Introduction Space debris comprises all non-functional, man-made objects, including fragments and elements thereof, in Earth orbit or re-entering the Earth's atmosphere. The growing population of these objects poses an increasing hazard to missions. In response to this problem, there is international consensus that space activities need to be managed to minimize debris generation and risk. This consensus is embodied in space debris mitigation guidelines published by organizations such as the International Telecommunication Union (ITU) [1], the Inter-Agency Space Debris Coordination Committee (IADC) [2][3] and the United Nations (UN) [4]. The transformation of debris mitigation guidelines into engineering practice is a key purpose of this International Standard. The importance of this International Standard can be seen within the context of four UN treaties [5] that were established under the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS) to govern the involvement of nations in space activities. These are the Outer Space Treaty, the Liability Convention, the Registration Convention and the Rescue Agreement. Through some of these treaties, a Launching State has total liability for damage caused by its spacecraft or launch vehicle orbital stages (or any parts thereof) on the surface of the Earth or to aircraft in flight, as well as in outer space where fault can be proven. All countries are encouraged to abide by these international agreements in order not to endanger or constrain existing and future space missions. A Launching State can choose to appoint licensing or regulatory authorities to administer its approach for complying with the above-mentioned UN treaties. In several Launching States, these authorities have implemented national legislation to enforce the UN treaties. Such legislation can include the mitigation of space debris. Some Launching States meet their obligations by appointing non-regulatory government bodies, such as national space agencies, to provide the necessary guidelines or requirements, including those for space debris mitigation. The general aim of space debris mitigation is to reduce the growth of space debris by ensuring that spacecraft and launch vehicle orbital stages are designed, operated and disposed of in a manner that prevents them from generating debris throughout their orbital lifetime. This is achieved by the following actions: a) avoiding the intentional release of space debris into Earth orbit during normal operations; b) avoiding break-ups in Earth orbit; c) removing spacecraft and launch vehicle orbital stages from protected orbital regions after end of mission; d) performing the necessary actions to minimize the risk of collision with other space objects. Such actions are especially important for a spacecraft or launch vehicle orbital stage that has one or more of the following characteristics: a large collision cross-section; remains in orbit for many years; operates near manned mission orbital regions; operates in highly utilized regions, such as protected regions; operates in regions of high debris population. This International Standard transforms these objectives into a set of high-level debris mitigation requirements. Methods and processes to enable compliance with these requirements are provided in a series of lower-level implementation standards. ISO 2011 All rights reserved v
