5. Dawn What will the Framing Cameras do? They will return images that map the surfaces of Vesta and Ceres. These images will be used to: Measure spin rates of Vesta and Ceres.Create global topography, albedo, and color maps of Vesta and Ceres using clear and narrow band filters. Determine the shape, volume, and mass of Vesta and Ceres. Map the elemental and mineralogical composition of Vesta and Ceres. Study crater morphology and distribution on Vesta and Ceres. Search for fractures and evidence of volcanism.Determine surface reflectance characteristics. 5
