Abstract

After industrialization has been started, mankind needs and consumes more resources. Now, the resources depletion is a serious problem in the Earth. However, there are infinite resources in the Space. Especially, the Moon is the closest planet and has much resources, including Helium-3 and rare earths, which are needed to human being in the future. Humanity needs to reside on the moon to harvest these resources. For the resident, much resources, such as food, construction, and industrial materials, are needed. However, to transport these resources to the Moon from the Earth, an astronomical cost should be consumed. Thus, research is underway to support human activities by procuring resources locally. This is called In-Situ Resources Utilization (ISRU), which is the essential technology for the space development. In this paper, the reason why ISRU is essential and the its status are introduced and future research projects will be explained.

산업화가 시작된 후 인류는 더 많은 자원을 필요로 하고 소비하며, 현재 자원 고갈은 지구의 심각한 문제이다. 그러나 우주에는 무한한 자원이 존재한다. 특히 달은 지구와 가장 가까운 행성으로 미래 인류에게 필요한 헬륨-3, 희토류 등 많은 자원을 보유하고 있다. 이러한 자원을 채굴하기 위해서는 인류가 달에 상주할 필요가 있다. 그리고 달에 거주하는 인류는 식량, 건축, 산업 자재 등 많은 자원이 필요하다. 그러나 이러한 자원을 지구에서 달까지 운반하려면 천문학적인 비용이 소모되므로 현지에서 자원을 조달하여 인류의 활동을 지원하는 연구가 진행되고 있다. 이를 ISRU(In-Situ Resources Utilization)라고 하며, 이는 우주개발에 필수적이다. 본 논문에서는 ISRU이 필수적인 이유와 그 기술현황을 소개하고 향후 연구과제에 대해 서술하였다.
