India’s space network agency, Indian Space Research Organisation (ISRO), has unveiled its heaviest rocket, capable of carrying satellites weighing 10 tonnes into space.

The rocket will be powered by semi-cryogenic engine being built by Godrej Aerospace, a private firm engaged in hi-tech aerospace manufacturing activities.

The proposed new rocket would be powered by a semi-cryogenic engine that runs on kerosene and liquid oxygen, which the space agency is currently developing. S. Somanath, Project Director of Geosynchronous Satellite Launch Vehicle (GSLV) Mark III, said that ISRO currently uses a CE-20 engine to power the upper stage of GSLV.

The CE-20 engine is a cryogenic rocket engine being developed by the Liquid Propulsion Systems Centre, a subsidiary of ISRO. Using the semi-cryogenic engine in such a combination, the payload of the rocket will increase to 10 tonnes.

The space agency has not set a deadline by when the rocket will be ready for use, but it is estimated that a fully-fledged rocket with a communication satellite will be launched in 2017.
