Mercury's surface is riven by large tectonic structures that formed when the planet's interior cooled and contracted. One of the most notable such structures is Enterprise Rupes, a lobate scarp system 822 km (510 mi.) in length. Enterprise Rupes cross-cuts the majestic Rembrandt impact basin, some 716 km (445 mi.) across. Rembrandt itself hosts numerous examples where lobate scarps cross smaller craters, such as that shown here. The scarp in this scene lies close to the perimeter of Rembrandt and parallels the basin's outline, before crossing Enterprise Rupes itself farther to the north.
This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

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.
