Date acquired: February 04, 2012
Image Mission Elapsed Time (MET): 236872479
Image ID: 1353311
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Center Latitude: 19.43°
Center Longitude: 81.37° E
Resolution: 22 meters/pixel
Scale: The edges of this image are approximately 23 km (14 miles) long
Incidence Angle: 50.4°
Emission Angle: 9.3°
Phase Angle: 41.1°
Of Interest: This impact crater, approximately 25 km (16 miles) in diameter, has been heavily modified by landslides. Portions of the crater's walls detached and slumped towards the floor, producing terraces along the wall, landslide deposits on the crater floor, and modifying the crater's outline from circular to irregular. The small bright spots on the landslide deposits (near the top of the image) may be hollows, similar to those seen in other impact craters on Mercury.
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. 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, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
