The shadowy outlines of the terrain in Vesta's northern region are visible in this image from NASA's Dawn spacecraft. The image comes from the last sequence of images Dawn obtained of the giant asteroid Vesta as it departed the giant asteroid. The view looks down at Vesta's north pole, which is in the middle of the image. When Dawn arrived in July 2011, Vesta's north pole was in darkness. After more than a year at Vesta, the sunlight has now made it to Vesta's north pole.
This image was taken by Dawn's framing camera on Aug. 25, 2012 PDT (Aug. 26, 2012 CET). Dawn escaped from Vesta's orbit on Sept. 4, 2012 PDT (Sept. 5, 2012 CET).
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. The Dawn framing cameras have been 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.
