GSLV MkIII alias LVM3
GSLV MkIII alias LVM3 is a heavy launcher being developed by ISRO,which will be capable of placing 4 ton class satellites into geosynchronous orbit. Once made operational, India would achieve complete self reliance in launching satellites. The LVM3 will have an indigenous cryogenic stage of higher capacity than GSLV.
First Experimental Flight (LVM3-X)
The first experimental flight of India's next generation launch vehicle GSLV Mk-III was successfully conducted on December 18, 2014 from SatishDhawan Space Centre SHAR, Sriharikota. Also known as LVM3-X/CARE mission, this suborbital experimental mission was intended to test the vehicle performance during the critical atmospheric phase of its flight and thus carried a passive (non-functional) cryogenic upper stage.
The mission began with the launch of GSLV Mk-III at 9:30 am IST from the Second Launch Pad. About five and a half minutes later, the 3775 kg Crew Module Atmospheric Re-entry Experiment (CARE) payload was carried to the intended height of 126 km. Following this, CARE got separated from the upper stage of GSLV Mk-III, 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.
Two massive S200 solid strap-on boosters, each carrying 207 ton of solid propellants, ignited at lift-off, functioned normally and got separated 153.5 s later. L110 liquid stage ignited 120 s after lift-off, while the S200 motors were functioning and carried forward the vehicle for the next 204.6 s.
CARE separated from the passive C25 cryogenic upper stage of GSLV Mk-III 330.8 s after lift-off and began its guided descent for atmospheric re-entry. With the successful LVM3-X/CARE mission, the vehicle has moved a step closer to its first developmental flight with the functional C25 cryogenic upper stage.
