"We have sent up a command, the probe has replied," an ESA spokesman said on Wednesday in Darmstadt. "Now is clear" that "Phobos-Grunt 'is still alive."
Darmstadt - after numerous attempts has succeeded the European Space Agency ESA contact to the misguided Russian Mars Moon probe "Phobos-Grunt". "We have sent up a command, the probe has replied," an ESA spokesman said on Wednesday in Darmstadt. "Now is clear 'that 'Phobos-Grunt' still alive'."
It remains to be seen whether the to save circular space probe was for two weeks in orbit, said René Pischel, head of the Russian delegation to ESA: "the patient is though not dead, but he is as ill, we do not know yet." The signal contained no telemetry data. "We make a renewed attempt at coming night", so Pischel.
Geglückt, the contact is out on Tuesday evening from the ground station in the Western Australia Perth. "The angle of 'Phobos-Grunt' is from there conveniently", a spokeswoman in Moscow, "and the solar module of the spacecraft receives sufficient sunlight." said
Just a few hours before the Russian Space Agency had informed Russian Federal Space Agency in Moscow, that the 13.5 tonnes and 120 million euro expensive space probe "Phobos-grunt" as good as lost was and probably fall in the next few weeks on the ground. The US Canadian space surveillance command Narad was even assumed that the probe could crash on 26 November already.
After reaching orbit on 9 November, the engines of equivalent 125 million euro expensive "Phobos-Grunt" for the onward flight to the Martian moon of Phobos had not ignited. Since there was no contact more. The Russians had asked for help therefore the ESA.

Thank you
I tried google.translate but it turned out not too well.
Experts believe that the Mars mission has failed as the last "window of opportunity" for sending the probe on course to Mars closed on Monday, but obtaining telemetric data from the spacecraft could help to find out the causes of the failure and make adjustments for future interplanetary missions.
The deputy head of the Phobos-Grunt project chief scientist, Alexander Zakharov of the Space Research Institute, said the telemetry would show whether the spacecraft could be "reanimated" and used in another research mission.
He said that if the spacecraft is fully operational, the best scientific mission for it would be to study a near-earth asteroid.

Well browsing into the propulsion design of Phobos-Grunt suggests its main SPD-140 electric engines is a kind of ion thruster and not a more traditional rocket like the Centaur restartable RL-10 engine Curiosity is using for earth escape velocity. This is a slower reactive thrust so a longer trajectory may be it's only flight option and that window may have closed.

That would be a great idea.
Although i cant help but wonder why in 2011 we have this trouble in the first place.
