Space junk, also known as orbital debris, consists of millions of defunct human-made objects and nature particles orbiting our planet. This includes non-functional satellites, rocket stages, fragments from satellite collisions or explosions, and even tiny paint flecks shed from spacecraft surfaces. Although these pieces no longer serve any purpose, they continue to travel at incredibly high speeds, often exceeding 17,000 miles per hour, posing a significant risk to operational satellites, the International Space Station, and future space missions. Collisions involving space junk can generate even more debris, creating a cascading effect known as the Kessler Syndrome, which could severely hinder safe access to space and the Earth’s health. Understanding space junk is the first step toward ensuring the long-term sustainability of space activities and protecting the vital infrastructure orbiting above us.
