LEO天体扰动的聚集效应及其对噪声中天文数据丢失的影响
Aggregate Effects of Proliferating LEO Objects and Implications for Astronomical Data Lost in the Noise
摘要：
低空轨道上的人造地球卫星和相关碎片数量不断增加，增加了夜空的整体亮度，威胁到地面天文学以及依赖黑暗天空的各种利益攸关方和生态系统。我们目前的计算潜在的大幅度上升，全球天空亮度从空间物体，包括定性和定量评估如何专业天文学可能受到影响。碎片扩散特别令人关切：由于碎片大小的所有对数十年贡献的夜空辐射量大致相同，预计产生碎片的事件将导致夜空亮度迅速上升，同时厘米大小的物体对卫星造成严重的碰撞风险。这将导致天文数据的丢失，并减少地面发现的机会，因为微弱的天体物理信号越来越多地消失在噪音中。最后，我们讨论了更明亮的天空对一系列天空选区的更广泛的影响，地球和空间科学的公平性/包容性和可访问性，以及文化天空传统。太空和黑暗的天空是一种无形的遗产，值得为子孙后代有意保存和保护。
英文摘要：
The rising population of artificial satellites and associated debris in low-altitude orbits is increasing the overall brightness of the night sky, threatening ground-based astronomy as well as a diversity of stakeholders and ecosystems reliant on dark skies. We present calculations of the potentially large rise in global sky brightness from space objects, including qualitative and quantitative assessments of how professional astronomy may be affected. Debris proliferation is of special concern: since all log-decades in debris size contribute approximately the same amount of night sky radiance, debris-generating events are expected to lead to a rapid rise in night sky brightness along with serious collision risks for satellites from centimetre-sized objects. This will lead to loss of astronomical data and diminish opportunities for ground-based discoveries as faint astrophysical signals become increasingly lost in the noise. Lastly, we discuss the broader consequences of brighter skies for a range of sky constituencies, equity/inclusion and accessibility for Earth- and space-based science, and cultural sky traditions. Space and dark skies represent an intangible heritage that deserves intentional preservation and safeguarding for future generations.
