“Go” for Tanking

The Mission Management Team gave a “go” to begin loading Discovery’s
external fuel tank. The operation was scheduled to begin at 8:56 p.m. but
will be delayed slightly while the launch team investigates an anomaly with
a fuel cell pump motor voltage spike. Although this will delay the start of
tanking, it is not anticipated to impact tomorrow mornings launch. Launch
is planned for 6:21 a.m.

There is a 80 percent chance of favorable weather for launch. The primary
concern is a slight chance for ceiling and visibility constraints.

Live launch coverage will kick off on NASA TV and on NASA’s Launch Blog at
1:15 a.m. Monday. The Launch Blog can be found at www.nasa.gov/launch and
