DAWN - Bild des Tages - Oktober 2011  19.10.2011 - Ejecta
blanket  These Dawn FC (framing camera) images show two
different resolution views of the ejecta blanket of Vesta’s
“snowman craters”. The snowman-like pattern of these craters is
clearly seen in the center of the left hand image. However, the
ejecta blanket surrounding these craters is much less obvious in
the lower resolution, left hand image. The ejecta blanket is
much clearer in the higher resolution right hand image: it is
visible as an area of Vesta’s surface which is significantly
smoother than the neighboring regions. The ejecta blanket thins
towards the top left of this image and consequently Vesta’s
surface begins to appear rougher. Some older impacts are seen
through the ejecta blanket and the clusters of small, fresh
craters on the ejecta blanket are likely secondary impacts.
These secondary craters probably formed due to large debris
being thrown out of the “snowmen craters” during their
formation. The smaller debris which were thrown out
