Space & the Orbital Economy
The infrastructure layer above the atmosphere. Who controls it, what it costs, and why it matters for everything from broadband to nuclear deterrence.

(UCS/ESA; more than half are Starlink constellation satellites)
A note on framing. Space is covered unevenly. In popular media, the focus is on billionaire launches and Mars ambitions. In defence circles, the focus is on anti-satellite weapons and orbital deterrence. In the developing world, the focus is on connectivity and Earth observation. This page tries to hold all three together: the commercial economics, the military dimension, and the infrastructure role that space increasingly plays in everyday life. Sources include the Satellite Industry Association (SIA), Bryce Tech, the Center for Strategic and International Studies (CSIS), the European Space Agency (ESA), and the UN Office for Outer Space Affairs (UNOOSA).
The launch cost revolution
The single most important change in the space economy over the past fifteen years is the collapse in launch costs. In the Space Shuttle era, putting one kilogram into low Earth orbit cost roughly $54,000 (2024 dollars). SpaceX's Falcon 9, with its reusable first stage, brought that figure below $3,000 per kilogram. Starship, if it achieves its design targets, aims for under $200. These are not incremental improvements. They represent a shift from space as a government-budget activity to space as a commercial infrastructure layer.
SpaceX's dominance in launch is striking. In 2024, SpaceX conducted more launches than all other providers worldwide combined, including state agencies. This concentration raises questions that echo across the rest of this site: what happens when critical infrastructure depends on a single private actor? The comparison to railroad monopolies in the 19th century is imperfect but instructive. Other launch providers - United Launch Alliance (Boeing/Lockheed Martin joint venture), Arianespace (European), CNSA (Chinese state), ISRO (Indian state), Rocket Lab (US/New Zealand) - exist but operate at significantly lower cadence.
Satellite constellations and connectivity
The most visible consequence of cheap launch is the mega-constellation. SpaceX's Starlink, with over 6,000 satellites in low Earth orbit as of early 2026, provides broadband internet to areas where terrestrial infrastructure is absent or inadequate. Amazon's Project Kuiper, the EU's IRIS², and China's Guowang constellation are in various stages of deployment. The commercial model - subscription-based global broadband - is significant, but the geopolitical implications may be larger.
Starlink's role in the Ukraine conflict demonstrated that commercial satellite infrastructure is now a strategic asset. Ukrainian forces used Starlink terminals for battlefield communication when ground infrastructure was destroyed. This made a private company's service decisions - whether to enable or restrict coverage in specific areas - a factor in an active military conflict, a situation without clear precedent. China's military analysts have explicitly identified the need to develop capabilities to disable or disrupt satellite constellations in wartime.
For the developing world, the connectivity promise is more straightforward. Remote areas of Sub-Saharan Africa, Southeast Asia, and Latin America that may never receive fibre-optic or cellular infrastructure can access broadband through satellite. Whether this becomes a genuine development accelerator or creates new dependencies (on foreign providers, on subscription pricing, on orbital capacity allocated by a few governments) is an open question that connects directly to the broader infrastructure and power themes elsewhere on this site.
Militarization of orbit
Space has been militarily relevant since the beginning - early satellites were reconnaissance platforms, and nuclear-armed ballistic missiles transit through space. What has changed is the development of dedicated anti-satellite (ASAT) weapons and the creation of military space commands. The United States established Space Command in 2019. China restructured its military space assets under the PLA Strategic Support Force (now part of the Information Support Force). Russia, India, France, and Japan all have dedicated military space organisations.
ASAT demonstrations - destructive tests where a country destroys one of its own satellites to prove capability - have been conducted by the US (2008), China (2007), India (2019), and Russia (2021). The Russian test generated over 1,500 trackable debris fragments in orbits used by the International Space Station, prompting widespread condemnation. The debris problem illustrates a structural tension: the military incentive to develop ASAT capability directly conflicts with the commercial and civilian interest in keeping orbits usable.
The Outer Space Treaty (1967) prohibits weapons of mass destruction in space and the militarisation of celestial bodies, but it does not prohibit conventional weapons in orbit or anti-satellite systems. Efforts to negotiate updated space governance frameworks have stalled, primarily over disagreements between the US, China, and Russia on verification and dual-use technology definitions. Space governance is, in practice, where arms control was in the early 1960s - everyone agrees norms are needed, but the major powers disagree about what those norms should be.
