Rosetta’s lander Philae has woken adult after 7 months in hibernation on a aspect of Comet 67P/Churyumov-Gerasimenko.

The signals were perceived during ESA’s European Space Operations Centre in Darmstadt during 22:28 CEST on 13 June. More than 300 information packets have been analysed by a teams during a Lander Control Center during a German Aerospace Center (DLR).

“Philae is doing really well: It has an handling heat of -35ºC and has 24 Watts available,” explains DLR Philae Project Manager Dr. Stephan Ulamec. “The lander is prepared for operations.”

For 85 seconds Philae “spoke” with a group on ground, around Rosetta, in a initial hit given going into hibernation in November.

When analysing a standing information it became transparent that Philae also contingency have been watchful earlier: “We have also perceived chronological information – so far, however, a lander had not been means to hit us earlier.”

Now a scientists are watchful for a subsequent contact. There are still some-more than 8000 information packets in Philae’s mass memory that will give a DLR group information on what happened to a lander in a past few days on Comet 67P/Churyumov-Gerasimenko.

Philae close down on 15 Nov 2014 during 1:15 CET after being in operation on a comet for about 60 hours. Since 12 Mar 2015 a communication section on orbiter Rosetta was incited on to listen out for a lander.
