Abstract

Adopted in October 2020, the Artemis Accords are a set of 13 provisions establishing a principled framework for the sustainable human exploration of the Moon and the other celestial bodies, including the exploitation of their natural resources. This article examines the extent to which the Artemis Accords comply with international law and international standards. It argues that, while rooted on the provisions of the Outer Space Treaty, the Artemis Accords introduce a significant innovation in international space law by replacing the anticipatory approach to the regulation of outer space activities with the staged principle of adaptive governance.

I. INTRODUCTION

On 13 October 2020, eight States—namely, Australia, Canada, Italy, Japan, Luxembourg, the United Arab Emirates, the United Kingdom and the United States—signed the Artemis Accords, which are a set of 13 provisions aimed at facilitating international collaboration on sustainable human exploration projects. Ukraine joined a month later while negotiations with Brazil and other potential partners are currently under way. The Artemis Accords are part of the wider Artemis Program led by the US National Aeronautics and Space Administration (NASA).Footnote 1 The main purpose of the Artemis Program is to bring the first woman and the next man to the Moon by 2024, thus paving the way for future human exploration of Mars and other celestial bodies in the solar system.

A distinctive trait of the Artemis Program is that it envisages the construction of a permanent outpost on the Moon, which includes a dedicated orbital station (the lunar ‘Gateway’) and a self-sustaining lunar base (the ‘Moon Base Camp’). The realisation of the project requires significant economic investment, the use of cutting-edge technology and the utilisation of the natural resources of the Moon to build and maintain the human settlement on the lunar surface.

In order to implement the Artemis Program, NASA is seeking the international collaboration of States and commercial partners. To that end, it has elaborated a set of guidelines that will form an integral part of any subsequent agreement with international partners. In practice, States wishing to enter into collaboration with NASA must commit in advance to abide by the principles set forth in the Artemis Accords.Footnote 2

The adoption of the Artemis Accords has generated mixed reactions. Among the spacefaring States, Russia has lamented the impossibility of signing the Artemis Accords due to their being perceived as protecting the interests of the United States in pursuing the exploitation of the Moon's natural resources.Footnote 3 China has mostly remained silent due to NASA's legal inability to cooperate with Chinese agencies while disapproving of the US unilateral approach to regulating space activities.Footnote 4 Similarly, Germany has not expressed any official position about the Artemis Accords. However, being involved in the construction of the Orion capsule (the selected spacecraft for lunar missions), Germany stands out as a vital partner in NASA's Artemis Program.Footnote 5 Other international actors, such as the European Space Agency, have finalised agreements with NASA to collaborate on the creation of the lunar Gateway space station by providing two modules thereof.Footnote 6

In addition, some scholars argue that the implementation of the Artemis Accords may undermine international law. For instance, Hobe warns that ‘[t]he Artemis Accords are an attempt by the Americans to walk softly to legitimise their deviation from the Outer Space Treaty’.Footnote 7 While describing the Artemis Accords as a political project, von der Dunk argues that the intention of the United States is to gather consensus around its interpretation of the Outer Space Treaty with regard to the exploitation of the Moon's resources.Footnote 8

Taken together, the considerations above beg the question: are the Artemis Accords revolutionary? Can they significantly affect the development of international space law? This article examines the normative implications of the adoption of the Artemis Accords from two different, but interrelated, perspectives. Section II analyses the content and scope of the Artemis Accords with a view to determining the extent to which they comply with existent international law and international standards by incorporating, clarifying or integrating relevant international space law instruments. Subsequently, Section III evaluates whether the Artemis Accords significantly affect or challenge established practices in the multilateral process of law-making for outer space. Section IV concludes by arguing that, while remaining solidly grounded on the provisions of the Outer Space Treaty, the Artemis Accords introduce a significant innovation in international space law by replacing the anticipatory approach to the regulation of outer space activities with the staged (‘building blocks’) principle of adaptive governance.

II. Normative character of the Artemis Accords

In terms of content, the Artemis Accords aim at implementing the provisions of the Outer Space Treaty.Footnote 9 They thus establish a set of guidelines intended to foster best practices for the human exploration of celestial bodies—namely, peaceful uses of outer space, transparency, interoperability, assistance to personnel in outer space, registration of space objects, release of scientific data, preservation of outer space heritage, utilisation of space resources, deconfliction of space activities and sustainable use of outer space.Footnote 10 In terms of legal significance, formally the Artemis Accords are not binding.Footnote 11

For the sake of exposition, the provisions of the Artemis Accords can be grouped into three categories. The first category simply transposes provisions of the Outer Space Treaty into the text of the Artemis Accords. The second category implements provisions of the Outer Space Treaty, adding detail and clarity to the rights and obligations contained therein. The third category introduces new concepts. The explicit commitment of the signatories to operate within the boundaries of the Outer Space Treaty's principles makes the content of the Artemis Accords relatively uncontentious. However, a closer scrutiny reveals that certain provisions of the Artemis Accords go a step further than mere implementation, effectively introducing concepts and principles not mentioned in the Outer Space Treaty, thus raising issues of compatibility.

