Original Caption Released with Image:

The 173-km-diameter Aksakov basin was named in 2012, and has a prominent peak ring that hosts multiple hollows. A large portion of its peak ring is missing, however, destroyed when the crater in this image was formed. But this crater has interesting features of its own, including wall slumps and hollows on its smooth floor.

This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

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.
