ISRO GSAT-19 satellite launch on GSLV MkIII: India is inching closer towards the launch of the communication satellite GSAT-19 using Indian Space Research Organisations’s heaviest and upgraded Geosynchronous Satellite Launch Vehicle-Mark III (GSLV MkIII) rocket. The launch vehicle is capable of carrying very heavy payloads and, after six successful attempts, is said to be rated to carry humans into orbit too. With the launch of GSAT-19, ISRO is all set to bring about a phenomenal changes that can revolutionise the communications mechanism in the country.
As per ISRO, the geosynchronous satellite launch vehicle is scheduled to take off on Monday at 5.28 pm. GSLV MkIII is the next generation rocket and former ISRO chairman K Kasturirangan, the man behind the inception of GSLV MkIII has confirmed that it will probably be India’s first vehicle to ferry people into space. With so much riding on India’s heaviest rocket engine’s success, here are 5 super-amazing facts about it:
i) The 640-tonne GSLV MkIII which is equal to the weight of five fully-loaded Boeing Jumbo Jets or 200 fully-grown Asian elephants, is India’s heaviest but shortest rocket with a height of 43 metres. GSLV-Mk III is has the capability of launching satellites weighing up to four tonnes in the Geosynchronous Transfer Orbit (GTO).
ii) The rocket’s first developmental flight, GSLV MkIII-D1, will carry the GSAT-19 satellite. This is India’s first fully functional rocket to be tested with a cryogenic engine that uses liquid propellants — liquid oxygen and liquid hydrogen. The satellite is aimed at improving telecommunication and broadcasting areas of the country.
iii) After immense effort of 25 years, 11 flights and over 200 tests on different components of the rocket, it is all set to carry the GSAT-19 satellite into the space today. GSLV MkIII is a three-stage launch vehicle with two solid motor strap-ons, a liquid propellant core stage (L110) and a cryogenic stage (C-25).

iv) ISRO in Janurary 2014, successfully conducted the static test of GSLV Mark-III at SDSC in Sriharikota. The successful test of S200, which forms the strap-on stage for the GSLV, made it world’s third largest solid booster. The static test of liquid core stage (L110) of GSLV-Mk III launch vehicle was conducted at ISRO’s Liquid Propulsion Systems Centre test facility in March 2010.
v) If it successfully clears tests – the GSLV MkIII was earlier known as Launch Vehicle Mark-III or LMV Mark III – could be India’s first vehicle to ferry people into space.
