March Madness
Release Date: June 13, 2011
Topics: ,

Date acquired: May 04, 2011
Image Mission Elapsed Time (MET): 213023953
Image ID: 212563
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Center Latitude: 30.96°
Center Longitude: 183.9° E
Resolution: 116 meters/pixel
Scale: March crater is about 68 km (42 miles) across
Incidence Angle: 71.1°
Emission Angle: 36.4°
Phase Angle: 107.5°

Of Interest:This image, taken with the Narrow Angle Camera (NAC), shows March crater, named for the 15th century Valencian poet Ausiās March. The faint striations across the wall terraces in the lower right portion of the image may have been caused by landsliding or by emplacement of ejecta from another impact outside the field of view.

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.
