But the rest could best be called junk, the by-product of thousands of launches and routine spacecraft deployments, nearly 200 explosions, and several collisions. And this junk poses a serious problem. Many years ago, early orbital debris researchers predicted that parts of Earth’s orbit could eventually become so crowded that accidental collisions would fuel a self-reinforcing boom in the hazardous debris population—even if we put a stop to future launches.
