MESSENGER: MErcury Surface, Space ENvironment, GEochemistry, and Ranging
| Date acquired: March 29, 2012 Image Mission Elapsed Time (MET): 241545232 Image ID: 1580685 Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) WAC filter: 7 (748 nanometers) Center Latitude: 82.99° Center Longitude: 314.2° E Resolution: 67 meters/pixel Scale: The upper crater is approximately 25 km (15.5 mi.) in diameter. Incidence Angle: 83.0° Emission Angle: 28.3° Phase Angle: 83.7° Of Interest: The two large craters in this scene are located in Goethe basin, a 383-km-diameter basin in the northern plains of Mercury. Portions of these craters are in areas of permanent shadow and host radar-bright materials. 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. | |
