The Indian Space Research Organisation has concluded that a
defective regulator in one of the four strap-on engines down its GSLV launcher on July 10 (INSAT-4C Failure).
The manufacturing defect was "inadvertent" and escaped
the best and established inspection procedures of the space agency,
leading to inadequate thrust; loss of the Insat-4C satellite along with
the launcher, both worth over Rs 250 crore, according to the Department
of Space Secretary and ISRO Chairman, Mr G. Madhavan Nair.
Mr Nair said ISRO would temporarily lease capacity on a foreign satellite
to accommodate the prime user of Insat-4C, the satellite lost on the GSLV
in July. It would do this once Sun TV put up its ground system and signalled its readiness.
Sun TV had booked seven of the 12 transponders on 4C to launch its DTH plans.
Meanwhile, it is building INSAT-4CR as a substitute to the lost 4C. It is converting one of its Gsats under assembly into a 12-transponder 4CR. The satellite will be launched from Sriharikota in June 2007.
