ESA Open Day is a public space open day scheduled for 19-20 September 2026 at ESA Headquarters in Paris, France.

For families and public visitors, students and educators, ESA Open Day offers specialist subjects in the context of the organisations, systems and decisions that use them.
ESA Open Day also creates useful links between public space outreach and eSA missions, two areas that often need to be considered together in real projects.