In the following subsections, the article examines the three categories of provisions contained in the Artemis Accords with a view to determining the extent to which they depart from consolidated principles of international space law. Firstly, it evaluates the provisions of the Artemis Accords incorporating provisions of the Outer Space Treaty and other relevant international law instruments (subsection A). It then analyses the provisions of the Artemis Accords adding detail to provisions of the Outer Space Treaty and other international instruments with a view to establishing whether they constitute subsequent practice within the meaning of Article 31 of the Vienna Convention on the Law of Treaties (VCLT)Footnote 12 (subsection B). Finally, it evaluates the provisions of the Artemis Accords introducing new legal concepts (subsection C).

A. Incorporating International Law Provisions

The provisions of the Artemis Accords incorporating those of the Outer Space Treaty and other international instruments can be clustered, in turn, into three types. The first type includes verbatim transpositions of provisions of the Outer Space Treaty into the text of the Artemis Accords. For instance, Section 3 of the Artemis Accords states that any activity carried out by the signatories shall be ‘exclusively for peaceful purposes’, thus replicating the provision contained in Article IV, paragraph 2, of the Outer Space Treaty.Footnote 13 Section 3 of the Artemis Accords also requires that the signatories carry out their activities ‘in accordance with international law’, thus mirroring the provision contained in Article III of the Outer Space Treaty.Footnote 14 Likewise, Section 6 of the Artemis Accords requires the signatories to ‘render necessary assistance to personnel in outer space who are in distress’, thus replicating the obligation under Article V of the Outer Space Treaty.Footnote 15 This type of provisions is uncontroversial.

The second type consists of provisions that cite articles of the Outer Space Treaty instead of replicating their content. For example, Section 4 of the Artemis Accords requires the signatory States to share scientific information resulting from their space activities with the public and the scientific community on a good faith basis and ‘consistent with Article XI of the Outer Space Treaty’—that is to say, providing the details of the nature, conduct and locations of such activities.Footnote 16 This type of provisions, like the first one, does not add any right or obligation to States that are not already contemplated in the Outer Space Treaty. Hence, it is uncontroversial.

The third type includes provisions of the Artemis Accords loosely related to the text of the Outer Space Treaty, but nonetheless grounded on international law instruments. For example, Section 4 of the Artemis Accords requires the signatory States to adopt standards that will ensure the interoperability of any infrastructure used for space-based exploration. The provision reflects established practice in the field of international cooperation in outer space, dating back to the historic docking of the joint Apollo–Soyuz mission in 1975.Footnote 17 The rationale behind the requirement of standardisation of the space infrastructure lies predominantly in humanitarian considerations—namely, the ability to provide assistance to the personnel of other States in distress. In this respect, the provision of Section 5 of the Artemis Accords also relates to Article V, paragraph 2, of the Outer Space Treaty, which requires astronauts to ‘render all possible assistance to the other astronauts of the other States Parties’.

Another example is the provision on registration of space objects contained in Section 7 of the Artemis Accords. Registration of space objects allows the identification of States and international organisations operating in outer space. By requiring the signatory States to determine which of them should register any relevant space object, the Artemis Accords indirectly refer to the provisions of Article V (return of space objects and astronauts in the event of accident, distress or emergency landing) and Article VII (liability of the launching State for damage caused by the space object) of the Outer Space Treaty. Finally, Section 12 of the Artemis Accords requires the signatories to include a plan for space debris mitigation in bilateral agreements. Space debris is a phenomenon caused by the growing number of satellites orbiting the Earth. As such, it is not contemplated by the provisions of the Outer Space Treaty. Nevertheless, the provisions of Section 12 of the Artemis Accords may be related to, and interpreted in the light of, the duties of States to conduct space activities ‘with due regard to the corresponding interests’ of other States set forth in Article IX of the Outer Space Treaty. Overall, this type of provisions of the Artemis Accords does not depart from established international practice. As a result, it remains uncontroversial.

