ISRO successfully launches GSLV-D6 carrying GSAT-6 satellite

The Indian Space Research Organisation (ISRO) has successfully launched India’s communication satellite GSAT-6 using its heavy rocket Geosynchronous Satellite Launch Vehicle (GSLV-D6) from Satish Dhawan Space Centre in Sriharikota. This is the second consecutive success with indigenous cryogenic engine capable of carrying 2-2.5 tonne class of spacecraft. The rocket carrying the cuboid shaped GSAT-6 communication satellite weighing 2,117 kg slung it in GTO around 17 minutes into the flight.

ISRO scientists had spent nearly two decades in conceiving and mastering the cryogenic technology. Around Rs 400 crore was spent on developing the technology. A cryogenic engine is more efficient as it provides more thrust for every kilogram of propellant burnt.

The next GSLV launch will be in June or July next year. ISRO has set a target of two GSLV launches every year. Currently, India’s heavy communication satellites are launched by an European space agency Ariane and the success of GSLV would help the country to save huge foreign exchange.

Points to Note
  • GSLV-D6 is the ninth flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV). It is also the fifth developmental flight of GSLV.
  • This is the second time Isro flew the GSLV rocket with its own cryogenic engine, after the successful launch of similar rocket in January 2014 that put into orbit GSAT-14.
  • GSAT-6 is India’s 25th geostationary communication satellite and twelfth in the GSAT series.
  • The GSLV D-6 launch gives a big boost to ISRO to invest more on its heavier rocket GSLV-Mk-III, that can eventually take a man to space.
  • It is a success after two decades of struggle over technology denial regimes.

What is the major difference between PSLV and GSLV?

Click to View Answer

PSLV is a launch vehicle primarily used for launching satellites in the low earth orbit or the polar orbit.

GSLV is primarily for launching satellites to the geosynchronous transfer orbit or GTO (communication satellites) and can inject a 2 ton satellite into orbit.
