Serbia signs into NASA’s civil space governance framework at 5 p.m. ET today at NASA Headquarters in Washington — making the Balkan nation the 69th country to join the Artemis Accords. The ceremony would be unremarkable coalition paperwork if not for one detail the official announcement omits: just six weeks ago, Serbian President Aleksandar Vučić called his state visit to Beijing the most important of his career, walked away with China’s Friendship Medal, and confirmed that the first satellite his country will ever launch is being built with technology from a subsidiary of China’s national space authority.
Serbia is not choosing between Washington and Beijing in space. It is choosing both — and today’s signing makes that balancing act official on the American side.
What Serbia Is Actually Joining
The Artemis Accords are not a treaty. That distinction matters more than the ceremony suggests. Drafted by NASA and the U.S. Department of State and first signed on October 13, 2020, the Accords are a set of non-binding political commitments — they exist outside the UN Charter’s Article 102 treaty framework, which means they carry no enforcement mechanism, no dispute resolution process, and no liability structure if a signatory acts inconsistently with the document’s principles, as Britannica’s analysis of the Accords confirms. A country that signs and then ignores the principles faces no legal consequence beyond diplomatic friction.
What the Accords do establish is a governance framework grounded in the 1967 Outer Space Treaty, covering nine practical areas: peaceful exploration, transparency about national space activities, interoperability of systems, emergency assistance to personnel in distress, open sharing of scientific data, space resource extraction consistent with the Outer Space Treaty, orbital debris mitigation, preservation of historic sites such as Apollo landing zones, and “safety zones” — the most technically specific provision.
Safety zones require a signatory to notify others of its space activities and coordinate to avoid “harmful interference” within a defined operational area. The size of a safety zone is determined through “commonly accepted scientific and engineering principles,” language that is deliberately vague and leaves implementation to bilateral negotiation. For a country like Serbia, which has no hardware in orbit yet, the safety zone provision is irrelevant today but would govern any future lunar operations it conducts or licenses.
The resource extraction provision is the most legally contested. The Accords affirm that extracting resources from the Moon, Mars, or asteroids does not inherently constitute national appropriation of the celestial body — which is prohibited under the Outer Space Treaty’s Article II. This is a specific U.S. interpretation of the Treaty’s language, and it is contested, as Boley and Byers argued in Science in 2020. Frans von der Dunk of the University of Nebraska-Lincoln has argued the Accords strengthen the U.S. interpretation of the Outer Space Treaty, effectively allowing private-sector commercial exploitation under U.S. legal authorization — a reading that critics say has never been validated by an international body.
From Eight Nations to Sixty-Nine
When NASA Deputy Administrator Matt Anderson hosts Serbia’s Foreign Minister Marko Đurić and State Department Assistant Secretary Wesley Brooks at the signing this afternoon, the coalition at the table will have grown from eight founding nations to sixty-nine in six years.
That expansion accelerated sharply in 2025 and 2026. Finland, Bangladesh, Norway, Senegal, Hungary, Malaysia, and the Philippines joined in 2025. Portugal, Oman, Latvia, Jordan, Morocco, Malta, Ireland, Paraguay, and Botswana joined in 2026 before today’s ceremony, as tracked in the Wikipedia Artemis Accords signatories list. Botswana became the 68th signatory on June 25 — just three weeks ago.
What Russia and China are not on that list matters as much as who is. Russia called the framework “akin to a blatant attempt to create international space law that favors the United States,” as documented in the Wikipedia Artemis Accords article. Chinese state-affiliated media compared it to colonial land-enclosure methods. The two nations are instead developing the International Lunar Research Station (ILRS) framework, offering an alternative for countries unwilling to operate under U.S.-drafted principles. Two countries — Thailand and Senegal — have now signed both the Artemis Accords and the ILRS framework, making them the live test cases for whether the two systems can coexist.
The critics’ structural objection — that 69 bilateral agreements between each country and the United States effectively allow Washington to set the rules for a global commons — has not slowed signatory growth. But it has never been formally rebutted, either.
