Behold Bartok - Nasa Messenger Mission Image: Release Date 7 Dec 2011

Date acquired: November 09, 2011 Image Mission Elapsed Time (MET): 229323911 Image ID: 990827 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: -28.84° Center Longitude: 224.3° E Resolution: 120 meters/pixel Scale: Bartok crater has a diameter of 117 km (73 miles) Incidence Angle: 31.0° Emission Angle: 51.8° Phase Angle: 79.3° Of Interest: This oblique view of Bartok accentuates the central peaks and terraced walls of this complex crater. Bright material is visible on the central peaks, which may be due to the presence of hollows, like those that have been discovered on the central peak-ring mountains of the Raditladi impact basin and at many other locations on Mercury. This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions 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.
