As NASA's MESSENGER spacecraft drew closer to Mercury for its historic first flyby, the spacecraft acquired this image showing a variety of surface textures, including smooth plains at the center of the image, numerous impact craters and rough material that appears to have been ejected from the large crater to the lower left.

The more than 1,200 images acquired by MESSENGER will assist in the scientific study of the history and evolution of the innermost planet.Image Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington?
