This Image Is Cool!

Release Date: March 13, 2013 Topics: Craters with Bright Material, Hollows, NAC Date acquired: March 06, 2013 Image Mission Elapsed Time (MET): 4881055 Image ID: 3640892 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 25.60° Center Longitude: 356.2° E Resolution: 30 meters/pixel Scale: This crater is approximately 42 km (26 mi.) in diameter. Incidence Angle: 26.6° Emission Angle: 52.9° Phase Angle: 78.2° Of Interest: This stunning view shows a host of hollows along the rim and floor of a 42-km-diameter (26-mi-diameter) crater. The hollow-covered rim to the right in this image is shared between this younger, smaller crater and an older, 120-km-diameter (75-mi.-diameter) crater, inside of which the smaller crater formed. The sun was high in the sky when this image was taken, making the bright hollows easy to see. North is to the right. 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. 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. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MESSENGER acquired 88,746 images and extensive other data sets. MESSENGER is now in a yearlong extended mission, during which plans call for the acquisition of more than 80,000 additional images to support MESSENGER's science goals.
