Each crater tells a story — of dramatic collisions, planetary transformation, and extinction events. Some shaped landscapes. Others reshaped life itself. That’s why we study asteroids. Because understanding the past helps us protect the future. We’re working on planetary defence through: - Finding new asteroids and measuring their orbits - Developing new asteroid-hunting telescopes like Flyeye - Sending spacecraft like Hera to asteroids to test asteroid deflection - Coordinating humankind’s asteroid response at unoosa Swipe through to explore Earth’s cratered history, captured by our astronauts from the iss and by satellites like the copernicus_eu Sentinel-2 mission. Happy asteroidday! And yes… we do want to close our eyes and not miss a thing — especially when it comes to spotting potentially ...