Serbia Joins Artemis Accords — With Chinese Engineers Building Its First Satellite
Serbia has no dedicated national space agency. Its space activities have largely been confined to non-governmental organizations, with SERBSPACE — the Serbian Office for Space Sciences, Research and Development, an NGO founded in Belgrade in 2016 — serving as the country’s primary voice in international space bodies.
What Serbia does have is a satellite under construction. Named “Mozaik” (Mosaic), the country’s first spacecraft is being developed at the Belgrade Astronomical Observatory in partnership with the Faculty of Mechanical Engineering, the Faculty of Mathematics, and the Mihajlo Pupin Institute. The satellite’s primary scientific goal is to observe the Sun in the X-ray domain — an observation impossible from Earth, where the atmosphere blocks X-ray radiation — using a spectrometer developed by Serbian scientists, as CGTN reported.
The platform itself is being provided by DFH Satellite Co. (DFHSat), a subsidiary of the Chinese Academy of Space Technology (CAST) — a Chinese state entity. That partnership has enabled the satellite to grow from an initial three-unit CubeSat design to an eight-unit configuration, a structural upgrade Luka Popovic, the Astronomical Observatory’s director, described as “a big step” toward eventually establishing a formal space agency.
The launch is now projected for late 2027, with Chinese partners providing technical expertise, the satellite platform, and launch support.
Because CAST is a state-controlled entity subject to China’s National Intelligence Law (2017) — which requires all organizations and citizens to “support, assist, and cooperate with national intelligence work” — the hardware architecture underlying Serbia’s first satellite originates from an entity with legal obligations to the Chinese government. No independent security audit of the Mozaik collaboration’s data-sharing protocols has been publicly released. The satellite also carries a secondary camera designed to provide daily optical imagery of Serbian territory.
How Serbia Ended Up Signing Both Frameworks
Serbia describes its foreign policy through a “four pillars” doctrine: balanced cooperation with the EU, the United States, Russia, and China simultaneously, with military neutrality as a constitutionally enshrined principle, as documented in the Journal of Liberty and International Affairs. The country’s arsenal physically embodies this approach — Russian MiGs, Chinese FK-3 air defense missiles, French Rafale fighters, and Airbus helicopters all serve in the Serbian military simultaneously.
The space domain now mirrors that balance. Serbia signed a memorandum of cooperation with Roscosmos in 2019. Its Mozaik satellite is being built with Chinese state-backed expertise. And today it is formally joining the U.S.-led civil space governance coalition.
The Chinese dimension of Serbia’s space program is deepening rather than narrowing. On May 24, 2026, Vučić traveled to Beijing in what he called the most important foreign visit of his career. President Xi Jinping awarded him the Friendship Medal of the People’s Republic of China — the country’s highest honor for foreign nationals. China became Serbia’s largest investor overall in 2025. A Serbian ministerial delegation attended the Russian Space Forum in April 2026 and confirmed the two countries would continue space cooperation.
In June 2026, just weeks before today’s Artemis ceremony, Dassault Aviation, Dassault Systèmes, and Thales signed industrial cooperation contracts with Serbia’s defense organizations at the Eurosatory 2026 exhibition in Paris, including a technology transfer agreement for UTVA Avio to manufacture components for the Rafale fighter and potentially enter Dassault’s global supplier network. The €2.7 billion Rafale acquisition that drove these agreements was itself signed in 2024.
Serbia is not forcing a strategic choice. It is deliberately refusing to make one.
What the Signing Actually Commits Serbia To
Signing the Artemis Accords does not obligate Serbia to contribute hardware, crew, funding, or expertise to any Artemis mission. It does not trigger any procurement relationship with NASA or any U.S. defense entity. What it establishes is a political commitment to the nine principles described above, and a positioning inside the governance coalition that would govern commercial and governmental lunar activity if the Artemis framework becomes the de facto global standard.
