MESSENGER Image: Unnamed Peaks on Mercury

The mounds in this image are the central peak of an unnamed crater approximately 47 km in diameter, imaged at such high resolution (18 meters/pixel) that only the crater’s interior can be seen. Central peaks are of great interest because they expose material that originally resided at depth in the target material.
