Date acquired: May 10, 2011
<p>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°
</p><p>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 <a href="//commons.wikimedia.org/wiki/File:PIA10359_Caloris_Basin_-_in_Color!.jpg" title="File:PIA10359 Caloris Basin - in Color!.jpg">this enhanced color view of Caloris</a>. 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.
