The lunar scientific research station is one of the key aerospace undertakings in my country at present, and it is very important for my country to win the future space race. At present, there is a blank in the field of lunar scientific research stations at home and abroad. The biggest challenge of its performance is that there are no cases and experiences for reference. The key point is that it needs to use the forward design concept in line with my country"s spacecraft development and a complete system engineering task analysis process. . In view of this, this paper adopts the idea of Model Based System Engineering (MBSE, Model Based System Engineering), and proposes a suitable model-based forward process for the system analysis of the lunar scientific research station, and uses the system model as a carrier to analyze the overall analysis of the mission and the mission requirements in turn. Analysis and task application scenario analysis. By carrying out the model-based mission analysis of the lunar scientific research station, the process of the mission analysis of the lunar scientific research station has been preliminarily realized. Development requires activation.
