Detail From The New Three-Color Mosaic


A new color mosaic created from MESSENGER images is now available! This mosaic was part of a release on March 7, 2014 by NASA's Planetary Data System (PDS). A portion of the new color mosaic is shown here; can you find the craters Debussy, Derain, Berkel, and Warhol in this view? Explore the full 3-color mosaic (and confirm the locations of these craters) in QuickMap.

The images for MDIS's high-resolution 3-color mosaic were acquired during MESSENGER's second year in orbit about Mercury. The 3-color mosaic was designed to complement the 8-color base map acquired during MESSENGER's primary mission. By imaging Mercury's surface in a subset of the color filters at the highest resolution possible, the 3-color mosaic is available at 332 meters/pixel,as compared to 665 meters/pixel for the 8-color mosaic.
