 Click on image to enlarge. | A Dramatic PeakRelease Date: July 18, 2012 |
Date acquired: July 03, 2012
Image Mission Elapsed Time (MET): 249790754
Image ID: 2129670
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Center Latitude: -21.77°
Center Longitude: 202.6° E
Resolution: 120 meters/pixel
Scale: The crater's diameter is 100km (62 miles).
Incidence Angle: 83.4°
Emission Angle: 59.9°
Phase Angle: 134.5°
Of Interest: The main crater in this image, Eitoku, displays central peaks that appear especially prominent due to the high solar incidence angle and the fact that this image has not been map projected. Central peaks are common in Mercury's larger craters. Smaller craters visible on the crater floor and rim of Eitoku indicate that it is a relatively old 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 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.
