All the latest MI images from Opportunity shows this part of the rover:
http://qt.exploratorium.edu/mars/opportuni...KCP2957M1M1.JPG The only thing I can think of is that it is an image taken with the IDD stowed. Actually the front hazcam pictures confirms this. What can the reason for this be?  A problem with the IDD so it didn't unstow, but somehow the MI carried out its tasks?

Here's the information I have. At the beginning of the unstow sequence, the IDD tripped the circuitry that senses a motor stall (high current). The trip happened almost immediately after the azimuth motor started, which strongly suggests the arm is not physically jammed. (In that case, it would wind up before stalling.)
Hopefully it was just a glitch, such as a momentary current spike, but it takes a little while to sort out these things from a distance. To me, it seems unlikely that there is a permanent problem with the arm. |
