With GSLV-D6, ISRO can compete in global two-tonne satellite launch market

Here's why India should celebrate ISRO's launch of GSLV-D6

* The indigenous cryogenic upper stage is successful for the second time in succession, which demonstrates the consistency of the home grown technology.

* Now, India has proven capability to launch two tonne communication satellites  36,000 kms into its home slot-  the geosynchronous transfer orbit

* It is a success after two decades of struggle over technology denial regimes

* From the next mission, ISRO can launch GSLV-Mk-II with satellites for commercial purposes, not just experimental satellites to test new technologies

* ISRO will gain confidence to launch more GSLV rockets and hurl communication satellites, crucial to fill gaps in India’s communication needs

* India’s PSLV rocket is a workhorse that is the most competitive globally for launching satellites on lower earth orbit

* GSLV can now begin to compete globally for two tonne communication satellite launches

* 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
