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 |

Breakdown of hydrated minerals on the polar side of dark, probably basaltic dunes at temperatures no higher that say 20 celcius for a brief period? What hydrated minerals are you proposing or are you thinking minerals in frozen brines?

What hydrated minerals are you proposing or are you thinking minerals in frozen brines? The only hydrated mineral with that property I know of is meridianiite decomposing in epsomite and water. This should be possible to distinguish from basalt, i.e. confirmed or discarded. |
