Abedin Crater Wall


The beautiful Abedin crater is featured in today's image. The crater's sunlit wall meets the crater floor, which occupies the left side of the scene. The floor is largely covered with rock that was melted by the Abdedin impact, ponded on the crater floor, and has now solidified, cracking as it cooled.

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 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high

Graben in Abedin Crater


In this image, a portion of the 116 km- (73 mile-) diameter Abedin Crater is visible. The floor of the crater is generally smooth, and hosts many small troughs that are interpreted to be graben. Graben form as the result of extensional (i.e. pull-apart) stresses, which in this case may have resulted from the cooling and solidification of either impact melt or volcanic fill inside Abedin, similar to that seen in other basins across Mercury.
