Seems to me that we have moved forward about a foot at some point--are we free of the mess?

Not yet, IMO. Based on the data from the pancam web the latest "drive" was done in six steps and the slippage was quite high on all of them: 93%, 93%, 88%, 78%, 89%, and 94%. |

According to the latest Flight Director Report Opportunity's wheel stalled.

Is this the same as with Spirit's wheel, that it won't rotate?

In the past, they've used the word "stall" to indicate a one-time event...i.e., a mechanical component did not respond to a given command. Have to wait & see if it's a persistent problem or not.

Forgetting the MECA story for a while, here's a colourisation of a beautiful layered rock imaged by Oppy... hope some of you like it

What's not to like? Beautiful, Stu, thank you!
(STILL wanna take a rock hammer to these things & look between the layers.  Guess it's up to my great-great-great, etc. grandsons and/or daughters to do so, though...rats.)

At least we have something interesting to look if we're stuck here for the rest of the mission.

Looking back at some of the movements made while they were taking closeups of the wheels I suspect it was the steering motor that stalled.

Big news from the new PS update:
QUOTE ...the rover experienced a spike in the electrical current to the motor for its left front wheel, an event ominously similar to what Spirit experienced just before it lost the use of its right front wheel for good back in March 2006... Not surprisingly, the team decided without much debate that it was time for Opportunity to rove on and out of Victoria. "We want to get out of the crater as quickly as possible," Callas said

We had started to discuss the news that Oppy is on her way out in two separate threads, some posts moved to the Leaving Victoria crater thread. Lets continue things over there.

A few of us here probably know just how hard that must have been to pull together, to much kudos to the CCC for managing it

Whoa! I studied that panorama for quite a while. I realized I was staring too long when the muscles in my gaping jaws started to cramp.
That was seriously painful. Be warned.
