That picture looks like it's been heavily processed -
look at the apparent resolution of the floor of the
crater against that of the ice-patch - the former has
vague blobs but on the latter you can see what look like
melt-refreeze traces around the right hand side. Why
(how?) this difference, I wonder?

It may be out of focus. The crater is 35km across and the spacecraft is
at about 100km from it ? (is it ?). With the focal length of what they
are using parts of the image could be out of focus at times, plus
motion blur. I am sure someone could explain that better.
