Discovery Remains on Target for October*
Even with the work in progress on the external tank, the STS-120 launch remains targeted for Oct. 23. Since the schedule leading to Discovery's liftoff contains about five extra days, mission managers believe it provides enough room to make the changes and still launch on time.

The preparation of Discovery continues in the Orbiter Processing Facility at NASA's Kennedy Space Center in Florida. In the nearby Vehicle Assembly Building, stacking and closeout of the solid rocket boosters are finished. Pending completion of foam repair work on the external tank's liquid oxygen feedline support brackets, attachment of the tank to the boosters is targeted for Sept. 5.

The Expedition 15 crew wrapped up a busy week of robotics and set the stage for future growth of the International Space Station with the relocation of Pressurized Mating Adapter-3 (PMA-3).

Thursday, Flight Engineer Clay Anderson used the station's robotic arm to move PMA-3 from Unity's port docking mechanism to its nadir, or earth-facing, docking mechanism to make room for the installation of the Harmony node, which is set to arrive on Space Shuttle Discovery in October.
