Date acquired: April 07, 2012
Image Mission Elapsed Time (MET): 242296379, 242338160, 242338176, 242338192, 242379971
Image ID: 1617565, 1619567, 1619568, 1619569, 1621694
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Center Latitude: 37.1°
Center Longitude: 232.7° E
Resolution: 32.5 meters/pixel
Scale: Degas is approximately 53 km (33 mi.) in diameter.
Incidence Angle: 68.5°
Emission Angle: 15.6°
Phase Angle: 52.8°
Of Interest: Degas crater is shown here in spectacular detail. This high-resolution mosaic is made up of five separate images. The floor of the crater contains cracks that formed as the melt sheet cooled and contracted. Downslope movement of material on the central peaks and walls has exposed fresh, bright material.
This mosaic is made up of images acquired as high-resolution targeted observations. 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.
