Paris Hosts First-Ever International Space Summit to Highlight Europes Cooperative Space Strategy
On the eve of the 2026 space race, Paris will host a gathering that could reshape how nations reach for the stars. The International Space Summit, set for September 9‑10 at the Grand Palais, will convene delegations from 120 countries, European Union officials, and industry leaders. The event, convened by French President Emmanuel Macron, marks the first of its kind and will feature a keynote address from European Commission President Ursula von der Leyen.
The summit’s central theme is Europe’s evolving approach to space sovereignty, framed by a research report that identifies a shift toward multilateral “coopetition.” This model blends cooperation and competition among states, agencies, and companies and underpins flagship programmes such as Galileo, Copernicus, Clean Sky, and the forthcoming IRIS² satellite constellation.
Concrete examples of coopetition are already underway. French firm Thales Alenia Space and Germany’s OHB System are jointly developing radar instruments for the European Space Agency’s (ESA) Harmony mission, which monitors changes in Earth’s shape. Dassault Aviation and OHB System have teamed up to propose the VORTEX‑S multipurpose space plane to ESA. These partnerships illustrate a broader strategic shift: rather than vying for sovereignty, European players are building it together.
The research outlines three key benefits of this cooperative model. First, it brings together a critical mass of technical and financial resources that no single actor could muster alone. Second, it enables the exchange of heterogeneous, complementary knowledge essential for complex projects. Third, it distributes high‑risk, long‑term innovation costs across multiple partners, thereby reducing individual exposure.
ESA occupies a dual role in this ecosystem. As programme owner, the agency provides financing and sets specifications; as a technical prime contractor, it steers satellite development. In the Galileo navigation system, for instance, competing manufacturers were reluctant to share proprietary data directly. ESA collected and redistributed the necessary knowledge, allowing the constellation’s construction to proceed.
Managing multilateral coopetition requires both formal governance mechanisms and informal trust. The €5 billion Clean Sky programme, aimed at cutting aircraft emissions, involves eleven competitors who coordinate through a Network Management Office. While contracts and intellectual‑property rules establish the framework, daily interactions and shared professional norms build the trust needed for sensitive knowledge exchange.
Europe’s space ambitions are further framed by France’s National Space Strategy 2025‑2040, which calls for a more integrated framework to strengthen cooperation across civilian, dual‑use, and military domains. The strategy aligns with the European Union’s broader space policy objectives and supports the development of a sovereign communications infrastructure through IRIS².
According to the research, global space spending reached a record $137 billion in 2025, a figure announced at France’s 14th Perspectives spatiales conference. This level of investment underscores the intensity of competition and the structural reality that mastering the entire space value chain is beyond the reach of any single state, agency, or company.
The International Space Summit will provide a platform for stakeholders to discuss how these cooperative models can be scaled, how ESA can continue to orchestrate complex programmes, and how Europe can maintain strategic autonomy amid increasing rivalry among EU member states and global competitors.
In conclusion, the Paris summit marks a milestone in Europe’s space policy, emphasizing that sovereignty in space will be achieved through collaboration rather than isolation. The event will likely set the agenda for upcoming programme launches, regulatory discussions, and further investment decisions as Europe prepares to navigate the next phase of the space race.
