摘要：Orbital space debris is created when an orbiting space object or part of a space object is no longer functioning. Examples include fragments produced by a satellite launcher upper stage (“ rocket body”) explosion, typically caused by residual on-board energetic propellants. In most Earth orbital regions, orbiting space debris created as a by-product of space activities remains in orbit for a long period of time (typically more than 25-50 years).
