According to the plan, LH2 and LOX should be at slow fill.

Actually, they should be transioning over to fast-fill right now.

Now It should get clear whether the ECO sensors are working properly ( If they've gone wet according to plan). Any words on this?

No. Not sure we'll hear anything unless there is an issue.

LH2 ECO #3 has failed wet. Checkouts are being performed.

If that's true, yuck.
What's your source?
Thanks.

OK, let's suppose that that guy is not kidding, what should happen if we have a failed ECO sensor in the LH tank? Should we rely on the rest and fly as is?
Didn't they R&R when this happened last time? My memory grows weary at this hour.

I'm not going to post any more on this beyond this post unless we get some corroboration, but the shuttle program developed a plan for this before STS-121. Let's wait, though.

Yep. R&R on both ET-119(STS-121) and ET-118(STS-115) at KSC.

I'm not sure but Discovery had a failed ECO sensor during its last flight. Whatever, if a repair is requested, this means rollback because the sensor is in the ET

Can be in the ECO Point Sensor Box which is located in Avionics Bay 5 in the aft engine compartment.

I wish NASA tv would switch to live coverage now already. Would be nice to hear the comms at KSC.

Yes, but that was not a ECO sensor, that was a 5% sensor in the LH2 tank. They were from the old problematic batch, but not swaped since they are not critical.
Let's hope Chris is online soon, he'll probably have some updates from the ET folks at KSC.

Confirmed: "Looks like LH2 ECO #3 just failed during fast fill... if not resolved this will put off launch indefinitely" - source

As I have checked multiple reliable space news sites(Space.com, Orlando Sentinel, Spaceflightnow.com, CBS News, FLA Today) and none even has a much a mention of the ECO sensors, I would recommend that this statement should be treated with the uttermost suspicion.

If there's a scrub now, wouldn't it be good to do a full count up to T -31 to spot other problems? Or would that cause problems in itself?

Didn't they make up some plans for trubleshooting this prior to the STS-121 launch?

I may have to apologise. This guy posted from a NASA ip address.
I'll do so right now.
To the original poster, sorry for being suspicious, but without at least some idea where the info came from (OIS loop, for example), it's hard not to be.
