Behind Ivins is Scott Thurston, of the VITT office. The crew is at KSC for Terminal Countdown Demonstration Test activities, which also include a simulated launch countdown. A key element in the construction of the International Space Station, Destiny is a pressurized module designed to accommodate pressurized payloads. It has a capacity of 24 rack locations. Payload racks will occupy 13 locations especially designed to support experiments. The module already has five system racks installed inside. Launch of STS-98 on its 11-day mission is scheduled for Jan. 19 at 2:11 a.m. EST
