<p><strong>Potential Ozone Depletion From Satellite Demise During Atmospheric Reentry in the Era of Mega-Constellations</strong></p>

<p>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.</p>

<p>Give the number of Satellites in orbit and the importance of the Already fragile Ozone layer, this is not good news.</p>

<p>You can read the <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024GL109280" rel="nofollow">research here</a></p>

<p>There is a Fediverse <a href="https://qoto.org/web/statuses/112673715671774536" rel="nofollow">discussion here</a> that is quite interesting,   I have also started a <a href="https://www.scienceforums.net/topic/134226-potential-ozone-depletion-from-satellite-demise-during-atmospheric-reentry/" rel="nofollow">Science Forums discussion</a></p>
