The Closeout Crew in the White Room help STS-128 crew members complete before entering space shuttle Discovery.

On Launch Pad 39A at NASA's Kennedy Space Center in Florida, the Closeout Crew in the White Room help STS-128 crew members complete their suit-up before entering space shuttle Discovery for the 11:59 p.m. EDT liftoff. Seen here is Commander Rick Sturckow. The first launch attempt on Aug. 24 was postponed due to unfavorable weather conditions. The second attempt on Aug. 25 also was postponed due to an issue with a valve in space shuttle Discovery's main propulsion system. The STS-128 mission is the 30th International Space Station assembly flight and the 128th space shuttle flight. The 13-day mission will deliver more than 7 tons of supplies, science racks and equipment, as well as additional environmental hardware to sustain six crew members on the International Space Station. The equipment includes a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill. Photo credit: NASA/Sandra Joseph-Kevin O'Connell
