Out beyond the orbit of Mars, on its way to rendezvous with comet 67/P Churyumov-Gerasimenko, ESA's Rosseta spacecraft has just flown past asteroid Steins. Here's a brief movie
of the encounter. We've grown so used to seeing scenes like this in SF movies that it takes a small effort of imagination to kindle our sense of wonder and remember that this is the real deal: real rock, real spacecraft.
Is it just me, or does it look like there's a face carved on the back side of the asteroid as it dwindles into the outer dark?
