trust in JPL
That's not good news, for sure. But not yet a disaster, because as long as the computer has a pulse there's hope that the ground controllers can find a way to reboot it or patch the software. This is exactly the sort of problem that historically has showcased the genius of JPL. It's hard to come up with a planetary mission that they've failed to save with a little brilliant remote programming. It's not like the emitter has burnt out or anything irrevocable like that.
I'll keep my fingers crossed, but the knowledge that JPL is on the case is a great comfort.
