A Nursery for Hollows?

December 22, 2012
Date acquired: November 19, 2012 Image Mission Elapsed Time (MET): 261771341 Image ID: 2981614 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 10.45° Center Longitude: 113.6° E Resolution: 40 meters/pixel Scale: This image is 42 km (26 mi.) across Incidence Angle: 66.5° Emission Angle: 13.6° Phase Angle: 80.2° Of Interest: In the well-documented case of Eminescu's hollows, the image above provides some new insight. Though the majority of the hollows are located on and directly around the central peak, if you look closely you'll see that there are small hollows located on top of the knobby texture on the upper right side of the image. Are these hollows younger than the ones on Eminescu's central peak and floor? Are hollows currently forming in Eminescu? 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.
