You know, that makes me wonder: What does everyone think is the weakest link (system) in the rovers, the one that is expected to fail first and effectively disable the robot? This would be a system that just couldn't be made more robust, (almost) regardless of cost.
I think it would be the batteries. At a certain point, there's little one can do to increase their lifespan.
I would be quite surprised if they didn't know the answer already - maybe Dave can chime in after we have a few guesses...
