Building the International Space Station: Five Years in Orbit

Truss-ing up the ISS

Launched aboard Space Shuttle Discovery on Oct. 11, 2000, the STS-92 astronauts installed the Z1-Truss at the International Space Station (ISS). Inside the Z1 are four Control Moment Gyroscopes (CMGs) that provide the International Space Station's attitude control. A third pressurized mating adapter was installed on the Unity Node, providing an additional Shuttle docking port. A Ku-band antenna provides television capability. Click to enlarge.
