Development of a Planetary Water Treatment System

Abstract

As NASA prepares for human missions beyond the International Space Station (ISS), NASA personnel have begun development of a water treatment system that is optimized for operation on the Moon and Mars. This system will take advantage of the partial gravity of surface-based habitats while minimizing resupply mass and ensuring optimum reliability. An overview of expected water uses, waste streams, and architectures for a partial gravity water recovery system (WRS) is presented and compared to the WRS on ISS. This paper summarizes the current progress of evaluating various technologies and architectures for the potential mission profiles currently being considered.
