I hate to be the bearer of bad news, but I just heard that there is a serious problem with Spirit's right front drive actuator after yestersol's drive. (This is the actuator that had high currents in the past and led to the backward-driving strategy.) It will take awhile to evaluate the situation, but early speculation is grim.
In a worst-case scenario, they can still drag the bum wheel along, but don't expect another summit view. Best-case scenario would be a rock or debris jammed in the wheel. This is a heads-up, sorry I can't really give more info at this time. I still thought you all would like to know. |

First impression: the right front wheel looks like it is locked.
But if you look at images from last year, you can see that Spirit created trenches when it traversed soft material. Image from sol 313 for comparison http://marsrovers.jpl.nasa.gov/gallery/all...00P0745R0M1.JPG I assume for now that the wheel will turn when it meets enough resistance. |
