Technical strategies for lunar manufacturing

Abstract Several strategies for developing lunar manufacturing are discussed and evaluated. A semi-self-sufficient, or controlled, manufacturing system on the Moon is proposed and its evolutional scenario is studied. It is found that the demands for lunar base repair and expansion, lunar liquefied oxygen pilot plant and solar collectors made from lunar iron and ceramics can be appropriately combined to create an evolving system of lunar manufacturing, which will be a sufficient driver for lunar development.

Unmanned in situ experiment on lunar resources

Abstract A robotic experiment on lunar materials in the context of lunar base and lunar resources utilization is designed. A mobile robotic laboratory is sent to the lunar surface by an H-2 rocket to perform exploration for resources and experimental processing/handling of the surface materials.

Space escalator, semi-perpetual motion in space☆

Abstract A novel orbital transfer system using the mutual action-reaction of two spacecraft as the main propulsive force is proposed. A set of space platforms which are deployed on circular orbits of various altitude and have mobility to transfer to other orbits by themselves can work on a very little propellant.
