The cislunar spaceport for the crew delivery to the lunar surface

Abstract

The success of the International Space Station project has inspired the partners to review possible steps in space exploration beyond Low Earth Orbit. The Moon, Mars, or asteroids - the priorities of partners’ national programs could be different. Understanding of the deep space exploration viability by the joint team led partners to consideration regarding Cis-Lunar Spaceport which will become a Spaceport and should facilitate the implementation of the national programs. At the present time a concept of the Spaceport located on high-elliptical lunar orbit is being widely discussed. The Spaceport is considered to be a transportation hub supporting deep space exploration programs: missions to the Moon, asteroids, Mars and other natural and artificial objects. Different schemes of crew delivery to the lunar surface using Lunar Lander based and serviced at the Spaceport are compared in the paper. The Spaceport utilization significantly reduces transportation operations time limits and provides conditions for reusable lunar spacecraft implementation. Key words: Cislunar spaceport, high-elliptical lunar orbit, ascent module, descant module, reusable lunar crew vehicle.
