Here's a shot of the rabbit at the Opportunity site taken by the Panoramic camera on Sol 2

I wish nasa would release more color pics. I don't buy the insulation theory. It looks like it has too much substance to be insulation. Now, the fact that similar objects appear at the two sites is important. A common software/hardware defect could explain it. But the photos taken by Opportunity showing the shadow discredit any glitches.

Yep, the torn insulation theory isn't very convincing to me, either, mainly because I've seen a zillion torn things in my lifetime and that thing simply doesn't look like something that's been produced by natural tearing. It could be, of course, but it just doesn't look like it.
