*Atlantis Set for Launch Today, Tanking Begins *
/ Sept. 9, 5:10 a.m. EDT (0910 UTC)/
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.(1515 UTC)
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 later this morning aboard the
Yesterday the launch was postponed when launch controllers detected a
problem with one of the ECO sensors inside the liquid hydrogen section
of the space shuttle's orange external tank. The sensor system is one of
several that protect the shuttle's main engines by triggering their shut
down if fuel runs unexpectedly low.

The Mission Management Team decided to wait another 24 hours before
launching to give the engineers more time to study the sensor data.

With this mission, NASA is ready to get back to building the
International Space Station, marking the first time in almost four years
that a space station component has been added to the orbiting outpost.
That also means the shuttle program is coming up on some of the most
challenging space missions ever.

During their three spacewalks, crew members of Atlantis will install the
P3/P4 integrated truss and a second set of solar arrays on the space
station, doubling the station’s current ability to generate power from
sunlight and adding 17.5 tons to its mass.
