Image Mission Elapsed Time (MET): 228589200, 228589220, 228589204 Image ID: 956051, 956056, 956052 Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) WAC filters: 9, 7, 6 (996, 748, 433 nanometers) in red, green, and blue Center Latitude: -37.80° Center Longitude: 303.8° E Resolution: 655 meters/pixel Scale: Scene is approximately 700 km (435 miles) across Incidence Angle: 71.1° Emission Angle: 15.9° Phase Angle: 86.8°

Of Interest: Two prominent basins, Chekhov at the upper left and Schubert at lower right, are both just under 200 km in diameter but have very different appearances. Chekhov has a prominent peak ring and its older age is reflected in the numerous craters that have battered its rim and floor. Schubert's floor is smooth with only a hint of its peak ring peeking through.

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 250-meter/pixel (820 feet/pixel) morphology base map or the 1-kilometer/pixel (0.6 miles/pixel) color base map. It is not possible to cover all of Mercury's surface at this high resolution during MESSENGER's one-year mission, but several areas of high scientific interest are generally imaged in this mode each week.
