After traveling 4 billion miles, accomplishing an exhilarating landing on a 84,000-mph moving target, and, after 57 hours of work in an unfortunately dark location, successfully sending a valedictory round of data, the ESA’s history-making Philae probe falls into slumber. “We still hope that at a later stage of the mission, perhaps when we are nearer to the Sun, we might have enough solar illumination to wake up the lander and re-establish communication.” Rest well, little lander — ya did good.