B. Refining International Law Provisions

Two sections of the Artemis Accords contain provisions aimed at operationalising corresponding obligations found in the Outer Space Treaty by clarifying the conduct required of States and other actors operating in outer space. This raises the question of whether the conclusion of the Artemis Accords amounts to subsequent practice within the meaning of Article 31(3)(b) of the VCLT—that is to say, for the purposes of treaty interpretation. Subsection I examines this issue by determining whether the provisions of Section 10 of the Artemis Accords (Space Resources) amount to subsequent practice in relation to the relevant provisions of the Outer Space Treaty. Subsection 2 performs the same task by focusing on the provisions of Section 11 of the Artemis Accords (Deconfliction of Space Activities).

1. Provisions on space resources

Subsequent practice may play a decisive role in clarifying the provisions of the Outer Space Treaty, which was adopted in 1967—a time when the space technology was still in its infancy—and contains provisions establishing basic principles of international space law. For instance, Article II thereof states that: ‘Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.’ Half a century after the adoption of the Outer Space Treaty, space technology has significantly advanced and space technology applications have become a common feature of everyday life. In light of this, Danilenko argues that new space activities require the adoption of more specific and detailed rules.Footnote 18 A passage from the work of the International Law Commission (ILC) Study Group on Treaties over Time is also noteworthy. It reads:

As important treaties reach a certain age … the context in which they operate becomes different from the one in which they were conceived. […] The parties to a treaty normally wish to preserve their agreement, albeit in a manner which conforms to present day exigencies. Subsequent agreement and subsequent practice aim at finding a flexible approach to treaty application and interpretation, one that is at the same time rational and predictable.Footnote 19

In this context, the interpretation of the principle of non-appropriation set forth in Article II of the Outer Space Treaty is the subject of Section 10 of the Artemis Accords, which concerns the extraction and utilisation of space resources. Paragraph 1 of the latter states that ‘the utilisation of space resources can benefit humankind by providing critical support for safe and sustainable operations’. The provision appears to refer to the utilisation of space resources in situ to support scientific operations whose findings will be shared with the public and the scientific community. In this respect, it is in line with the provisions of the Outer Space Treaty stating that the exploration and use of outer space shall be carried out for the benefit and in the interests of all countriesFootnote 20 and that States must facilitate international cooperation in the field of scientific investigation.Footnote 21

However, Section 10, paragraph 2, of the Artemis Accords provides a peculiar interpretation of the principle of non-appropriation of celestial bodies contained in Article II of the Outer Space Treaty by stating that ‘the extraction of space resources does not inherently constitute national appropriation’.Footnote 22 The same provision establishes that ‘contracts and other legal instruments relating to space resources should be consistent with the [Outer Space] Treaty’. Arguably, the reference in this second quotation is to Article VI of the Outer Space Treaty requiring States to authorise and provide continuing supervision to private actors performing activities in outer space. In my view, the element of novelty introduced here by the Artemis Accords is the clarification of the term ‘national appropriation’ contained in the Outer Space Treaty.

Indeed, the Outer Space Treaty is a compromise agreement which has been ratified by 110 States, including the spacefaring powers.Footnote 23 This raises the question of whether giving a specific meaning to the term national appropriation in Section 10, paragraph 2, of the Artemis Accords amounts to a new interpretation of Article II of the Outer Space Treaty in a context different from the one in which it was adopted.

The ILC considers subsequent practice as an authentic means of interpretation,Footnote 24 provided that it falls within the meaning of Article 31(3)(b) of the VCLT. The definition provided reads:

[Subsequent practice as an authentic means of treaty interpretation] consists of conduct in the application of a treaty, after its conclusion, which establishes the agreement of the parties regarding the interpretation of the treaty.Footnote 25

The definition contains two elements: conduct in the application of a treaty and the agreement between the parties stemming from that conduct. Accordingly, it is advisable to ascertain the presence of the two elements separately in order to establish whether the signing of the Artemis Accords by eight States amounts to subsequent practice able to modify the interpretation of the term ‘national appropriation’ contained in Article II of the Outer Space Treaty.Footnote 26

First, in relation to conduct, the identification of the relevant subsequent practice requires a determination as to whether the parties have taken a position regarding the interpretation of the treaty.Footnote 27 The ILC has clarified that ‘[s]uch position is not taken if the parties have merely agreed … to establish a practical arrangement (modus vivendi)’.Footnote 28 In my view, nothing in the conclusion of the Artemis Accords points to an agreement between the parties regarding the interpretation of the Outer Space Treaty. Nor does the text of the Artemis Accords refer to it, thus suggesting that the signatory States have agreed to establish a modus vivendi through the conclusion of subsequent bilateral agreements. It follows that the signatories to the Artemis Accords do not intend to amend or modify the Outer Space Treaty through conduct.Footnote 29 This is not to say that subsequent practice is irrelevant for the purposes of treaty interpretation. Quite the contrary, it may constitute a supplementary means of interpretation under Article 32 of the VCLT.

