[Isocops] IBEX Goat Herder for 13 Dec 20

[Nigel Angold]

So that’s dodgy apogee contacts for the last 2 orbits. Anything to be concerned about? Or were they both predicted to be marginal?

Thanks,
Nigel

I was able to verify the inertial maneuver was successful and that we had another star tracker reset. I was able to reset the latch values for the tracker reset. Although it did take a couple tries to get the commands on board. The last sample of data that I saw was @00:45:00. Then @00:49:00 I asked SSC to bring down the carrier and terminate all tracking support.
