Looks like they are going to push for 3/4 ECO LCC for launch today.
But what good would a 3/4 ECO LLC do if both sensor #2 and #3 are having trouble (or if it's the electronics that controls them, so that you might get more than 1 wrong reading during launch)?
Or am I misunderstaning how things work here?
If they're talking about 3/4, then the issue is only with one of those two.

Great shot of LC 39 with the full moon at 10 oclock from the WEST (edit, thanks Dave) facing camera...just barely audible ground loop audio feeding through...slapping the headphones on to see if I can get a read on it.
ADD:
Inspection team audio...nothing sounding out of nominal...heading down to 195' now...irritating that they are running it so low...need to jump it about 6 dbu, so then its at least there...cmon PAOs

Perhaps we can have somewhat of a happy medium -- I don't mind the screenshots, but I would like to join in this request and ask for some restraint in the frequency of posting screenshots.

05:52:20 MER MGR Tyvek Action From Ed (-------)
If we go into 24 hour scrub, need to assess impacts of the Tyvek cover loss on F3L, since RSS will not be rolled back. When RCS comes on need to get them involved, including MOD assessment

Great shot of LC 39 with the full moon at 10 oclock from the North facing camera...just barely audible ground loop audio feeding through...slapping the headphones on to see if I can get a read on it.
It's facing west, not north.

Agreed.
One screenshot, not loads at once, per post, and not every five seconds. Thanks. ou crazy at launch, and during spacewalks, docking etc.etc. great, but not while she's sat at the pad, twiddling her ECO sensors

They want to make a decision prior to Crew Ingress!
I personally don't see them getting to the Launch Today Rationale because of the underlying assumptions of the current 3 of 4 rule. I have not heard from anyone to confirm if we are talking about two sensors as was posted here earlier...but if there are 2 sensors and the Point Sensor Box is the suspect we are no go for today - as I understood from the 121 flow.

The Tyvek cover came loose, at this point they just want to make sure there is no moinsture in the thruster that could freeze and prevent thrust firings.

Sensor 2 info is strange. Everyone I know is saying it's just the one sensor failed, so that's our position.

Possibly a typo?

Air Data probe IPR. Must be cleared by T-20min mark. Water droplet looks to be "evaporating", but the current & forcasted relative humidity does not favor complete evaporation. Possible "hip-pocket" waiver coming through in a few hours.

Mark, a question about way the computers take the ECO data...at what point in ascent are the sensors normally "armed?"
Oh, yeah, the other question: what sequence of failures would cause them to be armed prior to that?
Thanks.
