First International Space Summit Opens in Paris Amid US No-Shows

By the Editorial Team · Friday, September 11, 2026

The International Space Summit launched in Paris, bringing together around 2,000 global leaders and experts to discuss space exploration, policy, and security over two days. The event is marked by the notable absence of major U.S. space firms, reportedly due to White House advice, highlighting underlying political tensions amid efforts to promote international collaboration.

The inaugural International Space Summit commenced Wednesday in Paris, gathering a diverse group of leaders, scientists, astronauts, and industry figures to discuss wide-ranging aspects of space exploration and policy. Initiated by French President Emmanuel Macron and co-hosted by France and Germany, the two-day event is expected to draw approximately 2,000 participants.

The summit’s agenda covers several key areas, including scientific research and exploration initiatives such as missions to Mars, ocean observation, and broader space science. Additionally, discussions are set to address the emerging global space economy, focusing on issues such as access to space, connectivity, industrial growth, and Europe’s competitiveness in the sector. Another significant theme is space security and governance, reflecting increasing concerns about regulatory frameworks and the peaceful use of outer space.

Despite the high-profile nature of the event, it has been marked by notable absences from major U.S. space companies. Reports indicate that Blue Origin, SpaceX, Stoke Space, and Starcloud withdrew their participation ahead of the summit. According to media sources, the White House influenced this decision, reportedly advising U.S. firms to avoid the event to prevent their attendance from being perceived as endorsement of European Union policy positions.

The withdrawal of these leading U.S. companies has introduced a layer of transatlantic tension to the summit, overshadowing the collaborative spirit expected at an international gathering aimed at fostering cooperation in space endeavors. Organizers remain focused on advancing discussions on shared challenges and opportunities in space, despite the political undercurrents that have affected participation.

As the summit proceeds, stakeholders from across government, industry, and the scientific community are expected to contribute to shaping future space policies and partnerships, with an emphasis on fostering innovation and ensuring security in an increasingly crowded orbital environment.
