ISRO’s biggest in 30 years: Powerful GSLV-MkIII launches heaviest satellite GSAT-19

The Indian Space Research Organisation (ISRO) successfully launched its most powerful indigenous rocket, GSLV Mk III, carrying a 3,136-kg GSAT- 19 communication satellite, from the Satish Dhawan Space Centre in Sriharikota, in Andhra Pradesh, on Monday evening. The 43.43 metre-tall GSLV Mk III is a new, improved and powerful version of the GSLV rockets developed by ISRO, and features an indigenously developed cryogenic engine which provides a huge final thrust to the rocket after the initial solid and liquid fuel engine stages.

“GSLV Mk III D1 successfully launches GSAT 19,’’ ISRO tweeted shortly after the launch. “Cryogenic stage performance is normal,’’ it said, after reporting normal performance in the liquid L110 engine stage and the S200 solid propellant stage. ISRO chairman A S Kiran Kumar described the launch as a step towards “self reliance’’ for India in the launching of heavy satellites.

The C25 engine was developed indigenously by ISRO based on Russian cryogenic engines which the agency used during early phases of the development of the GSLV rockets. “Mastering this complex, high-performance cryogenic propulsion technology will go a long way in building self reliance for the Indian space programme,’’ ISRO has said with reference to the GSLV programme. The L110 liquid fuel engines — an improved version of the ISRO’s Vikas solid fuel engines — used in the second stage of the GSLV Mk III rocket are one of the heaviest earth storable liquid stages ever developed by ISRO.
