France: After spending seven long months in hibernation on the surface of Comet 67P/Churyumov-Gerasimenko, Rosetta's lander Philae has finally woken up, the European Space Agency reveals. The signals were received on June 13 at the ESA's European Space Operations Centre in Darmstadt, Germany, at 22:28 CEST. Philae "spoke" for 85 seconds with its team on ground, via Rosetta, in the first contact since going silent in November 2014. Using the hashtag #WakeUpPhilae, the lander tweeted: "Hello Earth! Can you hear me?"

"Philae is doing very well: It has an operating temperature of -35ºC and has 24 Watts available. The lander is ready for operations."

More than 300 data packets have been analysed by the teams at the Lander Control Center at the German Aerospace Center (DLR). Analysis has revealed that Philae also must have been awake earlier also: "We have also received historical data – so far, however, the lander had not been able to contact us earlier." The scientists are now waiting for Philae’s next communication, which would enable them to fetch more than 8,000 data packets stored in the lander’s mass memory.
