Curiosity has put more than 400 meters on the odometer and tosol (sol 56) she bumped up to a sand drift that we now know (via Twitter) is named Rocknest and will be the site of the first sample grab. In last week's press briefing, John Grotzinger warned that we will be here for "what seems like a very long time," 2-3 weeks. They will have to run several samples through the SA-SPaH (Sample Acquisition, Processing and Handling subsystem, pronounced "Saw-spa") and in particular CHIMRA (Collection and Handling for In situ Martian Rock Analysis, pronounced "chimera") in order to "clean" it of any remaining Earthly contamination with good Mars dirt before they deliver the first sample to SAM or Chemin. So this seems like a good place to start a new thread.

As usual, discuss stuff that happened through sol 56 in the previous thread.

Actually, this says a lot about the plasticity of the surface at Glenelg.

Oops no it doesn't. That's a tire....not a print. But what are the fibers?

Just looking at the images as an amateur I would suppose that there is coarser material on top of much finer material. And no - its not a tire smile.gif and the "fibers" are just cracks or fractions in the "sand".

I can recall that the martian soil is acting like a wet sand, but it's actually very dry. The consequence of a material named "maghemite" (imagine a magnet, but in powder, it's pretty much like that). At the surface of this dune, there is a crust, where the sand particles have got some cohesion because of the alternance of wetting and drying. So then, when you walk on it, its like you're walking on snow, with a surface which became hard due to sunlight. And under, you have some wet-but-yet-dry soil.
I hope I was clear unsure.gif

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):

Oh no, that's not a problem. But yes, with jpeg compression and brightening, the stereoscopic effect is reduced.

PS : Panos updated.

Thar being the case, isn't the'surface" pretty unexpected?

To me, it looks very similar to what was seen when the MERs drove into ripples. A slightly crusty surface is expected.

Look identical to similar exercises at Gusev and Meridiani.
