Can you see which of the photo's below is from Earth and which from Mars?
UPDATE: Well, it was stupid of me of course to suggest these things were snow, because we are looking at IR-images here. But now I'm looking at the same spot taken with IR by night and the "lichen" turn up completely black!(see below) This means they are not radiating any IR. What this means exactly, I have to find out.
