 Rosetta mission: Philae goes to sleep on comet as batteries run out 
 
 The Philae lander sitting on Comet 67P/Churyumov–Gerasimenko has run out of power after a successful last-ditch attempt to nudge it into better sunlight apparently came too late to charge its batteries and keep systems up and running. After the batteries run out, Philae will remain on the comet in a hibernation mode for the coming months. Controllers still haven't been able to pinpoint its position, but photos indicate it's next to a cliff that is largely blocking sunlight from reaching two of its three solar panels.

 The bad news: Scientists at the European Space Agency still don't know exactly where the lander is on the comet and are anxiously hoping its batteries hold out long enough for them to get the mining data and adjust the spacecraft's position. The landing had left Philae surrounded by rocks with only a sliver of light reaching one of its smaller solar panels. Despite the awkward landing, by Friday Stephan Ulamec, Philae lander manager, estimated that 80% of the science Esa was hoping for had been achieved. The comet is on a 6 1/2-year elliptical orbit around the sun.
– The spacecraft that landed on a comet yesterday is still talking to scientists, but its battery is expected to conk out soon. In what could be a last-ditch effort to save the mission, scientists with the European Space Agency say they'll try to make the Philae lander essentially hop to a different spot—one in which it might get more juice in the form of sunlight for its solar panels, reports the Guardian. Researchers still don't know exactly where the lander is, only that it's surrounded by rocks blocking most sunlight, perhaps next to a cliff, reports the BBC. In the meantime, the lander has begun drilling about 10 inches deep into the comet to collect samples that scientists would love to analyze, given that they are presumably billions of years old, reports the AP. The question is whether the battery will hold out long enough to transmit any data, while the very act of drilling is draining it further. "Maybe the battery will be empty before we contact again," says Stephan Ulamec, head of the lander mission. The battery isn't expected to last beyond tomorrow, but if ESA is able to shift the lander to a sunnier locale, the data collection could go on for months. (The landing hit a few glitches, including anchoring harpoons that didn't fire.)
