Once upon a time - roughly four billion years ago - Mars was warm and wet, much like Earth. Liquid water flowed on the Martian surface in long rivers that emptied into shallow seas. A thick atmosphere blanketed the planet and kept it warm. Living microbes might have even arisen, some scientists believe, starting Mars down the path toward becoming a second life-filled planet next door to our own. http://www.physorg.com/news177179617.html Space & Earth Wed, 11 Nov 2009 16:34:12 EST news177179617 (PhysOrg.com) -- NASA's Mars rover Spirit, lodged in Martian soil that is causing traction trouble, is taking advantage of the situation by learning more about the Red Planet's environmental history. http://www.physorg.com/news165164322.html Space & Earth Thu, 25 Jun 2009 16:30:01 EST news165164322 (PhysOrg.com) -- In a race against time and the elements, engineers with NASA's Phoenix Mars Lander mission hope to extend the lander's survival by gradually shutting down some of its instruments and heaters, starting today. http://www.physorg.com/news144511029.html Space & Earth Wed, 29 Oct 2008 14:57:09 EST news144511029 Scientists are analyzing results from soil samples delivered several weeks ago to science instruments on NASA's Phoenix Mars Lander to understand the landing site's soil chemistry and mineralogy. http://www.physorg.com/news137128096.html Space & Earth Tue, 05 Aug 2008 04:08:16 EST news137128096
