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. http://photojournal.jpl.nasa.gov/catalog/PIA19204
