26.06.2012 - Apparent brightness and topography images of Laelia and Sextilia craters

The left-hand image is a Dawn FC (framing camera) image, which shows the apparent brightness of Vesta’s surface. The right-hand image is based on this apparent brightness image, which has had a color-coded height representation of the topography overlain onto it. The topography is calculated from a set of images that were observed from different viewing directions, which allows stereo reconstruction. The various colors correspond to the height of the area. The white and red areas in the topography image are the highest areas and the blue areas are the lowest areas. Laelia crater is the crater surrounded by dark material offset to the left of the center of the image. Sextilia crater is the large crater in the top of the images with bright material around its rim. In the apparent brightness image it is clear that some of the dark material associated with Laelia crater crops out from its rim and slumps towards its center and that some has been excavated by smaller craters surrounding Laelia. The bowl shape of Sextilia crater is seen in the topography image.
