Long-duration space mission regenerative life support.

The paper deals with the construction of physical/chemical life support systems of orbiting space station Mir and the Russian segment of the international space station (ISS). Based on experience gained in development and long-term operation of systems for water recovery and air revitalization balance and energy/mass characteristics of promising life support systems (LSS) are analyzed. Physical/chemical life support systems with regenerative systems updated as a result of the operation on the ISS may be used at an initial phase of manned interplanetary missions.
