Following a review of Space Shuttle processing activities at Launch
Pad 39A, mission managers today confirmed the launch of Space Shuttle
Endeavour for Monday, Nov. 11, at the preferred launch time of
12:58:40 a.m. EST.

The planar launch window on Monday extends from 12:53:39 – 1:03:39
a.m. EST with the preferred launch time reflecting a flight day three
rendezvous and docking with the International Space Station. The
launch window will be updated to coincide with the latest orbital position
of the Space Station and will be announced at the T-9 minute hold.

STS-113 is a scheduled 11-day mission with a planned KSC landing at
about 8:17 p.m. EST on Nov. 21.

This mission marks the sixteenth Shuttle flight to the International
Space Station and the fifth Shuttle mission this year. Mission
STS-113 is the 19th flight of the orbiter Endeavour and the 112th flight
overall in NASA’s Space Shuttle program.

On mission STS-113, astronauts will deliver the Expedition Six crew
and the Port 1 (P1) Integrated Truss Structure to the International
Space Station. During the seven days Endeavour will be docked to the
Station, three spacewalks will be performed dedicated to connecting the
P1 truss to the port side of the S0 truss, already in place on the
Station.

The STS-113 crew includes Commander James Wetherbee, Pilot Paul
Lockhart, and Mission Specialists Michael Lopez-Alegria and John
Herrington, and Expedition Six crew members Commander Kenneth Bowersox, Donald
Pettit, and Nikolai Budarin, a cosmonaut with the Russian Space
Agency.
