The New Era of Satellite Launches
Launching the first commercial satellites, like Telstar-1 and Telstar-2, once cost nearly $400,000 per kilogram in the 1960s. Today, thanks to innovations like SpaceX’s Falcon 9 program, this cost has plummeted to about $6,500 per kilogram, according to data from Kfund. This significant reduction in launch costs has opened the door for a vast range of organizations and companies, allowing them to contribute to the growing number of satellites in orbit. As a result, Earth’s orbit is becoming saturated at an unprecedented rate.
Filling the Sky: A Democratization of Space
The realm of space, once dominated by governments and large corporations, is now accessible to startups with modest budgets. For instance, FOSSA Systems, a Spanish company, has successfully deployed over 20 satellites with less than €10 million in funding. Between 2021 and 2024, Spain alone has seen its number of space objects launched increase more than threefold, from 21 to 69 payloads. Globally, the speed of deploying entire satellite constellations has drastically reduced—from decades to just a handful of months.
Driving Factors Behind Satellite Launch Cost Reduction
The drop in satellite launch costs stems from several converging factors. Key among them is the advancement in reusable rocket technology, pioneered by SpaceX. Further, the standardization from custom-built, large satellites to modular microsatellites has made operations more efficient. Economies of scale also play a vital role, allowing operators to maximize their resources and minimize costs.
The Complications of More Satellites
This surge in satellite launches has introduced a complex set of challenges. The lowered barriers to entry increase the prospect of launching satellites without centralized coordination, thereby heightening the risks of collisions. As low Earth orbit becomes increasingly crowded, the consequences of this overcrowding—such as the exponential growth of space debris—are becoming alarming. Each collision not only generates debris but poses a risk for future launches and operational satellites. Moreover, frequency interference in communications and escalating militarization in orbit are additional issues that complicate this new landscape.
Outdated Legal Frameworks
The current international treaties governing outer space were designed during the Cold War era, when only two powers had the capacity for orbital access. Today, the landscape has shifted dramatically with hundreds of private and state operators. These outdated legal frameworks are proving insufficient for managing the limitations on satellite launches, satellite placements, and post-mission orbital cleanup. This has led to what can be termed an “orbital tragedy of the commons,” where the benefits of cheap access are shared by many, while the costs are diffuse and poorly managed.
The Fragmented Governance of Space Infrastructure
As Silviu Pirvu, the Chairman and CTO of Optimal Cities, notes, “the world is continually changing, in some places faster than before.” The growing reliance on space infrastructure for real-time decision-making underscores the need for a coordinated governance system. In response, initiatives like Europe’s IRIS² aim to build sovereignty and reduce dependency on non-European suppliers, although regulatory fragmentation still prevails.
Long-Term Risks: Kessler Syndrome and Its Implications
The scientific community has long raised alarms about the potential for Kessler syndrome—a scenario where cascading collisions render specific orbits unusable for generations. Current projections by the European Space Agency estimate that more than 36,000 objects larger than 10 centimeters are already in orbit, with a majority classified as space debris. Each year without effective regulation further exacerbates the risk of reaching this critical point.
Regulating a Global Commons
With such pressing questions at hand, the challenge remains: how do we regulate a global common good in space amidst conflicting commercial and strategic incentives? While various monitoring systems, such as the Space Situational Awareness (SSA) program from ESA, exist, they fail to address the core issue of establishing concrete limits. Without effective governance, the future of space infrastructure becomes increasingly perilous.
