This high-resolution view shows a small, fresh 15-km-diameter impact crater (inset) at a high northern latitude on Mercury. Bright material is exposed on the upper part of the south-facing wall, and hollows are present on a section of the wall that has slumped partway down toward the floor.

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. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
