								By considering the characteristics of space science satellite projects, this paper studies budget management problems of space science projects. Taking the X Satellite Project as an example, this paper firstly analyzes the flaws of current budget and cost control methods. Then, some possible solutions are proposed by establishing an improved project cost control framework, which optimizes the current mission management system by introducing options such as combination of leading cadre, new budget management and cost control systems.
