Water Electrolysis Propulsion as a Case Study in Resource-Based Spacecraft Architecture (February 2020) [link]Paper  doi  abstract   bibtex   
In situ resource utilization (ISRU), the use of materials available on-site to replenish supplies or manufacture components during a mission, is vital to sustaining human presence in space. ISRU has been identified by NASA as one of the key technologies in the Human Exploration Destination Systems Technology Area. In recent years, the abundance of water in the solar system has been made increasingly clear. Extraterrestrial water, liquid water especially, is of great scientific interest, as targets where water is available are often desirable for future exploration. ISRU with water is therefore a particularly high priority. This paper considers the implications of in situ water on the design of space systems, with the use of water for multiple purposes on the CisLunar Explorers EM-1 secondary payload as a case study. Water onboard the CisLunar Explorers is used in every subsystem: as propellant, for slosh-damping, as a heat sink, and as a radiation shield. The CisLunar Explorers spacecraft do not collect water in situ but, instead, serve as a pathfinder for demonstrating the utility and versatility of water for future ISRU.
