Of Interest: The large crater seen here, located in Mercury's northern plains, exhibits signs of extensive flooding by lava. Similar to ghost craters that have been completely covered by volcanic flows, much of Monteverde's northern rim and interior have been flooded and filled in by lava. Only the remains of Monteverdi's southern rim jut above the relatively flat interior of the crater. This crater was named after the Italian composer Claudio Monteverdi (1567-1643), whose music marks the transition from the Renaissance style of music to the Baroque style.

This image was acquired as part of MDIS's minimum-phase-angle color campaign. Near the north polar region, the incidence angle (measured from the vertical) is always fairly high because the Sun is low on the horizon. The minimum-phase-angle color campaign acquires images under conditions that minimize the shadows in an image by viewing the surface as nearly as possible from the same direction as the Sun's illumination, which minimizes the phase angle. Images are acquired through five of the WAC's narrow-band color filters, for regions north of 60 N, at an average resolution of 500 meters/pixel. The minimum-phase-angle color campaign began in March 2013.

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. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
