Crew life support system concept for interplanetary missions

The article defines the composition of the systems providing the regeneration of water and oxygen from the life products of the crew in a closed physico-chemical complex of the life support system of interplanetary space expeditions. It is a complex with modernized systems for the regeneration of water from all possible sources, with dehydrated diets, a system for the regeneration of oxygen from carbon dioxide based on the electrolysis of carbon dioxide to produce oxygen and carbon monoxide with its subsequent hydrogenation to water and methane, and with the inclusion of biological units. Such a complex can be created as a base on the basis of upgrading the life support systems of the Mir stations and the ISS for both lunar and interplanetary flights, as well as for flights in Earth orbit. At the same time, the cargo traffic to the manned orbital station significantly decreases the resource elements of the systems and products for the crew. The article presents the schemes and parameters of the main projected regeneration systems and the base complex as a whole, as well as the mass-energy summary of the complex.
