Today's astronomy picture of the day is a view of the rim of Victoria Crater, taken by the Opportunity rover as it descends into the crater. And I could swear that I'm looking at one of the big eolian sandstones from the Colorado Plateau. Moab on Mars?
I guess it isn't a major finding, seeing evidence for wind-blown sediment on Mars. But it's amazing to see sedimentary structures from another planet. And eolian sandstones are beautiful.
