Of Interest: Like Friday's image, today we see Mercury's surface at an image resolution we have rarely come close to before. In this scene, a portion of the rim of an unnamed crater 17 km (11 mi.) in diameter is visible, atop which sits a smaller, later crater (lower center). The prolonged record of impact cratering on Mercury is one of the planet's most visible traits, yet we continue to see the results of that process with ever higher-resolution images. And so, even at resolutions of 9 meters (~30 feet) per pixel, we observe small primary and secondary craters peppering the surface of the innermost planet.
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.
