Indian Space Research Organisation (ISRO) successfully launched the country’s heaviest rocket so far – Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III) which put the 3 ton (3136 kg) communications satellite 'GSAT-19' into its intended orbit today at about 5:45 p.m IST.
The success of this launch is crucial on multiple levels:
First, the vehicle is termed 'human rated' because of its several features meeting the criteria to send humans into space and with its success, India's own human space mission is now in sight.
Liquid Propulsion Systems Centre (LPSC) director S.Somnath said that "GSLV-MK III is a possible human-rated launch vehicle by virtue of its design features including its simple module, its technology for lesser propulsion system, lesser accelerator levels, lesser dynamic pressure load and lesser noise or benign acoustic levels" Further, it has more redundancy which means that if an electronic part fails other part will take over the task to propel the vehicle forward, he said.
It may be noted that the term `human-rated' certifies a spacecraft, launch vehicle or airplane as worthy of transporting humans.
Second, total indigenous development and production.
The launch vehicle (GSLV-Mk III) weighing 640 tonnes and standing 43.43 metres tall is designed and developed at Vikram Sarabhai Space Centre (VSSC). Most importantly, the rocket's main and bigger Cryogenic Engine (CE-20) is developed indigenously at ISRO's Liquid Propulsion Systems Centre (LPSC) and tested at ISRO Propulsion Complex (IPRC), while the satellite gyros and navigational system is developed at ISRO Inertial Systems Unit (IISU).
Third, this successful launch took India a huge step closer to self-reliance.
"India need not depend on European Space Agency (ESA) for further heavy launch of INSAT-class satellites of 3.5 ton that incurs a cost of Rs 800 crore each. At one third the cost or at about Rs 350 crore, India can launch heavier satellites on GSLV-Mk III," - GSLV MK III Vehicle director J.Jayaprakash said. Till now, PSLV could launch around 1000 kg satellite, GSLV about 2000 kg and now with this GSLV-Mark III, India can launch heavy satellites of 4000 kg (4 ton) and above," he added.
About the satellite:
The GSAT-19, with a lifespan of 10 years, is a multi-beam satellite that will carry Ka and Ku-band payload along with a Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of the charged particles and influence of space radiation on spacecraft and electronic components.
The satellite also features several advanced technologies including miniaturised heat pipe, fibre optic gyro, Micro Electro-Mechanical Systems (MEMS) accelerometer, Ku-band TTC transponder, as well an indigenous Lithium-ion Battery.
