I thought I'd kick off a new thread with this announcement:

Oh, they're something you have to live with, alright. Statistics are hell, but it just doesn't seem right for the spacecraft to run into a red alert mode only some 2 months (?) into hibernation. Statistically, that can mean anything from an unlucky fluke to a spacecraft that has to be babysitted every month. It could be a combination of the two for all we know, a cosmic ray trip triggers a software corrective action that's buggy and you wind up in a reset.
Take Cassini for comparison - it has a couple of trips of a certain power-related circuit (I forget) per year due to cosmic rays and that's with a spacecraft doing stuff basically 24/7. The fact NH had a mostly trouble-free flight up until hibernation does seem to suggest it's in some way related to that mode, but all this is wild speculation. Hopefully, Alan and co. will find out the real sequence of events soon enough. -------------------- |
