Elements: Z1 Integrated Truss Structure
The Z1 Truss
was the first permanent latticework structure for the space station,
very much like a girder, setting the stage for the future addition
of the station's major trusses or backbones. The Z1 fixture also
serves as the platform on which the huge U.S. solar arrays were
mounted on the following shuttle assembly flight, STS-97.
It includes power distribution components, four flat discs that
will be used to control the station's attitude, communications equipment,
temperature control system hardware, space walk/extravehicular aids
and power, data and coolant connections.
The crew of
shuttle mission STS-92 attached
the Z1 Truss to the station on Oct. 14, 2000.
