In the White Room on Launch Pad 39A at NASA's Kennedy Space Center, STS-120 Pilot George Zamka is helped by the closeout crew to put on a parachute and get ready to enter space shuttle Discovery for liftoff at 11:38 a.m. EDT. The STS-120 mission will be the 23rd assembly flight to the space station and the 34th flight for Discovery. Payload on the mission is the Italian-built U.S. Node 2, called Harmony. During the 14-day mission, the crew will install Harmony and move the P6 solar arrays to their permanent position and deploy them. Discovery is expected to complete its mission and return home at 4:47 a.m. EST on Nov. 6. Photo credit: NASA/Scott Haun, Tom Farrar, Rafael Hernandez
