The European Space Agency reports that its Open Days 2026 welcomed over 23 000 visitors across its six establishments. According to ESA, the events gave the public a chance to learn more about Europe's space activities, meet the people behind the missions and explore how the agency is shaping the future of space.

The figures and details come from an ESA video item published on 21 October 2026, which is the source's stated publication date. The agency notes that the video includes third-party content and may not be modified, and that its footage, animations and music may not be reused in other productions without explicit authorisation.

The summary is based solely on the agency's own account of the events; no further breakdown of visitor numbers by location was provided in the source text.
