Giambologna Crater


This lovely, fresh, complex crater with a crescent-shaped central peak was recently given the name Giambologna by the International Astronomical Union. The Dutch sculptor Jean Boulogne Giambologna (1529-1608) is most famous for his bronze statues of the god Mercury. The inset photograph shows one that resides in the Museo Nazionale del Bargello, Florence, Italy. Giambologna crater is distinctive for its wide, terraced western wall and the very smooth impact melt pond that covers the eastern floor. The wall terracing probably resulted from extensive collapse that happened because Giambologna formed on a slope -- the wall of an older, larger crater.

This image was acquired as part of MDIS's high-resolution stereo imaging campaign. Images from the stereo imaging campaign are used in combination with the surface morphology base map or the albedo base map to create high-resolution stereo views of Mercury's surface, with an average resolution of 200 meters/pixel. Viewing the surface under the same Sun illumination conditions but from two or more viewing angles enables information about the small-scale topography of Mercury's surface to be obtained.
