Bright Rays, Small Crater
Release Date: May 31, 2011
Topics: Crater Rays, Named Craters, Terminator Views, WAC



Date acquired: May 26, 2011
Image Mission Elapsed Time (MET): 214856673
Image ID: 298558
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filter: 7 (748 nanometers)
Center Latitude: -71.90
Center Longitude: 230.4 E
Resolution: 1376 meters/pixel
Scale: The distance from the western corner of this image to the eastern corner is about 2,000 kilometers (1,240 miles)

Of Interest: The crater Han Kan, with a diameter of 50 kilometers, is far from the largest crater in this scene, but its bright rays make it stand out from its many larger neighbors. View Mercury in Google Earth to identify Han Kan's neighbors, including the double-ring basins Bach and Cervantes.

This image was acquired as part of MDIS's color base map. The color base map is composed of WAC images taken through eight different narrow-band color filters and will cover more than 90% of Mercury's surface with an average resolution of 1 kilometer/pixel (0.6 miles/pixel). The highest-quality color images are obtained for Mercury's surface when both the spacecraft and the Sun are overhead, so these images typically are taken with viewing conditions of low incidence and emission angles.

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.
