India will test-fly its heaviest and upgraded rocket – the Geosynchronous Satellite Launch Vehicle (GSLV-Mark III) – on December 18, space agency Isro said Friday.

According to a tweet by the Indian Space Research Organisation (Isro), the 630-tonne rocket will be powered by liquid and solid fuel engines while the cryogenic stage/engine will be a passive one.

The rocket will also carry a crew module to test its re-entry characteristics.

“The main purpose of the mission is to test the atmospheric characteristics and stability of the rocket on its way up. We also decided to use this opportunity to test one component of the crew module – a human space mission that India may embark on at a later date,” M.Y.S Prasad, director of the Satish Dhawan Space Centre in Sriharikota, told reporters in a recent interaction.

The experimental mission will cost Rs. 155 crores and will not carry any satellite as the cryogenic engine needed for the purpose is still under development, he said.

“This will be India’s new launch vehicle. It is bigger and can carry satellites up to four tonnes,” said GSLV Mark III project director S. Somanath.

The main objective of the crew module is to demonstrate its re-entry flight and aero braking, and end-to-end parachute system validation.

The rocket will go up to 126km and the crew capsule will then detach and fall into the Bay of Bengal, 20 minutes after blast-off.

The descent speed of the crew module will be controlled on board motors for some distance and then by three parachutes.

The module will splash down 600km from Port Blair and 1,600km from the space centre. The capsule will be recovered by an Indian Coast Guard or Indian Navy ship.

  1. I guess, they wanted to say “heaviest rocket for India”. Because the heaviest and the first environmentalist rocket of the world of Russia “Ангара-А5” (Angara-A5) is first time used in last week. Angara, began to be used instead of the “Proton”, which was the legendary Russian rocket of the Cold War era. Environmentalist, because, it uses the kerosene as the starting fuel. Yes, known kerosene:) In its thrust mass is 980 tons at the ground level. Even, 16 hours were spent for placing to the rocket launcher of it’s in June, 2014 in Baikonur. Its launch mass is 790 tons. Of course, 80% of the mass is liquid fuel. And until the return to orbit of the earth, most of it is spent. Then, it’s landing down with the remaining fuel. Rockets don’t seem like the birds but, they lost a lot of mass, can be said:) After reading this article about India, I wondered to that: When will the humanity discover the lighter elements with envisaged different molecular levels and will be used to for the rockets, about in 2300 year (according to sci-fi)? Thanks for your news. I went and came back in the period of between the Star Wars and the Cold War with this news:)
