allright The Vagabond, stop right there, before you start having people think the rover landings are a hoax, and they (like the moon) were all

I never said that- especially not the part about moon landings taking place in a large hangar.
I -asked- at what point the unexpected life of the probe would cease to be realistic, not only for the solar pannels but for the wheel that was amping
out.
If this went too long- say for over another year, despite more minor technical problems which just "go away"- at what point might those of you who
are more technically familiar with the probe suspect that the probe had already ceased to operate but that its life was being falsely extended
(perhaps for PR reasons)?
If I were an organization that REALLY needed a PR boost after losing a really expensive craft with several highly trained people aboard, I would take
a probe with a relatively short lifespan and under-task it for its expected lifespan, allowing me time to do a lot of unscheduled extra work. One way
in which I could do this is giving the probe a battery life that let it work through the night so that travel time between objectives could be covered
when the probe was supposed to be down.
When the probe finally died, I could keep feeding out that "extra" work and claim that the probe had outlived its projected lifespan. If I had 2
probes I could do even better with this effect by making one of them "die" when in fact it had not, so that the other could be credited with not
twice as much life, but four times as much life or more.
Again, I'm not saying this happened. I'm sure NASA has -really- good engineers, even though for some reason they couldn't develop a solar-pannel
cleaner (or if they did, it's so incredibly good that it's classified).
So I'm sure these guys who are so brilliant that even their solar-pannel wipers are classified could have made a probe last this long with no foul
play. That is definately a STRONG possibility in my humble opinion.
However, since it is only my humble opinion and I have little technical knowledge about this mission, I was curious what doubts, if any, might be
raised by in the minds of more informed members if this probe survived for a year or two more. Is their any equipment on the rover which is easily
given to wearing out which could be used as a fairly solid expiration date?
