NASA's Curiosity Mars Rover

After 8 years of ascending the mountain, this is what it's come to. As this episode documents very nicely, the rover's brush tool has been working perfectly all this time... until now. After stumbling over all that raw sulfur and being forced to backtrack over all this rocky terrain - he's faulty, malfunctioning. Kept babbling on about his mission.

To quote Mars Guy:

that post, spinning at a few hundred RPM, appears to have been jammed into the rock, which was soft enough to result in a shallow hole. Now the remaining question is, after hundreds of uses without jamming the post - what went wrong this time?

These astro-droids are getting quite out of hand. Even I can't understand their logic at times.
