Center Longitude: 253.8 E
Resolution: 167 meters/pixel
Scale: The crater on the right side of the image is about 25 km (15.5 miles) in diameter.
Incidence Angle: 85.0
Emission Angle: 0.4
Phase Angle: 85.4

Of Interest: This scene, which lies near the crater Bjorson in Mercury's northern hemisphere, displays features with a variety of ages and degradation. The crater on the right side of the image is relatively fresh and some terracing, or collapse of the walls after impact, is visible. The crater at the bottom of the image has been embayed and contains younger craters within it, indicating that it is older.

This image was acquired as part of MDIS's high-resolution 3-color imaging campaign. The 3-color campaign is a major mapping activity in MESSENGER's extended mission. It complements the 8-color base map (at an average resolution of 1 km/pixel) acquired during MESSENGER's primary mission by imaging Mercury's surface in a subset of the color filters at the highest resolution possible. The three narrow-band color filters are centered at wavelengths of 430 nm, 750 nm, and 1000 nm, and image resolutions generally range from 100 to 400 meters/pixel in the northern hemisphere.

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, MESSENGER acquired 88,746 images and extensive other data sets. MESSENGER is now in a yearlong extended mission, during which plans call for the acquisition of more than 80,000 additional images to support MESSENGER's science goals.
