Well, since this thread has recurred and there seem to be people with good knowledge here, I've got to ask how a spacecraft that has lost its ability to aim antennas at Earth or align solar panels with the sun could possibly be diagnosed with having a time tagging problem? Jim Lux pretty well demolished the idea that time had anything to do with it, IMHO.
Seems to me that the DSN doesn't listen to Deep Impact continuously because it has other spacecraft to track. So there's no growing anomaly to indicate a future problem. One time communication is fine, the next time there is no answer. Pretty difficult to diagnose a problem from those symptoms. Used silver cell batteries for an upper atmosphere density probe in 1958. They're still around, but not suitable for long missions. What kind of battery (not RTG) would a deep space probe use? Thanks for any answers.
