Our lander’s asleep
http://blogs.esa.int/rosetta/2014/11/15/our-landers-asleep/
With its batteries depleted and not enough sunlight available to recharge,
Philae has fallen into 'idle mode' for a potentially long silence. In this
mode, all instruments and most systems on board are shut down.
"Prior to falling silent, the lander was able to transmit all science data
gathered during the First Science Sequence," says DLR's Stephan Ulamec,
Lander Manager, who was in the Main Control Room at ESOC tonight.
"This machine performed magnificently under tough conditions, and we can be
fully proud of the incredible scientific success Philae has delivered."

/ 01:36 CET, not long before the scheduled communication loss that would have
happened anyway as Rosetta orbited below the horizon.
From now on, no contact would be possible unless sufficient sunlight falls on
the solar panels to generate enough power to wake it up.
The possibility that this may happen was boosted this evening when mission
controllers sent commands to rotate the lander's main body, to which the
solar panels are fixed. This may have exposed more panel area to sunlight.
The next possible communication slot begins on 15 November at about 10:00 UTC
/ 11:00 CET. The orbiter will listen for a signal, and will continue doing so
when its orbit enables communication visibility in the future.
The hugely successful Rosetta mission will continue, as the spacecraft tracks
comet 67P/C-G on its journey to the Sun. Rosetta is the first spacecraft to
rendezvous with and orbit a comet and has already returned incredible
scientific data.
