Michael Meyer, lead scientist for NASA's Mars Exploration Program, spoke at the recent Viking anniversary celebration. One remarkable quote:

"Considering how long the Spirit and Opportunity rovers have lasted beyond their design lifetimes, it almost boggles the mind to think how long MSL could last. It may be there to greet the astronauts when they arrive on Mars."

That's what I call optimism.
I always thought that the lifespan of an RTG was pretty predictable and that in case of MSL it lasted for about 2 earth years. Maybe he's talking about the solar array powered version?

Off topic...

But when we get around to sending a lander/rover into Shackleton Crater at the lunar south pole, will there likely be only a battery to power it, for a short-term mission? I can't imagine sending an RTG there if there is a hope to use any possible ice resources that may exist. And a solar panel wouldn't be of much use in a perpetually shadowed crater.
