The specs? Those specs called for a three month life with a
probability of failure not greater than 5%. That wouldn't
tell you the answer you asked.
What we need is the reliability/life cycle model. I do not
personally have access to that model, so I cannot offer a
estimate of the life of those Mars rovers on that basis.
That being said, there is some info that might be useful
for this wager you propose Jeff. I don't know what type
of batteries are in these rovers, but generally that is the
subsystem that has a definable lifespan. If we can find
out what type of batteries they use, I can offer a useful
estimate of a time/probability distribution.
I heard that the battery/solar charging system was not
designed to survive the Martian winter. They did once, so
perhaps they will survive again.
