Original Caption Released with Image:

This fascinating limb view shows Mercury's southern hemisphere. Highlighted in this image is Basho, with its dark halo and bright ray system, in the upper left, along with Han Kan and its prominent rays to the right, near the terminator.

This image was acquired as part of MDIS's limb imaging campaign. Once per week, MDIS captures images of Mercury's limb, with an emphasis on imaging the southern hemisphere limb. These limb images provide information about Mercury's shape and complement measurements of topography made by the Mercury Laser Altimeter (MLA) of Mercury's 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.
