The Columbus Man-Tended Free Flyer (MTFF) thermal control system (TCS) is described. The redundancy philosophy for TCS is discussed and the resulting thermal control concept presented. Effects of the failure tolerance requirements on the overall MTFF thermal control architecture as well as the arrangement of subsystem units within the MTFF for thermal control reasons is considered. Reliability analyses are outlined. For operating the MTFF at a required reliability level of 0.93 for nominal payload support for 180 days, the items aboard are classified in three criticality categories. Therefore various required failure tolerances have to be provided by an appropriate redundancy concept for each of these criticality categories.
