¹ A space system includes “all devices and organizations forming the space network,” which includes the satellite(s), the transmissions, and the ground station and associated infrastructure. “Space assets” are elements of space systems and are the “equipment that is an individual part of a space system, which is or can be placed in space or directly supports space activity terrestrially.” United States Department of Defence, DOD Dictionary of Military and Associated Terms (July 2017) at 215-16, online: <http://www.dtic.mil/doctrine/new_pubs/dictionary.pdf>.

⁴² It should be noted that jamming could be endorsed as an appropriate measure under Article 41 of the United Nations Charter; otherwise, it is generally considered to be interference. Jamming may be permitted where the United Nations (UN) Security Council calls upon member states to interrupt “postal, telegraphic, radio or other means of communication” in response to a threat to peace, a breach of the peace or aggression.

⁴³ Housen-Couriel, supra note 13 at 434, 437, 440. Space systems are vulnerable to two main threats: non-kinetic (which can include electromagnetic interference or cyber-enabled interference) or kinetic (the effect of physically interfering, damaging, or destroying another satellite with another object either in orbit or launched from the ground for that purpose — e.g., direct assent anti-satellite weapons). This “dual threat” is amplified by cyber interference as satellites, the transmissions, and their associated ground stations are connected, commanded, and controlled using cyber platforms. However, cyber interference is outside the scope of this article. Lewis & Livingstone, supra note 34.

⁴⁹ More recently, interference by cyber means has risen, with hackers gaining full functional control of the National Aeronautics and Space Administration (NASA) computers in 2011. This particular hacking incident resulted in the hackers getting full system access, which would have allowed them to “modify, copy or delete sensitive files,” which could have affected the International Space Station. In addition, between 2010 and 2011, NASA suffered 5,408 computer security incidents. Hacks to NASA systems range from those perpetrated by individuals testing their hacking skills, to organized criminal organizations looking for profit, to intrusions that may be sponsored by foreign intelligence services. “Hackers Had ‘Full Functional Control’ of NASA Computers,” British Broadcasting Corporation (8 March 2012), online: <http://www.bbc.com/news/technology-17231695>.

⁶⁶ It should be noted that under art 2(4) of the UN Charter, interference with satellite signals would not generally amount to a threat of force or a use of force against the territorial integrity or political independence of a state. However, depending on the effects of space-based or ground-based interference and the type of system affected, it may be considered to rise to the level of a threat of force, use of force or armed attack, and, therefore, the law relating to the use of force (jus ad bellum) or international humanitarian law (jus in bello) could apply depending on the situation.

⁶⁷ A mega-constellation is a collection of related satellites, usually in low Earth orbit (LEO) operating to provide increased coverage and resilience for a particular satellite service. An example of a mega-constellation is OneWeb, which is planning a constellation of 648 satellites in LEO to provide global broadband communications services. Other proposed mega-constellations are considering using 1,400 and 3,000 satellites.

⁶⁸ Orbital space debris can occur when a piece of space debris is in orbit itself and strikes another space asset or piece of debris, which is called a conjunction. Space debris can have catastrophic effects if it hits a functioning satellite, not only in the first instance by disabling, degrading, or destroying the satellite but also in then producing pieces of debris that, due to the Kessler effect, result in the propagation of more and more space debris as secondary and tertiary effects. Wright, Grego & Gronlund, supra note 26 at 136.

In utilizing space for social, economic, and national security activities, it is generally accepted that the risk of damage or injury should not be passed from “the creator of the risk to the public at large,” except in certain circumstances where the launching state reaps the benefits; however, damages in that context would be dealt with under domestic law via a claim against a government.

Some examples include the Convention on Damage Caused by Foreign Aircraft to Third Parties on the Surface, which indicates that “any person who suffers damage on the surface shall, upon proof only that damage was caused by an aircraft in flight or by any person or thing falling therefrom, be entitled to compensation.” Convention on Damage Caused by Foreign Aircraft to Third Parties on the Surface, 7 October 1952, 310 UNTS 182 (entered into force 4 February 1958). A similar principle has been applied to atomic energy, which utilizes similar absolute liability regimes, including the Convention on Third Party Liability in the Field of Nuclear Energy, 29 July 1960, 956 UNTS 251 (entered into force 1 April 1968), and the Convention on the Liability of Operators of Nuclear Ships, 25 May 1962, 57 AJIL 268 [Nuclear Ships Convention]. Art II of the Nuclear Ships Convention provides that “[t]he operator of a nuclear ship shall be absolutely liable for any nuclear damage upon proof that such damage has been caused by a nuclear incident involving the nuclear fuel of, or radioactive products or waste produced in, such ship.” International Convention on Civil Liability for Nuclear Damage, 21 May 1963, 1063 UNTS 265 (entered into force 12 November 1977).

¹⁰² Dembling, supra note 95 at 34. Absolute liability is contrasted with “fault-based liability,” which is “liability based on some degree of blameworthiness.” Black’s Law Dictionary, 9th ed, sub verbo “fault-based liability.” “Fault” is defined as “an error or defect of judgement or of conduct; any deviation from prudence or duty resulting from inattention, incapacity, perversity, bad faith, or mismanagement. Under the civil law, “fault” is “the intentional or negligent failure to maintain some standard of conduct when that failure results in harm to another person.” Black’s Law Dictionary, 9^th ed, sub verbo “fault.”

¹⁰⁶ Outer Space Treaty, supra note 7, art VI. It should be noted that there are interpretation differences between the various translations of the text of the Liability Convention, in that the French and Spanish versions do not recognize a difference between “responsibility” and “liability.” Different translated versions also provide varying scopes of application for absolute liability.

²⁰⁰ The issue of lex specialis and how it applies to specialized bodies of law that interact has been much debated, particularly as it relates to the interaction of international humanitarian law (IHL) and international human rights law (IHRL). Legality of the Threat or Use of Nuclear Weapons, Advisory Opinion, [1996] ICJ Rep 226 at para 25; Legal Consequences of the Construction of a Wall in the Occupied Palestinian Territory, Advisory Opinion, [2004] ICJ Rep 136 at para 106; Armed Activities on the Territory of the Congo (Democratic Republic of the Congo v Uganda), [2005] ICJ Rep 168 at paras 216–20. These discussions reflect the view that potentially competing lex specialis should be read harmoniously to the greatest extent possible and that the analysis should be considered through the lens of the specialized body of law. Further consideration of the interaction of other areas of international law (i.e., IHL and IHRL) and how they may apply in the present scenarios is outside the scope of this article.

²⁰⁹ The interference event may provide a signature that can be used to determine the source. However, due to the nature of the space domain, especially where there is no damage to a space asset, it may not be suspicious due to the expansive and “distant nature of the domain” and the ability to masquerade assets as those operating for other purposes (i.e., military satellites pretending to be civilian or commercial). Zenko, supra note 48.

²¹⁰ This was the case when Sputnik I was launched, as the United States did not launch a protest because they wanted to take advantage of the orbital overflight of other countries when they launched their own satellite shortly thereafter. Mountin, supra note 5 at 139.
