This image from MESSENGER spacecraft covers a small area located about 115 km south of the center of Mansart crater. The smallest craters visible in the image are about the size of the 16-meter (52-feet) crater that will be made by the impact of the MESSENGER spacecraft. The impact will take place tomorrow, April 30, 2015.
Just left of center is a crater that is about 80 meters in diameter. The bright area on its right wall may be an outcrop of hollows material.
