I would add however Stu that the age of dunes on this steep slope doesn't necessarily correspond to the age of dunes on the plains of Meridiani. So don't abandon your idea yet. For all we know these dunes migrate down that slope on a much more frequent basis. And if the composition is different from what we've seen previously then the mechanical properties of the particles comprising them will be different too. Show me this same photo two years hence and then we can come to some conclusions.

teleconference was about water on the moon! Solar wind trapped in lunar soil:hydrogen ions combining with oxygen in the soil to form hydroxyl and water molecules...higher concentration at the higher latitudes towards the poles...diurnal variations with higher concentrations in the morning and dusk!

That was the lunar press conference.
Right NOW - there is a teleconference about MRO - http://www.nasa.gov/news/media/newsaudio/index.html http://www.nasa.gov/mission_pages/MRO/news/mro20090924.html They have spotted ice in fresh craters. Not 1% ice in Moon soil. 99% ice in mars soil  Would you like some ice with your lunar regolith? How about some martian regolith with your ice. |

As with Dr. Johnson's dancing dog, the wonder is not that there's great ice on the moon -- the wonder is that it's there at all.
However, I'll admit Martian ice in fresh craters is pretty cool too. --Greg |

THAT is an incredible image, Stu; thank you!!!

The latest batch of releases also features a rather good image of some of the "martian spiders" - sorry, "radial channels"
 ... couple of colourised crops here...http://twitpic.com/jtjdy/full http://twitpic.com/jtjf8/full -------------------- |

Subtiler, but DDs can do beautiful artwork too. It's fascinating to see how the DDs spun around. Cropped and sharpened image: 2.7MB full res. http://www.greuti.ch/mro/ESP_014426_2070.jpg 0.65MB http://www.greuti.ch/mro/ESP_014426_2070s.jpg -------------------- |

I love the combination of slope streaks and dustdevil tracks! It's a smoking gun of sorts.
