GSLV Mk-III X : First Experimental Flight Successful

gslvmk3

The first experimental flight of India’s next generation launch vehicle GSLV Mk-III was successfully conducted on December 18, 2014 morning from Satish Dhawan Space Centre SHAR, Sriharikota. Also known as LVM3, this suborbital experimental mission was intended to test the vehicle performance during the critical atmospheric phase of its flight and this carried passive (non functional) cryogenic upper stage.

THE SUCCESS TALE 

The mission began with the launch of GSLV Mk-III at 9:30 am IST as scheduled and about 5.4 minutes later, carried its payload – the 3.8 ton Crew Module Atmospheric Re-entry Experiment (CARE) – to the intended height of 126 km. Following this, CARE separated from the upper stage of GSLV Mk-III and re-entered the atmosphere and safely landed over Bay of Bengal with the help of its parachutes about 20 minutes 43 seconds after lift-off.

The total budget of the experimental mission was Rs 155 crore, including the crew module, which cost Rs 15 crore. A few years back Isro had carried out a similar experiment, Space-capsule Recovery Experiment (SRE), on a smaller scale by PSLV in which the module had orbited around the earth for 15 days before entering back.

SIGNIFICANCE 

With this successful GSLV Mk-III X / CARE mission, the vehicle has moved a step closer to its first developmental flight with the functional C25 cryogenic upper stage. It will be the ISRO’s most powerful rocket, capable of putting four-tonne communication satellites into orbit. This launch was also an early test of a crew module being developed for human space flight.

India took the first step on Friday, 28th March 2014 towards the experimental mission of its gigantic GSLV-Mk III (Geo-synchronous Satellite Launch Vehicle-Mark III) when the rocket’s core stage, weighing more than 110 tonnes, was flagged off from the Liquid Propulsion Systems Centre, Mahendragiri, Tamil Nadu, to Sriharikota in Andhra Pradesh.

The GSLV-Mk III in this flight will carry a crew capsule without astronauts. The rocket will reach an altitude of less than 100 km. The capsule will return to earth with the help of parachutes. Its upper cryogenic stage will not fire. Instead of cryogenic propellants, the cryogenic stage would carry liquid nitrogen, which would be inert. The mission will take place in June or first week of July.

GSLV-Mk III is powered by an indigenous cryogenic engine. It can put a communication satellite weighing four tonnes into geo-synchronous transfer orbit or a 10-tonne satellite into low-earth orbit.  It will also serve as vehicle to carry astronauts to space after initial experiments.
