GSLV Failure, Yes this does happen., Now & then

The Official Press Release from the ISRO is below and it describes that the GSLV “cannot complete its mission” ie. putting the satelitte on orbit. But, as it came to know the Liquid strap-ons were (seems to be ) the reason for this hitch too., (as was in 1999).

Date Released: Monday, July 10, 2006

India’s Geosynchronous Satellite Launch Vehicle (GSLV-F02), with INSAT-4C on board, was launched from Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharihota today (July 10, 2006).

The lift-off took place at 5:38 p.m. IST.
However, GSLV-F02 could not complete the mission.

The detailed analysis of the data received from the vehicle is being analysed to pinpoint the exact reasons.

The Anatomy of the ” Failure “
The second operational flight of the GSLV rocket that was to hurl the country’s heaviest satellite yet built , 36,000 km into space instead plunged into the sea, within a minute of launch from the country’s space port at Sriharikota.
One of the four strap-on motors, attached to the 49-metre-tall, 414 tonne GSLV did not give the required thrust forcing the rocket to deviate from its flight path by about 10 degrees. The project director, who found that the first stage did not separate from the upper two stages, pressed the button to destroy the rocket for safety reasons. “It appears from preliminary data that the pressure had dropped to zero in one of the four strap-on motors and it failed to give the required thrust to the GSLV,” Indian Space Research Organisation (ISRO) Chairman G Madhavan Nair said, after the mishap, the first major incident in 12 launches of the space agency.(considering 9 Succesful launches in Row with 6 Foreign Satelittes/Payloads)
Five years ago, the first experimental GSLV rocket had faced a pressure drop in one of the boosters, but the onboard computers aborted the rocket, barely two seconds before lift-off. ISRO top brass had then claimed that they had perfected the in-built safety systems to prevent a disaster.
On Monday it seemed like ISRO officials had a hint of a problem in the rocket, when they delayed the launch by almost one hour. But, they went ahead at 17:38 hours, to find television sets across the world beam the five-storeyed gigantic machine bursting into flames.

But,The strap-on Boosters is belived to have developed a snag well before the launch, and according to some reliable sources, its actually the executive decession and the political will that made to go ahead with the launch even after the strapons developed some pressure loss., (meaning the motor used for pumping fuel din’t worked upto the mark.) (but the pride of completing the mission on the announced day seems to have rushed the decassion rather than wait for the saftey check to complete) all said and done, such accidents do happen and cannot be parted with, So i personally think the ISRO guys will come up with more robust and efficent “on-board ” security measures……
