Researchers introduce the CRASH Clock to estimate how long low Earth orbit could remain safe if satellites could no longer dodge each other; the margin fell from 164 days in 2018 to 5.5 days in 2025 as megaconstellations expanded, underscoring that LEO is now an infrastructure-like shared space requiring continuous coordination, accurate tracking, and robust data to prevent a rapid cascade of near-misses.
A new arXiv study introduces the CRASH Clock to estimate how quickly a major satellite collision could occur if orbital tracking or maneuvering fails. Results show a serious collision could happen in about 2.8 days if maneuvering is lost (5.5 days when all tracked objects are included), a sharp tightening from 164 days in 2018 due to denser mega-constellations and debris. The risk is amplified by solar storms that disrupt tracking, communications, and maneuvering, potentially triggering a rapid cascade of debris in low Earth orbit.
New research introduces the CRASH Clock to estimate how quickly a serious, debris-generating collision could occur in crowded low-Earth orbit if satellites lose control; using June 2025 data, a loss of command for avoidance could trigger a catastrophic collision in about 2.8 days, with a broader version at 5.5 days and a far longer 164-day gap in 2018. The risk is heightened by megaconstellations such as Starlink, which perform thousands of maneuvers, and by solar storms that expand Earth's atmosphere and disrupt tracking, making collision assessments harder and potentially leading to rapid debris growth in a Carrington-scale event.
Scientists warn that a powerful solar storm could abruptly trigger a Kessler syndrome–style cascade in Earth's low orbit, turning orbital debris into a self-perpetuating cloud that endangers satellites and could shower debris back to Earth. Researchers introduced the CRASH clock, suggesting a catastrophic collision could unfold in roughly 5.5 days if navigation is disrupted, a sobering risk given the growing megaconstellations from SpaceX, Amazon, and others and the current high rate of in-orbit maneuvers.
A new 'CRASH Clock' study warns that in a worst-case scenario, Earth-orbiting satellites could start colliding within less than three days, a significant decrease from previous estimates, driven by the rapid increase in satellite numbers and potential space weather events, raising concerns about space debris and the Kessler Syndrome.
A new study introduces the CRASH clock, indicating a 2.8-day window before a likely catastrophic collision in low-Earth orbit due to increasing satellite congestion, especially from Starlink, raising concerns about potential Kessler syndrome and the need for immediate action to prevent space debris chaos.
