*Atlantis' Launch Scrubbed Due to ECO Sensor Problem*

/ Sept. 8, 10:54 a.m. EDT (1454 UTC)/
The launch of Space Shuttle Atlantis has been scrubbed until Saturday 
due to a problem with one of the vehicle's fuel system sensors. The new 
launch time is targeted for 11:14 a.m. EDT.

Earlier in today's countdown, launch controllers detected a problem with 
one of the four ECO sensors inside the hydrogen section of the space 
shuttle's orange external tank. The sensors monitor hydrogen levels 
inside of the tank and trigger the orbiter's engines to shutdown when 
gas levels drop below a specified level.

NASA Launch Director Mike Leinbach explained the issue to the crew 
adding that the launch weather for Saturday looks good and controllers 
will just have watch to see how the shuttle responds once the tank is 
again fueled for flight.
