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 could undermine 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 satellites will 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.
Tell the FCC: ⭐️Satellite mega-constellations need #environmental #review⭐️
We should look before we leap.
The number of satellites in mega-constellations that power satellite internet has ♦️increased by 127 times in five years♦️, in large part because of SpaceX.
At peak deployment of these disposable satellites, 29 tons of metal will re-enter our atmosphere per day.
That’s almost like a Jeep Cherokee falling from space every hour.

I think the point here is that this is a problem, but the post really fails to connect the dots. Might be helpful to mention why it should be concerning that aluminum oxide is entering earths atmosphere. Since its a solid and fairly naturally occuring I think most people would assume its a non issue without more info.
Prompt: What harm is done to the upper atmosphere by massive amounts of low orbit satellites burning up on atmospheric reentry? What harm is caused particularly by aluminum oxide?
»Aluminum oxides, produced during the burning of satellites, are known to react destructively with chlorine compounds in the atmosphere, leading to ozone depletion. Research indicates that these oxides can persist in the atmosphere for decades, exacerbating the degradation of the ozone layer…«
