Well, I imagine it will go on after that, but I think they need to make a
limit that everyone worked to.

Maybe one or more of the science instruments cannot survive much longer than
that, and also, presumably, the power system must be based on rechargable
batteries, and we all know how flakey those can be in a demanding situation.

So, does anoyone actually know the answer to this?
