AI Insight
A new CRASH clock has been developed to measure the probability of satellite collisions in orbit. The clock highlights the growing risk of space debris impacts, where even small debris traveling at approximately 10 kilometers per second can deliver catastrophic energy equivalent to 2 kilograms of TNT upon collision with satellites like those in the Starlink constellation. The increasing number of satellites and debris in orbit is accelerating the countdown on this collision risk assessment tool.
Why it matters
This collision risk assessment is critical for the rapidly expanding satellite industry and space operations, as the proliferation of mega-constellations like Starlink increases collision probabilities. Understanding and tracking these risks is essential for developing mitigation strategies, informing space traffic management policies, and preventing cascading debris events that could render certain orbital regions unusable.
Understand the Science
Imagine a piece of space debris the size of a hockey puck slams into a Starlink satellite at about 10 kilometers per second. The kinetic energy is equivalent to 2 kilograms of TNT, or a fully loaded semitruck traveling at 100 kilometers an hour.
