ESA Open Days
Your chance to meet the European Space Agency
Every year, the European Space Agency opens its doors to thousands of visitors from across the continent. At our Open Days, you won't just visit our establishments - you'll step inside the world of European space exploration. Get up close to our missions, meet the people behind them, and discover firsthand what it truly takes to reach beyond our planet.
Our mission is to bring space closer to people. To spark imagination, deepen curiosity, and build connections across Europe. To show what space means for our shared prosperity, our technological ambitions — and the generation that will carry our continent forward.
