ITS-S0 (Integrated Truss Structure S0) is the back-bone element of the International Space Stations main truss structure.
The Integrated Truss Structure of the ISS consists of a linearly arranged sequence of connected trusses which is used to mount various unpressurized components, such as ELC logistics carriers, radiators, solar arrays, and other equipment.
The S0 truss was attached on the top of the Destiny Laboratory Module during STS-110 in April 2002, where it is connected with four Module-to-Truss-Structure (MTS) struts on the top of the Lab (Destiny) module. S0 is used to route power to the pressurized station modules and conduct heat away from the modules to the S1 and P1 trusses, which carry the thermal radiators of the station.
