Flight testing of the Indigenous Cryogenic Stage in GSLV-D3 Mission not successful

The flight-testing of the indigenous Cryogenic Engine and the Stage conducted in the Geosynchronous Satellite Launch Vehicle GSLV-D3 this afternoon (April 15, 2010) was not successful.

GSLV-D3 vehicle lifted off as planned at 16:27 hrs after a countdown procedure lasting for 29 hours. The countdown went off as planned. GSLV-D3 vehicle performance was normal up to the end of the second stage (GS2) till 293 seconds.

Afterwards, the Cryogenic Stage was to ignite and burn for about 720 seconds to provide the necessary velocity to inject GSAT-4 Satellite into the intended Geosynchronous Transfer Orbit. It is yet to be ascertained whether the cryogenic engine did ignite. The vehicle was seen tumbling, lost altitude and finally splashed down in the sea.

Detailed analysis of the flight data is being carried out to find out the exact reasons for the failure and take corrective measures to realise the next flight test of the indigenous Cryogenic Engine and Stage within the next one year.
