Mercury in Color

During MESSENGER's second flyby of Mercury, MDIS acquired a strip of high-resolution images obtained with each of the WAC's 11 different color filters. The graphic shown here displays the resulting enhanced-color mosaic and gives considerable detail about the images, how the mosaic was created, and the geologic features that can be seen.

Currently, these images are the highest-resolution color images ever obtained of the Solar System's innermost planet, but not for long! On March 18, 2011, MESSENGER will enter into orbit about Mercury, and the mission's extensive, year-long science observation campaign will begin. That campaign includes capturing color images of Mercury's surface at higher resolution than ever before.

Special thanks to Kathryn Powell, a summer intern student with the MESSENGER project, for contributing to the content of this graphic. Note: since the original creation of this graphic, the crater identified in the upper right with the label "young rayed crater" has been named Dominici. See PIA12871 to learn more about this recently named crater.

Mercury Landscape

When MESSENGER first flew by Mercury on January 14, 2008, MDIS acquired images of a large portion of Mercury's surface that had never previously been seen by spacecraft. This mosaic of NAC images shows some of the geologic features discovered during that first flyby that have been subsequently named: the curving cliff face of Beagle Rupes, the elongated crater Sveinsdottir, and the craters Izquierdo and Kunisada flooded with lava.

This year, the MESSENGER spacecraft is positioned once again to visit the Solar System's innermost planet. However, this time, the spacecraft won't just pass by. On March 18, 2011, a 15-minute maneuver will place MESSENGER in orbit about Mercury, making it the first spacecraft ever to do so. The MESSENGER mission will then begin an extensive year-long science campaign to unravel Mercury's mysteries. 2011 promises to be an exciting year of further discoveries for the MESSENGER mission.
