Paul Hunter, via Facebook asked:
Will the Mars Curiosity Rover have the longevity of the Voyager I, which 34 years later, is still providing information?
David - Well, we sure hope so. I think I’ll be well-retired by then, but it is nuclear powered so we won't have the problem of solar panels getting covered with dust. I guess really the only issue we’re going to have is that same nuclear power that keeps us going is also going to be firing off neutrons at us at a rapid rate. And those neutrons can cause damage over time so, we’re kind of in a race to get as much information as we can and if we last 10 years, well we’ll still be sending information back.
