This anaglyph from NASA's Dawn spacecraft shows degraded craters shows partially degraded craters and ridges in asteroid Vesta's Pinaria quadrangle. You need 3D glasses to view this image.

This 3-D image, called an anaglyph, shows partially degraded craters and ridges. To create this anaglyph, two differently colored images are superimposed with an offset to create depth. When viewed through red-blue glasses this anaglyph shows a 3-D view of Vesta's surface. The depth effect in this anaglyph, derived from topography differences, was calculated from the shape model of Vesta. Piles of material in the bases of the craters show up clearly in this 3-D image. This material likely slumped down from the sides of the craters. Also, some bright and dark material can be seen cropping out of the rims of the craters and slumping towards their centers. The ridges, which run roughly horizontally across the image, also stand out in the 3-D image.

The images used to generate the anaglyph are located in Vesta's Pinaria quadrangle and the center is 40 degrees south latitude, 29 degrees east longitude. NASA's Dawn spacecraft obtained this image with its framing camera on Jul. 24, 2011. This image was taken through the camera's clear filter. The distance to the surface of Vesta is 5,200 kilometers (3,231 miles) and the image has a resolution of about 485 meters (1591 feet) per pixel. This image was acquired during the approach phase of the mission.

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.
