Orbital Sustainability: Perspectives and Solutions for Space Debris Challenges

Introduction

In this bibliography, I will delve into "Space Debris Management" (SDM). It examines methods and technologies for dealing with accumulated space debris, including decommissioned satellites, rocket platforms, and other objects suspended in Earth orbit since the beginning of space exploration in the 1950s. In the 19th century, humanity has left behind debris in space. The debris has accumulated extensively over the decades, posing major challenges for future space efforts. The historical context reveals how our activities in space have led to the current tragedy of environmental aggression.

Space debris management is an important issue to focus on because of its impact on future space missions and satellite operations. The propagation of space debris increases the risk of collisions, causing serious hazards such as the destruction of operational satellites and spacecraft. The motivating question behind this research is how space activities contribute to sustainability and impact vital industries reliant on space-based technologies like telecommunications, navigation, and weather forecasting. Which all are currently used for space debris mitigation and disposal, and how effective are they?" This inquiry aims to uncover the existing approaches employed to address the challenge of space debris accumulation and evaluate their efficacy in mitigating the risks posed by orbital debris.

In this article, Darren McKnight, a senior technical fellow at LeoLabs, alongside Chris Kunstadter, global head of space at AXA XL, explores the critical need for Space Debris Management (SDM) over Space Traffic Management (STM). The authors argue that while STM is essential for avoiding immediate collisions, SDM addresses the root cause by focusing on the removal and mitigation of existing space debris. The piece highlights how the increasing population of operational satellites and the consequent risk of collisions demand a more proactive approach. Notably, McKnight and Kunstadter emphasize the significance of international cooperation, citing a specific analysis that points to a high-risk region between 775 and 850 kilometers in low Earth orbit crowded with derelict Russian rocket bodies and fragments from various countries. They advocate for a joint remediation mission involving key space agencies like NASA, Roscosmos, and CNSA to remove the most dangerous objects, showcasing the potential for collaborative efforts in reducing collision risks. This source provides valuable insight into the complexities of space debris management, underlining the role of international partnerships and advanced debris removal technologies in ensuring the long-term sustainability of space operations. This article is significant for my research as it outlines a clear and actionable strategy for addressing the space debris issue, underscoring the urgency and importance of global cooperation and technological solutions. It presents a balanced view, recognizing the efforts in STM but highlighting SDM as a critical next step. The analysis within the article forms a basis for understanding the potential efficacy of active debris removal (ADR) initiatives and sets a precedent for international collaboration in space sustainability efforts.
