Report: Low Earth Orbit (LEO) Satellite Systems Like Starlink Cause Environmental Harm Regulators Didn’t Prepare For

Last June scientists warned that low-Earth orbit (LEO) satellites constantly burning up in orbit could release chemicals that couldundermine the progress we've made repairing the ozone layer. Researchers at USC noted that at peak, 1,005 U.S. tons of aluminum will fall to Earth, releasing 397 U.S. tons of aluminum oxides per year to the atmosphere, an increase of 646% over natural levels.

Numerous companies, most notably Elon Musk's Starlink and Jeff Bezos' Blue Origin, are working on launching tens of thousands of small LEO satellites in the coming years. A new report by U.S. PIRG adds to concerns that these launches haven't been thought through environmentally, noting that the disposable nature of such satellites means 29 tons of satelliteswill re-enter our atmosphere every day at peak.

After years of delays, the FCC did recently release rules requiring that satellites be removed from orbit within five years to help minimize space junk." But the organization notes that very little if any thought was given by innovation-cowed regulators toward the environmental impact of so many smaller satellites constantly burning up in orbit:

We shouldn't rush into deploying an untested and under-researched technology into new environments without comprehensive review. Over just five years Starlink has launched more than 6,000 units and now make up more than 60% of all satellites. The new space race took off faster than governments were able to act."

The steady launches are also a notable pollution concern, the report notes, releasing soot in the atmosphere equivalent to 7 million diesel dump trucks circling the globe, each year." Space X has consistently played fast and loose with environmental regulations, with regulators even in lax Texas starting to give the company grief for releasing significant pollutants into nearby bodies of water.

These concerns are on top of additional complaints that the light pollution created by these LEO satellites are significantly harming astronomical research in a way that can never be fully mitigated. And again, the problems we're seeing now are predominately caused by Musk's Starlink. Bezos and other companies plan to launch hundreds of thousands of more satellites over time.

SpaceX's Starlink service can be a game changer for those completely out of range of broadband access. It's also proven useful during environmental emergencies and war. Getting several hundred megabits per second in the middle of nowhere is a decidedly good thing, assuming you can afford the $120 a month subscription cost and up front hardware costs.

But while Starlink is great for global battlefields, vacation homes, yachts, and RVs, it's not truly fixing the biggest problem in U.S. broadband right now: affordability. It lacks the capacity to really drive competition at the scale it's needed to drive down rates, and as its userbase grows it's inevitably going to require more and more heavy-handed network management tricks to ensure usability.

So while these LEO services are a helpful niche solution to fill in the gaps, they come with some fairly notable caveats, and it's generally more economically and environmentally sound to prioritize the deployment of fiber and then fill in the rest with 5G and fixed wireless. It's a major reason why the Biden FCC retracted a wasteful billion-dollar Trump handout to Starlink, something that made MAGA cry.
