Future extended duration space missions will benefit from conservation and recovery of vehicle and crew waste products to reduce resupply expenditures. Reclamation of potable water from urine humidity condensate, and wash water is the single most significant candidate for recovery. The Thermoelectrically Integrated Membrane Evaporator Subsystem (TIMES) distillation water recovery concept utilizing hollow fiber membranes for phase separation and thermoelectric heat pumps for latent heat recovery brings unique advantages to meet the challenge of reliable, efficient, zero gravity water recovery. The TIMES concept limits presision moving parts to valves and pumps leaving small, lightweight static parts for the evaporation and condensation modules. The many varied applications of the TIMES, e.g., Extended Duration Orbiter, space 'Construction Shacks', free-flying space labs, and Space Station will benefit from the modularity of the concept. The paper discusses the optimization and application of the TIMES concept and the benefit of the concepts's modularity to these aspects. Further vehicular and other subsystem integration flexibility of the TIMES concept are presented. (Peters)
