Image Mission Elapsed Time (MET): 213501587 Image ID: 235044 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 25.59° Center Longitude: 166.7° E Resolution: 88 meters/pixel Scale: Atget is 100 km (62 miles) in diameter Incidence Angle: 69.4° Emission Angle: 60.1° Phase Angle: 129.1°

Of Interest: At a diameter of 100 km, the crater Atget is one of the largest craters within the Caloris basin. This targeted NAC observation provides our first high-resolution view of Atget's low-reflectance floor and ejecta, which were likely excavated from beneath the surficial plains when Atget formed. Check out Atget in this enhanced color view of Caloris. It's the dark blue crater just south of Caloris's center.

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.
