NASA's Dawn spacecraft obtained these images of Vesta with its framing camera on Aug. 28 (left) and Sept. 9, 2011. These images of the south polar region were taken through the camera's clear filter at a distance of 1,700 miles (2,740 kilometers). The images have a resolution of about 260 and 130 meters per pixel.

The Dawn mission to Vesta and Ceres is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, Calif., for NASA's Science Mission Directorate, Washington. UCLA is responsible for overall Dawn mission science. The Dawn framing cameras were developed and built under the leadership of the Max Planck Institute for Solar System Research, Katlenburg-Lindau, Germany, with significant contributions by DLR German Aerospace Center, Institute of Planetary Research, Berlin, and in coordination with the Institute of Computer and Communication Network Engineering, Braunschweig. The Framing Camera project is funded by the Max Planck Society, DLR, and NASA/JPL.
