The Rosetta spacecraft woke up successfully from 2½ years in deep hibernation, whilst it's catching up with comet 67P/Churymov-Gerasimenko (try saying that half a dozen times when pissed!).
That means that one of my colleagues definitely has a job for the next couple of years, and I need to finish setting our operational servers up.
We've yet to hear exactly what state the spacecraft is in, but we should get that information shortly. With luck it'll be in exactly the same condition as it was before hibernation.
