There are now more than 11,000 active satellites in Earth orbit, and more than 9,000 of them belong to a single private company. Astronomers expect that roughly ten percent of the images produced by the Vera C. Rubin Observatory — a telescope designed for once-in-a-generation surveys of the southern sky — will contain satellite streaks once the planned megaconstellations are in place. An analysis in 2025 argued that a sufficiently large solar storm, by temporarily disabling satellite-maneuver capabilities, could set off a cascade of collisions in low Earth orbit that would render parts of it unusable. This is what orbital commons governance looks like at the moment: largely absent, retroactively constructed, and on the clock.
When the book was published, private launch cadence was modest, Starlink did not exist, and low Earth orbit was a relatively uncongested commons. The shift since has been driven by four overlapping developments.
Private launch capacity. SpaceX’s Falcon 9 reuse programme, followed by the Starship development cycle, has collapsed the cost-per-kilogram to orbit by roughly an order of magnitude. This is the engineering achievement that everything else on this page depends on. It has democratised access to space for states, companies, and universities that previously could not afford it. It has also created the conditions for a single commercial operator to dominate low Earth orbit.
Megaconstellations. Starlink, OneWeb (now Eutelsat OneWeb), Amazon Kuiper, and Chinese competitors have proposed constellations totaling tens of thousands of satellites. As of late 2025, Starlink alone had more than 9,300 operational satellites — a figure that exceeds the total number of operational satellites ever launched by all other operators combined before 2019. The capability this has delivered (low-latency broadband to rural and conflict areas, most visibly in Ukraine) is real and consequential. The externalities are still being mapped.
Astronomical impact. The Vera Rubin Observatory — formally the Large Synoptic Survey Telescope — is the most affected ground-based optical observatory. Rubin has incorporated mitigation into its observation scheduling and image-processing pipeline, but the mitigation is a defensive response, not a solution. Radio astronomy is under separate pressure from satellite downlink interference; the Square Kilometre Array and its precursors have documented specific bands in which Starlink transmissions overlap radio-astronomy observation windows.
Kessler cascades as a live concern. The Kessler syndrome — a self-sustaining cascade of collisions in low Earth orbit — was proposed as a scenario in 1978. It has moved from scenario to active scenario planning. Avoidance maneuvers between operational satellites and debris are now frequent; a significant fraction of Starlink maneuvers are to avoid other satellites, including other Starlinks. The question is no longer whether Kessler dynamics can begin; the question is whether the existing conflict-of-interest among operators and the absence of a binding international debris regime can prevent them from beginning.
Anti-satellite tests. Russia’s 2021 destructive ASAT test, following earlier US (1985, 2008), Chinese (2007), and Indian (2019) tests, added orbital debris at altitudes where it will persist for decades. No international regime prevents further tests, and the incentives to retain ASAT capability are strong.
The governance void is the central issue. The 1967 Outer Space Treaty establishes space as a commons “free for exploration and use by all States without discrimination” and prohibits weapons of mass destruction in orbit. It does not regulate commercial constellations, orbital debris, or private resource extraction. The 1979 Moon Agreement addresses lunar resources but was signed by few nations — none of them spacefaring powers. The de facto regulator is the US Federal Communications Commission’s licensing process, which was not designed for planetary-scale coordination and does not bind non-US operators. Space governance is currently an emergent property of unilateral state action, commercial self-interest, and aspirational diplomacy.
The Power, Privilege, and Access dimension is acute. Low Earth orbit is a finite resource that is being enclosed by first-movers. Once a constellation occupies a set of orbital shells, later entrants must operate in less favourable regions, accept higher collision risk, or wait for the incumbent to deorbit generationally. A private actor has, in effect, claimed a significant fraction of the most useful orbits — not through any recognised international mechanism, but by getting there first with licensing cover from a sympathetic regulator.
The Permissionless Innovation pattern applies at planetary scale. No public deliberation preceded the decision that low Earth orbit would be populated with tens of thousands of commercial satellites by a single operator. The deliberation is happening after, in response to externalities that the deployment has produced.
The Risk Innovation framework catches what conventional risk assessment misses. The night sky has been a cultural commons for all of human history; what is lost when it ceases to be is not captured by any insurance policy or regulatory impact assessment. So is the scientific capability represented by observatories like Rubin. Both are threats to belonging and cultural inheritance in the book’s expanded risk vocabulary.
What the book directly addresses. Contact is the only space-adjacent chapter, and its subject is SETI, not industrialisation. The book’s treatment of power, privilege, permissionless innovation, corporate responsibility, and the Risk Innovation framework apply directly. Governing Across Borders applies almost literally — there are no borders in orbit, and the governance challenge is exactly that.
What the frameworks suggest when extrapolated. The book’s general argument that capability precedes governance is unusually clean here. The specific question of how to govern orbital commons is one the book’s frameworks point at without answering. The conceptual toolkit from Complexity and Unintended Consequences is directly applicable to Kessler-cascade dynamics: small triggers, positive feedback, a stable state that is very different from the pre-trigger one.
Where the frameworks reach their limits. The book does not address astronomy-as-commons, cultural heritage of the night sky, or the specific diplomacy of commons governance in international relations. These are extensions the book invites but does not complete.
Films outside the book’s twelve: Gravity (2013, Alfonso Cuarón) makes debris viscerally legible in a way most policy treatments do not. Moon (2009, Duncan Jones) addresses corporate space labor with a precision that will only become more relevant. Ad Astra (2019, James Gray) treats private space infrastructure and its human costs in a register the book’s frameworks engage well.
