Canuleia and Sossia Craters

April 25, 2012
This image from NASA's Dawn spacecraft of asteroid Vesta shows two craters, one that has been named Canuleia and one that has been named Sossia.

This Dawn framing camera (FC) image of Vesta shows two craters, one that has been named Canuleia and one that has been named Sossia. Canuleia is the bright crater in the top right of the image and Sossia crater is the smaller crater near the center of the image. Canuleia was the subject of the previous image of the day. Sossia crater is approximately 8 kilometers (5 miles) in diameter and is surrounded by areas of dark material. One area of dark material is associated with the small crater located just off the bottom right part of Sossia's rim and another area of dark material is located along the top left rim. This area of dark material spreads out from the rim in long, curvilinear streaks. There is also some bright material inside of Sossia crater but Canuleia crater contains much more bright material.

This image is located in Vesta's Urbinia quadrangle, in Vesta's southern hemisphere. NASA's Dawn spacecraft obtained this image with its framing camera on Oct. 20, 2011. This image was taken through the camera's clear filter. The distance to the surface of Vesta is 700 kilometers (435 miles) and the image has a resolution of about 64 meters (210 feet) per pixel. This image was acquired during the HAMO (high-altitude mapping orbit) 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.
