Lecture 26: The Deserts of Mars
For many, the most likely place in the Solar System to search for life\nbeyond the Earth is Mars. This lecture describes the properties of\nMars, a desert world with a thin, dry, cold carbon dioxide atmosphere.\nI will review evidence that has begun to point unequivocally to the\nconclusion that Mars had flowing and standing liquid water on its\nsurface in the past, perhaps during the first billion years or so. \nIf Mars had a warm, wet past, did life also get a start there?\nRecorded live on 2009 Oct 30 in Room 1005 Smith Laboratory on the\nColumbus campus of The Ohio State University.
