During the weekend the lander Philae resumed communications from the surface of the comet 67P/Churyumov-Gerasimenko. It’s been almost exactly seven months since Philae ran out of battery power and, because its position didn’t allow it to recharge them using its solar panels, had gone into hibernation. Now ESA is preparing new plans to try to make the most of the period in which the comet will be close enough to the Sun to provide the energy needed for Philae to work.
