AbstractThe present research team in ISS project office, JAXA focuses the fundamental researches of in-situ Resources Utilization on Lunar Base. The targets are deeply linked with the activities in "Nano-meter Structured Materials Processing for Energy Devices for Space", which is regarded as the international topical team between ESA and JAXA, "Electrochemical Nucleation and Growth". It is developed from the accumulated information in the multi-disciplinary fields of Space Environment Utilization Science Field. The program is composed of three categories: (1)Depth Distributions of Lunar Regolith followed by Resources Exploration: Resources exploration survey based on the laser sounder data supplied from JAXA lunar satellite "Kaguya", subsequently followed by regolith transportation and separation engineering under 1/6 gravity, (2)Characterization of Lunar Regolith and Solar Wind Implantation Mechanism: The design of gaseous component recovery system with regolith stimulant and the clarification of solar wind implantation into finer oxide particles: (3)In-situ Resources Utilization on Lunar Base: O2(g) and light metal extraction by molten salt electrolysis as well as energy conversion and storage processesTo begin with the projects, "Depth Distributions of Lunar Regolith" must be carefully examined, because regolith composition considerably varied according to the samples in Apollo project. We adopt sophisticated seismic data processing methodologies into "Kaguya"'s laser data. Especially the migration analysis becomes a key processing and Kirchhoff migration. Then, regolith stimulant is exposed to H2 plasma to understand the absorption and desorption mechanism to clarify solar wind implantation mechanism. The transportation of lunar regolith simulant and the separation technique based on electrostatic and electromagnetic gradient field must be further designed. The third target is oxygen gas evolution as well as light metal production aimed at solar power generation. Molten salt electrolysis plays primarily an important role in such a non-equilibrium electrochemical processing. Three phase interfacial phenomena must be focused as well as the development of inert anode which can be applied to high temperature molten oxide. In the present paper, O2 gas evolution reaction is reasonably and successfully discussed on B doped diamond and ferrite anode. Computational chemistry is also an important tool as well as in-situ measurement technique based on Synchrotron Radiation Technology.
