The European Space Agency’s Rosetta mission took this photo, and another science fiction dream becomes real. Click on it to enlarge. The ship is preparing to send a lander to the surface of this comet (called Comet 67P/Churyumov-Gerasimenkoin) in November. Thanks to Bad Astronomy blog for calling my attention to the image. The comet is 50 kilometers away in this photo, and comet itself is 3.5 to 4 kilometers long. It’s got an odd shape.
