One minor point- the temperature on Mars makes gigantic wide swings. It can get to be pretty warm there. I believe the record high is 81 degrees F, which is what it is this afternoon in Los Angeles. Of course, it also gets down to -200 F, so the swings can be huge.
Temps above freezing have been reported by Curiosity, which is interesting in itself.
