How about this:
Opportunity, SOL 15, Microscope, upper right,
I see definite segmentation, somewhat similar
to the ALH meteorite, but in this case must be
grown-ups (I checked out the scale, much larger....
this image=3x3cm square).

Has this already been explained,
or am I the only one who sees this?
Can we get it to go back there for some
more pics before they're done? JD in Colorado
