Despite Clay Minerals, Early Mars Might Have Been Dry

astroengine writes "Early Mars may not have been as warm or wet as scientists suspect, a finding which could impact the likelihood that the Red Planet was capable of evolving life at the time when it was getting started on Earth. A new study presents an alternative explanation for the prevalence of Mars' ancient clay minerals, which on Earth most often result from water chemically reacting with rock over long periods of time. The process is believed to be a starting point for life."

You can argue minerals all you want but it doesn't change the fact Mars has massive water features. Also they keep finding signs of sedimentary rock. Even some of the first rover pictures have shown it. Taking the evidence as a whole there shouldn't still be a debate about water on Mars. It's a waste of energy and resources. They should be focused on what happened to it? Was most of it lost to space or is it trapped deep in the soil?
