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，主要与因不受控制的重返大气层以及在轨碰撞对人群造成的风险有关；此类碰撞可能会损毁非常珍贵的卫星，但也会产生新的碎片群，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，国际层面已制定了一套标准，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，这就要求所有太空行为体迅速采取并协调新的行动，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。
