  Earlier it was mentioned that they may drain back down to 5% and try filling again. Could this possibly be done and still be successful today in time for a possible launch?

  Even if they tried filling again, it would be for troubleshooting.
  
  I know there's some anxiousness out there for a launch, but if you follow the shuttle program, you will learn to be patient.

• That's it.  Scrubbed.  Now we see what they can find from the troubleshooting.

• OFFICIALLY SCRUBBED!

  That depends on MMT.  If they find something, then it could be weeks.  It all depends on the data..

  Way too early to know that with any reasonable certainty.

  To be honest, I think this is now going to be January, as per troubleshooting notes. We'll see what the MMT decide. Too early to say yet. They could even try again tomorrow...we'll see.
  
  Remember, we're also watching the sensors still. They will go through some more tests.

• Watching the LH2 ECO sensor, waiting to see if/when it clears.
  
  Hoping to get someone from senior management to talk with PAO, but they are extremely busy right now.

  Yup.  At this point, they are probably several steps away from being able to talk about a new launch date.  It's mostly dependent on a lot of troubleshooting (hinted at last night by Doug Lyons that they'd start after detanking with going into the aft).
  
  They have to collect data, analyze it, and discuss what to do.  And then possibly repeat that sequence.

  January won't have that bigger impact on the schedule as if all goes to plan we could get 6 in 2008 or 5 in 2008 and then 5 in 2009, so I think we're pretty flexible at the moment...

  If they attempt on Monday and fail to launch, then must standdown for 48 hours to replenish Orbiter cryogenics (fuel cell fuel). This means NET Thursday.. This is per Leinbach on Saturdays Post MMT conference

• Have there been concerns in the past about how all the tanking and detanking may affect the integrity of the ET foam?
  
  I seem to remember a change was made to the recently around how long the stack was on the ground after the ET being filled? Not sure exactly...
• #194 by Ford Mustang on 09 Dec, 2007 11:33
• Stopped flow on LO2, for preparations with draining LO2.
  
  Countdown clock will continue to count backwards, but they have scrubbed.

  Very unlikely to attempt on Monday -- that would have been for something like KSC weather.  They have an unexplained problem and new circumstance; can't just recycle.

• LO2 detanking has commenced.  Will be a few minutes until they see indications of it on their screens, but it has started, nonetheless.
• #197 by MKremer on 09 Dec, 2007 11:34
• I'm going to be a Gloomy Gus and predict this will end up being a rollback, and launch maybe even a week or two later than the Jan. 2nd date mentioned.

  It was mentioned in yesterday's post MMT that the tank is capable of 13 cycles.  I believe that means a fill and drain is 2 cycles (can anyone confirm that for me?)
