Old story. That was early in Opportunity's mission.
March/2004, I think it was?
So far, the RAT team at JPL has FAILED to duplicate
that rotini shape with any rock or mineral conglomerate.
And the geologists on this website have failed to
offer a plausible explanation of the Rotini shape solely on geology or geophysics.
Obviously, we can rule out Rotini pasta as an explanation...
Unless a hungry JPL employee in a bunny suit...Oh never mind!
