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. |

"High-centered" usually means that the vehicle's center of gravity is being supported on something other than the drive surfaces, so there's little or no traction, Lyford.
Paolo, it's good that there's some significant lateral slope. Are there any transducers or some indirect means to measure how much of Spirit's weight is resting on the wheels? That would be good to know for strategy development. Based on your description of the situation, if it was me in a truck or something I'd gun it forward, expecting the left wheels to slip & hoping that the right wheels would grab enough to spin me downslope (leftwards) & pick up dual traction again. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
