  • Satellite Debris Recovery?

    NEW DELHI: Battling rough sea, poor visibility, underwater currents and sea bed disturbances for over 100 days, Indian scientists have managed to recover all the four strap-on motors of the Geo-Synchronous Launch Vehicle (GSLV), that fell into the Bay of Bengal shortly after taking off from Sriharikota on July 10 this year.

    According to Union Minister for Science and Technology and Earth Sciences (MS&T and ES), this is the second such recovery in the history of space programme, after a similar operation was taken up by European Space Agency (ESA) in 1996 following the failure of its maiden test flight Ariane 5. The GSLV debris recovery effort has achieved a success rate of 98 per cent, he said. “The recovery will enable ISRO to analyse the reasons for the failure of GSLV,” Sibal said.

    Scientists from the National Centre for Antarctica and Ocean Research (NCAOR) Goa and National Institute of Ocean Technology, Chennai launched the rescue efforts on July 15 following a request from Indian Space Research Organisation (ISRO) to recover the debris.

    Sonar surveys were conducted based on the four impact predicted points provided by the ISRO. These four points represent the four L40 strap-on engines, one of which was a failure engine that caused the mishap.

    About 550 divers and four ships — ORV Sagar Kanya, CRV Sagar Purvi, CRV Sagar Paschimi and a chartered vessel, Akademik Boris Petrov — were pressed into the operation. “We have recovered all parts of the strap-on motors, except for a small electronic device having computer,” said M Sudhakar, a NCAOR scientist.

    The GSLV-F02 carrying the INSAT-4C communication satellite veered from its projected path within a minute of take-off and exploded mid-air scattering debris over the sea.
