The paper describes the design specifics of the system for oxygen generation by electrolysis Elektron and major results obtained in long-term operation of the system aboard space station Mir. Operational data analysis makes possible to draw a conclusion that the system is capable to attain life parameters for at least 2 years with maintaining serviceability for no less than 8 years without attendance and unit replacement. Based on flight operation the possibility of reducing power consumption by 10 per cent is proven. System design updates are realized in the water electrolysis system intended for the Russian segment of the international space station.

Calibration analysis results for water solution samples of individual compounds, typical of spacecraft atmospheric humidity condensate, and their mixtures are provided. Comparison of the test results to the calculated data and laboratory analyses performed by other methods are made. Analyzer readings are in good agreement with the chemical analyses of initial condensate and recovered water. The analyzer shows promise as an instrument for ground and future onboard spacecraft testing.

At the initial phase of the construction of the international space station (ISS) water supply will be provided by the systems located in the Russian segment. The paper reviews the systems for water recovery from humidity condensate and urine to be incorporated in the Russian segment of the ISS. The similar systems have been successfully operated on the Mir space station. The updates aim at enhancing system cost-effectiveness and reliability. The system for water recovery from humidity condensate (WRS-C) features an added assembly for the removal of organic contaminants to be catalytically oxidized in an air/liquid flow at ambient temperature and pressure. The system for water reclamation from urine (WRS-U) incorporates a new distillation subsystem based on vacuum distillation with a multistage rotary distiller and a vapor compression or thermoelectric heat pump. The updating of the WRS-C system will enable an increase in the multifiltration bed's life at least two fold.

A concept of LSS building for planetary stations is suggested on the basis of experience in the development, research and testing of physical/chemical regenerative LSS for long-duration ground-based bio-technical complexes of habitat support and for orbiting space stations. A gradual transition from integrated physical/chemical regenerative LSS to hybrid integrated physical/chemical and bio-technical LSS and finally to integrated bio-technical regenerative LSS, is suggested. It is shown that at all phases of integrated LSS development, the systems based on physical/chemical processes will be critical for correlating the interfaces between the biological components that process the products obtained in the bio-components, and enabling the vitality of integrated LSS under emergency situations. The interface of integrated LSS with base power supply system is outlined.
