STS-92 was an ISS assembly flight that brought theZ1 truss, Control Moment Gyros,Pressurized Mating Adapter-3 (PMA-3) (mounted on aSpacelab pallet) and two DDCU (Heat pipes) to thespace station.[1][20]TheZ1 truss was the firstexterior framework installed on the ISS and allowed the first U.S. solar arrays to be temporarily installed onUnity for early power during flight 4A. The Ku-band communication system supported early science capabilities and U.S. television on flight 6A. The CMGs (Control Moment Gyros) weigh about 27 kilograms (60 lb) and provide non-propulsive (electrically powered) attitude control when activated on flight 5A, and PMA-3 provides shuttle docking port for solar array installation on flight 4A andDestiny Lab installation on flight 5A.
The mission included seven days of docked operations with thespace station, fourEVAs, and two ingress opportunities.
Over the course of four scheduledspacewalks, two teams ofspace walkers and an experiencedrobot arm operator collaborated to install theZ1 (Z for zenith port) truss structure on top of theU.S.Unity connecting node on the growing station and to deliver the third Pressurized Mating Adapter (PMA 3) to theISS for the future berthing of new station components and to accommodate shuttle dockings.
TheZ1 truss was the first permanent lattice-work structure for the ISS, very much like a girder, setting the stage for the future addition of the station's majortrusses or backbones. The Z1 fixture also served as the platform on which the huge U.S.solar arrays were mounted on the next shuttle assembly flight,STS-97. The Z1 truss included many elements of theCommunications and Tracking subsystem. Thehardware included aTransmitter/Receiver/Controller (SGTRC) built by L3 Communications Systems-East inCamden, NJ. John Schina was the Chief Engineer of theISS Program at L3.
The Z1 contains four largegyroscopic devices, calledControl Moment Gyroscope (CMGs), which are used to maneuver thespace station into the proper orientation onorbit once they were activated following the installation of theU.S.laboratory.
During the fourthspacewalk, astronautsWisoff andLópez-Alegría tested theSAFERjet backpack, flying up to 50feet while remainingtethered to thespacecraft.[13]
