The rapid evolution of the number of orbital debris since the beginning of the space age raises numerous problems today, mainly linked to the risk to populations due to uncontrolled atmospheric reentries, and to on-orbit collisions; such collisions may kill very precious satellites, but also regenerate swarms of new debris potentially triggering an ever increasing number of space objects in the coming years. To counter these projections, a set of standards has been prepared at international level, but it is far from being properly complied to, yet. The upcoming new space activities, “Space 4.0”, with the foreseen launch of thousands of new satellites, imposes new actions to be taken rapidly, coordinated among all space actors, in order to guarantee a sustainable evolution of the orbital activities, so vital in our daily lives for environment, telecommunications, navigation, aso.
自太空时代开始以来，轨道碎片数量的迅速增长如今引发了诸多问题，主要涉及因不受控制的大气再入以及在轨碰撞对人类造成的风险；此类碰撞可能致使非常珍贵的卫星报废，还会产生大量新的碎片群，有可能在未来几年引发越来越多的太空物体。为应对这些预测情况，国际层面已制定了一系列标准，但目前仍远未得到妥善遵守。即将到来的新太空活动“太空4.0”，预计将发射数千颗新卫星，这就要求迅速采取新行动，并在所有太空行为体之间进行协调，以确保轨道活动的可持续发展，而轨道活动在我们日常生活中的环境、电信、导航等方面至关重要。
