A step closer to sending astronauts into space

In just 45 days from now, Indian Space Research Organisation (ISRO) would launch its most ambitious suborbital — less than the usual orbit- test flight — Geosynchronous Satellite Launch Vehicle (GSLV) Mark III.

It will be an unmanned crew module. This will unleash India’s dream of sending its astronauts into space come true.

“We will comeback soon with an unmatched module in the next 45 days. GSLV Mark III will be one of the heaviest indigenous launch vehicles,” said K. Radhakrishnan, Chairman, ISRO, after the launch of PSLV C26, IRNSS-1C, the third satellite of the Indian Regional Navigation Satellite System from the first launch pad of Satish Dhawan Space Centre in Sriharikota.

The GSLV Mark III will help ISRO put heavier communication satellites of INSAT-4 class into orbit. These satellites weigh anywhere between 4,500-5,000 kg. The vehicle is 42.4 metre tall compared to the other GSLV which is 49 metre. It will be a three-stage vehicle.

“We are already working on this next launch. The work is completed and in testing stages,” Y.S. Prasad, Director, SHAR, said.

Terming the Mark III mission as most important and challenging, M. Chandradathan, Director of Liquid Propulsion Systems Centre of ISRO, said: “It is one of the heaviest indigenous launch vehicles that is been developed till date.”

The launch of GSLV Mark III will enhance India’s capability to be a competitive player in the multimillion dollar commercial launch market.

The vehicle envisages multi-mission launch capability for GTO (geo transfer orbit), LEO (low earth orbit), Polar and intermediate circular orbits.
