ISS De-Orbit Contract
In a contract worth as much as $843 million, NASA announced today SpaceX has been selected to develop a vehicle that will de-orbit the International Space Station in 2030.

I am posting this as it seems very much related to my Previous post to an article on Potential Ozone Depletion From Satellite Demise During Atmospheric Reentry in the Era of Mega-Constellations
It would be interesting to find how, how much Aluminium (if any) is contained within the ISS and how much of that will end up being subject to Oxidation given the evidence from the research in the depletion of the Ozone layer. This, I would guess, is in addition to any other satellites that also fall to Earth and burn up in the Atmosphere.

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.

There is a Fediverse discussion here that is quite interesting, I have also started a Science Forums discussion

Understanding the Atmospheric Effects of Spacecraft Re-entry
This was posted to the Fediverse. The original post from COSPAR, The Committee on Space Research (COSPAR): can be found here
This is an upcoming workshop looking at the environmental impact of spacecraft reentry in to the Earths Atmosphere.
This workshop will address the impact of spacecraft re-entry on the atmosphere. The aim is to bring together atmospheric chemists and physicists, material experts, the space industry, and international space research related organizations to highlight the gaps in our understanding of the modelling and how we can improve testing to obtain relevant data and suggest appropriate mitigation and regulatory measures.
This sounds like a fascinating area of research and discussion, as any exploration of space needs to take into account any environmental impacts.

Workshop information
It will be interesting to learn about the findings and conclusions from this, as it will open up further discussion on the topic(s) raised.
