Definition

An on-orbit refueling facility built on a lunar distant retrograde orbit (DRO), receiving transport vehicles from LEO service stations for propellant transfer. In this paper, it orbits with a period equal to half the lunar orbital period, with a 2-day docking duration. In the airline-flight-mode cislunar transport architecture, the DRO service station is a key node in the Earth-Moon supply chain, supporting lunar base construction and deep-space missions.

Application Value

This concept has important application value in cislunar space research and mission design.
