Indian Space Research Organisation (ISRO) has received approval from the Space Commission to develop a semi-cryogenic engine which will increase the lifting capabilities of the GSLV Mk 3 rocket by one tonne. Once the semi-cryogenic engine is fitted in the rocket, the GSLV Mk 3 will be able to carry 5 tonnes from the earlier 4 tonnes. The deadline for developing the engine has been set at 29 months, K Sivan, ISRO Chairman said.
Following a presentation by the ISRO to the Space Commission, India’s space agency received approval for developing the semi-cryogenic rocket stage, ISRO Chairman told The Times of India. He further explained the stages of the rocket- two strap-on boosters for thrust during launch, a middle stage that carries liquid fuel, and the second stage which has the cryogenic engine. The semi-cryogenic engine, once developed, will replace the middle stage, and is designed to be a perfect fit, he added.
With improved load carrying capabilities, ISRO hopes to rely less on foreign spaceports to launch Indian satellites weighing over 5 tonnes. With the upcoming Gsat-29 satellite launch scheduled for July, Sivan said that the satellite will track the production of 25 crops from the earlier eight. India’s space agency has over 12 remote-sensing sensing satellites, some of them being Resourcesat, Cartosat and Risat-1 for agriculture forecast.
With increased demand, ISRO plans to launch six more satellites aimed at cartography, oceanography and environment, land and water, the report added.
