Phobos-Grunt: all but over, a letter from IKI

Currently, the spacecraft is rotating [tumbling] at the near Earth orbit, lowering every day, and we expect that it is to entry the atmosphere in several weeks. Lavochkin Association specialists will continue their attempts to establish connection with the spacecraft and send commands until the very end of its existence. We are working nevertheless on the issue of re-entry and probability of where and which fragments may hit the ground (if any). There is a sensitive matter that one of the scientific instruments (Messbauer spectrometer) contains radioactive material Co-57. However, the amount of Co-57 is about few (less than 10) micrograms, so that, according to our evaluations, no significant problems are is anticipated.

ESA station unable to establish new link with Phobos-Grunt
 
After establishing contact with Russia's Phobos-Grunt Mars mission earlier this week, ESA's tracking station in Australia received no signal from the spacecraft last night. ESA engineers are investigating the cause in close collaboration with Russian mission controllers.
Despite listening intently during four scheduled communication passes during the night of 24-25 November, ESA's 15 m-diameter dish antenna at Perth, Australia, did not receive any signals .
The slots for communication, timed to coincide when Phobos-Grunt was passing over in direct line-of-sight with the station, began at 20:12 GMT and ran until 04:04 GMT. Each lasted just 6-8 minutes, providing very limited windows for sending commands and receiving a response.
