Rosetta: The comet chaser

After a 10-year chase taking it billions of miles across the solar system, the European Space Agency's Rosetta spacecraft became the first probe to orbit a comet after arriving at its destination on August 6. The spacecraft recently took this image of comet 67P/Churyumov-Gerasimenko. In November, Rosetta will deploy a robotic lander to the comet's surface -- something that also has never been done before. The box on the right shows where the lander will touch down.
