The space debris crisis, the Kessler disaster, and the future of orbital cleanup

As we gaze at the night sky, we might imagine it as a clear, empty expanse, but the reality is that Low Earth Orbit (LEO) is dangerously crowded. Thousands of satellites, both operational and inactive, along with millions of small pieces of debris, orbit Earth at extremely high speeds. This "space junk" has become a pressing global security and environmental problem, threatening to cripple the vital infrastructure we rely on daily for communication, navigation, and weather forecasting. Scientific risk analysis points to a terrifying scenario known as Kessler Syndrome. According to this model, the density of objects in space will one day become so high that a single accidental collision between two pieces will generate a cloud of debris, which will then collide with other satellites, creating a chain reaction. This interaction could render LEO unusable for decades, potentially isolating humanity from space. The 2009 collision between the Iridium communications satellite and t…
