Panaji, Aug 30 - India Sunday decided to terminate its first unmanned moon mission as contact could not be re-established with the spacecraft Chandrayaan, Indian Space Research organisation (ISRO) Chairman G. Madhavan Nair said, adding that he would meet the prime minister next week to brief him about the development.

'We are disappointed with what has happened, but we have managed to salvage a large volume of data,' Nair told reporters here.

'We are content with the result,' he said, adding that nearly 95 percent of the mission's objectives have been completed.

'Nearly 70,000 images of the moon have been captured during the mission. We were also conducting joint experiments with National Aeronautics and Space Administration (NASA) scientists and sharing signals received from our spacecraft,' he said.

Chandrayaan-1, launched in October 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.

Nair said a high-level committee was appointed to probe the failure, adding that the exact details about the reasons which led to Chandrayaan's failure could not be figured out in the absence of telemetry signals, which provide crucial indicators.