In this respect, the weight to be attributed to subsequent practice may be assessed against two criteria. The first criterion consists of clarity and specificity of the practice at hand.Footnote 30 Applied to Section 10, paragraph 2, of the Artemis Accords, it seems that the textual formulation of the provision presents an element of circular reasoning. Specifically, it states that the extraction and utilisation of space resources ‘should be executed in a manner that complies with the Outer Space Treaty’.Footnote 31 In my view, while containing a clear instruction, the provision lacks specificity. The further assertion that ‘the extraction of space resources does not inherently constitute national appropriation’Footnote 32 simply endorses one of the possible interpretations of the Outer Space Treaty (impliedly stating that the specific arrangements for extraction of natural resources—as detailed in the envisaged bilateral agreements—will be the determining factor of the lawfulness of that activity under the Outer Space Treaty).Footnote 33 As a result, the Artemis Accords do not satisfy the first criterion.

The second criterion concerns the repetition of the practice over time.Footnote 34 As things stand, the Artemis Accords have been signed by eight States comprising established and emerging spacefaring States alike. In the light of the number of States Parties to the Outer Space Treaty,Footnote 35 the figure is neither decisive nor insignificant for the purposes of treaty interpretation,Footnote 36 since the Artemis Accords will form the basis of further partnerships between NASA and any other State willing to contribute to the realisation of the Artemis Program. It thus appears that the weight of the Artemis Accords as subsequent practice must be considered in perspective and reassessed at a later stage. Eight signatures do not as such carry a heavy weight. This further suggests that the Artemis Accords do not satisfy the second criterion.

The second element of the definition of subsequent practice as an authentic means of treaty interpretation is the agreement of the parties regarding the interpretation of the treaty. The ILC clarified that an agreement under Article 31(3)(b) of the VCLT ‘requires a common understanding regarding the interpretation of a treaty which the parties are aware of and accept’.Footnote 37 The text of the Artemis Accords is unequivocal on this point, as it states that: ‘The Signatories affirm that the extraction of space resources does not inherently constitute national appropriation under Article II of the Outer Space Treaty.’Footnote 38 Therefore, it may be concluded that they contain a common understanding. Yet the contours of that understanding lack clarity and specificity, since the provisions of Section 10, paragraph 2, of the Artemis Accords do not contain any guidance as to the required, or simply suggested, modality of resource extraction other than the statement that ‘contracts and other legal instruments relating to space resources should be consistent with [the Outer Space Treaty]’.

Based on the considerations above, it is argued that, as a form of subsequent practice, Section 10 of the Artemis Accords does not represent an authentic interpretation of Article II of the Outer Space Treaty. Nor does it aim to change or modify existing interpretations thereof. Silence of one or more parties to the Outer Space Treaty may constitute acceptance of the subsequent practice induced by the implementation of the Artemis Accords,Footnote 39 potentially contributing to the formation of opinio juris relevant for the creation of a customary rule. However, given the negative reaction of spacefaring powers like Russia and China to the conclusion of the Artemis Accords,Footnote 40 for the time being this does not appear a realistic perspective.

2. Deconfliction of space activities

Section 11 of the Artemis Accords deals with the issue of deconfliction of space activities. Paragraphs 3 and 4 thereof refer to two principles set forth in Article IX of the Outer Space Treaty—namely, the principle that States should conduct their activities in outer space with due regard to the corresponding interests of the other States Parties to the treaty and the duty to avoid harmful interference with activities of other States Parties. In order to operationalise such principles, Section 11, paragraph 5, of the Artemis Accords requires the signatories to provide each other with the ‘necessary information regarding location and nature’ of their activities and create a ‘safety zone’ to avoid potential harmful interference.Footnote 41 Conceived as temporary,Footnote 42 safety zones serve two purposes. First, they aim at facilitating scientific discovery. Secondly, building on the provisions of Section 10 of the Artemis Accords, they represent a means for facilitating ‘the safe and efficient extraction and utilization of space resources in support of sustainable space exploration and other operations’.

Most notably, the concept of a safety zone is not mentioned in the Outer Space Treaty. In this respect, its introduction in Section 11 of the Artemis Accords represents a genuine innovation. At the same time, it is not an entirely new concept in the field of space law.Footnote 43 For instance, it has been discussed by the Hague International Space Resources Governance Working Group (hereinafter the Hague Working Group) as a means to ensure the long-term sustainability of outer space.Footnote 44 The latter is a concept also mentioned in Section 11, paragraph 2, of the Artemis Accords, which refers to the UN Guidelines for the Long-term Sustainability of Outer Space (2019).Footnote 45 This raises the question of whether the provisions of Section 11 of the Artemis Accords constitute subsequent practice under Article 31(3)(b) of the VCLT—that is to say, whether they are an authoritative interpretation of the Outer Space Treaty.

