At present, the work of spacecraft flight control is in the downstream stage of the whole mission chain, and the flight control work mode cannot adapt to the subsequent space missions. In response to these limitations, a conceptual design of a work mode for space flight control from the metaverse’ s perspective is proposed. Model-based systems engineering (MBSE) is adopted as the basic methodology for constructing the flight control metaverse. A common flight control infrastructure is proposed as the foundation for mission system development. A flight control metaverse architecture that targets missions throughout the flight control process is built with extensive applications of AI technology. A new flight control work mode and a mission system work mode are designed to bring about systemic innovation in the flight control work mode. The former work mode features a model-based design of flight control schemes, agile and automatic implementation of mission systems, integrated flight control mission implementation, and parallel operation in physical and virtual spaces. The latter work mode comes with intelligent control, flexible deployment, and autonomous operation capabilities. The flight control metaverse presents a new mode of working space for flight control. The new flight control work mode that builds on the flight control metaverse can be used as a technical reference for the continuous innovation and improvement of subsequent flight control practices.
