| Date acquired: January 23, 2012 Image Mission Elapsed Time (MET): 235766888, 235766929, 235766969 Image ID: 1300010, 1300011, 1300012 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 21.90° Center Longitude: 1.78° E Resolution: 57 meters/pixel Scale: De Graft crater is approximately 68 km (42 mi.) in diameter. Incidence Angle: 73.5° Emission Angle: 37.1° Phase Angle: 110.7° Of Interest: De Graft crater was named for 20th century Ghanaian playwright, poet, and novelist Joe de Graft following MESSENGER's second flyby of the innermost planet. De Graft is a complex crater that hosts numerous bright hollows on its floor. This image is a mosaic of three NAC images taken as a sequence designed to target the crater. 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. | |