In terms of conduct,Footnote 46 Section 11, paragraph 7, of the Artemis Accords establishes four principles guiding the creation of safety zones that the signatories have committed to observe. They relate to size, scope and duration of safety zones, and are further complemented by provisions on information disclosure,Footnote 47 advance notification of the operationsFootnote 48 and periodic consultations with the other parties.Footnote 49 In this respect, the provisions of Section 11 appear to be both clear and specific. They also seem to be amenable to systematic repetition over time,Footnote 50 since the signatory States have explicitly and unequivocally committed to them without any specific time limit.

Equally, it is noteworthy that the creation of safety zones is only one of a range of possible ways to avoid harmful interference. As a result, the provisions of Section 11 of the Artemis Accords do not widen or restrict the scope of Article IX of the Outer Space Treaty. They nonetheless add detail and clarity to the text of the Outer Space Treaty, eventually introducing an element of innovation. From this limited perspective, they appear to fulfil the criteria of subsequent practice under Article 31(3)(b) of the VCLT.Footnote 51 A possible counterargument is that, being the Artemis Accords an initiative of the US, such subsequent practice does not reflect the agreement of all the States Parties to the Outer Space Treaty. This type of objection has a precedent in international practice. For instance, ICSID tribunals have recognised that ‘the view of one State does not make international law’.Footnote 52 Similarly, in Japan: Alcoholic Beverages II, the WTO Appellate Body held that: ‘An isolated act is generally not sufficient to establish subsequent practice; it is a sequence of acts establishing the agreement of the parties that is relevant.’Footnote 53

The argument above has merit, since the bilateral agreements incorporating the Artemis Accords are yet to be concluded.Footnote 54 Much remains to be seen about the extent to which the concept of safety zones will be embraced by the nascent space mining industry as well. Therefore, from this limited perspective, it can be concluded that the Artemis Accords may be regarded as emerging subsequent practice under Article 32 of the VCLT—that is to say, conduct by one or more parties in the application of the Outer Space Treaty carrying the value of supplementary, as opposed to authentic, means of interpretation.Footnote 55 Subsequent practice under Article 32 of the VCLT does not require the agreement of all the parties to a treaty.Footnote 56 Given the open resistance to the Artemis Accords by a number of States Parties to the Outer Space Treaty, this latter perspective appears to be preferred.Footnote 57

C. Introducing New Concepts

Section 9 of the Artemis Accords introduces a novel concept in international space law—namely, the preservation of outer space heritage. Assuming the existence of a collective interest in its preservation,Footnote 58 outer space heritage is described as any ‘historically significant human or robotic landing site, artifact, spacecraft, and other evidence of activity on celestial bodies’ which the signatories have agreed to preserve ‘in accordance with mutually developed standards and practices’.Footnote 59 There is no provision in the Outer Space Treaty under which the concept of space heritage neatly falls. The closest provision is Article 7, paragraph 3, of the Moon Agreement. It reads:

States Parties shall report to other States Parties and to the Secretary-General concerning areas of the Moon having special scientific interest in order that, without prejudice to the rights of the other States Parties, consideration may be given to the designation of such areas as international scientific preserves for which special protective arrangements are to be agreed upon in consultation with the competent bodies of the United Nations.Footnote 60

It may be argued that, if the creation by special agreement of international scientific preserves does not violate the principle of free exploration and use of celestial bodies, by analogy the same applies to the creation of international historical and cultural preserves. Section 9, paragraph 2, of the Artemis Accords appears to support the analogy by requiring the signatory States to engage in multilateral efforts to develop rules aimed at preserving outer space heritage. In practice, protecting sites and artifacts of historic value on the surface of the Moon (and, in perspective, other celestial bodies) entails the creation of a safety zone in order to prevent the plume effect.Footnote 61 The main difference between the creation of a safety zone for the purpose of facilitating the utilisation of the natural resources of celestial bodies and the creation of a safety zone for the purpose of protecting human heritage in outer space is that the latter would create a deconfliction zone aimed at preventing harm to landing sites and non-operational objects, such as artifacts, rather than human beings.Footnote 62

