Fragile Orbits: Could a Debris Cascade Spin Out of Control?
The Guardian piece explains Earth’s orbit is now a crowded, evolving space: about 32,000 objects are currently tracked, with private mega‑constellations like Starlink driving a rapid rise in satellites and debris. Projections suggest as many as 60,000 active satellites by the end of the decade. A collision cascade—where one crash produces fragments that collide with more satellites—could rapidly worsen conditions, potentially making launches dangerous and the orbital environment unsustainable. Experts like Jonathan McDowell warn the system is fragile and hinges on continuous cooperation; deorbiting, nets, lasers and stronger space governance are being explored to avert a debris catastrophe.
