[Isocops] IBEX Goat Herder for 17 Nov 2024

[Perry, Timothy E [US] (SP)]

All,
    Tonight, we had an issue with the spacecraft. At AOS we noted that the Hmlogs for the BCR and Flight Computer were steadily incrementing. We also noted that the Thrust time out counter had not reset to zero. We reset the counter to zero and were able to dump the flight computer back orbit data. The plan for tomorrow is to reset the BCR first and if that clears the issue than we are back to routine operations. I f we need to reset the Flight computer, then we will have to safe the instrument and proceed with the reset. I have 2 contacts scheduled for the recovery and one for the initial resets.
Here are the contacts I have scheduled for tomorrows planned operations
