loss of mission, or loss of life in the case of manned spacecraft. For manned fl ight orbits, space debris mitigation measures are highly relevant due to crew safety implications. A set of mitigation guidelines has been developed by the Inter-Agency Space Debris Coordination Committee (IADC), refl ecting the fundamental mitigation elements of a series of existing practices, standards, codes and handbooks developed by a number of national and international organizations. The Committee on the Peaceful Uses of Outer Space acknowledges the benefi t of a set of high-level qualitative guidelines, having wider acceptance among the global space community. The Working Group on Space Debris was therefore established (by the Scientifi c and Technical Subcommittee of the Committee) to develop a set of recommended guidelines based on the technical content and the basic defi nitions of the IADC space debris mitigation guidelines, taking into consideration the United Nations treaties and principles on outer space. APPLICATION Member States and international organizations should voluntarily take measures, through national mechanisms or through their own applicable mechanisms, to ensure that these guidelines are implemented, to the greatest extent feasible, through space debris mitigation practices and procedures. These guidelines are applicable to mission planning and operation of newly designed spacecraft and orbital stages and, if possible, to existing ones. They are not legally binding under international law. It is also recognized that exceptions to the implementation of individual guidelines or elements thereof may be justifi ed, for example, by the provisions of the United Nations treaties and principles on outer space. SPACE DEBRIS MITIGATION GUIDELINES The following guidelines should be considered for the mission planning, design, manufacture and operational (launch, mission and disposal) phases of spacecraft and launch vehicle orbital stages: 129
130 Guideline 1: Limit debris released during normal operations Space systems should be designed not to release debris during normal operations. If this is not feasible, the effect of any release of debris on the outer space environment should be minimized. During the early decades of the space age, launch vehicle and spacecraft designers permitted the intentional release of numerous mission-related objects into Earth orbit, including, among other things, sensor covers, separation mechanisms and deployment articles. Dedicated design efforts, prompted by the recognition of the threat posed by such objects, have proved effective in reducing this source of space debris. Guideline 2: Minimize the potential for break-ups during operational phases Spacecraft and launch vehicle orbital stages should be designed to avoid failure modes which may lead to accidental break-ups. In cases where a condition leading to such a failure is detected, disposal and passivation measures should be planned and executed to avoid break-ups. Historically, some break-ups have been caused by space system malfunctions, such as catastrophic failures of propulsion and power systems. By incorporating potential break-up scenarios in failure mode analysis, the probability of these catastrophic events can be reduced. Guideline 3: Limit the probability of accidental collision in orbit In developing the design and mission profi le of spacecraft and launch vehicle stages, the probability of accidental collision with known objects during the system’s launch phase and orbital lifetime should be estimated and limited. If available orbital data indicate a potential collision, adjustment of the launch time or an on-orbit avoidance manoeuvre should be considered. Some accidental collisions have already been identifi ed. Numerous studies indicate that, as the number and mass of space debris increase, the primary source of new space debris is likely to be from collisions. Collision avoidance procedures have already been adopted by some Member States and international organizations.
