Last I heard it was in danger of dying because the RTG power was running low and at aphelion there was a risk of the hydrazine freezing/exploding in its propulsion system. Well that was like a year ago and I haven't heard anything since. It looks like it should've passed aphelion by now and should be out of danger..... Its been going up there for over a full solar cycle, is it one of the missions on the chopping block because of the new humans on moon/mars thing?
