Abstract

This paper explores the concept of space sustainability and its interconnections using systems thinking approaches. This is done by highlighting the importance of multi-disciplinary perspectives when creating policies aimed at addressing the complex challenges of sustainability for space-related activities. Causal loop diagrams are employed to highlight the presence of feedback loops and causal relationships that are typically absent in space debris models and are treated as separate systems. A systems representation of the space environment is presented along with a discussion of its role in furthering research relating to the impact of large satellite constellations on factors important for holistic sustainability. This study investigated one example feedback between the space environment and the atmosphere and found that CO₂ emissions specifically emitted from launches and re-entries have no significant impact on atmospheric density below 500 km.

通过空间碎片管理实现空间可持续性的整体系统思维方法

本文利用系统思维方法探讨空间可持续性概念及其相互联系。在制定旨在应对空间相关活动可持续性复杂挑战的政策时，本文强调了多学科视角的重要性。采用因果循环图来强调反馈循环和因果关系的存在，空间碎片模型中通常不存在这些反馈循环和因果关系，而是将其作为单独的系统处理。本研究介绍了空间环境的系统表示法，并讨论了该表示法在进一步研究大型卫星群对整体可持续性重要因素的影响方面的作用。这项研究调查了空间环境与大气层之间的一个反馈实例，发现专门从发射和再入大气层排放的二氧化碳对 500 公里以下的大气密度没有重大影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
