New Publication on Space Junk and Anti-Satellite Warfare

Senior Russian government officials have threated to destroy U.S. satellites.  See https://www.livemint.com/news/world/russia-threats-to-hit-us-satellites-if-it-continues-to-11666885278398.html; https://arstechnica.com/science/2022/10/russia-threatens-a-retaliatory-strike-against-us-commercial-satellites/;https://www.reuters.com/world/russia-says-wests-commercial-satellites-could-be-targets-2022-10-27/.

Also, this week, the International Space Station, yet again, has needed to change orbit to avoid a possible collision with Russian space debris.

am pleased to announce publication of a paper that explains how anti-satellite warfare and space junk make it more difficult for nations to agree on rules for sharing space and radio spectrum resources: 

See https://www.sciencedirect.com/journal/telecommunications-policy/vol/46/issue/10.

Here’s the abstract:

This paper explains why the coordination of satellite orbits and spectrum use among nations have become more contentious and less routine.  The potential for greater risks, delays, and conflicts occurs, despite treaty-level commitments to promote the peaceful uses of outer space and efficient and equitable access to radio spectrum and satellite orbits. Heretofore, specialized sectors of the United Nations (“UN”) have worked effectively in forging multilateral consensus on these matters.

The paper explains why the coordination of satellite orbits and spectrum use among nations may become more contentious and protracted. The potential for greater risks, delays, and conflicts may occur, despite treaty-level commitments by most nations to promote the peaceful uses of outer space and access to radio spectrum and satellite orbits free of signal interference and collision risk. Heretofore, specialized sectors of the United Nations (“UN”) have worked effectively in forging multilateral consensus on these matters.

Since the onset of artificial satellite technology, the UN has created five space-related treaties covering such issues such as freedom of exploration, liability for damage caused by space objects, the prevention of harmful interference with space activities and the environment, the notification and registration of space activities, exploitation of natural resources in outer space and the settlement of disputes. The International Telecommunication Union (“ITU”), a specialized agency of the UN, has largely achieved the goal of preventing harmful signal interference, formulating technical standards promoting equipment compatibility, and establishing uniform operational rules of the road.  Until now, month long ITU spectrum planning conferences have reached closure on both mundane and critical matters, albeit at a slow and methodical pace. 

The paper explains how several chronic and emerging factors present challenges to the successful record of multilateral consensus building on space and spectrum issues.  The likelihood of collisions of spacecraft with other objects, including space debris and harmful signal interference has increased, because then United States has opted to make domestic satellite rules and frequency allocations in advance of final ITU consideration.  Additionally, China and Russia have sought an expansion of the ITU’s mission to include elements of Internet governance that could promote balkanization of Internet access and legitimize efforts by individual nations to surveil and control access to broadband networks.

The paper assesses whether and how UN agencies can continue to establish timely and effective policies and procedures for reducing space debris and the potential for spacecraft collisions, and preventing harmful signal interference.  The paper concludes that China, Russia, and the U.S., should renew efforts to promote collegiality, consensus building, and longstanding, shared goals.
