Workers look that will be attached to the Integrated Truss Structure ITS Z1 on the International Space Station.

Workers in the Space Station Processing Facility look over an S-band Antenna Support Assembly (SASA) that will be attached to the Integrated Truss Structure (ITS) Z1 on the International Space Station. The SASA antenna is primarily for local communications between the orbiter and Space Station.

The Z1 is scheduled on mission STS-92, the fifth flight to the Space Station, in the fall
