This image, just captured last week, shows Mercury's hollows in the highest resolution yet achieved! These hollows are located on the wall of Sholem Aleichem, within a region of low-reflectance material.
This image was acquired as part of the MDIS low-altitude imaging campaign. During MESSENGER's second extended mission, the spacecraft makes a progressively closer approach to Mercury's surface than at any previous point in the mission, enabling the acquisition of high-spatial-resolution data. For spacecraft altitudes below 350 kilometers, NAC images are acquired with pixel scales ranging from 20 meters to as little as 2 meters.
