Geologic mapping of the AV-3 Caparronia quadrangle of asteroid 4 Vesta

NASA’s Dawn spacecraft began orbiting the inner main belt asteroid 4 Vesta on July 16, 2011, and will characterize the geology, elemental and mineralogical composition, topography, and internal structure of Vesta before departing for asteroid 1 Ceres in late 2012. As part of the Dawn data analysis, the science team is constructing geological mapping of the surface, in the form of 15 quadrangle maps. This abstract reports preliminary results from mapping of quadrangle Av-3, named for Caparronia crater.
