3. 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 the 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 justified, for example, by the provisions of
the United Nations treaties and principles on outer space.
4. 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:
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 profile 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
73
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 identified. 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.
Guideline 4: Avoid intentional destruction and other harmful activities
Recognizing that an increased risk of collision could pose a threat to space
operations, the intentional destruction of any on-orbit spacecraft and launch vehicle
orbital stages or other harmful activities that generate long-lived debris should be
avoided.
When intentional break-ups are necessary, they should be conducted at
sufficiently low altitudes to limit the orbital lifetime of resulting fragments.
Guideline 5: Minimize potential for post-mission break-ups resulting from stored
energy
In order to limit the risk to other spacecraft and launch vehicle orbital stages
from accidental break-ups, all on-board sources of stored energy should be depleted
or made safe when they are no longer required for mission operations or post
mission disposal.
By far the largest percentage of the catalogued space debris population
originated from the fragmentation of spacecraft and launch vehicle orbital stages.
The majority of those break-ups were unintentional, many arising from the
abandonment of spacecraft and launch vehicle orbital stages with significant
amounts of stored energy. The most effective mitigation measures have been the
passivation of spacecraft and launch vehicle orbital stages at the end of their
mission. Passivation requires the removal of all forms of stored energy, including
residual propellants and compressed fluids and the discharge of electrical storage
devices.
Guideline 6: Limit the long-term presence of spacecraft and launch vehicle orbital
stages in the low-Earth orbit (LEO) region after the end of their mission
Spacecraft and launch vehicle orbital stages that have terminated their
operational phases in orbits that pass through the LEO region should be removed
from orbit in a controlled fashion. If this is not possible, they should be disposed of
in orbits that avoid their long-term presence in the LEO region.
When making determinations regarding potential solutions for removing
objects from LEO, due consideration should be given to ensuring that debris that
survives to reach the surface of the Earth does not pose an undue risk to people or
property, including through environmental pollution caused by hazardous
substances.
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 the operation of
newly designed spacecraft and orbital stages and, if possible, to existing ones. They
