10.10.2011 - Anaglyph image of a large scarp in Vesta’s south polar region

This anaglyph image shows the topography of Vesta’s south polar region. When viewed correctly this image shows a 3D view of Vesta’s surface. This effect was achieved by superimposing two differently colored images with an offset to create depth. To view this image in 3D use red-green, or red-blue, glasses (left eye: red; right eye: green/ blue). The depth effect/ topography differences in this image were calculated from the shape model of Vesta. The dominant feature in this image is the large scarp on the left hand side. This is a piece of the scarp that partially surrounds the south polar depression on Vesta. There are dark marks, which initially look like dark material, cropping out of this scarp in the bottom of the image. But in images with different illuminations it becomes clear that these dark marks are actually shadows from spur features in the scarp. The material at the base of the scarp (right side) is probably due to landsliding. The edge of the south polar mountain/ central complex can be seen in the right side of the image. The framing camera (FC) instrument aboard NASA’s Dawn spacecraft obtained the images used to make this anaglyph on 17th and 20th August 2011. The distance from Dawn to the surface of Vesta was 2740km at this time. The image has a resolution of about 260 meters per pixel.
