It’s Me! Philae!

Philae comet lander wakes up after 7-month hibernation:

“Scientists had lost contact with the solar-powered probe after it was dropped on the icy comet 67P/Churyumov-Gerasimenko by its mothership Rosetta on Nov. 15. Philae’s battery ran out at about 60 hours after it landed next to a cliff that largely blocked sunlight from reaching the lander’s solar panels.

Scientists had hoped the probe would wake up again as the comet approached the sun, enabling Philae’s solar panels to soak up enough light to charge the craft’s main battery. But there were fears its mission would be cut short.

Any such fears ended late Saturday, when the European Space Operations Center in Darmstadt, Germany, received signals from the lander.

‘I’m not really surprised it happened, but if you wait for several months and then suddenly in the middle of the night you get a call saying, ‘We have a signal from Philae,’ it’s exciting,’ said Stephan Ulamec, project manager at the German Aerospace Center, or DLR. ‘We’re very happy.'”

That’s great news.
