A Fresh Perspective

December 16, 2013
Release Date: December 13, 2013 Topics: Crater Rays, NAC, Named Craters Date acquired: November 13, 2013 Image Mission Elapsed Time (MET): 26657614 Image ID: 5189176 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: -0.24° Center Longitude: 235.3° E Resolution: 37 meters/pixel Scale: Mena crater has a diameter of 15 km (9 miles) Incidence Angle: 54.7° Emission Angle: 23.4° Phase Angle: 71.0° Of Interest: Here we get a closer look at the fresh, bright-rayed crater Mena. Solidified impact melt forms a smooth pond on the western side of the crater floor. This asymmetry is due to the fact that Mena formed on the sloping rim of an older crater, as seen in this wider view. This image was acquired as a targeted set of stereo images. Targeted stereo observations are acquired at resolutions much higher than that of the 200-meter/pixel stereo base map. These targets acquired with the NAC enable the detailed topography of Mercury's surface to be determined for a local area of interest. 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. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
