Publisher: Hoffman/Nick, 2001; Star Date, 2001ISSN: 1522-3264;.Subject(s): Carbon dioxide | Mars (Planet) -- Climate | Mars (Planet) -- Geology | Mars (Planet) -- Surface | Mars (Planet) -- WaterDDC classification: 050 Summary: "White Mars" -- "Because life on Earth requires water, humanity's search for life has become a search for water. For this reason, NASA is targeting Europa, a moon of Jupiter that may have liquid water ocean beneath its thick, icy crust. But NASA also has Mars in its crosshairs. On Mars, huge erosional channels suggest that liquids, perhaps water, flowed across the surface in the distant past. Many scientists believe that rivers and lakes of water, and perhaps even oceans, once existed on Mars. NASA has designed missions specifically to reveal these features. But this search may be ill-founded. Despite intense research, the evidence for water on Mars is flimsier than recent reports would have us believe." (MERCURY) This article examines a theory called "White Mars", which contends that physical evidence of water on Mars is actually created by the flow of liquid carbon dioxide and rocks instead of water.Summary: "Watery Evidence" -- "Signs of a warm, wet past cover Mars almost from pole to pole. channels that resemble dry riverbeds crisscross the planet, and deep layers of sediment and jumbled rocks look a dripping faucet by comparison. There's evidence of a large, shallow ocean in the nothern hemisphere, and hints that layer upon layer of soil accumulated at the bottoms of ancient lakes. It's as if someone simply turned off the tap and mars suddenly, inexplicably may have coursed over the surface of mars at some point in history."
