MESSENGER: MErcury Surface, Space ENvironment, GEochemistry, and Ranging
| Date acquired: April 07, 2012 Image Mission Elapsed Time (MET): 242296379, 242338160, 242338176, 242338192, 242379971 Image ID: 1617565, 1619567, 1619568, 1619569, 1621694 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 37.1° Center Longitude: 232.7° E Resolution: 32.5 meters/pixel Scale: Degas is approximately 53 km (33 mi.) in diameter. Incidence Angle: 68.5° Emission Angle: 15.6° Phase Angle: 52.8° Of Interest: Degas crater is shown here in spectacular detail. This high-resolution mosaic is made up of five separate images. The floor of the crater contains cracks that formed as the melt sheet cooled and contracted. Downslope movement of material on the central peaks and walls has exposed fresh, bright material. This mosaic is made up of images acquired as high-resolution targeted observations. 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. | |
