In just 18 days, six countries on four continents joined the U.S.-led Artemis Accords, pushing the lunar coalition from 61 to 67 member nations in what appears to be the fastest expansion wave since the agreement launched in 2020. Paraguay became the latest signatory on May 7, 2026, when Osvaldo Almiron Riveros, Minister President of the Paraguayan Space Agency, put pen to paper in Asuncion. The rapid-fire additions come as NASA prepares for crewed landings near the Moon’s south pole and as Washington works to rally international support for its vision of how countries and companies should behave beyond Earth.
Six signatories in 18 days
The streak began on April 20 when Latvia signed on as the 62nd member. Three days later, Jordan formalized its commitment at NASA Headquarters in Washington, becoming the 63rd signatory, a milestone confirmed independently by the Jordan News Agency. Morocco followed on April 29 in Rabat, where Foreign Minister Nasser Bourita signed alongside senior U.S. officials, making the North African kingdom the 64th nation in the Accords.
Then came May 4, when both Ireland and Malta added their names. Ireland was recorded as the 66th signatory, and NASA’s announcement welcoming Malta described the island nation as the newest member at the time, underscoring just how tightly packed the sequence had become. The numbering implies a 65th country signed between Morocco and Ireland, but no NASA release in the available reporting identifies that nation or its signing date; without primary confirmation, the identity and timing of the 65th signatory cannot be stated with certainty. Paraguay closed the run three days later as the 67th signatory.
What the Artemis Accords actually require
The Accords are a set of non-binding principles rooted in the 1967 Outer Space Treaty. Signatories commit to transparency in space activities, interoperability of equipment and data, mutual assistance during emergencies, preservation of historic sites such as the Apollo landing zones, and the peaceful use of space resources. NASA maintains the official text and a running list of signatories.
Crucially, the Accords are not a treaty ratified by national legislatures. They function more like a diplomatic handshake: participating governments align themselves with American-led norms for lunar and deep-space operations without taking on legally enforceable obligations. That distinction matters because it makes signing politically easy but leaves enforcement and follow-through largely undefined.
Why the geographic spread matters
Latvia and Ireland bring additional European Union members into the fold, reinforcing an already strong European presence. Jordan and Morocco extend the framework across the Arab world and North Africa, regions where multilateral space cooperation has historically been limited. Malta, one of Europe’s smallest states, adds another Mediterranean voice. And Paraguay deepens Latin American participation, following earlier signatories such as Colombia, Ecuador, and Argentina.
The diversity is deliberate. The Accords are designed to build a critical mass of countries that accept shared rules before commercial and government-led missions begin extracting water ice, minerals, or other resources on the lunar surface. Every new flag on the list strengthens Washington’s argument that its framework represents an emerging international consensus rather than a unilateral American project.
The rival framework: China and Russia’s lunar station
The Artemis Accords are not the only game in town. China and Russia have been recruiting partners for their International Lunar Research Station (ILRS), a competing initiative that envisions a permanent base on the Moon’s surface. Countries including Pakistan, Venezuela, South Africa, Egypt, and Belarus have publicly expressed support for or signed onto the ILRS, though the partnership structure and commitments vary widely and no single authoritative tally exists.
Neither program explicitly mentions the other in official documents, but the parallel recruitment drives have created a quiet competition for allegiance, particularly among nations in Africa, the Middle East, and Southeast Asia that have not yet committed to either side. The Accords’ sprint to 67 members suggests Washington sees urgency in locking in partners before the lines harden further.
What signing does not guarantee
None of the NASA announcements for the six newest members specify funding commitments, technology-sharing deals, or mission roles. Paraguay’s domestic space agency budget and technical capacity, for instance, are not described in any available official document. Malta’s concrete contributions beyond a pledge to abide by the principles remain undefined.
The gap between signing and participating in actual lunar operations could be wide. Whether smaller signatories gain access to Artemis mission hardware, scientific data, or launch opportunities is not spelled out in the public record. The Accords establish norms, not contracts.
There is also the unresolved question of resource extraction. The Accords endorse the idea that using space resources can be consistent with the Outer Space Treaty, but they stop short of defining legal mechanisms for ownership, profit-sharing, or dispute resolution over extraction zones. Those questions will likely surface only when missions begin harvesting water ice near the lunar south pole, a scenario NASA is actively planning for with its Artemis III and subsequent crewed landing missions.
From diplomatic handshake to operational involvement
The key metric going forward is whether any of these six new signatories move from signature to operational involvement. That could take the form of scientific instruments on future Artemis landers, ground-station agreements supporting communications and navigation, astronaut training partnerships, or contributions to the planned Lunar Gateway station. It could also mean regulatory changes at home, such as national licensing frameworks for private space companies that explicitly reference Accords principles.
Until those concrete steps appear in official program documents or national policies, the expansion to 67 members is best understood as a diplomatic foundation. It shows that a wide and growing array of countries are willing to endorse common rules for space activity. But it does not yet show how those rules will hold up when hardware lands, resources flow, and real money is at stake. The next phase, where principles meet practice on and around the Moon, will determine whether this fast-growing coalition becomes a durable framework for exploration or remains largely a statement of good intentions.
