GSAT-5P Launch Failed

Advanced communication satellite GSAT-5P failed after the rocket (GSLV -F06) crashed into the Bay of Bengal  just within 30 seconds at 4:16Pm today.

The Rs 125 crore GSAT-5P satellite weighing 2,130 kg will serve the needs of the telecommunication sector and the weather department, the Indian Space Research Organisation (ISRO) said. It will eventually retire the INSAT-2E satellite that was sent up in 1999.

History:

The GSLV rocket has three stages. The first stage is fired by solid fuel. The four strap on motors give additional thrust during the lift-off and the initial phase of the rocket's flight.

The second stage is fired by liquid fuel. The third stage, which is more complex than the others, involves the cryogenic engine powered by liquid hydrogen as fuel and liquid oxygen as oxidiser.

The GSLV rocket is 51 metres tall and weighs 418 tonnes.

The GSAT-5P satellite, with a life span of over 13 years, has 36 transponders - automatic receivers and transmitters for communication and broadcast of signals. Its successful launch will take the agency's transponder capacity to about 235 from the 200 currently in the orbit.
