Mercury up close

NASA's MESSENGER spacecraft flew past Mercury and sent more than 1,200 high-resolution images back to Earth. This picture was taken at the closest approach to Mercury, when the spacecraft was at a distance of about 27,000 kilometers (about 17,000 miles). Read the whole story here, and look at the photo gallery.
