104 nano satellites into orbit, all onboard a single rocket. On 5 May, Isro launched the 2,230kg GSAT-9 to boost connectivity among South Asian countries.

In November 2013, India launched a space probe that has been orbiting Mars since September. Last year, in nine missions, it placed 32 satellites in orbit.

What Next?

Satish Dhawan Space Centre director P Kunhikrishnan said, "Isro has made it a habit to execute complex jobs in the most professional way. This has culminated in yet another successful event in Sriharikota."

Kunhikrishnan said integration for the next launch PSLV C38 is going on in the first launch pad simultaneously. "It is planned in the next half of the month. The next GSLV Mk III will be integrated in the new vehicle assembly coming up which will be three times bigger," he said.
