It seems about the right time to start a new thread as we have now turned East to Endeavour.
Hope no one minds... -------------------- -- Robin

A stall would result in a dramatic change in the current signature on the motor would it not? Something that would almost certainly flag up a drive fault.
Have we ever heard of a motor stalling, but the drive continuing regardless? I know that Spirit was using a cautious automatic system to recover from stalls within a sol, but for a drive motor to stall on Opportunity and yet the rover carry on driving would be highly unusual.# I think we're just seing something of an NPE (Near Purgatory Event) Note, in FredK's image - the 100% perfect track's just outside the churned material. The Front and Rear wheels have similar track width, but the middle wheels are slightly inboard of that. That clear track mark infers the FL wheel turning normally at that time. |
