Actually, now that I see it, you're right. I just was not expecting that sub-surface. I was expecting more sand.

The navcam pans are really nice! I hope it is OK for Ant103 - I did go over his anaglyph and made it a bit brighter (of course this kills the mood a bit): Are we looking approx. North? I think I can see the northern inlet channel, in the crater wall - in the center of the anaglyph! If so - that is sharp and bright! http://www.unmannedspaceflight.com/index.p...st&id=28432 And I was ( once again ) poorly oriented. News Conference Starting |

8gs! I guess Phoenix's poor performance during sample drop off really put them off at the time! (Drop that load properly you lousy piece of hardware! )

[attachment=28429:NLxRA_40...46M_crop.jpg] Stomp! great cross eyed image The slight slumping and cracking around the wheel marks seem to imply some sort of lightly cemented crust. So these little drifts are probably not active. ( I see that this has been discussed. But could all these drifts the mers and curiosity have treaded be inactive because they are crusted?) |

Animation of arm movement between 1 pm and 3 pm local time:
click to enlarge the animation begins with the APXS measurement at 1 pm. The instrument changes to MAHLI followed by undisturbed and wheel disturbed soil region images respectively.

To me it looks exactly like flour. Completely dry, yet cohesive -- that's the nature of very fine-grained material.

Exacly like fine flour, cornflour, talc, exceptionally fine grained dry material.

Undisturbed soil image: So do those little clumps break up into powder under pressure? Or are they solid but get pushed under the fine powder as the wheel moves over them? -------------------- |

Seeing MAHLI's images of the scuffed ripple's interior, a question popped in my head; is the chemical makeup of sand drifts all over Mars generally homogenous or are they extremely different globally as dirt that make them up don't get to move around very much like the lighter, easily transported dust?
It's just that Serpent from Spirit's days in 2004 keeps coming up whenever I see Rocknest (man I miss the old gal!) -------------------- |

Horizon flattened animated anaglyph GIF of the Sol 58 arm and turret manuevers from hazcam. I left it pretty large (1300x939 pixels, 4MB) so it may not begin to animate till fully downloaded, but I think the large size is worth the wait...
... and for anyone so inclined, here's the even larger 1800 pixel wide Full Resolution Version (7MB) -------------------- "We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time." -T.S. Eliot
