“…We focus on long-run orbit use by competitive satellite operators. 3 As such, we abstract from the details of orbital-use dynamics and focus on two properties of orbit use established in Somma, Lewis and Colombo (2019), Lewis (2020), and Rao and Rondina (2022). First, the long-run collision risk is a function of the long-run launch rate, with higher launch rates implying greater collision risk.…”

Orbit-use management efforts can be structured as binding national regulatory policies or as self-enforcing international treaties. New treaties to control space debris growth appear unlikely in the near future. Spacefaring nations can pursue national regulatory policies, though regulatory competition and open access to orbit make their effectiveness unclear. We develop a game-theoretic model of national regulatory policies and self-enforcing international treaties for orbit-use management in the face of open access, regulatory competition, and catastrophe. While open access limits the effectiveness of national policies, market-access control ensures the policies can improve environmental quality. A large enough stock of legacy debris ensures existence of a global regulatory equilibrium where all nations choose to levy environmental regulations on all satellites. The global regulatory equilibrium supports a self-enforcing treaty to avert catastrophe by making it costlier to leave the treaty and free ride.

“…When the satellite is transferring its orbit, the change of orbit altitude should be limited to a reasonable range to ensure the stable operation of the satellite. As the satellite altitude is typically between 250 and 1300 km [43], constraint (28) is carried out to limit the satellite altitude after maneuvering. Constraint ( 29) is used to ensure that the observation moment lies in the sunshine time window.…”

Earth observation satellite (EOS) systems often encounter emergency observation tasks oriented to sudden disasters (e.g., earthquake, tsunami, and mud-rock flow). However, EOS systems may not be able to provide feasible coverage time windows for emergencies, which requires that an appropriately selected satellite transfers its orbit for better observation. In this context, we investigate the orbit maneuver optimization problem. First, by analyzing the orbit coverage and dynamics, we construct three models for describing the orbit maneuver optimization problem. These models, respectively, consider the response time, ground resolution, and fuel consumption as optimization objectives to satisfy diverse user requirements. Second, we employ an adaptive differential evolution (DE) integrating ant colony optimization (ACO) to solve the optimization models, which is named ACODE. In ACODE, key components (i.e., genetic operations and control parameters) of DE are formed into a directed acyclic graph and an ACO is appropriately embedded into an algorithm framework to find reasonable combinations of the components from the graph. Third, we conduct extensive experimental studies to show the superiority of ACODE. Compared with three existing algorithms (i.e., EPSDE, CSO, and SLPSO), ACODE can achieve the best performances in terms of response time, ground resolution, and fuel consumption, respectively.

“…Somma et al (2019) use the following equation to depict the total population of objects N T at every discrete time t k in a specific altitude shell h: Where the subscripts AP, IP, RB, MR, CO and EX refer to the objects of the following categories respectively: active payloads, inactive payloads, rocket bodies, mission related objects, collision and explosion. A report by ESA provides an overview of the actual numbers of objects, categorised by absolute number, mass and area in geocentric orbit by object class, but also makes a clear disclaimer that their data is limited to: catalogued and asserted objects, and hence at any given epoch limited to the capability of the space surveillance system in use at the time.…”

Purpose In light of the discussions on outer space property management, this conceptual review paper aims to discuss and evaluate if, when and under which conditions certain land management and property right frameworks can apply to allocate and/or restrict property rights in outer space. Design/methodology/approach This paper applies a pragmatic review approach which seeks to better understand if and how the basic tenets of the land management frameworks could better shape and revise the challenges in outer space regulations. Findings Despite the fact that regulatory guidelines on outer space rights are existing, the analysis shows that these lack a number of practical tools and measures aiming at intervening if stakeholders do not follow the rules. With the use of land management frameworks, it is possible to derive policy options for making the outer space management more practical and action-oriented, in particular for the removal of space debris. These include amongst others more attention for formulating global public restrictions in outer space, incorporating regulatory guidelines for accessing open space regimes, addressing responsiveness and robustness in adherence and compliance to regulations Research limitations/implications Given the conceptual and discursive character of the paper, there are no specific empirical data, yet several recommendations for further research include expanding the boundary work between the land management and regulatory outer space domain. Practical implications The insights derived from land management and real estate related property theories could potentially provide new starting points for (re)formulating the regulatory framework for outer space property discourses. Social implications Interpreting the outer space regulations from known and practiced land management perspective helps to bridge the policy–society knowledge and necessity gap on outer space activities. Originality/value The specific land management perspective and discursive analysis on outer space debris provide new options for devising and extending regulatory guidelines for assigning responsibilities on outer space debris and debris rights, restrictions and responsibilities.
