PM congratulates team on successful mission

The Indian Space Research Organisation ended the year 2014 on a high note with the successful launch of the 630-tonne Geosynchronous Satellite Launch Vehicle-Mk III (GSLV Mk III). This will help the space organisation put heavier satellites and crew modules into orbit and help India become a competitive player in the multimillion dollar commercial launch market.

Prime Minister Narendra Modi congratulated ISRO scientists on the successful launch.

It was yet another textbook launch, with the rocket soaring into the sky precisely at 9.30 am from the second launch pad of the Satish Dhawan Space Centre here. On a sunny morning, the large rocket, with a thick orange flame at its tail, roared into the sky with a thunderous sound.

The main objective of the Rs 155-crore mission was to test the rocket’s atmospheric flight stability carrying around four tonnes of luggage.

GSLV Mk III was conceived and designed to make the research organisation self-reliant in launching heavier communication satellites of four-to-five tonnes of the INSAT-4 class.

The rocket had a three-stage engine with a lift-off weight of 630 tonnes. The first comprised two identical S-200 large solid boosters with 200-tonne solid propellant. This was strapped on to the second stage L110 re-startable liquid stage. The third stage was the cryogenic engine.

Soon after lift-off, ISRO will study the flight validation of the atmospheric flight regime of LVM 3 and also test the ability of the crew module to re-enter the Earth’s atmosphere with thermal resistance, parachute deployment in cluster formation, aero-braking system and apex cover separation procedures.
