STS-128 Mission Specialist Danny Olivas is donning his launch and entry suit for a fit check before the simulated launch countdown at NASA Kennedy Space Center's Launch Pad 39A. The countdown is the culmination of terminal countdown demonstration test activities to prepare the STS-128 crew for launch on space shuttle Discovery's STS-128 mission. Discovery will deliver 33,000 pounds of equipment to the station, including science and storage racks, a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill. Launch is targeted for late August. Photo credit: NASA/Kim Shiflett