For Serbia, today’s ceremony is less about the Moon and more about signaling institutional alignment. With Mozaik projected to launch in late 2027 — inside the same timeframe as Artemis III, which NASA has redesigned as a low-Earth-orbit docking test for SpaceX’s Starship and Blue Origin’s Blue Moon lander — Serbia would enter orbit as both a new Artemis signatory and as a country whose first satellite was built by a Chinese state entity.
The first crewed Moon landing under the Artemis program has been pushed to Artemis IV, currently targeted for early 2028.
Does Signing the Accords Change Serbia’s China Space Ties?
It does not. The Artemis Accords contain no provisions requiring signatories to limit space cooperation with non-signatory countries. Russia and China’s exclusion from the framework — Russia by choice, China by U.S. Congressional restriction on NASA bilateral cooperation — does not prevent their partner nations from continuing joint programs. Thailand and Senegal are both Artemis signatories and ILRS participants simultaneously.
What it does is add a layer of U.S. diplomatic relationships and potential future access to Artemis program activities to Serbia’s existing portfolio of space partnerships.
How Serbia Fits Into the Artemis Accords Architecture
Serbia’s signing adds a southeastern European voice to a coalition now covering every inhabited continent. Most directly comparable recent signatories are neighbors like Slovenia (2024), Hungary (2025), and — notably — Romania (2022), all Balkan or Central European countries that have signed as part of EU-adjacent space diplomacy.
What distinguishes Serbia is that none of those countries are simultaneously running a satellite program built by a Chinese state entity. Serbia’s Mozaik partnership with DFHSat/CAST makes it, at the moment of signing, the Artemis Accords signatory with the most active and substantive Chinese space technology dependency.
Whether that tension resolves over time — or whether it becomes the template for how small nations navigate the era of bifurcated space frameworks — is the question that Serbia’s Artemis signing actually poses.
Frequently Asked QuestionsWhat exactly does Serbia commit to by signing the Artemis Accords?
Serbia commits to nine non-binding principles: peaceful civil space exploration, transparency about its national space activities, interoperability of systems, emergency assistance to any personnel in distress in space, open sharing of scientific data, resource extraction consistent with the Outer Space Treaty, orbital debris mitigation, preservation of historic sites in space, and coordinating operations through “safety zones” to avoid harmful interference with other nations’ activities. Because the Accords are not a treaty under the UN Charter’s Article 102 framework, there is no enforcement mechanism, no dispute resolution process, and no legal consequence for non-compliance. Signing does not obligate Serbia to contribute hardware or funding to any specific Artemis mission.
If Serbia is joining an American-led space framework, why is China building its first satellite?
Because the Artemis Accords do not prohibit signatories from cooperating with non-signatory countries in space, and Serbia’s official policy is multi-vector alignment with all major powers simultaneously. The Mozaik satellite is being built with a platform from DFHSat, a subsidiary of China’s national space authority (CAST), with Chinese partners providing the satellite platform, technical expertise, and launch support. This makes Serbia the Artemis Accords signatory with the most active and substantive Chinese space technology dependency at the moment of signing — a structural tension the U.S. has not publicly addressed and the Accords do not resolve.
What is the difference between the Artemis Accords and the competing International Lunar Research Station framework?
The Artemis Accords are a set of bilateral agreements drafted by NASA and the U.S. State Department, signed individually by each country with the United States, that establish norms for civil space exploration. The ILRS is a China-Russia framework offering an alternative governance model for lunar activities. Critics of the Accords argue the bilateral structure effectively lets the United States set rules for a global commons without multilateral negotiation through the UN Committee on the Peaceful Uses of Outer Space. Two countries — Thailand and Senegal — have signed both frameworks, making them the live test cases for whether the two systems can coexist.
When is the first crewed Moon landing actually planned?
Artemis III, currently scheduled for late 2027, has been redesigned as a low-Earth-orbit docking test for SpaceX’s Starship and Blue Origin’s Blue Moon lander — not a lunar landing. The first planned crewed Moon landing under the Artemis program is now Artemis IV, targeted for early 2028.
