The comet-chasing Rosetta spacecraft has taken the first close-up snapshots of the asteroid Steins, revealing it is an ancient, cratered rock shaped like a diamond. Launched by the European Space Agency four years ago, Rosetta came within 800 kilometres of the tiny space rock on Friday. Steins, a rare type of asteroid located in the main asteroid belt between Mars and Jupiter, is Rosetta's first scientific target on its way to rendezvous with Comet 67P/Churyumov-Gerasimenko in 2014.
