Experts Petition FCC to Halt Licensing for Orbital Data Centers

Petition Challenges Orbital Data Center Expansion

Tech companies have proposed the launch of millions of data center satellites, a move they argue is necessary to scale artificial intelligence operations. Proponents, including Elon Musk, have described orbital data centers as an obviously the only way to scale, suggesting that moving infrastructure to space could eventually help re-zone Earth by shifting polluting industries off-world.

Atmospheric and Environmental Risks

The petition highlights significant concerns regarding the pollution generated by both the launch and decommissioning of these satellites. According to Theguardian, spacecraft release black soot, aluminum oxides, and rare metals into the stratosphere during launch and upon re-entry. Scientists fear this accumulation could potentially damage the ozone layer, alter the Earth’s temperature, and expose populations to increased ultraviolet radiation.

Beyond emissions, the physical infrastructure required to operate data centers in space presents unique engineering and environmental hurdles. Because space lacks air or water for cooling, orbital data centers would require massive ammonia-filled radiators to dissipate heat from AI chips. Lifting these large structures into orbit necessitates high-frequency rocket launches, each consuming over 1,000 tonnes of liquid methane and releasing approximately 80,000 tonnes of CO₂. Furthermore, standard spaceport deluge systems release roughly 2 million liters of water per launch to protect equipment from heat and toxic dust.

Impacts on Astronomy and the Night Sky

Astronomers and researchers warn that the sheer volume of proposed satellites—potentially exceeding one million units—could permanently alter the night sky. Simulations conducted by experts, including astronomer Samantha Lawler of the University of Regina, indicate that these satellites could outnumber stars and create a visible, luminous band of light circling the Earth.

This diffuse sky brightness threatens to hinder astronomical research by obscuring distant galaxies and reducing the efficiency of taxpayer-funded telescopes. According to The Times of India, even if individual satellites are faint, their collective presence creates a brighter backdrop that makes detecting faint signals from the early universe significantly more difficult. In addition to scientific disruption, advocates such as Ruskin Hartley of DarkSky International warn that the increase in light pollution contributes to insect die-offs and disrupts natural ecosystems that rely on darkness.

Orbital Congestion and Regulatory Status

The current orbital environment is already heavily congested, with the number of active satellites growing from approximately 1,400 in 2015 to 15,000 today. Experts caution that the addition of millions more, combined with the risk of Kessler Syndrome—a chain reaction of collisions creating uncontrollable space debris—could hinder human space activity for generations.

Operational risks also include “bit flipping,” where high-energy particles in space cause data errors in microchips. Because retrieving damaged hardware from orbit is not financially viable, satellites are typically de-orbited after five to 15 years, where they vaporize and release accumulated metals into the atmosphere.

While the FCC has begun reviewing permit applications for these networks, opponents argue that companies have failed to conduct sufficient inquiry into the environmental and scientific impacts of their technology. As of July 2026, the intense competition between major players like SpaceX and Blue Origin continues to drive the rapid development of these projects, even as the public and scientific communities demand a more cautious regulatory approach.
