Philae has woken up after seven months in hibernation on Comet 67P/Churyumov–Gerasimenko. Hidden by shadows, Philae shut down on 15 November 2014 at 00:36 GMT after completing its main science operations sequence on the comet when the primary battery expired as expected after about 60 hours.
Philae bounced across the surface a few times, possibly clipping a crater rim, and wound up on its side under a cliff. The odds of re-establishing contact were slim, but we were assured that was OK because the solar panels were a last-minute addition; all the science team was originally hoping for was that initial 60 hours on the comet.
Looks like they’ll get a lot more.
