Today's image features a color view of the southern pole of Mercury. About midway down the image, the edge of the large Chao Meng-Fu crater, which lies almost directly on the south pole, can be seen poking out from the shadows . Surrounding Chao Meng-Fu are Roerich, Lovecraft , Hurley and L'Engle craters. This image was obtained as part of the 11-color south polar imaging campaign, through which scientists hope to be able to use the relative brightness of the surface in different colors to understand its composition.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
