August 29, 2009 – Chandrayaan-1 Mission Terminated
ISRO lost radio contact with Chandrayaan -1. After failing to re-establish contact for more than 24 hours, ISRO terminated the mission. Though this news is unexpected for all of us Chandrayaan – 1 achieved 95% of its objectives.
Overall, during its ten months of existence, Chandrayaan -1 completed 312 days in orbit and provided large amount of data. It was declared two years mission which is abruptly ended now. Chandrayaan-1 had completed more than 3400 revolutions around the moon. It had dispatched over 70,000 images of the moon surface.
The mission is abruptly ended but all the data was downloaded from the spacecraft on a regular basis and no scientific data is lost. John Yembrick, public affair officer (space operations) NASA headquarters, said, "NASA has obtained an abundance of data during our operations. Work is on to analyze that information."
The reason of termination of Chandrayaan-1 is now known that this was because of a miscalculation of the Moon’s temperature that had led to faulty protection. Read More
