Scarlatti is a peak-ring basin with a diameter of 132 kilometers. Just north of the inner peak ring on the basin’s floor is a large oblong pit, shown here in the highest resolution ever obtained. The large pit may have formed as a volcanic collapse feature, and this high-resolution view shows many hollows located on the pit’s wall. Members of the MESSENGER team are using images like this one to unravel the geologic relationship between Scarlatti’s pit and these newly seen hollows.

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 250-meter/pixel (820 feet/pixel) morphology base map or the 1-kilometer/pixel (0.6 miles/pixel) color base map. It is not possible to cover all of Mercury’s surface at this high resolution during MESSENGER’s one-year mission, but several areas of high scientific interest are generally 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.

During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER’s science goals.
