Scarlatti Crater


The peak-ring basin Scarlatti is seen at the center of this image. While Scarlatti has a typical peak ring in many respects, in the northeast section it transitions to a large (approximately 30 km) pit surrounded by high-reflectance material. This pit may be the site of past explosive volcanic activity.

This image was acquired as a targeted 11-color image set. Acquiring 11-color targets is a new campaign that began in March 2013 and that utilizes all of the WAC's 11 narrow-band color filters. Because of the large data volume involved, only features of special scientific interest are targeted for imaging in all 11 colors.

Hollows in Scarlatti's Basin


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.