As objects launched into outer space, human artifacts and spacecraft remain property of the State that placed them on a celestial body.Footnote 63 An example is the flag planted by the Apollo 11 mission in 1969 or the Chinese flag planted by the Chang'e 5 mission in 2020. It is unclear whether the same considerations apply to the status of ‘other evidence of activity on a celestial body’,Footnote 64 such as Neil Armstrong's boot prints on the landing site of the 1969 Apollo 11 mission or the tracks of the Lunar Roving Vehicle used by the Apollo 15 mission in 1971. The Outer Space Treaty does not provide any criteria that may help qualify relevant objects with historical value as outer space heritage. Nor does the UNESCO World Heritage Convention,Footnote 65 since Article 4 thereof provides that States can identify and preserve only objects situated on their territory. Taken at face value, this provision clashes with the principle of non-appropriation set forth in Article II of the Outer Space Treaty. As a result, the Artemis Accords recognise that States should engage in multilateral efforts aimed at elaborating a definition of outer space heritage and related criteria for identification.Footnote 66

In this context, the signatories to the Artemis Accords can only assume that certain human and robotic artifacts possess significant historical value and treat them accordingly by establishing a safety zone around the objects potentially affected by the plume effect or other harmful activities. An argument is therefore made that causing damage to an object recognised of having historic value for humankind would trigger State responsibility for violation of the principle of due regard to corresponding interests of other States set forth in Article IX of the Outer Space Treaty.

However, as an obligation of conduct, it is not clear which elements constitute the benchmarks for assessing a violation of the principle of due regard. So far, only two international tribunals have referred to it in context of law of the sea disputes.Footnote 67 In particular, in the Chagos case, the arbitral tribunal held that the principle of due regard acquires meaning in relation to the circumstances of the case and the nature of the rights involved.Footnote 68 As a result, it declined to find ‘any universal rule of conduct’.Footnote 69 Equally, it is not clear what sort of reparation the damage to heritage in outer space would entail.Footnote 70 On the one hand, due to the nature of the objects at hand, it seems unlikely that States would be able to return the object to its initial condition or replace it. On the other hand, determining the amount of compensation as well as the beneficiaries of such compensation is likely to pose new challenges to States conducting activities in outer space under the Artemis Accords.

In light of the above, it appears that the concept of heritage in outer space is not incompatible with the provisions of the Outer Space Treaty, although the latter are inadequate to provide effective protection and need to be supplemented by bespoke rules widely accepted by the international community. In this respect, Section 9 of the Artemis Accords appears to be a significant innovation compared to the provisions of the Outer Space Treaty.

III. Impact of the Artemis Accords on the development of international space law

From a substantive point of view, the Artemis Accords appear to be grounded on established principles of international space law and, in particular, the provisions of the Outer Space Treaty. In this respect, they are innovative but not revolutionary. However, from a formal perspective, they noticeably depart from the practice of negotiating the governing principles of international space law within the United Nations. Therefore, this section evaluates the impact of the Artemis Accords on the development of international space law by determining whether their process of adoption amounts to a potentially new model for outer space law-making.

The starting point of the analysis is that the UN treaties on outer space have been adopted in the 1960s and 1970s at the height of the Cold War confrontation between the US and the Soviet Union and reflect the mutually acceptable compromise between the two ideological blocs.Footnote 71 In the absence of any previous regulation in this field and mindful of the fact that the technology used to perform space activities can accommodate both peaceful and non-peaceful purposes,Footnote 72 the UN space treaties attempt to regulate any future activity of States in outer space by establishing broad principles. In this respect, they represent the hallmark of the anticipatory character of space regulation.

Technically, anticipatory regulation consists of producing rules aimed at governing situations that may arise only in the future.Footnote 73 As Danilenko writes:

While anticipatory regulation may be useful for the establishment of a broad legal framework for future state activities, it is dangerous to rely on it too heavily in cases where detailed regulation of complex technical or economic issues is required.Footnote 74

Indeed, with the advent of globalisation, the scope of outer space activities has acquired a whole new dimension. As a result of scientific and technological advances, the provisions of the UN outer space treaties appear increasingly in need of refinement in order to be able to govern new activities in outer space, both scientific and commercial.Footnote 75 In particular, the emergence of private actors as full-fledged participants in the exploration and use of outer space has determined a shift of emphasis from multilateral fora such as COPUOS to the domestic forum as the preferred setting for States to develop their space policies.Footnote 76 This trend is most noticeable in the regulation of space resource activities. For instance, the US and Luxembourg have dedicated legislation conferring property rights to companies mining outer space resources.Footnote 77 Such States claim to be acting within the boundaries of the multilateral treaties on outer space that they have ratified.Footnote 78

In this context, the Artemis Accords turn out to be the cusp of a wider trend in the law-making process for outer space, sitting at the crossroads of multilateralism and unilateral national legislation. Aimed at establishing a core of principles to be included in future bilateral agreements between NASA and each signatory State, they spell out the basis for subsequent agreements without providing the details of such agreements. At the same time, their broad provisions are forward-looking, for they require the signatories to perform actions the regulation of which are the subject of future multilateral negotiation. In doing so, they depart from the anticipatory approach to regulation of outer space activities endorsed by the UN outer space treaties.

