Synopsis
In the document, the Space Bureau seeks to refresh the record on
rule changes pertaining to orbital debris mitigation previously
proposed by the Commission. The Commission continues to seek to improve
and clarify its rules taking into account the Commission's experience
gained in the satellite licensing process, improvements in mitigation
guidelines and practices, and in light of various market developments.
The Commission sought comment in a 2020 FNPRM on various proposals for
amending the Commission's orbital debris mitigation rules (85 FR 52455,
Aug. 25, 2020). The comment period closed over three years ago in 2020.
To ensure that the Commission has the benefit of current information,
including any developments relating to these issues since the release
of the underlying FNPRM, the Commission invites interested parties to
update the record as discussed in the document.
Background. In 2020, the Commission adopted a Report and Order
(2020 Order) comprehensively updating its rules on orbital debris
mitigation (85 FR 52422, Aug. 25, 2020). At the same time, the
Commission adopted the FNPRM which sought comment on additional rule
amendments and proposals related to the probability of accidental
explosions, collision risk for multi-satellite systems, maneuverability
requirements, and casualty risk, among other issues. In the 2020 Order,
the Commission discussed the pace at which the industry is growing,
noting that it expected that the regulation of orbital debris would be
an iterative process as new research becomes available and new policies
are developed based on experience and the evolving commercial space
landscape.
Since the Commission last sought comment on its orbital debris
mitigation rules, NASA and other standards-setting bodies have made a
number of technical and policy updates to their orbital debris
mitigation standards and guidance documents, and industry has gained
substantial experience in this area, potentially leading to the
development or refinement of new industry standards and practices in
the future. In addition, in order to maintain U.S. leadership in the
space economy, the Commission has opened a new docket for Space
Innovation, IB Docket 22-271, recognizing that the new space age needs
new rules, including for orbital debris mitigation, that reflect the
expanding proliferation of satellites and innovations in the space
industry. Finally, the Space Bureau's own experience in satellite
licensing and addressing associated orbital debris concerns has also
advanced and parties have provided additional views in specific
licensing proceedings on approaches to debris mitigation, particularly
for large constellations.
Based on these considerations, the document provides an opportunity
for additional comments in order to ensure an up-to-date record.
Request for Additional Comment. Accordingly, the Space Bureau
invites stakeholders to update the record after reviewing the specific
proposals, underlying analysis, and questions contained in the FNPRM,
as well as the existing record in this proceeding. In particular, the
FNPRM presented a number of questions and proposals regarding the
debris mitigation practices for constellations, including specific
considerations related to the total probability of collisions with
large objects.
In this context, the Commission sought comment on whether it should
analyze collision risks based on the entire system (system-wide, or in
the aggregate) or on individual satellites (per-satellite) within a
multi-satellite non-geostationary orbit (NGSO) system. If the
Commission were to opt for a system-wide approach, it sought comment on
the process through which such collision risks should be considered and
what factors would be relevant in performing such an analysis. The
Commission noted that, if it adopted a system-wide safe harbor
approach, systems that are able to demonstrate that they meet a system-
wide collision probability metric (or another suitable risk indicator)
would be considered as adequately addressing this aspect of debris
mitigation, but systems that exceed the threshold would be subject to
further review. The Commission sought comment on using the U.S. Orbital
Debris Mitigation Standard Practices' (ODMSP) 0.001 probability of
collision metric as a threshold or safe harbor as a means of
identifying systems that may need further review. The Commission sought
comment on whether a safe harbor approach like the one described above
or a bright-line rule would be preferable in this context and asked for
specific metrics or thresholds that would be appropriate for each
scenario.
The Commission also identified several factors that could be
relevant in establishing a safe harbor or bright-line rule, the
maneuvering capabilities and reliability of the satellite(s), orbital
lifetime, the number of satellites in the system (possibly including
constellation replenishment rate and replacement satellites over some
specific time period), and the size of individual satellites. The
Commission sought comment on if these factors were relevant for
consideration in this regard, how these factors should be evaluated,
and whether there were any more factors that should be considered. As
it pertains to large constellations, the Commission asked for input on
whether it should make a bright-line distinction between large
constellations and smaller systems in terms of the applicable metrics
for collision risk assessment, or should it attempt to specify a
scalable metric for both types of systems.
