"The demise of just one Gen1 Starlink satellite produces about 30 kilograms (66 pounds) of aluminum oxide, a compound that eats away at the ozone layer. A new study finds these oxides have increased 8-fold between 2016 and 2022, and the recent surge is increasing the pollution even more." The atmosphere weighs 5.1 billion billion kilograms. In other words, each satellite adds 1/203,333,333.333 more to the stratosphere.The article would be more honest if it talked to the percentage increase overall rather than the increase in detection. This paper gives some pretty good estimates for the amount of this stuff entering the atmosphere: https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2024GL109280#:~:tex= t=3DUpon%20reaching%20an%20altitude%20of,reaching%20the%20stratospheric%20o= zone%20layer. But doesn=C2=B4t project the effect on the ozone layer (in a quick skim) ... The article does not include any reference to the amount of global warming added by aluminium oxide, but I originally imagined that it is comparable to freon as to its effects to within an order of magnitude. It is believed there are several million kilograms of Freon in the atmosphere today. But in researching this, it seems to believed here that alum oxide actually might reduce global warming, but contributes to alzheimers!!? https://www.bmj.com/content/377/bmj.o1150/rr-1 Now, since the quantities involved are so minute... coping... with either conclusion... from this brief foray from the article, into the science... is beyond my ken, and the study itself was definately worth reading, and they should probably fly test flights more often. https://spaceweather.com/archive.php?view=3D1&day=3D06&month=3D02&year=3D20= 25 PS meteoroid flux averages at 32.2 metric tons/day.
