I guess those polar icecaps aren't optical illusions afterall....

Sorry, but if this is the best NASA can do they need a good butt kicking....we've SEEN the caps, we know there is water there.

Not necessarily... those icecaps COULD be dry ice... frozen carbon dioxide.

It's pretty much been agreed that the icecaps are water ice, but the possibility still remained that it was dry ice. Finding liquid water would decide it once and for all.
