George Diller back...they will continue filling for the next half-hour to facilitate troubleshooting.

Interesting that it was only ECO #3 and not 3 AND 4 as was the case on Thursday. Per the previous flight rules, 3 of 4 would have been acceptable. Now we're looking at a possible January launch if they can't figure it out at the pad. Damn.

Well, looking at this from the half-full side, this is new data (well, a new pattern) and may help them get to a root cause.

Worth mentioning to L2 users, but the plans for this are available with the repair timeline graphs and what they'll now get out of a tanking test.

Plan is to stop filling after 30 minutes, see if any more data needs to be collected. If not, they will drain at that point.

PAO says an official scrub hasn't been called, but it's somewhat academic.

MMT is meeting to discuss the situation.

Does this mean MMT will discuss the option of continuing the countdown with 3/4 sensors?

Wayne sounded pretty firm. I don't think he'll let this one slide.

Maybe still a small chance the MMT will not scrub?

MMT has asked propulsion to come up with a timeline on how long it would take to drain LOX and LH2 to 5%. Will be a MMT meeting shortly to discuss what the official status will be. They have not declared an official scrub, but the LCC will not allow them to continue in this formation.

seems less likely to be wiring that's common to both sensors then. perhaps it is actually a fault with the sensors, rather than wiring or connectors.
a pity they can't launch with only the one failure. but if one sensor "fixed" itself today, then maybe tomorrow the other one will be fixed too. fingers crossed.

Was/is there an option of draining, collecting data, and refilling and still make the window? (Assuming of course that all sensors function on the refill)

Is that what the PAO was just hinting at?

It could argued the other way, though, too: this situation is different than other launch campaigns and the data is telling them to stop and look deeper.
Which is why it's nearly pointless to speculate -- we don't have sufficient insight on the outside to make those conclusions in real-time.

Gonna get pretty busy in the firing room right now.
'This could be a good thing, because we will get data from the launch attempt, and from the test this morning, which might help us find the root cause.'

No official scrub yet, but LCC rules are LCC rules and this configuration denotes scrub.
