SPACE ROCKS AT THE ESTEC OPEN DAY 2025
The ESTEC Open Day is a truly unique opportunity for the public to get a front row seat to the final frontier at the technical heart of the European Space Agency.
From astronauts to astrophysicists, to composers and Alien ovomorphs, there’s simply no other event like it, but how did the Open Day begin? And what’s next for space exploration?
We’ve got the answer to that and more in our special programme dedicated to the past, the present, and the future of European innovation as ESA celebrates the 50th anniversary of its founding.
The ESTEC Open Day takes place in Noordwijk in the Netherlands. It’s open to all and free to attend. The 2026 event will take place on Sunday, September 27th with a special accessibility day taking place on Saturday, September 26th.
