ESTEC OPEN DAY 2026: SAVE THE DATE!

We’re delighted to announce that Space Rocks will be back at ESA’s Open Day at ESTEC – the technical heart of the European Space Agency. This year’s event will take place a week earlier than usual on 26-27 September 2026. It’s also the 15th anniversary of the ESTEC Open Day so it promises to be extra special.

For a taste of what goes on at the Open Day, we’ve produced this 30-minute programme featuring all the sights and sounds of last year’s event. 

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?

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.
