India stepped towards Manned Space Mission...
GSLV Mark III, India's Largest Rocket,
The rocket, designed to carry heavier communication and other satellites into higher orbit, blasted off from Satish Dhavan Space Centre at Sriharikota in Andhra Pradesh.
Prime Minister Narendra Modi hailed the test mission on Twitter, as "yet another triumph of (the) brilliance and hard work of our scientists."
"This was a very significant day in the history of (the) Indian space programme," Indian Space Research Organisation (ISRO) chairman KS Radhakrishnan said from mission control as fellow scientists clapped and cheered.
ISRO scientists have been riding high since an Indian spacecraft successfully reached Mars in September on a shoe-string budget, winning Asia's race to the Red Planet and sparking an outpouring of national pride.
Although India has successfully launched lighter satellites in recent years, it has struggled to match the heavier loads sent up by other countries.
The new rocket, weighing 630 tonnes and capable of carrying 4 tonnes, is a boost for India's attempts to grab a greater slice of the $300-billion global space market.
"India, you have a new launch vehicle with you. We have made it again," ISRO mission director S Somnath said.
The rocket - officially named the Geostationary Satellite Launch Vehicle Mk-III - was carrying an unmanned crew capsule which ISRO said successfully separated from the rocket and splashed down in the Bay of Bengal off India's east coast 20 minutes after liftoff.
The Indian-made capsule is designed to carry up to three astronauts into space.
ISRO says the crew capsule project would take at least another seven years to reach the point where an astronaut could be put into space.
