More than 30,000 objects are currently tracked in Earth orbit. Over half are debris. An estimated one million additional pieces — too small to track, large enough to disable a satellite — occupy the same shells of space that underpin GPS, weather forecasting, financial transactions, and military communications. The problem is not hypothetical. It is measurable, accelerating, and approaching thresholds that some experts believe are irreversible. The GAO’s 2026 horizon report documents the trajectory with data.
