These Dawn FC (framing camera) images show part of the south polar basin. A large scarp (e.g. cliff) is visible in the top right of the images, grooves and hummocky (e.g. wavy/undulating) terrane are visible in the center of the images and the mountain/ central complex is visible in the bottom left of the images. The left image is an albedo image, which is taken directly through the clear filter of the FC. Such an image shows the albedo (e.g. brightness/darkness) of the surface. The right image uses the same albedo image as its base but then a color-coded height representation of the topography is overlain onto it. The various colors correspond to the height of the area that they color. For example, the white in the top left of the right image is the highest area and the blue areas in the bottom right of the image are the lowest. The scarp and surrounding area are some of the highest regions in the image. Then there is a blue colored depression in between this area and the mountain/ central complex. This is a green color which corresponds to a height in between that of the scarp area and the depression area. The topography is calculated from a set of images that were observed from different viewing directions, these are called stereo images.
NASA's Dawn spacecraft obtained the albedo image with its framing camera on August 11th 2011. This image was taken through the camera's clear filter. The distance to the surface of Vesta is 2740 km the image has a resolution of about 250 meters per pixel. The images are projected using a lambert-azimuthal map projection.
The Dawn mission to Vesta and Ceres is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, for NASA's Science Mission Directorate, Washington D.C.. UCLA is responsible for overall Dawn mission science. Dawn's VIR was provided by ASI, the Italian Space Agency and is managed by INAF, Italy's National Institute for Astrophysics, in collaboration with Selex Galileo, where it was built.
