STS-117 Media Showcase

At a media showcase in the Space Station Processing Facility, reporters and photographers get a close look at the S3/S4 integrated truss segment. The starboard 3/4 truss segment will launch aboard Space Shuttle Atlantis on mission STS-117, targeted for March 15. The element will be added to the 11-segment integrated truss structure, the station's backbone. The integrated truss structure eventually will span more than 300 feet. The S3/S4 truss has two large solar arrays and will provide one-fourth of the total power generation for the completed station.