This suggests that the Artemis Accords are an instrument of space governance rather than a mere set of rules. On the one hand, they do not aim at introducing any new principle of international space law. As discussed in Section II above, the Artemis Accords are rooted on the provisions of the Outer Space Treaty. On the other hand, they provide the blueprint for a model of governance of space resource activities. From this limited perspective, they partake in a broader trend consolidating the concept of staged governance for the exploitation of space resources.

The staged approach to space governance has been developed by the Hague Working Group.Footnote 79 Led by a consortium of academic institutions, the project stands out for its openness in terms of stakeholders’ representation—government representatives, civil society groups and space industries—and has concluded its work by issuing a set of guidelines. To a large extent, the provisions of the Artemis Accords align with the recommendations of the Hague Working Group, which are also known as the ‘Building Blocks’.Footnote 80

The Building Blocks endorse the principle of adaptive governance.Footnote 81 The latter is a form of environmental governance aimed at coordinating resource management regimes in situations of complexity and uncertainty determined by rapid environmental change.Footnote 82 A concept of recent origin,Footnote 83 adaptive governance recognises the existence of a link between social and ecological systems. Accordingly, it envisages the creation of frameworks of governance that are receptive of the feedbacks originating both in the social and ecological systems—hence, they continually evolve through adaptation.Footnote 84 The implementation of an adaptive governance framework requires a range of interactions between institutions, networks and actors. Applied to the field of space resource exploitation, reliance on the principle of adaptive governance entails a step-by-step, incremental approach to the regulation of space resource activitiesFootnote 85 involving all the relevant stakeholders.Footnote 86

A comparison between the provisions of the Artemis Accords and those of the Building Blocks shows the existence of a high degree of compatibility between the two instruments (Table 1). Moreover, the provisions of the Artemis Accords operationalising provisions of the Outer Space TreatyFootnote 87 or introducing new conceptsFootnote 88 require the signatory States to engage in multilateral efforts to add further detail to those provisions. Specifically, they require States to use their experience to inform multilateral discussions and be receptive of the outcome thereof, thus creating the feedback effect characterising the concept of adaptive governance.

Table 1: Comparison between the Artemis Accords and the Building Blocks

Comparison between the content of the Sections of the Artemis Accords (S) and the corresponding provisions of the Building Blocks (BB).

For instance, Section 10, paragraph 4, of the Artemis Accords provides that:

The Signatories intend to use their experience under the Accords to contribute to multilateral efforts to further develop international practices and rules applicable to the extraction and utilization of space resources, including through ongoing efforts at the COPUOS.

The provision above recalls Building Block 8.1, which states that rights over resources extracted from celestial bodies ‘can lawfully be acquired through domestic legislation, bilateral agreements and/or multilateral agreement’.Footnote 89 Such rights must be mutually recognised by the parties and subsequently registered in order to ensure transparency.Footnote 90 From this perspective, the process of definition of resource rights turns out to be a pragmatic one based on the actual practice of space operators, which both influences and is influenced by the outcome of discussions in different multilateral fora. The difference with the anticipatory approach to the regulation of space resource activities set forth in the Moon Agreement—which subordinates the exploitation of the natural resources of the moon to the conclusion of an international framework contemplating appropriate procedures for the material execution of mining activities—is striking.Footnote 91

In a similar vein, Section 11, paragraph 6, of the Artemis Accords states that:

The Signatories intend to use their experience under the Accords to contribute to multilateral efforts to further develop international practices, criteria, and rules applicable to the definition and determination of safety zones and harmful interference.

As discussed in Section II.B.2 above, the Outer Space Treaty does not refer to the concept of safety zone. It only refers to the principle underlying the creation of safety zones—that is to say, avoiding harmful interference with the activities of the other parties.Footnote 92 Likewise, Building Block 11.3 encourages the establishment of safety zones ‘to assure safety and avoid any harmful interference’ with space resource activities. This further demonstrates that international practice is increasingly taken as the starting point, rather than the outcome, of multilateral discussions—in this case, discussions aimed at gathering consensus on the concept and regulation of safety zones. In doing so, the practice of actors operating in outer space remains open to the feedback originating in multilateral fora, thus adapting to new regulatory frameworks.Footnote 93

Last but not least, Section 9 of the Artemis Accords invites the commencement of multilateral discussions to develop the concept of outer space heritage.Footnote 94 It is also noteworthy that Building Blocks 10 and 18 refer several times to ‘designated and internationally endorsed outer space natural or cultural heritage sites’ with a view to protecting them against potentially harmful activities.Footnote 95 This provides further evidence that, within an adaptive governance framework, practice is both the springboard for and the outcome of multilateral negotiation.

