The European Space Agency apparently hasn't given up on Philae that's currently hibernating on comet 67P/Churyumov-Gerasimenko. In a new post on its website, the agency has detailed a highly technical game of "Where's Waldo?" that it's been playing since last year. See, the lander's harpoons failed to deploy upon touchdown, and it ended up bouncing away from its landing site until it reached underneath one of the comet's cliffs. In addition to being hidden in the shadows, the lander is relatively tiny -- even if Rosetta's (its partner spacecraft) cameras managed to catch it on film, it would appear as a small bright speck and nothing more.
