space science mission concurrent design is to meet the scientific mission requirements, optimize the spacecraft design and ultimately reaches a feasible solution for the proposed program. The information management system for space science mission concurrent design is developed to manage all design disciplinary data and support data exchange between the coupled disciplines. The space science mission concurrent design process and information involved are reviewed and analyzed. The system architecture is divided into three layers, including the data persistence layer, business logic layer and presentation layers. Data persistence layer provides local data services, data entities access, data entities, file system. Business logic layer provides file management, workflow management and data exchange interface. Presentation layer provides interactive interface. A space science mission application is given as an example. The simulation results show the mission design can be performed via the information management system to acquire high quality results.
