This is the first level of a three-level standard defining a human spaceflight (HSF) spacecraft ontology from architectural and system engineering viewpoints. It provides guidance for systems and architecture design emphasizing human-system integration (HSI) requirements and constraints. While adopting a holistic approach, this complex domain is stratified using a three-dimensional roadmap (lifecycle, function, location) that guides the user to a high-level, fundamental, and context-specific design requirement based on the HSF program, mission and spacecraft goals.
