Near-Future Reusable Space Logistics Vehicles

Abstract

Key elements of the needed near-future, integrated, spacefaring logistics infrastructure are space-based, fully-reusable space logistics vehicles to provide transportation for passengers and cargo. This paper addresses the conceptual design of two such reusable spaceships using near-term technologies. The first is a space tug designed to support logistics operations in Low Earth Orbit (LEO). This space tug is sized to provide materiel handling, cargo transport, and passenger transport capabilities to support the construction and operation of orbiting logistics facilities and large spaceships. The second is a space ferry designed to transport cargo and passengers throughout the Earth-Moon system. This paper defines the assumptions and mission requirements used in the conceptual design of these two spaceships, summarizes the required Delta-V and maneuvering capabilities, assesses the technology maturity of the enabling technologies, summarizes the mass property estimates, provides illustrations of the conceptual designs, and provides examples of their use and integration into a near-future, integrated, spacefaring logistics infrastructure. The intent of this paper is to describe how current technologies can enable "aircraft-like" safe and routine transport of passengers and cargo within the Earth-Moon system.
