She's there! Opportunity drove down to the "Cook Haven" bright outcrops on Sol 3512.
Even better, news via Twitter that currents on the front right wheel are back to normal. Phew. |

Of course RF doesn't steer, but that still leaves three steering wheels. Walfy's idea actually sounds like the second good idea we've heard (after the obvious rock-popped-out-while-being-driven-over).
The basic problem is that Pinnacle Island moved a considerable distance, as the debris on its rover side indicates. The slopes here are fairly subtle, around 15 degrees. In Mars gravity, that seems to be too shallow for a rock shaped like PI to roll easily. So PI must have been given a kick somehow. Getting squeezed under a wheel, and now Walfy's idea are the only ideas that seem to work. (The wheel rotation speeds are so slow that I can't believe PI being trapped inside a wheel and then spat out. And the odds of a meteor strike nearby have to be incredibly small.) |
