ISS Integrated Truss Structure

The Integrated Truss Structure (ITS) of the International Space Station (ISS) consists of a linearly arranged sequence of connected trusses on which various unpressurized components are mounted, such as logistics carriers, radiators, solar arrays, and other equipment. It supplies the ISS with a bus architecture. All truss components were named after their planned end-positions: Z for zenith, S for starboard …

International Space Station – ISS

The International Space Station (ISS) is a habitable artificial satellite in low Earth orbit. It is the largest artificial body in orbit and can be seen with naked eye from Earth. The ISS consists of pressurized modules, external trusses, solar arrays, and other components. ISS components have been launched by American Space Shuttle missions, and Russian Proton and Soyuz rockets. …

ISS External Stowage Platform

External stowage platforms (ESPs) are key components of the International Space Station (ISS). Each platform is an external pallet that can hold spare parts, also known as Orbital Replacement Units (ORUs), for the space station. As a platform it is not pressurized, but does require electricity to power the heaters of some of the stored equipment. ORUs are attached to …

ISS Tranquility Module (Node 3)

Tranquility, also known as Node 3, is a module of the International Space Station (ISS). ESA and the Italian Space Agency had Tranquility built by Thales Alenia Space. A ceremony on November 20, 2009 transferred ownership of the module to NASA. The module provides six berthing locations, but three of those locations are disabled, as modules originally planned to be …

ISS Unity Module (Node 1)

The Unity connecting module was the first U.S.-built component of the International Space Station. It is cylindrical in shape, with six berthing locations (forward, aft, port, starboard, zenith, and nadir) facilitating connections to other modules. Sometimes referred to as Node 1, Unity was the first of the three connecting modules; the other two are Harmony and Tranquility.
