This Just In . . . Mars Is Cold And Dry

That's what this article basically says.

If you drill deeper into the article, though, you realize that the presence of large deposits of olivine on the surface of Mars only indicates the lack of recent liquid water. Since Mars' atmospheric pressure is only 0.06 bars, there shouldn't be any appreciable liquid water on the surface anyway.

I am more curious about the search for subsurface water, preferably close enough to the surface that settlers can drill for water without too much effort. Certainly other reports from Mars indicate the possibility of water close to the surface, if not on it.

With NASA's Spirit and Opportunity rovers, the ESA's Mars Express, and the Japanese Nozomi all due to arrive next year, I am looking forward to a "flood" of new data.
