Crater wall with sinuous features - Nasa Dawn Mission Image of the Day13 Apr 2012

Dawn Mission: News & Events > Crater wall with sinuous features

This Dawn framing camera (FC) image of Vesta shows part of a large crater with a relatively fresh rim. The interior of the crater appears much brighter than the surrounding area because this image has been stretched to brighten the interior of the crater. In the original image, the crater interior was originally much darker than it appears now. The most striking feature in this image is the bright and dark material cropping out near the rim of the crater and slumping towards the crater center. This material is rather sinuous in shape.   


This image is located in Vesta’s Numisia quadrangle, near the equator. NASA’s Dawn spacecraft obtained this image with its framing camera on Dec. 18, 2011. This image was taken through the camera’s clear filter. The distance to the surface of Vesta is 272 kilometers (169 miles) and the image has a resolution of about 25 meters (82 feet) per pixel. This image was acquired during the LAMO (low-altitude mapping orbit) phase of the mission.
