Despite the above, the hold continues to be extended with no word on what the issue is (if there is one).

Probably double and triple checking the systems again

Current view (obviously not much to be seen apart from the stationary scene):

T-6hrs 38 minutes and COUNTING! Preps for prop load are now proceeding in earnest as the count has begun.

Chilldown of the LOX system is in work.

The countdown for the wet dress rehearsal has resumed at 10:52 a.m. EDT and clocks have picked back up at T-6 hours, 40 minutes on the clock (L-7 hours, 20 minutes). A new planned T-0 of 6:02 p.m. has been established.

Sensor limit reached for LOX.... hopefully it's a quick settings change and they were too conservative like green test 1

There continues to be no sign of propellant loading. Running about ~5 hours behind schedule.

I would rather all the bugs were ironed out now than on launch day. NASA cannot afford this launch to fail - they might not get another try I suspect.

I agree.

What concerns me is that since this issue is very close to identical to one encountered by the Green Run and solved then almost 1- 1/2 years ago. That brings into question as to whether these procedures had even been revisited and updated since the Green Run with lessons learned.

How is this the same? The green run had the issue during firing while this one is with the LOX sensor.
