A long scarp runs vertically through the center of this image, deforming pre-existing craters along its length. At the bottom of this image, the scarp cuts through the wall and floor of the crater Ts'ai Wen-Chi (124 km diameter), named for the Han Dynasty poet and composer.

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.
