Impact art

This image shows a small portion of the ejecta blanket of an unnamed fresh impact crater (1 km diameter) located on the southeastern wall of crater Darwin C (15 km diameter, over 2500 m deep!). The linear reflectance boundary that runs diagonally from lower left to upper right is a break in slope between the steep wall (lower right) and floor (upper left) of Darwin C crater; to the left of that line the floor is essentially flat. Exposure to space weathering tends to lower the brightness of surface materials on an airless body like the Moon. But compositional differences also affect the reflectance of surface materials.
