Earth orbit is becoming increasingly crowded. With over 11 000 active satellites and many thousands more expected in the coming years as well as over 1.2 million pieces of space debris greater than 1 cm, the risk of in-orbit collisions has turned into a daily operational concern. ESA is investing in automation technologies that can help satellite operators respond more effectively to collision risks.
