Basins Everywhere
Release Date: May 18, 2011
Topics: WAC



Date acquired: May 14, 2011
Image Mission Elapsed Time (MET): 213850584
Image ID: 251424
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filter: 7 (748 nanometers)
Center Latitude: 66.10
Center Longitude: 167.2 E
Resolution: 207 meters/pixel
Scale: The basin in this image is approximately 250 km (155 miles) across
Incidence Angle: 76.2
Emission Angle: 57.8
Phase Angle: 134.1

Of Interest: An unnamed basin, largely filled with smooth plains, occupies most of this WAC image. The oblique look at this basin highlights the more rugged and cratered terrain exterior to the basin.

This image was acquired as part of MDIS's high-resolution surface morphology base map. The surface morphology base map will cover more than 90% of Mercury's surface with an average resolution of 250 meters/pixel (0.16 miles/pixel or 820 feet/pixel). Images acquired for the surface morphology base map typically have off-vertical Sun angles (i.e., high incidence angles) and visible shadows so as to reveal clearly the topographic form of geologic features.

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.
