Chandrayaan had already done 95% of its tasks, says Isro chif

India’s first moon mission Chandrayaan-I, came to an abrupt end early on Saturday and it was slated to be a two year mission , Isro chairman Madhavan Nair said that nearly 95% of Chandrayaan ‘s scientific goals had already been accomplished in less than a year. ISRO's Deep Space Network near Bangalore received the data from the spacecraft up to 0025 hours after which it lost contact with earth.
Having completed bulk of the scientific mission ,Isro chief spokesperson S Satish said that even if Chandrayaan-I, had remained in orbit for another year, nothing much would have been gained. In the hostile lunar environment, It is impossible for a spacecraft to survive for long periods, “He said.
The spacecraft was launched in the moon's orbit from ISRO's Satish Dhawan Space Centre Sriharikota on October 22, 2008. We have lost contact with the spacecraft and the mission is over," Project Director of the Chandrayaan-1 mission M Annadurai said. Indian Space Research Organisation (ISRO) however claimed that the moon mission had achieved most of its objectives. Though there was no official word on the cause of the loss of contact, space experts, who declined to be identified, said it could be due to a power problem in the spacecraft being hit by a some space object. Chandrayaan-1 has done its job technically about 100%. Scientifically, it has done almost 90-95% of its job, "Mr Annadurai added.
Mission Chandrayaan-I’s ride has been a bumpy one in the last few months. There was an overheating problem necessitating the deactivation of some of the 11 payloads. Then on April 26th the star sensor started malfunctioning which affected the spacecraft’s orientation.
