Re: Well, crap....
Maybe, it sounds like it's the rate at which they get to do interesting science is reduced (once every 56 days), rather than a complete cessation. That's not so bad really, considering.
I agree, they most certainly have been very successful indeed. I think that the entire run of missions going back to the 1960s, 70s, including the European, Japanese, Russian and others, has overall been a stunning display of just what engineers and scientists can pull off when given the chance. The value for money, even including the failures and difficulties, has been very good indeed.
