Mena and Cezanne Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)
|
In this Image-Mosaic, the Bright Rays of Mena Crater and the distinctive color difference of Cezanne Crater (with the surrounding area) are well highlighted. These two distinctive Impact Features provide beautiful contrast to this Absolute Natural Color image, giving the viewer more insight into reflectance variations (---> Albedoes) on Mercury's Surface. Also note the extremely old, degraded and larger, infilled Unnamed Crater visible on the center right of the frame, which is crossed by at least three major Crater Chains.
Date acquired: June 04, 2012
Image Mission Elapsed Time (MET): 247336883, 247336875, 247336879
Image ID: 1955368, 1955366, 1955367
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: 3,78° South
Center Longitude: 235,8° East
Resolution: 552 meters/pixel
Scale: Cezanne Crater, such as the Crater in the bottom center, is about 67 km (approx. 41 miles) in diameter.
Solar Incidence Angle: 55,6° (meaning that the Sun was about 34,4° above the imaged Local Horizon at the time the pictures were taken)
Emission Angle: 0,0° (meaning that the MESSENGER Spacecraft, at the time that the pictures were taken, was absolutely perpendicular to the Mercurian Surface visible in the center of the frame)
Sun-Mercury-MESSENGER (or "Phase") Angle: 55,6°
