*Launch Day Arrives, Tanking Completed*

/ Sept. 8, 6:15 a.m. EDT (1015 UTC)/
The launch team has reported that an ECO sensor on the hydrogen side of 
the external tank has failed. At this time the team is pressing forward 
with launch preparations. Mission Management Team members are meeting at 
this to determine if they will consider launching with three working 
sensors or if it will be necessary to de-tank and come back tomorrow.

At Launch Pad 39B, the three-hour process for loading of Space Shuttle 
Atlantis' orange external tank with 500,000 gallons of liquid oxygen and 
hydrogen was completed at 5:46 a.m EDT this morning. The "topping off" 
of propellants into the tank will continue until liftoff. All systems 
onboard the space shuttle are functioning normally and we continue to 
press toward a scheduled launch time at 11:41 a.m. this morning.

Throughout the morning, the STS-115 astronauts will prepare for launch 
in the Operations and Checkout Building's crew quarters before taking 
the 20-minute ride to the launch pad about 7:50 a.m. this morning aboard 
the Astrovan.

Launch weather remains at 70 percent "go" for launch, with the primary 
concern for rain within 20 miles of the Shuttle Landing Facility. No 
other issues are being addressed by the launch team at this time.