The Space Bureau seeks to refresh the record on these points. In
particular, in several ex parte presentations, commenters addressed a
possible metric of 100 ``object-years'' for assessing the risks that
may arise if satellites fail to complete planned disposal. ``Object-
years'' refers to the number of years each failed satellite would
remain in orbit, summed across any other failed satellites that were
part of the satellite system. The Space Bureau seeks comment on this
and other approaches for addressing the reliability of post mission
disposal, especially for constellations. Is an object-years metric
suitable for this type of analysis, and if so, what threshold should be
applied? The Space Bureau has used a 100 object-years metric in some
licenses as a trigger for cases in which disposal failures would
warrant additional Commission review of the execution of debris
mitigation measures, and it seeks comment on whether this approach
should be utilized more or less widely, and in which types of cases.
Are there alternative approaches for identifying which systems may pose
more collision risk than others? The Space Bureau asks for comment on
such approaches, as well as any potential alternative metrics, methods
for risk analysis, or implementation strategies for managing these
collision risks, especially as it pertains to larger systems.
Additionally, it seeks comment on appropriate actions should an
operator be granted a license and then exceed a 100 object-year
threshold, or any other metric that may be adopted. For example, should
the operator be required to cease satellite deployment until the causes
of the disposal failure have been identified and addressed
sufficiently? If a cause and solution have been identified and
successfully implemented, should the count of object years be re-set by
removing object-years for those satellites from the operator's total
object years? Are there other reporting conditions that could be used
to address collision risks?
[[Page 46054]]
The Space Bureau recognizes that many factors, including orbital
altitude and maneuvering capabilities, may impact collision risk
analyses. In the FNPRM, the Commission was specifically interested in
understanding the role of maneuvering capabilities in mitigating
collision risk and the extent to which their reliability should be
factored into collision risk assessments. The Commission sought comment
on how to evaluate the likelihood of individual satellite maneuvering
failures within a multi-satellite system. Additionally, the Commission
requested input on how to assess the collision risk associated with
failed satellites, including what the assumed location of the
maneuvering failure should be (i.e., in the deployment orbit, the
worst-case collision risk orbit, a combination of both, or a range of
orbits representing the expected range and duration of satellite
operations), and if there are any methods by which the Commission could
apply historical data concerning the typical point in a satellite
mission where failures occur in order to refine the analysis. The FNPRM
requested comment on this approach and on other alternatives for
assessing an expected failure rate on a more detailed basis. The Space
Bureau now requests additional comment on these issues, especially how
they relate to mitigating collision risks with large objects.
In the event a safe harbor approach is adopted, the FNPRM sought
comment on the review process for systems that did not meet the
established safe harbor criteria. The Commission invited comment on
options such as allowing applicants to demonstrate a lower actual
failure rate for their maneuvering capabilities than the assumed rate
used in the safe harbor assessment. For larger systems with multiple
deployments, the Commission also asked commenters to provide feedback
on the possibility of implementing a license condition requiring the
applicant to provide additional demonstrations if the actual failure
rate for the initial deployments is substantially higher than the
expected failure rate expressed in its application.
For NGSO systems that could not meet the safe harbor, if adopted,
the FNPRM also sought comment on other aspects of a more detailed
review process, such as asking operators to provide additional detail
on alternative satellite designs that were considered during
development or additional measures that will be taken to reduce the
total collision risk. To this end, the Commission sought input on what
additional measures may correlate with lower risk and if there were
specific measures that can be specified with a goal of minimizing the
need for a case-by-case approach.
The Space Bureau encourages interested parties to submit new or
additional relevant information related to these and other questions
laid out in the FNPRM, as well as information about the present state
of the orbital debris environment and the satellite industry at large,
including the types of mission profiles or additional considerations
that may have arisen with more prominence since the FNPRM was first
adopted. The Space Bureau recognizes that the satellite industry is
rapidly evolving, and that issues or concerns may have arisen that were
not expressly considered at the time the FNPRM was adopted, or that
stakeholders now feel have otherwise rendered some of the initial
considerations and proposals in the FNPRM obsolete or infeasible.
Accordingly, the Space Bureau invites interested parties to provide
additional specific recommendations or alternative proposals, supported
by relevant experience and source material that may not have been
available prior to the release of the document, as it pertains to the
issues raised here and presented in the FNPRM.
