A History of Space Debris Impacts on the ISS and ISS Conjunction Avoidance Actions
Since its launch, the International Space Station has endured a continuous barrage of orbital debris, with tiny, untracked particles responsible for the majority of documented hardware damage. While NASA conducts collision‑avoidance burns when the calculated risk exceeds a 1 in 10,000 chance, the frequency of such maneuvers spiked after the 2007 Fengyun‑1C anti‑satellite test and the 2021 Kosmos 1408 breakup. A database of 380 micrometeoroid and orbital‑debris (MMOD) strikes reveals impacts on windows, thermal blankets, radiators, handrails, and even the Canadarm2, underscoring the need for layered protection, safe‑haven procedures, and disciplined operations. The recent probable MMOD strike that disabled Soyuz MS‑22 illustrates how even non‑catastrophic hits can reshape crew‑rotation plans and launch schedules.
