Misleading
Sorry, Robert, but your suggestion that Mars is "actually wetter than Antarctica at some times" was deliberately misleading - a confuscation of the main point that starts this thread - an attempt on your part to change the subject from the point being made by the article I posted.
The bottom line is that the surface of Mars is incredibly dry. And, we've yet to find a single drop of liquid water on the surface of Mars.
And your reply post here attempts to continue the confusion by asserting that "Mars is warmer than some locations on Earth." What gets deliberately lost in that remark is the very different character of surface temperature on Mars than that on earth. Its a gross generalization that intends to hide whats really happening.
