 "GSLV Mark-III lifts off successfully from Sriharikota")
The Indian Space Research Organisation (Isro) successfully tested its Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mark III) on Thursday, carrying a crew module, to be used in manned space missions. The launch has proved Isro can put an astronaut into space and bring him or her home.
The year gone by saw some big events in Indian space research. These included entering into Mars' orbit at the first attempt and a GSLV rocket powered by its own cryogenic engine early this year.
"The performance of solid and liquid propulsion stages happened as expected. The crew module has plunged into the sea. The next developmental flight of the launch vehicle will be done in two years," said Chairman K Radhakrishnan on Thursday.
At 9.30 am on Thursday, the 630-tonne and 43.43 metre Mark III lifted from the second launch pad of the Satish Dhawan Space Centre at Sriharikota, near Chennai. This is the the heaviest launch vehicle Isro has made.

Minutes later, Prime Minister Narendra Modi tweeted, "Successful launch of GSLV Mk-III is yet another triumph of the brilliance and the hard work of our scientists. Congratulations to them for the efforts.”
The Rs 155-crore mission has two purposes. The main purpose is to test the rocket’s atmospheric flight stability with four-tonne luggage. The second is to study re-entry characteristics of the crew module, its aero braking and validation of its end-to-end parachute system. The capsule was the size of a small bedroom and could accommodate two to three.
According to Isro, the crew module separated from the rocket at an altitude of 126 kilometres (km) and re-entered the earth's atmosphere at 80 km. At an altitude of 15 km, the module’s apex cover separated and parachutes were deployed. These parachutes were designed and made by the Defence Research Development Organisation's laboratory at Agra. The crew module weighed 3.73 tonnes. It separated from the rocket about five minutes after the lift-off from the launch pad.
After the parachutes opened on re-entry, the module landed in the Andaman Sea, about 1,600 km from Sriharikota. The vehicle has now moved a step closer to its first development flight with a functional C25 cryogenic upper stage engine.
A naval ship tracking the signals from the module would pick up the module and it will be delivered at Ennore Port, near this city. From there it will be brought to Sriharikota and then taken to the Vikram Sarabhai Space Centre at Thiruvanthapuram in Kerala.
The Mark III was the second GSLV rocket mission during the past four years. Two such rockets failed in 2010 and this was designed to be a three-stage one, with a lift-off weight of 630 tonnes.
Isro's being able to perfect the cryogenic engine technology would enable foreign exchange to be saved by launching communication satellites itself, beside taking larger orders from others.
