The core can only be tanked 9 times, so here's another reason not to repeat the test... ?
End of mandate. It is customary for political appointees to submit their resignations when a new Presidential Administration comes in. The oncoming Administration can ask that they stay on until they have nominated a replacement.Is the administrator giving up or is it the end of his mandate ?
So, whatever happens the actual launch of Artemis 1 would go ahead anyway?

Well, the real hydraulics worked great during the first attempt. What got them was too conservatively set test parameters that was derived from computer models of the system. Now that they have updated the models with real world data gained from the 67 seconds of actual run time, things should be better. And of course the MCF was just a redundant leg of instrumentation which is why the test continued last time until the hydraulics system parameters got them.Lets hope the hydraulics work better then.

So all issues from the first attempt have been resolved and understood.
