3D "super-res" infrared soil detail:

I put the "superres" in quotes because it's not really a superres -- but once can be created from the original data. As I surmised, the "twichy eye" filter shots are a routine sequence that the Phoenix guys are using to get 10 pounds out of their 5 pound bag.
The best we can do is average out some JPG artifacts -- but to my eye the result is worth the effort.
Er, say, what are those small white circles with a dark "grain" dead center with a ring of grains surounding the circle?
Anyone? Anyone?
And here are the sol 49 and 50 RAC RGB views of the soil in the scoop:

I find the dark splotchy spots in the sol 40 image, er, curious.
The rasping operation seems to have shaken all of the dark soil out of the scoop and a lot of the redder stuff too -- but not all.
Remember, you can't compare images made with the JPGs -- only features within a single image.

Interesting place, Mars.
