Seeing to New Depths

April 17, 2013
Release Date: April 12, 2013 Topics: Hollows, NAC Date acquired: March 22, 2013 Image Mission Elapsed Time (MET) (since January 8, 2013): 6291928, 6292156 Image ID: 3741269, 3741270 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 25.11° Center Longitude: 266.4° E Resolution: 36 meters/pixel Scale: The diameter of this crater is 31 kilometers (19 miles) Incidence Angle: 44.7°, 44.8° Emission Angle: 40.5°, 35.5° Phase Angle: 72.9°, 78.1° Of Interest: As promised in yesterday's featured image, here is another 3D anaglyph that was created from recently acquired images. View it with a pair of red-cyan 3D glasses to get the full effect and to see deep into this crater! The topography appears exaggerated in the stereo view of this roughly one-kilometer deep crater, accentuating the terraces on the crater's walls and the central peak, topped with hollows, rising from the crater's floor. This image has been rotated 90° to the right (such that north is to the right) for better viewing with the red-cyan glasses. This image was created from 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.
