Sol 199: amazing disappearing pebbles

[Paul Morris]

Check out the Sol 199 microscopic images for Opportunity.

Look at pairs of images that depict the same "scene."
Notice that in many cases, the pebbles (or grains) are
moved or missing between the two images of a pair.

Also in some of the images, there is a worm-like feature
poking out from a hole in one of the pebbles.

I think what you're seeing is before and after they press
the lens onto the soil. They do this pretty often to see
how things are shifted or pushed into the soil.

The irregular and random shapes of these spheres makes them
appear to be simple mineral deposits.

I looked at the MI images for many, if not most, of the Sols
and I have never noticed anything like in Sol 199 before.
