Summary

Description	English: Date acquired: May 05, 2013 Image Mission Elapsed Time (MET): 10039124 Image ID: 4007460 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 16.63° Center Longitude: 156.9° E Resolution: 39 meters/pixel Scale: This image is 57 kilometers (35 miles) from corner to corner Incidence Angle: 30.4° Emission Angle: 11.2° Phase Angle: 28.1° Of Interest: This high-resolution image shows a region of the southern rim of the large Caloris basin. In the center is an irregularly shaped depression believed to be a pyroclastic volcanic vent. In this previously posted image, you can see this feature in the upper right as having a reddish color with a dark center. What is this dark, low reflectance material (LRM)? That is a question being actively asked by the MESSENGER team. Most pyroclastic vents don't have this dark material, but other features do show small outcrops of it, such as Berkel and Seuss. 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 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.
