Mission design is the process of planning and strategizing the objectives, requirements, and parameters of a space mission. This includes determining the goals of the mission, selecting the appropriate spacecraft and instruments, designing the trajectory and flight path, and calculating the necessary propulsion and navigation maneuvers. Mission design also involves considering factors such as launch vehicle capabilities, cost constraints, and operational limitations in order to ensure the success of the mission. The ultimate goal of mission design is to effectively and efficiently achieve the scientific or exploration objectives of the mission.
