This study investigates the usage of a system model as a means to capture concept formulation for a potential mission. Efforts are underway at JPL to explore the architectural and system concepts for a lander on Europa. Executing a mission on the surface of Europa poses unique challenges that will require the lander to operate with onboard autonomy that is more sophisticated than systems previously operated by JPL. Current tasks to explore surface mission concepts intend to identify concepts that enable a high degree of onboard autonomy as well as identify the issues and technical limitations that restrict autonomy. The Europa lander mission concept team is developing a system model to support this exploration. The results of this study highlight how executable system modeling and the associated engineering environment may be applied to pre-project conceptual exploration. The application of system modeling has resulted in a central system model that precisely describes the concepts formulated by the Europa Lander Mission Concept Team. Documentation in the form of diagrams and narrative has been directly generated from the system model and accessible by team members in a web application. The executability of the system model enables various analyses such as simulation of interactions between components and evaluating system behavior against requirements. Execution of the system model has produced state timelines, plots of system variables, and simulation traces based on input scenarios. The executable system model enables the rapid and repeatable production of these artifacts.
