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?
