• LO2 has transitioned to fast fill.
• #124 by psloss on 09 Dec, 2007 10:46
• PAO says to expect to know about how things are going on the LH2 side in the next half hour.
• #125 by Chris Bergin on 09 Dec, 2007 10:47
• About 10-15 mins from the first SIM test (command sent to turn ECOs from WET to DRY and back again) I believe.
• #126 by psloss on 09 Dec, 2007 10:48
• LH2 5% sensors are wet and transitioning to fast fill.
• #127 by Chris Bergin on 09 Dec, 2007 10:49
• No issues with the ECOs so far.
• #128 by psloss on 09 Dec, 2007 10:50
• PAO: LH2 ECO sensors have "cycled" and all are currently working.
• #129 by ntschke on 09 Dec, 2007 10:51

• Sensor #3 has failed.

   

• #130 by psloss on 09 Dec, 2007 10:51
• PAO: LH2 console reports that one of the LH2 ECO sensors (#3) has failed (presumably "WET").
• #131 by Chris Bergin on 09 Dec, 2007 10:52
• Crap Will get details on the exact problem.
• #132 by Ford Mustang on 09 Dec, 2007 10:52

  Yes -- they said that in this case, they'd have a lot of troubleshooting to do, today and in the days ahead.

• According to yesterday's LCC update this is a scrub and essentially now becomes a tanking test.

  Delays in general are always a possibility.
