Plans by companies including Elon Musk's SpaceX and Jeff Bezos' Blue Origin to establish data centers in orbit are facing scrutiny from scientists concerned about potential environmental ramifications. A coalition of experts, represented by Earthjustice, is urging the Federal Communications Commission (FCC) to conduct a comprehensive review of the ecological risks associated with these proposed space-based facilities.
Proponents of space data centers highlight advantages such as access to limitless solar power and reduced operating costs, as well as mitigating environmental impacts associated with ground-based data centers. The increasing demand for computing storage, driven in part by advancements in artificial intelligence, has fueled interest in these orbital solutions. Jeff Bezos has previously predicted the development of space data centers within the next 10 to 20 years, with Elon Musk confirming SpaceX's intention to pursue this endeavor.
However, critics argue that deploying millions of satellites for data centers could significantly alter Earth's atmosphere, disrupt wildlife, and permanently change the night sky. Tim Whitehouse, executive director of Public Employees for Environmental Responsibility, stated that launching numerous orbiting data centers without environmental review is "irresponsible" and "reckless," emphasizing the need to consider the potential for atmospheric degradation from pollution and debris, as well as harm to wildlife.
Recent petitions filed with the FCC highlight concerns regarding the known environmental impacts of satellite technology. Rocket launches and re-entries are associated with significant emissions and can contribute to ozone layer depletion. Jan Hasselman, senior attorney at Earthjustice, stressed that expanding the satellite presence in space has direct consequences for human lives and the planet's future. He asserted that regulatory agencies must operate within the law, which necessitates considering all risks and impacts of such proposals, with legal action a possibility if compliance is not met.
Beyond atmospheric concerns, scientists also point to the potential for light pollution from these orbital facilities to disrupt wildlife and alter natural night sky conditions. Ruskin Hartley, executive director of DarkSky International, warned that these projects could permanently change the night sky and urged the FCC to uphold its obligation to prevent unnecessary harm to dark skies and the environment.
