Shuttle Tethered Satellite System Program Overview

The first of two demonstration flights of the tethered satellite system (TSS) is planned for the STS-52 flight and is designed to study tether electromagnetic interaction. The magnetospheric-ionospheric-atmospheric coupling processes in the lower troposphere are to be directly measured on the second TSS mission. An operational overview of the TSS-to-orbiter-to-ground interface is given and the TSS deployment concept is explained. Other aspects discussed include the tethered satellite-to-orbiter interface; tether control mechanisms; tether materials, and electrical interfaces. The design of the demonstration flight satellite and its instruments is described. The capabilities of the TSS for the demonstration flight are listed.
