DescriptionHomer and Dominici craters on Mercury.png |
English: Date acquired: September 03, 2011
Image Mission Elapsed Time (MET): 223573004, 223573008, 223573012 Image ID: 714331, 714332, 714333 Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) WAC filter: 9 (1000 nanometers), 7 (750 nanometers), 6 (433 nanometers) as red-green-blue Center Latitude: -1.38° Center Longitude: 323.5° E Resolution: 338 meters/pixel Scale: Dominici crater is approximately 20 km (12 mi.) in diameter. Incidence Angle: 36.1° Emission Angle: 36.6° Phase Angle: 71.8° Of Interest: Dominici crater, the very bright crater to the top of this image, exhibits bright rays and contains hollows. This crater lies upon the peak ring of Homer Basin, a very degraded peak ring basin that has been filled by volcanism. This image contains several examples of craters that have excavated materials from depth that are spectrally distinct from the surface volcanic layers, providing windows into the subsurface. MESSENGER scientists are estimating the approximate depths of these spectrally distinct materials by applying knowledge of how impacts excavate material during the cratering process. The 1000, 750, and 430 nm bands of the Wide Angle Camera are displayed in red, green, and blue, respectively. 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. |
