( WITH UPDATED INFORMATION)
I observed the video of the launch of GSLV F06 for some time and discovered some facts associated with the failure of launch.
While observing minutely the Launch video of the GSLV F06 with GSAT 5p at 1600hrs,on 25th Dec 2010,
I observed some key details contributing to the failure of the launch.
NOTE-
FIRST IMAGE FROM TOP IS TAKEN FROM THE FRAME OF THE LAUNCH PAD
WHILE REST IMAGES OBTAINED FROM THE VIDEO SHOWS THE LAUNCH AS VIEWED FROM OPPOSITE SIDE
1*) After 47-49 to 50 seconds from launch, around 4 connectors at the first stage which carry the signals from main computer system of GSLV to components snapped off due to unknown reasons.
1**) The Heat shield of the satellite at the very top of GSLV ( blasts out suddenly )
See the VERY FIRST IMAGE FROM TOP. This was the first event in the failure.
This heat shield blast was not visible in the frame of launch taken from opposite of launch pad( i.e from viewers gallery). So I mentioned that the Boosters separated at first but actually they got burst after the heat shield.
1) At 49 seconds from Launch- A Booster got separated from the GSLV body ( As seen from the second image which is invisible to those at the launch pad side) which bend the Launch vehicle heading alignment towards Right from the normal path.
2) At 50 seconds from Launch, the dark white plume to the South of Main Body of GSLV shows confirmed UNUSUAL SEPARATION ( As seen in third image). The GSLV continued to ascent with a deviated path.
3) At 52 seconds from launch, ENTIRE path of Booster # 1 after separation with its present location is also seen
Also at this moment, there is unusual brightening at the top of the visible cloud( As explained in the fourth image)
4) At 54 seconds from launch and apx 5 seconds after separation of Booster#1, Now remaining three boosters also are clearly seen in the image. The previous explosion at 52 second separated the remaining booster from the main body of GSLV.
While the upper part of GSLV still climbs in sky ( As seen in the fifth image)
5) At 56 seconds from launch,Booster #2,3,4 are clearly seen in the picture while booster #1 goes behind the cloud
ALSO THERE IS A STRONG EXPLOSION AT THE TOP OF GSLV MAIN BODY IN THE GSAT 5P REGION.THIS MUST BE TIME WHEN RANGE SAFETY OFFICER AT ISRO PRESSED THE DESTRUCT BUTTON OF ROCKET TO AVOID IT FALLING ON LAND.
( AS SEEN FROM sixth IMAGE)
6) At 58 seconds from launch, BOOSTER #1,2,3,4 keeps ascending while there IS INCREASE IS VELOCITY OF UPPER PART OF GSLV MAIN BODY. THIS IS RELATED TO THE EXPLOSION CAUSED DUE TO DESTRUCTION COMMAND GIVEN BY ISRO
7) At 95 seconds from the launch, all the boosters start falling back on the earth while the upper part of GSLV climbs high in sky. This portion later falls down on the earth. ( See image no.8 from top)
So,
GSLV F06 failed due to
* SNAPPING OF CONNECTORS ALL OF A SUDDEN LEADING TO LOSS OF SIGNAL TO THE BOOSTERS
* THE HEAT SHIELD THEN BROKE OFF FOLLOWED BY BOOSTER SEPARATION
* TO AVOID RISK OF LAUNCH VEHICLE FALLING ON EARTH, RANGE SAFETY OFFICER PRESSED THE DESTRUCT COMMAND
( REASONS AS VERIFIED BY ISRO)
