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. |

Dust. They expected the dust to kill them soon after 90 sols.
To engineer the robustness and longevity to last 1000 sols ( i.e. design spec of 3000 sols as they design for minimum component life of 3x the requirement as I understand it ) from the outset, it would have put mass, volume, time and money over the edge. Doug |
