Looks like the new bright stuff churned up by Spirit has gotten the attention from the PI on Mount Itacha
Spirit Front Hazcam Latest Steve update QUOTE So what is this new stuff (which we have named Arad)? The same kind of salt? Something different? Similar concentration or even saltier? It was too tempting a target to pass up, and we're going to spend the weekend doing IDD work on it before moving on.

I think so.. it's spotty in distribution, not at all clear why.. Here it's pretty clearly in a drift of "fines" on rubbly regolith, not in the fines part of the rubble itself. This deposit must either be an aeolian layer, or salts deposited up into the fines by groundwater, which seems to have not cemented it. A really big question in that model is how is it loose and totally crumbly, not cemented.
I too have continually wished for a trenching tool on these rovers, as I commented some months back. Scuffing works, but it almost totally trashes any interpretible stratigraphy. |
