A new paper argues that HiRISE photos show evidence for recent short-lived surface water flows. Neat pictures on Phil Plait's site (my source for the news).
It would be interesting to learn if there was any MGS coverage of the same area. TTT |

Well, we already have a rover sniffing for organics in retreating scarps. Maybe it will also find ice subliming there and not just minerals with a lot of water of crystallisation. On the other hand the water in the gullies could come from the breakdown of hydrated minerals rather than melting ice.
