Potential Ozone Depletion From Satellite Demise
Potential Ozone Depletion From Satellite Demise During Atmospheric Reentry in the Era of Mega-Constellations
Interesting paper that was published in Geophysical research letters looking at potential damage to the Ozone layer from Satellites re-entering the Earths atmosphere and burning up. The specific issue seems to be related to the Aluminium Oxidizing, and then this travels down to the Ozone layer and causes a chemical reaction.
Give the number of Satellites in orbit and the importance of the Already fragile Ozone layer, this is not good news.
You can read the research here
There is a Fediverse discussion here that is quite interesting, I have also started a Science Forums discussion
Update : 2/4/2025: To give an idea what is up in orbit, this graphic is an interactive representation of all the satellites that are up there.
Update June 29 – Satellite collisions cause a chain reaction
Update June 25 – Near-future rocket launches could slow ozone recovery
Update July 3rd – More re-entry stats
Update 3rd July Thousands of satellites are due to burn up in the atmosphere every year – damaging the ozone layer and changing the climate
