ARC-Space aims to promote research in the field of space informatics, which integrates space science and informatics, through industry-academia collaboration, and to provide the results to the academic community, thereby contributing to the vitalization of research in the field and to the advancement of its technological development. ARC-Space was certified as a joint usage/research center for Lunar and Planetary Exploration Archive Science, by the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT) in FY2019. Lunar and planetary exploration archive science refers to a form of research in which new insights are obtained by combining data obtained and accumulated through past lunar and planetary exploration and observational research with the latest knowledge and analysis techniques. As one of the major activities of ARC-Space, we will be offering Joint Research Program for research carried out between researchers in the academic community and faculty members of ARC-Space. We will be accepting proposals in two categories; Exploratory Research, which is for preliminary stage of R&D, and Practical Research, which is for full-scale R&D including collaboration with industry. We will be calling for themes that promote the lunar and planetary exploration archive science and contribute to the community through, among other things, enhancing the value of lunar and planetary exploration data, the development/maintenance of analysis tools, and the provision of services. Applicants for this program may also apply for the Joint Research Program with Invited International Researchers and Overseas Travel Grants Program at the same time.