Space debris
There are roughly 36,000 objects larger than 10 centimetres in Earth orbit tracked by the US Space Surveillance Network. Millions of smaller fragments - paint flecks, rocket body fragments, collision debris - are too small to track but travel at velocities where a centimetre-sized object carries the kinetic energy of a hand grenade. The concern is a cascade effect described by NASA scientist Donald Kessler in 1978: above a certain density threshold, collisions generate debris faster than atmospheric drag removes it, creating a self-sustaining chain reaction that could render entire orbital bands unusable.
Whether the Kessler syndrome is an imminent risk or a distant theoretical concern is debated. The current debris environment is manageable with collision avoidance manoeuvres, but the addition of tens of thousands of mega-constellation satellites in low Earth orbit changes the math. Active debris removal (ADR) concepts - nets, harpoons, robotic arms, lasers - exist as demonstrations but not as operational systems. The economic incentive problem is real: debris removal is a public good, and no single actor has sufficient incentive to pay for it.
Earth observation and resource sensing
The less glamorous but arguably more consequential dimension of the space economy is Earth observation. Satellite imagery and sensing data now underpin agriculture (crop monitoring, yield prediction), climate science (ice sheet measurement, sea level tracking, methane detection), disaster response (flood mapping, wildfire tracking), and financial intelligence (counting cars in retail parking lots as an economic indicator). Companies like Planet Labs operate fleets of small satellites that image the entire Earth's surface daily.
Asteroid mining and in-space resource utilisation remain largely aspirational. The technical capability to extract minerals from asteroids or lunar regolith is decades away from commercial viability, though water ice at the lunar poles (confirmed by multiple missions) could serve as propellant for deep-space missions, potentially changing the economics of space operations. Japan's Hayabusa2 and NASA's OSIRIS-REx missions successfully returned asteroid samples, demonstrating the science but not the economics.
The new space race: who is building what
The term "space race" is often used loosely, but the competitive dynamics are real. China has built and operates its own space station (Tiangong), has landed rovers on the far side of the Moon and on Mars, and is developing reusable launch vehicles. India's ISRO has demonstrated cost-effective missions (Chandrayaan-3's Moon landing in 2023 cost roughly $75 million, a fraction of comparable Western missions) and is building its own crew-capable vehicle (Gaganyaan). The UAE has placed a probe in Mars orbit. Japan, South Korea, and Israel all have active space programmes.
The Artemis programme (US-led, with ESA, JAXA, and CSA participation) and China's ILRS (International Lunar Research Station, with Russian and other partnerships) represent competing frameworks for lunar development. The question of who establishes norms, property rights, and governance structures on the Moon and in cislunar space is not abstract - it has direct implications for resource access, military positioning, and the institutional architecture of space governance for the rest of this century.
Where analysts disagree
How militarily significant is space? Some defence analysts argue that space-based assets (GPS, reconnaissance, communications) are now so critical to modern military operations that disrupting them would be a decisive act of war. Others argue that redundancy, hardening, and proliferation (thousands of small satellites rather than a few large ones) make space systems more resilient than the vulnerability narrative suggests.
Is Kessler syndrome imminent? Debris modelling is inherently uncertain. Pessimistic models suggest certain orbital bands could become unusable within decades without active remediation. Optimistic models argue that atmospheric drag in low Earth orbit provides a natural cleaning mechanism that limits cascading.
Does commercial space benefit or concentrate power? The techno-optimist view is that falling launch costs democratise access to space, enabling small countries and startups to participate. The structural-power view is that a few companies and countries control the launch infrastructure, the orbital slots, and the frequency allocations, reproducing terrestrial concentration patterns in a new domain.
Space is no longer a separate domain reserved for superpowers and science fiction. It is an infrastructure layer - for communication, navigation, surveillance, and increasingly for military operations - that most people depend on daily without noticing. Who controls that layer, who sets the rules, and what happens when the rules are contested are questions that will shape the rest of this century.
