Keywords:Lunar Surface Science, Feasibility Study

The Artemis program, which aims to land humans on the Moon again, is currently progressing with the successful Artemis 1 mission launched on November 16, 2022 on the SLS-1 rocket. Japan declared its participation in the Artemis program in October 2019 and is expected to contribute to international lunar exploration by providing equipment for the Gateway habitation module, cargo spacecraft, and pressurized manned rovers, which are being studied primarily by JAXA Space Exploration Center (JSEC).

On the other hand, lunar surface is also a place where world-class scientific outcomes are expected to be achieved. Considering this, a top-down strategy was presented aiming to create world-class scientific results by taking advantage of the expanded opportunities for Japan's lunar activities through participation in the Artemis program. Based on this strategy, JSEC requested feasibility study proposals on lunar surface science in 2021. Fortunately, our team's proposal was selected, and we began a one-year study in the spring of 2022.

In the study, expected scientific results were reviewed and organized, and technological demonstration scenarios were discussed. Also, the configuration of science instruments and necessary resources for LEAD (Lunar Exploration Augmentation and Demonstration) mission, Japan's unique opportunity to land on the Moon, were studied. The presentation will include a summary of the feasibility study activities and results of the study.
