In the last few years, the Red Planet has yielded up many new clues that life may have once existed there...and may even exist there today. We now have proof that water once flowed on the surface, that Mars once had lakes, and that the frozen poles are mostly water, not carbon dioxide as previously thought. Mars has snow - an aurora - and lightning generated by dust storms. Most intriguing of all, though, are the seasonal plumes of methane that just may point to bacteria living below the surface.
