As MESSENGER passes progressively closer to Mercury, we see ever more resolved features in the images the spacecraft returns. Here, at a pixel scale of 9 meters, we see the eastern portion of an unnamed crater 13 km (8 mi.) in diameter. The wall of the crater is replete with smaller, superposed craters, some of which appear elongate possibly because they impacted on the larger crater's inclined wall. Interestingly, there are bright spots on the sunlight portion of this crater's wall -- which is where we might expect hollows to form.

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.