In light of the above, it is suggested that the endorsement of the principle of adaptive governance in the Artemis Accords has emerged as a new method of reaching international consensus on outer space activities. The main advantage of this new form of decision-making process is that it remains a speedy and flexible mechanism operating within the boundaries of the Outer Space Treaty. Another advantage is that it promotes collaboration, thus avoiding unilateralism. However, a possible downside is that, by giving prominence to the interests of spacefaring States,Footnote 96 it may widen the gap between developed and developing countries in terms of benefit sharing stemming from the exploitation of outer space resources. In this sense, it may weaken genuine international cooperation eventually running counter the spirit of Article III of the Outer Space Treaty.

Most notably, the Artemis Accords do not refer to sharing of benefits stemming from outer space activities. Equally, they do not envision any institutional arrangement for the implementation and review of space governance frameworks. Nor do they contemplate a dispute settlement mechanism. At the moment, this is a significant flaw. Yet the signatories’ commitment to multilateral efforts and periodic reviewFootnote 97 of the text of the Artemis Accords does not preclude any change in that direction, thus accommodating the possibility of further evolution. In this respect, the Artemis Accords may benefit from developing along the lines of the Building Blocks, which are likely to form the basis of both national and international frameworks for the governance of space resource activities.Footnote 98 I provide three examples.

First, Building Block 13 develops the concept of benefit sharing, which consists of actions aimed at promoting and facilitating space training and technology as well as joint ventures and exchange of expertise on a mutually acceptable basis. Most importantly, it calls for the creation of a voluntary international fund while excluding any forms of compulsory monetary sharing of benefits. In doing so, it moves away from the rigid interpretation of equitable sharing as equal sharing characterising the developing countries’ original interpretation of celestial bodies as the common heritage of mankind.Footnote 99 Since the provisions of Building Block 13 are compatible with the Outer Space Treaty and the Moon Agreement stipulating that ‘the exploration and use of outer space, including the Moon and other celestial bodies, shall be carried out for the benefit and in the interests of all countries’,Footnote 100 they would accommodate the obligations of the signatories to the Artemis Accords, including those who have also signed or ratified the Moon Agreement.

Secondly, Building Block 18 outlines the basic functions that an international framework for the governance of space resource activities should serve. They include the creation and management of a registry for priority rights, a separate database providing information about various aspects of space resource activities—including advance notification and termination of such activities—as well as the establishment of an international body with the mandate of listing the internationally recognised heritage sites and monitoring, including reviewing, the implementation of the international framework. In my view, this would directly contribute to the realisation of the principle of free access to outer space set forth in Article I of the Outer Space Treaty. It would also comply with the provisions of Article 5, paragraph 1, of the Moon Agreement requiring States to inform the UN Secretary-General and the international community of their activities on the Moon, thus satisfying the international obligations of the signatories to the Artemis Accords who have also signed or ratified the Moon Agreement.

Finally, Building Block 19 provides a list of available dispute settlement mechanisms—adjudicatory, non-adjudicatory and hybrid ones. They are the mechanisms currently in use to facilitate the peaceful solution of disputes arising from outer space activities. The provision is uncontroversial and does not promote one particular method over the others. It simply reinforces the broader principle of peaceful uses of outer space. A provision along these lines would be a welcome addition to the text of the Artemis Accords as well.

IV. Conclusion

The Artemis Accords are an international framework for cooperation in the sustainable human exploration of outer space designed to be compliant with the obligations of the Outer Space Treaty. Although not binding, they provide a principled approach for conducting space resource activities. A characteristic of the Artemis Accords is that they encourage and facilitate the implementation of the Outer Space Treaty's obligations even in the absence of an international instrument regulating the exploitation of outer space resources. Specifically, by replacing the concept of anticipatory regulation with the principle of adaptive governance as the basis of international cooperation in this field, the Artemis Accords present themselves as a starting point for further discussion of an international framework on space resource activities. Indeed, several provisions of the Artemis Accords call for further elaboration in a multilateral context. Given the current stage of development of space technology, the feasibility of the commercial exploitation of the natural resources of the Moon and other celestial bodies appears imminent. As a result, breaking the impasse created by the adoption of the Moon Agreement in 1979 appears both necessary and advisable. The Artemis Accords provide a concrete step in that direction.

Overall, it appears that the Artemis Accords are highly innovative. By operating within the remit of the multilateral treaties on outer space, they advance the development of international space law without revolutionising it.
