Image ID: 2135748
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filter: 7 (748 nanometers)
Center Latitude: 35.98
Center Longitude: 70.56 E

Scale: Copland crater is 209 km (130 miles) in diameter
Incidence Angle: 55.8
Emission Angle: 26.7
Phase Angle: 82.6

Of Interest: This image, taken with the Wide Angle Camera (WAC), shows a portion of Copland crater and its ejecta blanket. Copland crater is flooded with volcanic material, giving it a smooth appearance. The crater was named for Aaron Copland, the 20th century American composer and conductor whose ballet score Appalachian Spring popularized the Shaker melody Simple Gifts.

This image was acquired as part of MDIS's high-resolution albedo base map. The best images for discerning variations in albedo, or brightness, on the surface are acquired when the Sun is overhead, so these images typically are taken with low incidence angles. The albedo base map is a major mapping campaign in MESSENGER's extended mission and will cover Mercury's surface at an average resolution of 200 meters/pixel.

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.
