sol 2403-2414-2435 stain changes:
OK, I still can't see any changes to the red dust on the deck near the sundial.
IF the changes to the stain are due to a steady westward wind as Oppy traveled east for the last month THEN why hasn't any of the red dust moved eastward???
Perhaps the red dust is immobilized and the stain material isn't?
I think that I have demonstrated by ratio color that the stain is a unique material on the deck - so what sort of property would allow it to move on the deck while the red dust does not?
It has been scientifically established that all atmospheric dust is magnetic - and except for the strongest magnetic dust - that dust is red.
SO, perhaps the stain is non-magnetic and therefore easily moved about on the deck by the wind?
Note that when the rover was traveling backwards mostly south a steady west wind would have pushed unbound dust to the left ( looking back ) - which is what was observed.
We here on the blog ( yay team! ) have established that the stain appeared suddenly in the depths of Victoria crater so it is extremely likely that a material is not-atmospheric.
Now, the atmospheric dust has been found to be in the 1.5 micron range ( very fine ) - so the dark stain material would have to be even finer to be moved so easily by the gentle vacuum winds of Mars.
BUT ( and this is an important but ) there appears to be a "lumpiness" to the stain in the highest resolutions done to date - utterly inconsistent with a very fine material easily moved by the wind.
All of this leads to the assertion that the "stain" material can not be fine dust of any sort.
SO. what can it be? Ideas?
It sure would be nice if the "big guns" would weigh in on this trifling matter.
