Fly me to the Moon ‐ Modeling Apollo 11 Using SysML v2

ABSTRACT

The finalization of Systems Modeling Language Version 2 (SysML v2) represents a significant advancement for Model‐based Systems Engineering (MBSE), offering a formal textual syntax and enhanced semantic precision to manage the complexity of modern systems. However, the practical utility of a new language can only be validated through rigorous application to non‐trivial problems. This paper addresses the current scarcity of large‐scale, public SysML v2 models by presenting a comprehensive model of the Apollo 11 mission. Using the five‐layer CoSMA framework as a structuring guide, we created a detailed, multi‐layered representation of this historically significant and complex system. This effort delivers two primary contributions: first, a rigorous evaluation of the expressive power and features of SysML v2 against a real‐world case study; and second, the provision of a foundational, open‐source artifact for the systems engineering community. The resulting model demonstrates the language's strengths in creating traceable, integrated, and verifiable system specifications. The complete Apollo 11 model is released publicly to serve as a common reference point, an educational resource, and a benchmark for the development of next‐generation MBSE tools, thereby accelerating the adoption and maturation of SysML v2.
