The objective of this document is to explore the design of a simulative analog of a space habitat, intended as a platform for testing and validating various technologies to advance knowledge in human space exploration. The design process follows the ARCADIA, Architecture Analysis and Design Integrated model-based Approach, which, in recent years, has proven to provide a clear, precise, and fast way to manage and modify projects. This model-based approach is implemented using the modeling software CAPELLA™. Following a comprehensive analysis of the working context, the project begins with a theoretical phase, during which objectives, functions, and corresponding components are defined.
