Submission + - Martian Gullies Explained By Flow of Sand (technologyreview.com)

eldavojohn writes: There's a lot of evidence that a very long time ago some fluid once flowed on Mars but the primary evidence of water today — gullies inside craters — is explainable by a much less exotic reason: flowing dust and sand. It would now seem that the news from 2006 that NASA had found definitive evidence of flowing water on today's Mars needs to be comprehensively reexamined. The Bad Astronomer lays claim that flowing sand and dust doesn't explain all recent hi-res imagery from the red planet but it certainly does seem more plausible considering what we know about Mars.
