Abstract
In-Space Manufacturing (ISM) represents a pivotal shift in the paradigm of space exploration and the exploitation of extraterrestrial environments. This paper introduces a model-based conceptual approach to the design of the Enhanced Factory for Extraterrestrial Space Technology Operations (EFESTO) system. Leveraging Model-Based Systems Engineering (MBSE) to integrate simulations and virtual testing, the architecture aims to support in the refinement of ISM systems throughout its entire development process, from conception to realization. With the advent of ISM as a cornerstone for future space missions, this study leverages MBSE to systematize the conceptual design of ISM systems, meeting the intricate demands of space environments. In particular, this work will explore how the MBSE approach can be used to investigate operational, economic, and legal aspects to assess the market viability of ISM, intending to meet the rigorous technical and safety standards of ISM, while also considering the commercial imperatives that will shape future human space activities. MBSE's rigor in the conceptual phase is the focal motivation, intending to reinforce the technical base for ISM systems that are both robust and adaptable.
