Abstract

The increasing launch rate of spacecraft, particularly due to the deployment of large constellations and miniaturized satellites in Low Earth Orbit (LEO), has led to a significant rise in space traffic and debris. This paper examines emerging technologies and strategies for future Space Traffic Management (STM) to ensure sustainable operations in space. Key focus areas include the use of artificial intelligence (AI) for enhanced Collision Avoidance (CA) systems, the development of advanced Space Surveillance and Tracking (SST) capabilities, and Active Debris Removal (ADR) techniques to mitigate the growing risks associated with space debris. Additionally, the paper explores the potential of in-orbit servicing, re-entry services, and the exploitation of Very Low Earth Orbits (VLEO) and cislunar space. The integration of these technologies and practices is essential to manage the anticipated growth in space activities while minimizing collision risks and ensuring the long-term sustainability of the space environment.

面对日益增长的空间交通，未来的近地空间活动

航天器的发射率不断提高，特别是由于在低地球轨道（LEO）部署大型星座和小型化卫星，导致空间交通和碎片显著增加。本文探讨了未来空间交通管理（STM）的新兴技术和战略，以确保空间的可持续运行。重点领域包括利用人工智能（AI）增强避免碰撞（CA）系统、开发先进的空间监视和跟踪（SST）能力，以及采用主动碎片清除（ADR）技术来降低与空间碎片相关的日益增长的风险。此外，本文还探讨了在轨服务、重返服务以及利用甚低地球轨道（VLEO）和半月空间的潜力。这些技术和做法的整合对于管理空间活动的预期增长，同时最大限度地降低碰撞风险和确保空间环境的长期可持续性至关重要。
