Original Caption Released with Image:

This image of Mercury's southern hemisphere shows the large size variation and multiple generations of impact craters on Mercury. Mercury's southern hemisphere is easier to image due to MESSENGER's elliptical orbit, but this orbit also prevents acquisition of high resolution images like those taken in the northern hemisphere.

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. MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
