Oxygen From Regolith (O2fR) Collaborative Systems Interface Study Path Forward

The "Oxygen from Regolith (O2fR) Collaborative Systems Interface Study" explores strategies for managing interactions at system interfaces of lunar in-situ resource utilization (ISRU) technologies. Last year, the Lunar Surface Innovation Consortium (LSIC) ISRU Capability Area (CA) introduced the O2fR Collaborative Systems Interface Workbook, including a Design Structure Matrix (DSM) and Interface Worksheets. The workbook provides a framework to help the ISRU community identify quantitative mismatches between upstream and downstream system parameters as well as map dependencies such as energy, mass, and information flows across ISRU functions. On September 18, 2024 the LSIC ISRU CA held the Collaborative Systems Interface Workshop, where the participants explored how concepts in the workbook can influence their interface design and encourage smooth system integration to support NASA’s lunar sustainability goals. Insights from the workshop and feedback from the community have influenced the LSIC ISRU CA’s planned activities in the year ahead. The path forward for the O2fR Study includes maintaining a database of interface parameters on Confluence and providing opportunities to facilitate application of the workbook to the ISRU systems.
