Astronomy Picture of the Day -- White Rock Fingers on Mars
NASA ^ | October 30, 2011 | (see photo credit)

Posted on 10/30/2011 5:54:42 PM PDT by SunkenCiv

Explanation: What caused this unusual light rock formation on Mars? Intrigued by the possibility that they could be salt deposits left over as an ancient lakebed dried-up, detailed studies of these fingers now indicate a more mundane possibility: volcanic ash. Studying the exact color of the formation indicated the possible volcanic origin. The light material appears to have eroded away from surrounding area, indicating a very low-density substance. The stark contrast between the rocks and the surrounding sand is compounded by the unusual darkness of the sand. The above picture was taken with the Thermal Emission Imaging System on the Mars Odyssey spacecraft currently orbiting Mars. The image spans about 10 kilometers inside a larger crater.

I'm assuming that's an overhead shot, in which case I'd think there are (or were) some powerful winds up there.

Bradbury's sand ships may have been more right on than what we gave him credit.

WTH, Bobby? Trashing your thread before any else of us have the chance?

That could pass as a ‘twinkles up’ by OWS protesters out east.

Well, yeah. 4 1 thing, I figured Helen’s visage would somehow get mentioned.

Just be glad this topic isn’t about Uranus.

Big, big foot?

Fossilized prints of the Id Monster.

It followed the few surviving Krll that fled aboard a starship from Altair IV to Mars.

We know that ancient ship a "Phobos".

If we're not careful, one of our Rovers will awaken it.

Happy Halloween.

Thanks for confiming. See Post #24

(Also, in 24 “krll” = Krell)
