한국형 달 복제토의 핵심 요소 개발을 위한 실험적 연구

Abstract

Recently, interests on space exploration and development are increasing. From recent NASA's experiments, scientists found that water is existed on the moon. This should be meaningful to long-term man existing on the moon. And, for the near future, colonization of Mar will be realized. Moreover, for human living on the moon and Mars, space construction activities will be the key technology. To understand space environments, study on lunar soils should be executed. However, unlike other countries, space researches in Korea are mostly focusing on satellite, launcher and satellite application technologies. Korea does not make plans to explore or build on the moon so far. But, Space construction is the most important area for future space activities. Since Apollo projects, only 380kg of lunar soils were collected, and this amount is not enough to perform the space development projects. So, many space agencies try to simulate the lunar soil. As a result, this study is working on developing key elements that have to be added in Korea lunar simulant by using basalts in Korea as a testbed. Study on adding glass property, agglutinate or other property to simulant lunar simulant will be executed. Moreover, mechanical properties including shear strength, density and other values will be measured. Also, this study will research on developing the lunar simulant having forms of agglutinate as key elements. From this study, formation of an agglutinate will be examined, and glass property will be added in the simulant. Finally, this study will provide feedstock for space exploration activities. With lunar simulant developed from this study, equipment tests in lunar environment will be available. Furthermore, Korean lunar concrete, lunar construction material, anchoring system and other lunar material can be developed and tested by using Korean lunar simulant experimented in this study.
