| Date acquired: July 28, 2011 Image Mission Elapsed Time (MET): 220329477 Image ID: 560706 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 35.11° Center Longitude: 35.70° E Resolution: 85 meters/pixel Scale: This crater is approximately 65 km (40 miles) in diameter Incidence Angle: 56.5° Emission Angle: 58.1° Phase Angle: 102.0° Of Interest: This beautiful oblique view of a fresh impact crater was captured as the MESSENGER spacecraft slewed to the side to get a better look. The primary purpose for this slew was actually so that the Mercury Atmospheric and Surface Composition Spectrometer (MASCS) instrument could collect a reflectance spectrum of the crater's ejecta. 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. The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet.

During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals. | |
