Space traffic jam: Challenges facing space sustainability
from USSC Live · host The United States Studies Centre
Out of sight, out of mind. Low Earth Orbit has undeniably become busier, with upwards of 10,000 satellites and millions of pieces of space debris currently in orbit. With vital services—ranging from communications to climate monitoring, national defence, and financial services—increasingly reliant on space, the proliferation of space assets and debris, and the associated risks of collisions, explosions, and anti-satellite warfare have become a major political issue.Countries have developed new tools and cultivated norms to improve traffic management and space sustainability. However, amid a proliferation of space stakeholders; the absence of binding international agreements; and challenges in monitoring activities in space, significant gaps remain.How are public and private actors navigating the challenges of growing congestion in space? How can international frameworks like the Outer Space Treaty be strengthened to address these risks? And how can space sustainability be integrated into the national security policy debate?To address these questions, the United States Studies Centre was pleased to host a webinar with Audrey M. Schaffer. Ms Schaffer is an internationally recognised expert in space policy, currently serving as Vice President of Strategy and Policy at Slingshot Aerospace and Non-Resident Senior Associate with the Aerospace Security Project at the Center for Strategic and International Studies. She previously served in the US government for over 15 years, holding positions in the Executive Office of the President, Department of Defense, Department of State, and National Aeronautics and Space Administration (NASA). Ms Schaffer led the US delegation that negotiated the UN Guidelines for Space Sustainability and, from 2021–23, served as Director for Space Policy on the National Security Council of the Biden-Harris Administration.This webinar was hosted by Dr Kathryn Robison, Lecturer in American Studies at the United States Studies Centre and Senior Research Fellow at the Australian Centre for Space Governance.This event was made possible with funding from the US State Department.
