ISS Assembly Mission 3A
ISS Assembly Mission 3A

Arriving aboard Space Shuttle Discovery, the STS-92 crew installed the Z1-Truss. Inside the Z1 are four Control Moment Gyroscopes (CMGs) that provide the International Space Station's attitude control. The CMGs were later activated on ISS Assembly Mission 5A. A third pressurized mating adapter was installed on the Unity Node, providing an additional Shuttle docking port. A Ku-band antenna provides television capability.
