Might be appropriate to note that this vehicle had two wet dress rehearsals, which could have been due to a tanking problem on the first WDR that is recurring today. This is of course speculative, because I've previously asked a couple times about the reason for the two WDRs, and nobody here seemed to be at liberty to reply.

Got a bit sporty in here just then, deleted back. No point asking if there's a scrub if it's not been posted.
We've got the above note. SFN's got them offloading. Both of us aren't saying scrub yet.

Fuel detank started about 30 minutes ago. Note (our sources) they have one troubleshooting step left, but probable scrub.
So it's not over yet.
Good question from Butters, especially as the WDR was noted as an EELV positive with regards to STS-133's tank issues.

False alarm, other sensors indicated everything was okay, IR camera said flare stack was working fine.

Still plenty of time to recycle back into tanking I assume?

The November 5 & 6 launch windows were 4 hours, couldn't find up-to-date info for today's window.

It's secret. Checked back on the ULA e-mails about this launch and it was noted "The launch window for the mission will not be released".

SFN say the window is 'a few hours' which would enable the problem to be fixed and launch attempted again.

Let's keep speculation to other sites, yeah?
ULA officially note:
During today’s cryogenic fueling, anomalous temperature readings were observed on the port and starboard strap-on common core boosters. At this time, fuel loading has ceased and the launch countdown is on hold. Mission managers are currently studying the situation to see if this can be satisfactorily resolved to continue with today’s launch attempt.

Delta IV Heavy NRO Mission Scrubbed
Cape Canaveral AFS, Fla. (Nov. 19, 2010) - The launch attempt of the United Launch Alliance Delta IV Heavy with a National Reconnaissance Office payload was scrubbed today. During the launch countdown, anomalous temperature data signatures were detected on the port and starboard strap-on common core boosters during cryogenic fueling. When detected, mission managers halted the countdown and stopped further tanking of the rocket. After evaluation, the decision was made to scrub today’s launch attempt. Mission managers are currently studying the situation to determine a corrective action plan.
The Delta IV Heavy and payload are safe and secure at this time. When a decision is made confirming the date of the next launch attempt it will be announced.

Dang, I go to check out the launch status for todays rockets and another dissapointment. Man, it seems like I've been waiting to see a rocket launch forever. Spacex gets delayed over and over, shuttle gets delayed over and over, and now Delta IV heavy. I'm really looking forward to seeing Delta IV heavy cause I've never seen one of these launch. Looks really cool though strapping three of the first stage boosters together like that.
