In preparation for the targeted Oct. 23 launch, Discovery is set to roll from the Vehicle Assembly Building out to the Launch Pad 39A aboard the crawler transporter this weekend. Earlier in the week, the orbiter was attached to the external fuel tank and twin solid rocket boosters atop the mobile launch platform.
In the predawn hours Thursday, the payload canister for mission STS-120 arrived at Launch Pad 39A at NASA's Kennedy Space Center. The Italian-built U.S. Harmony module destined for the International Space Center will be transferred to Discovery's payload bay once the space shuttle reaches the pad.

The pressurized component was named "Harmony" by U.S. students in a nationwide contest. "This module will allow all international partner pieces of the station to connect together, so it's really wonderful that kids recognize that harmony is necessary for space cooperation," said Bill Gerstenmaier, NASA's associate administrator for space operations, when the six winning schools who submitted the name were announced.
