We may have the same scenery for quite a while. From the latest release:
QUOTE The rover team... has suspended driving Spirit temporarily while studying the ground around the rover and planning simulation tests of driving options with a test rover... "Spirit is in a very difficult situation," JPL's John Callas... said Monday. "We are proceeding methodically and cautiously. It may be weeks before we try moving Spirit again."
In the past week, the digging-in of Spirit's wheels has raised concerns that the rover's belly pan could now be low enough to contact rocks underneath the chassis, which would make getting out of the situation more difficult. |

Here's a wild thought that would be more a later move of desperation. I'm not certain what kind of mass ratios we are dealing with but would it make sense to extend the arm and IDD to slightly shift the CG, and add to the traction/load on a preferred wheel or wheels?

If anyone on the planet Earth can get us out, it is Paolo ! Thanks for your trust in my capabilities, but I have assembled a team that will actually do the work. Since we will be doing some testbed analysis, you won't see much changes in the scenery for a while, don't interpret this lack of mobility activity as unsuccessful motion.
