MIRI recently reached it's target goal of an insanely cold 7K a few days ago. It's now below 6K. Apparently part of the delay that I didn't realize is that they had small heaters operating to slow it's cooling until a certain point, in order to ensure no ice buildup occurred. The more you know, the more you understand. Once they had everything running full, it dropped like crazy, almost 80K in 15 days.
The goal for the mirror temp isn't quite there yet - 36K, currently at 42+ and slowly dropping. But all appears to be well.
