At KSC's Shuttle Landing Facility (SLF), overhead cranes are fitted around the S0 truss segment to move it onto a flatbed trailer which will transfer it to the Operations and Checkout Bldg. for processing. The truss arrived at the SLF aboard the "Super Guppy" aircraft (in the background) from Boeing in Huntington, Calif. During processing, the Canadian Mobile Transporter will be installed on the S0 truss, followed by power distribution system modules, a heat pipe radiator for cooling, computers, and a pair of rate gyroscopes. Four Global Positioning System antennas are already installed. A 44- by 15-foot structure weighing 30,800 pounds when fully outfitted and ready for launch, the truss will be at the center of the ISS 10-truss, girderlike structure that will ultimately extend the length of a football field. Eventually the S0 truss will be attached to the U.S. Lab, "Destiny," which is scheduled to be added to the ISS in April 2000. Later, other trusses will be attached to the S0 on-orbit. The S0 truss is scheduled to be launched in the first quarter of 2001 on mission STS-108.
