DescriptionAmaral crater.png |
English: Date Acquired: January 14, 2008
Image Mission Elapsed Time (MET): 108829116 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Resolution: 600 meters/pixel (0.37 miles/pixel) Scale: Amaral crater has a diameter of 106 kilometers (66 miles) Spacecraft Altitude: 24,100 kilometers (15,000 miles) Of Interest: Near the top center of this image is the crater Amaral, recently named for the Brazilian modernist painter Tarsila do Amaral, who lived from 1886 to 1973. Amaral crater, with its smooth floor, surrounding ejecta, and small secondary craters, appears noticeably younger than the heavily cratered surface around it. Along with a smooth crater floor, Amaral also has a central peak. Bright material on this peak is of particular interest to members of the MESSENGER Science Team, as it appears to have an unusual color in images acquired in the 11 color filters of the Wide Angle Camera (WAC). In this previously released enhanced color image of Mercury, the central peak of Amaral (just below center left) appears as a bright blue color in striking contrast to the otherwise orange tones of surface material nearby. The different color of the central peak likely indicates rocks with different chemical composition from those on the neighboring surface.
