Chandrayaan-1 lost Radio contact with Earth

Earth has lost another Satellite, Chandrayaan-1. According to numerous reports in Indian media, contact was lost with the lunar orbiter Chandrayaan-1 abruptly -- in the middle of a communications session with Earth -- at 1:30 Indian time on Friday (Thursday, August 27, at 20:00 UTC). India's communications antenna at Byalalu had received data from the spacecraft up to that taken at 00:25 IST (18:55 UTC), including the results of a recent bistatic radar experiment conducted jointly with Lunar Reconnaissance Orbiter.

But Chandrayaan-1 has done its intended work succesfully 90% of the work. Chandrayaan-1 was launched on October 22, 2008 and had been intended to conduct a two-year primary mission. During 312 days at the Moon it orbited more than 3,400 times and returned more than 70,000 images, plus other data. More than half of its instruments were provided by (or in cooperation with) ESA and NASA; several were copies of those on ESA's SMART-1, and one was a duplicate of the Mini-SAR instrument now in orbit on NASA's Lunar Reconnaissance Orbiter. ISRO has posted some images and data from the mission. The photos can be seen by Clicking Here.
