  Sept. 8, 4:45 a.m. EDT
  
  At Launch Pad 39B, the loading of Space Shuttle Atlantis' orange external tank with about 528,000 gallons of liquid oxygen and hydrogen began on time at 1:15 a.m. EDT today. The "topping off" of propellants into the tank will continue until liftoff. All systems onboard the space shuttle, including the four engine cut-off (ECO) sensors, are functioning normally and are ready for launch at 11:15 a.m. EDT.
  

  
  That seems to be yesterday...

• ECO sensor#3 is working. - per George Diller on NASA TV
  
  Right now in a "go" configuration.

• NASA TV commentary has started, with PAO George Diller...nothing new was reported in the opening that hasn't already been reported here.

  FC#1 coolant pump motor phase A on AC1 is still dead.

  Hope this will not come in way of launch today.

  It won't. Unless they loose a second phase on FC#1.

• PAO relaying report that the final inspection team finds no water accumulation in the F3L thruster.
  
  The traditional crew breakfast photo opportunity also just concluded, so they'll be off to get a weather briefing and suit up soon.

• From NASA TV:
  
  ECO Sensor 3 is OK
  Fuel Cell is working as they want
  Thruster have to water in it overnight
  
  
  No problems so far!

• There is a flash light seen near shuttle on NASA TV and flame far off. Any info. what is that.

  Flash: Strobe light on top of the water tower
  Flame: The excess hydrogen burn-off flare stack

• Thanks. Whats news from pad 39B.

• Watch NASA TV ( http://www.nasa.gov/multimedia/nasatv/index.html ).

• From all reports, it's been a smooth countdown so far -- we're probably going to get more details on the behind the scenes discussions once Chris joins us.

• News from NASA's launch blog
  5:58 a.m. - We are still in our planned T-3 hour hold. The Ice Team members are now at the Mobile Launcher Platform level of the launch pad as they finish up their inspection. The team uses a portable infrared scanner that gathers temperature measurements on the surface area of Atlantis. Preliminary reports indicate no issues at this time.

• george (diller) said that it's very hot out and we did see ice melting off the tank (via camera 163). looking forward to a launch today!

• NTV is saying ECO sensor is good to go. Can someone tell me if it is "GO" because tanking made the sensor go wet or have they forced it dry and it answered OK? I posted this one level up on mistake. You would think an IT Manager would know how to navigate a website!

  The problem yesterday is still an unexplained anomaly (UA).  They don't know why they occasionally see this behavior, but based on past experiences, they developed a plan which says that launch is acceptable on the second tanking if the sensor works correctly (currently the case) or if it fails WET, like it did yesterday.

• Well the ECO sensor did go dry 5 hours after detanking. It when wet when it should've during the fast fill.
  
  "You would think an IT Manager would know how to navigate a website!
  No really, but I would expect an IT worker too
  
  The problem with these sensors is that they used the ECO ones, not the Delux ones

  Yes, but just because that behavior fit the pattern seen in previous experience, it doesn't mean that it is explained.

• Can any one confirm that there is no other Firing Room Audio available on the web until Nasa TV starts to carry it?
