WASHINGTON, July 7 — 5,500. That is the number of Starlink satellites SpaceX has already launched into low-Earth orbit. The company’s ultimate plan calls for 42,000.
The bottom line: a regulatory fight over how to dispose of that hardware is now underway, and it pits Elon Musk’s space empire against some of the country’s most established environmental groups. SpaceX, founded by Musk in 2002, dominates the satellite internet business.
Musk serves as CEO and Chief Engineer. The company’s Starlink constellation is the largest commercial satellite network in history. But with scale comes scrutiny.
The Federal Communications Commission, which regulates satellite licensing, is considering a rule change that would exempt satellite deorbitings from environmental review under the National Environmental Policy Act, or NEPA. That proposal has drawn formal opposition.
Two environmental organizations have filed comments against the exemption. The Natural Resources Defense Council, founded in 1970, and the Union of Concerned Scientists, founded in 1969, both argue that the FCC should not bypass NEPA review. Their position is straightforward: the planned disposal of thousands of satellites carries atmospheric consequences that merit federal study.
The science behind the debate
Dr. Joseph Wang, a researcher at the University of Southern California, has published studies on atmospheric impacts. The data is still accumulating, but the question is central to the FCC’s deliberations. When a satellite deorbits, it incinerates in the atmosphere.
The concern is that metals and other compounds from thousands of incinerated spacecraft could accumulate in the upper atmosphere in ways scientists do not yet fully understand. Astronomers have a separate but related complaint.
The International Astronomical Union established the Centre for the Protection of the Dark and Quiet Sky in 2022 specifically to document how satellite constellations interfere with ground-based observations. Starlink satellites are bright. They leave streaks across telescope images.
For professional astronomers, this is not a theoretical problem — it is a daily operational headache that degrades data. SpaceX’s deorbiting practices are at the center of the environmental debate.
The company has launched over 5,500 Starlink satellites to date. Many of those will eventually need to be brought down. The company’s expansion plan, if fully realized, would push the constellation to 42,000 satellites.
That figure — 42,000 — is the number that matters for long-term planning. It represents a scale of orbital infrastructure that has no precedent.
The regulatory landscape
FCC Chairwoman Jessica Rosenworcel, appointed in 2021, oversees the agency’s satellite licensing division. Her commission is weighing whether to exempt deorbitings from NEPA review. The environmental groups argue that such an exemption would set a dangerous precedent.
If the FCC allows SpaceX to dispose of thousands of satellites without environmental assessment, they contend, it effectively greenlights a large-scale atmospheric experiment with no oversight. The NRDC and UCS have both been involved in satellite and space policy before, but this particular fight is new in scale.
Previous debates focused on rocket launches and ground-based environmental impacts. The question now is atmospheric — what happens when the satellites come down. That shift in focus reflects the sheer number of objects involved.
Five thousand five hundred satellites burning up is one thing. Forty-two thousand is another.
What to watch next
The FCC has not yet ruled on the exemption request. The comments from the NRDC and UCS are now part of the public record. The agency will need to decide whether to proceed with the rule change, modify it, or abandon it.
That decision will set the regulatory framework for the entire commercial satellite industry, not just SpaceX. Dr. Wang’s research will likely feature in whatever environmental assessment follows.
The astronomical community will continue to press its case through the International Astronomical Union’s dark-sky center. And SpaceX will continue launching satellites — the company shows no signs of slowing its deployment pace. The figure that matters for investors, regulators, and scientists alike is 42,000.
That is the target. How the FCC handles the disposal of what is already in orbit will determine whether the path to that target is smooth or contested.
