Great news indeed! smile.gif Will be interesting to see the details of the recovery & fault analysis.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Doh! Look what I found out here:

http://www.tesis.lebedev.ru/status.html

30th december 2009

Today we had the last meeting of the GOGU (Which is the Lead Operation Team). According to them they couldn't confirm yesterday's announce of Roscosmos about the restoration of Koronas-Foton. The satellite continues being in its previous state and the last contact occured on 10th of december.

Log of the events (English, Google translate):

How utterly bizarre. Does this mean Roscosmos should no longer be considered a credible source? blink.gif

I really don't know how to comment this. My personal opinion is that there is some kind of miscommunication between Koronas-Foton engineering team and Perminov.

Koronas-Foton entered the orbit with a maximum illumination, but engineers were unable to restore the performance of the spacecraft. TESIS team confirms that there is no radio link with the spacecraft since December 11th 2009. Actually, they are not talking about "restoring the science program". They are talking about obtaining a radio signal from the spacecraft. Koronas-Foton is silent.

There's still no explaination why Roscosmos (specifically its head Anatoly Perminov) told us that engineers have restored the functionality of Koronas-Foton and there is a radio link between the spacecraft and Earth controllers.

I also don't have any good explanation.
But think about: when was the last time you heard any bad news from official Roscosmos sources?

The answer to your question is: When Phonos-Grunt got delayed for two years. It wasn't announced on the front page, but it's still on the website of Roscosmos - though on a well hidden page.
