The increasing number of space missions and the market environment make it mandatory that the design process and design models have to be reused in future space missions. As a solution to such a reuse problem, Model-Based Systems Engineering (MBSE) is highly recommended. Since constructing a model is the first step to reach MBSE, a 3D state decomposition modeling method is proposed in this paper. Starting from Technical Requirements (TRs), the method maps them to state variables and defines states as well as relations along three red lines of space engineering: internal subsystem, inter-subsystems, and space mission lifecycle. Eventually, it yields decomposition of a space system into a hierarchical three-dimensional model of states. Relying on the Eclipse Modeling Framework (EMF), the model can be described and stored in a standardized format, which allows the reuse of once defined models in subsequent space missions. This study leads to a novel MBSE solution to implement specification, analysis, design, and operation of space mission systems in a unified framework.
