A Ton of Space Junk Is Reentering Earth’s Atmosphere More Often, and It’s Hard to PredictUncontrolled reentries of 500-kg-plus objects occur weekly, yet prediction errors span thousands of kilometers and no binding rules existAl Landes, Jul 31, 2026, https://www.gadgetreview.com/a-ton-of-space-junk-is-reentering-earths-atmosphere-more-often-and-its-hard-to-predictKey TakeawaysUncontrolled space debris weighing up to 2,000 kilograms reenters Earth’s atmosphere weekl y.y. Objects weighing 500 to 2,000 kilograms reenter Earth’s atmosphere uncontrolled roughly every week, according to ESA and a 2024 peer-reviewed hazard study. The Numbers Are Bigger Than You ThinkThe scale of uncontrolled reentries dwarfs what most people assume — and the pace is rising. — Holger Krag, Head of ESA’s Space Debris OfficeThose few hours matter enormously. Hazard analyses suggest uncontrolled reentries likely breach that threshold weekly, often without national authorities even registering it.
