Panaji, Aug 30 - India Sunday decided to terminate its first unmanned moon mission as contact could not be re-established with the spacecraft Chandrayaan, a top space official said here.

'We are disappointed with what has happened, but we have managed to salvage a large volume of data,' Indian Space Research Organisation (ISRO) chairman G. Madhavan Nair told reporters here.

'We are content with the result,' he said.

Chandrayaan-1, launched last year, sent last message 00.25 IST Saturday and the space agency's Deep Space Network (DSN) lost radio contact with the spacecraft five minutes later.
