In a bold push towards the cosmos, tech giants Elon Musk and Jeff Bezos are championing the launch of orbital data centres designed to revolutionise the digital landscape. However, a coalition of environmental experts and advocacy groups has raised alarm bells, arguing that these ambitious plans could unleash devastating levels of pollution, altering the Earth’s atmosphere and putting our planet’s health at unprecedented risk. A recent petition has called for a thorough review of these initiatives, demanding that the Federal Communications Commission (FCC) pause new licensing until the environmental impacts are fully assessed.
A Call to Action
The petition, spearheaded by the Public Employees for Environmental Responsibility (Peer), Earthjustice, and DarkSky International, highlights the pressing need for scrutiny of the millions of proposed “orbital data centres”. These ambitious projects, which hinge on launching thousands of satellites, are currently seeking approval from the FCC. Experts warn that pollutants emitted by rockets, including black soot and rare metals, are accumulating in the stratosphere at alarming rates, potentially jeopardising the ozone layer and exacerbating the ongoing climate crisis.
“The pollution from these spacecraft could harm the ozone layer, leading to increased ultraviolet radiation exposure,” warns Steve Volz, former head of NOAA’s satellite office. He emphasises that the potential consequences of this pollution could be dire, raising serious concerns about the long-term health of our atmosphere.
The Alarming Growth of Satellites
Since 2015, the number of satellites orbiting our planet has skyrocketed from around 1,400 to approximately 15,000, with projections suggesting that figure could reach a staggering 100,000 within the next decade. The majority of this growth is attributed to megaconstellations like SpaceX’s Starlink and Amazon’s planned network, which are designed to provide global internet coverage.
But with this rapid expansion comes significant environmental challenges. Each launch emits a cocktail of harmful gases, including nitrogen oxides and carbon monoxide. When decommissioned, satellites release additional pollutants, introducing metals into the stratosphere—an already fragile ecosystem crucial for climate regulation.
Researchers recently discovered alarming levels of metals within sulfuric acid aerosols in the stratosphere, a finding that underscores the urgent need for further investigation into the interactions between these pollutants and the planet’s natural systems.
A New Era of Light Pollution
As tech companies turn their sights to the night sky, the potential for light pollution becomes a grave concern. Ruskin Hartley, executive director of DarkSky International, warns that these developments could irreversibly alter the nocturnal landscape. “These projects could permanently change the night sky as we know it,” he states, calling for the FCC to uphold its responsibility to protect natural dark skies.
Moreover, the environmental toll extends beyond mere aesthetics. The impact on ecosystems—particularly those reliant on darkness, such as fireflies and other nocturnal species—could be catastrophic. The cumulative effects of light pollution are already evident, with several species facing decline due to habitat disruptions.
Legal and Environmental Implications
The petition calls attention to the necessity for the FCC to adhere to the National Environmental Policy Act (NEPA), which mandates a comprehensive assessment of potential environmental impacts before approving new projects. The groups argue that the FCC must determine whether the proposed satellite systems serve the public interest and convenience, and whether their environmental risks have been adequately mitigated.
Among those seeking permits is Cowboy Space Corporation, founded by a billionaire co-CEO of Robinhood, which aims to establish a 20,000-satellite network by 2028. The petition critiques the company’s environmental mitigation plans, stating that they lack substantial detail and fail to address the broader implications of such a massive deployment.
Why it Matters
The push for orbital data centres is not merely an innovative leap into the future; it represents a critical juncture in the intersection of technology and environmental stewardship. If allowed to proceed without rigorous oversight, these initiatives could set a dangerous precedent, prioritising corporate ambitions over planetary health. As we continue to explore the possibilities of space, it is imperative that we also safeguard our earthly environment. The outcome of this petition could shape the future of space exploration and its impact on our planet for generations to come.
