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.

Aiming to start a manned space mission, the ISRO will launch the GSLV Mk-III in the second week of December to study its performance and carry out a crew module recovery experiment through it.

The 630-tonne launch vehicle, designated as LVM3-X, will carry CARE (Crew Module Atmospheric Reentry Experiment) weighing about 3.65 tonnes. The Isro intends to study the impact of heat on the crew module when it enters the earth atmosphere.

Briefing the media on the salient features of the experimental mission, Satish Dhawan Space Centre director, Dr M.Y.S. Prasad said that the objectives of the mission are flight validation of the complex atmospheric flight regime of LVM3 vehicle, validation of new design features and overall integrity of the mission design.

The experimental flight will provide all the inputs required for the first developmental flight of the GSLV Mark-III, which is being planned within next two years. It will carry a communication satellite of four tonne nominal payload capability.

Dr Prasad said that Care is expected to enhance their understanding on re-entry and parachute phase of crew module. The crew module, after getting separated from the launch vehicle at an altitude of 125 km, will re-enters Earth’s atmospheric at about 80 km and descend in ballistic mode.
