Munch Crater


This image is a portion of the MDIS global mosaic basemap that was acquired during MESSENGER's first year in orbit. The scene shows a dramatic close-up of Munch crater, named for the Norwegian impressionist painter, printmaker, and draftsman Edvard Munch (1863-1944). On Wednesday, May 2nd 2012, one of four versions of Munch's famous 1895 pastel The Scream sold at auction for $119.9 million, becoming one of the most expensive pieces of artwork in the world.

Munch crater is situated within the Caloris basin, the youngest large impact basin on Mercury. The floor of Caloris has been flooded with volcanic flows. The ejecta blanket surrounding Munch contains dark material that originated at depth and was excavated by the Munch-forming impact. This dark material may correspond to rock types -- termed lithologies -- that are mineralogically distinct from those we see on the surface.
