ISRO teams analysing data to pinpoint GSLV failureIndia's top space scientists are analysing data to find out what caused the failure of Geosynchronous Satellite Launch Vehicle mission and an expert committee is likely to be formed soon to give a report on it.
"Teams are looking at the data to find out the reason for what happened," said Indian Space Research Organisation spokesman S Satish.
"A failure analysis committee is likely to be constituted in the next one or two days," he said.
In a major setback, GSLV-F06 powered by Russian Cryogenic stage, with GSAT-5P communication satellite on board, failed in its mission on Saturday following a technical problem soon after the liftoff from the Sriharikota spaceport in Andhra Pradesh.
The GSAT-5P, meant to give a boost to communication services, including television, telephone and telemedicine, was originally scheduled for launch on December 20 but was postponed a day earlier after a leak was noticed in the cryogenic stage during pre-countdown checks....being a human...

GSLV failure a blow to ISRO's space ambitionsIndia's space programme suffered a serious setback on Saturday evening when a Communication Satellite launched from Sriharikota exploded mid-air. It was the second satellite failure in six months. Scientists are divided, but the bigger worry is: What will happen to India's moon mission?
The Geosynchronous Satellite Launch Vehicle was launched with high hopes by the ISRO scientists. However, 47 seconds later hope turned into horror as the onboard computer lost control of the actuation system. Back at the base in Sriharikota, scientists had no option but to press the self-destruct button to abort the ill-fated flight.
But ISRO does not label this is as a catastrophe. Former ISRO Chairman Dr K Kasturirangan believes that this failure should not be a cause of concern.
There are others who beg to differ. The satellite the rocket was carrying was to be used in telemedicine, telecom & weather services, and TV.
“It's a major setback and it takes us back to one or two years as we have to start the entire thing once again”, said Dr CB Devgan, Director, SPACE.
The launch failure also comes as a big blow to ISRO's loftier ambitions - such as the moon mission. The failure of two GSLVs in a span of eight months is a cause of worry for the scientists at ISRO given the fact that it is going to be the launch vehicle for Chandrayaan-II in 2013.
On April 15th, the GSLV-D3 launch carrying an indigenous cryogenic engine failed. All in all, only two GSLVs out of seven launches have been successful. Clearly, there is a ghost in the machine for ISRO....being a human...

GSLV failure 'tragic, a major setback'Describing the failure of the GSAT-5P communication satellite launch on Saturday as 'very tragic', India's top space scientists and strategic thinkers said the launch vehicle going up in flames soon after the lift off was 'a major setback' for ISRO.
Senior space scientist Professor Yashpal, in his first reaction to the failure of the satellite launch, said, "It is very tragic. I think something has happened in early stages. I have never heard of such a thing, as we have had several successes before."
Noting that the GSLV-F06 launch vehicle had disintegrated in its initial stages itself, Yashpal said, "We did not get up to the liquid stage. It is terribly sad that something somewhere has gone amiss. A lot of data is available. So they will be able to find out what went wrong."
He felt that this was 'a freak mishap' as the early stages of the launch vehicle had been tested several times by India and have a 100 per cent success rate.
"It (the problem in the launch vehicle) cannot be something fundamentally wrong. It must be something big. It is unfortunate. This is an accident of some sort," he said.
Former ISRO engineer Madan Lal, in his remarks, said there seemed to be 'some technical problem' in the first stage of the launch vehicle and not with the Russian cryogenic stage that India was using for the satellite launch this time....being a human...
