Signatory nations of the Artemis Accords convened in Abu Dhabi on May 21 and 22, 2025, to work through some of the hardest practical questions facing lunar exploration: what happens when an astronaut needs rescue on the moon, and how do countries avoid stepping on each other’s operations in space. The workshop, hosted by the United Arab Emirates, forced delegates to confront gaps between the Accords’ broad principles and the operational rules needed before crews actually land on the lunar surface. With crewed missions drawing closer, the stakes of leaving these questions unresolved are growing fast.
What the Abu Dhabi Workshop Tackled
The two-day event focused on two of the thorniest topics embedded in the Accords: non-interference between space activities and the registration and reporting of operations beyond Earth orbit. According to the UAE space agency, the workshop aimed to advance sustainable space cooperation by translating high-level commitments into working procedures. That framing matters because the Accords, signed by a growing coalition of nations, have until now operated more as a statement of intent than as an enforceable rulebook.
Discussions zeroed in on how signatories should notify one another about planned lunar activities and what constitutes “harmful interference” when two missions operate near the same site. NASA confirmed that the workshop covered non-interference and registration, signaling that these are no longer abstract policy debates but active operational planning items. As the workshop concluded, participants reaffirmed their commitment to upholding the principles outlined in the Accords, including the public release of scientific data.
Safety Zones and the Interference Problem
The concept of “safety zones” sits at the center of the interference debate. Under the Accords, nations are expected to establish temporary zones around their operations to prevent dangerous overlap, whether from rover traffic, dust plumes during landing, or competing resource extraction. NASA characterizes these zones as a tool for deconfliction in space, designed to avoid harmful interference without claiming sovereignty over lunar territory.
That distinction is easier to state than to enforce. A legal analysis published by International Legal Materials contextualizes how safety zones relate to deconfliction and harmful interference, noting the tension between operational exclusion and the Outer Space Treaty’s prohibition on national appropriation. The practical question is straightforward: if the United States declares a safety zone around an Artemis landing site, what obligation does another signatory, or a non-signatory like China, have to respect it? The Accords offer principles but no binding enforcement mechanism, and the Abu Dhabi discussions appear to have grappled with exactly this gap.
The risk is that safety zones, defined primarily by whichever nation arrives first with the most capable hardware, could function as de facto territorial claims. Smaller signatory nations may find their own planned operations constrained by zones drawn around U.S.-led missions. Without agreed-upon size limits, duration caps, or a dispute resolution process, the framework could quietly favor the countries with the largest programs. Delegates in Abu Dhabi were therefore not just discussing technical boundaries on lunar regolith; they were negotiating the balance between access for all and protection for those who invest early.
One potential avenue, hinted at in legal commentary and implementation talks, is to treat safety zones more like air-traffic corridors than fenced-off plots. Under that model, operators would publish detailed plans, including expected landing windows, rover routes, and communications frequencies. Other missions could then plan complementary paths rather than being shut out entirely. However, without shared standards for how such plans are filed and updated, even this cooperative approach could break down in the face of tight launch windows or unexpected mission changes.
Emergency Rescue Beyond Low Earth Orbit
Moon emergencies present a different and arguably more urgent challenge. Section 4 of the Accords addresses emergency assistance, with signatories committing to take all reasonable steps to render aid to astronauts in distress, according to the U.S. State Department. This principle draws on the 1968 Agreement on the Rescue of Astronauts, recorded in the U.N. treaty collection, which obliges countries to assist and return astronauts and space objects.
But the Rescue Agreement was written for low Earth orbit, where a capsule can splash down and be recovered within hours. The moon is a different problem entirely. A crew stranded at the lunar south pole cannot be reached by a quick launch from Cape Canaveral. Rescue would require a lander already in transit or pre-positioned hardware, and no signatory currently has that capability standing by. The Abu Dhabi discussions on emergency assistance likely confronted this reality: the legal duty to help exists, but the physical ability to deliver that help on the lunar surface does not yet match the commitment.
This gap between obligation and capability raises hard questions about liability. If a signatory nation’s crew suffers an emergency and no other nation can respond in time, does the Accords framework assign responsibility? The current text offers principles, not protocols, and translating “all reasonable steps” into concrete response timelines and shared infrastructure is the work that remains. Some space lawyers argue that emergency cooperation will have to be built into mission architectures from the outset, with interoperable docking systems, compatible life-support consumables, and shared communications standards.
For now, most of that coordination remains aspirational. NASA and its partners are promoting public-facing material, including educational series on exploration, that emphasize collaboration and mutual support. Yet the engineering reality is that early Artemis missions will be tightly optimized for specific objectives, leaving little spare mass or energy for contingency rescue equipment. Abu Dhabi’s value, participants suggest, lies in forcing these uncomfortable trade-offs into the open before emergencies occur.
Who Shapes the Rules
The Accords are a U.S.-led initiative, and that origin shapes the politics of every implementation discussion. NASA issued a release confirming that international partners deepened their commitment to the framework, and the agency has consistently framed the Accords as a voluntary, non-binding set of norms rooted in the Outer Space Treaty. Yet the practical effect of implementation workshops is to set defaults: the countries at the table now will define how safety zones are sized, how interference complaints are handled, and how emergency obligations are distributed.
Canada, one of the early signatories, has described itself in official updates as pleased to be part of a growing group of countries committed to the safety and sustainability of outer space activities. That language reflects broad support but does not reveal how individual nations weigh specific trade-offs, such as how much transparency to offer about commercial operations or how to share responsibility for expensive rescue capabilities. For emerging space actors, the question is whether joining the Accords gives them real influence over these rules or simply binds them to standards largely set by more established agencies.
NASA’s communications emphasize that the Accords are open to any nation that shares their principles, and outreach through platforms like NASA Plus underscores the message that lunar exploration is a global effort. Still, Abu Dhabi highlighted the asymmetry at the heart of the project: only a handful of signatories will field crewed landers in the near term, but all will live with the precedents those missions establish. The process of turning voluntary norms into day-to-day procedures is therefore as much about diplomacy as it is about engineering.
From Principles to Practice
The Abu Dhabi workshop did not rewrite the Artemis Accords, nor was it intended to. Instead, it marked a shift from drafting principles to rehearsing how they will work under pressure. On non-interference, delegates wrestled with how to define safety zones robust enough to protect fragile operations without sliding into territorial claims. On emergency assistance, they confronted the uncomfortable truth that moral and legal duties currently outpace practical rescue options.
As more nations sign onto the Accords and as lunar timelines accelerate, similar workshops will likely become the forums where the real rules of the road are hammered out. Success will depend on whether signatories can move beyond affirming shared values to building shared systems (registries, notification channels, technical standards, and eventually, cooperative rescue capabilities). In that sense, Abu Dhabi was less a ceremonial gathering than an early test of whether a diverse coalition can manage the complexities of a crowded, high-stakes lunar frontier.
