Lander Philae on Comet 67P has Gone Dark

The ESA has announced that the Philae lander on comet 67P has run out of juice and put itself to sleep until it can gather enough solar energy to resume operation. Since the lander is nestled against a cliff in the shadows, it's unknown when it will reactivate. ESA calls the misison a "scientific successs."

Professor Mark McCaughrean, senior scientific adviser to the ESA, told BBC Radio 5 live they were "hugely happy". He said: "All of the science instruments on board have done all the work they were supposed to do so we have huge amounts of data back on the ground now, which is really exciting. Philae could come back later as we move closer to the sun, and we get more light onto the solar panels up against the cliff we're at here in the shadows."
