STS-128 crew members put on their suits before heading to the Astrovan for the drive to Launch Pad 39A.

In the Operations and Checkout Building at NASA's Kennedy Space Center in Florida, STS-128 crew members put on their launch-and-entry suits before heading to the Astrovan for the 3.4-mile drive to Launch Pad 39A. There, crew members will complete their suitup and enter space shuttle Discovery for the 1:36 a.m. EDT liftoff. Seen here, Mission Specialist Jose Fernandez is ready for launch. 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. The mission is the 128th in the Space Shuttle Program, the 37th flight of Discovery and the 30th station assembly flight. Photo credit: NASA/Kim Shiflett
