*This doesn't have anything to do with the rovers, so I'm creating a different thread for it. This is spectacular:
"The tilted planet causes ice on one side of a crack to heat and vaporize, deepening and widening the crack. Then the water vapor hits the shady, colder side of the growing canyon and refreezes.
Eventually, chasms more than a half-mile (1 kilometer) deep developed, and they cover hundreds of miles of the polar regions. But only on Mars, it seems.
Characteristics unique to the red planet -- its thin atmosphere, chilly climate and specific planetary tilt -- make it the only known place in the solar system where the ice spirals occur."
*Be sure to check out the "simulation generated patterns" image towards the bottom of the article. It reminds me of Celtic knotwork.
