초록

최근 초소형위성, 소형위성에 대한 혁신적인 기술 발전으로 인해 거대 군집임무(Mega Constellation)가 활발하게 이루어지고, 재활용 우주발사체로 인한 우주 접근 비용이 급격하게 낮아지면서, 우주 개발은 지금까지와는 다른 'New Space Age' 시대로의 전환을 앞두고 있다. 이에 따라, 활발한 우주 개발의 필연적인 부수물인 '우주쓰레기'들의 증가로 인한 우주환경 악화 문제 역시 국제적인 관심사로 떠오르고 있다. 본 논문에서는 국가 우주정책의 변화를 앞두고 우주환경 보호를 위한 국제기구들과 각 국가들의 '우주쓰레기 경감 가이드라인' 제정 내용과 동향들을 살펴보고, 국제 사회의 향후 움직임에 대해 전망하였다. 또한, 우리나라의 현실에 맞는 가이드라인 예시 및 적용 방안에 대해서도 제안하였다.

With the recent breakthrough in technology for micro-satellite, small satellite, and mega constellation missions, and the cost of accessing space from recycled space launch vehicles sharply lowered. Thus, space development is set to make a transition to a new space age that is different from before. Accordingly, the problem of worsening space environment conditions due to the increase in space debris, an inevitable adjunct to active space development, is also emerging as an international concern. In this paper, the contents and trends of international organizations for the protection of the space environment and space debris mitigation guidelines of each country were reviewed and forecast the future movement of the international community. In addition, it is suggested example of guidelines that fit the reality of Korea and how to apply them.
