The paper describes the thermal control and life support design and related system aspects of the COLUMBUS Free-Flyer.The specific requirements for the FreeFlyer thermal control and environmental control and life support are mainly driven During the Resource Module exchange at the Space Station Freedom the Pressurized Module is deactivated and thermally controlled by a heater system supplied with power by the space station. After attachment of the new Resource Module the internal servicing will be performed. During this phase the entire heat load of the Pressurized Module is transferred to the Space Station. During HERMES servicing and all free-flying phases the Free-Flyer thermal control is fully autonomous.The Free-Flyer Environmental Control and Life Support System (ECLSS) is also strongly affected by the interfaces to the Space Station Freedom and HERMES. Reductions in complexity, cost, mass and power have been achieved by centralizing particular ECLSS functions, during the servicing phases.
