Philae lander off for good

At 11am this morning (CEST) the parts of the Rosetta spacecraft that communicate with the Philae lander, perhaps the best known part of the Rosetta mission, were turned off in order to save power in the final mission phase. Nothing has been heard from the lander since July 2015, but the communications gear on the Rosetta orbiter was nonetheless left powered up until now in the hope of receiving a signal.
