The paper discusses the current status of work to extend the life of the International Space Station Russian Segment (ISS RS). The effort to monitor and maintain the ISS RS systems and modules in good working order forms the basis of the work aimed at station longevity and the safety of its crew. It describes measures taken to keep the ISS RS operational in a situation where some of the components have been taken out of production, and specified storage life for the spares, tools and accessories has expired. It reviews changes in the requirements for the operation of constituent components, systems and assemblies that were adopted to support extension of the ISS RS mission. It describes a procedure for detecting the sources of failures and malfunctions found in flight and resolving their causes, which makes it possible to take measures aimed at preventing propagation of faults and malfunctions within the shortest time possible while keeping the systems and assemblies of the ISS RS modules operational during repairs. It describes an approach to analysis of the causes of component failures, which makes it possible to classify them for the purposes of statistical analysis, on the basis of which one could evaluate failure dynamics in the course of the mission and use it for making a conclusion about the feasibility of extending flight tests of the ISS RS till 2024 and further. It provides data on dynamics of changes in the number of component failures in the course of the ISS RS mission, which show that this number does not grow.
