In this paper, a method to analyze and optimize the cost of on-orbit refueling mission is proposed and developed. On-orbit refueling optimization framework which aims to minimize service cost of spacecraft is established. In order to analyze the best on-orbit refueling strategy, cost models of both disposable and reusable spacecraft that could offer propellant-loading operation are built up and cost elements are classified on basis of spacecraft cost model. Numerical results show that the

According to optimization, the refueling period of reusable spacecraft is shorter than the disposable one and the total cost is lower. Also, the cost of reusable spacecraft, closely related to the development of technology, plays the most important role in the overall cost of on-orbit refueling mission.
