Space shuttle Discovery's STS-128 mission crew members arrive in T-38 training jets at NASA Kennedy Space Center's Shuttle Landing Facility. Seen here are Commander Rick Sturckow and Mission Specialist Patrick Forrester. The astronauts will be taking part in terminal countdown demonstration test activities that include equipment familiarization and emergency egress training, and will culminate in a simulated launch countdown aboard Discovery. The mission will deliver a new crew member and 33,000 pounds of equipment to the International Space Station. The equipment includes science and storage racks, a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill. Launch of Discovery is targeted for late August.
