“When a #satellite demises, it's still there in the #atmosphere in the form of small particles of #aluminum, and we don’t know what these particles actually do in the atmosphere.” Most of this destruction happens at altitudes between 60 and 80 kilometers—too high for balloons 🎈 and planes to reach, but too low for satellites to sample.

And here you can read all about the "Zero Debris Approach" and the rules for that, that are binding for all missions and satellite constructions : https://www.esa.int/Space_Safety/Space_Debris/Mitigating_space_debris_generation

For loads and loads of information on space debris, you should take a look at the dedicated page at https://www.esa.int/Space_Safety/Space_Debris from the European Space Agency.

While Elon Musk dumps a used car in space, an upper stage on the moon and burns hundreds of throw-away satellites in our atmosphere, Europe has strict rules on minimal impact of space debris and is researching how to do a Space Cowboys like cleanup system.

#Reentry debris has fallen on both private and public property around the world multiple times since 2021. Trunk debris from the Crew 7 mission to the #ISS has landed in #NorthCarolina, and fragments from the Crew 1 mission landed in #NewSouthWales, #Australia. Similarly, debris from the Axiom 3 mission landed in #Saskatchewan, #Canada.
In 2025, 4,500 objects launched, meaning 20% of all objects launched into space since the 1950s were launched last year. https://theconversation.com/falling-space-debris-poses-an-escalating-risk-as-spacecraft-get-stronger-and-more-heat-resistant-279077

Video of the plume from the SpaceX upper stage crash on the moon posted by Jose Maria Madiedo at the Astrophysics Institute of Andalusia (IAA-CSIC).
Probably taken at the Sierra Nevada Observatory at Loma de Dilar (2,896 m altitude) in the Sierra Nevada mountain range, in the province of Granada, Spain.

📆 July 5, 1969 Japanese diplomats revealed that a small Japanese freighter 🚢 was hit 💥 by wreckage from a Soviet spacecraft while cruising near the coast of Siberia. The Japanese Government 🇯🇵 apparently had decided not to make a public disclosure of its finding because it did not want to provoke an incident with #Moscow https://www.nytimes.com/1969/07/05/archives/soviet-space-debris-hits-japanese-ship-injuring-5.html

These incidents are becoming so common that the #Australian 🇦🇺 #SpaceAgency has put together a trio of steps to take if suspected space debris is discovered.
"Very often they will be made of something like titanium which is really good at surviving. Just don't let them randomly reenter. Bring them down via controlled reentry and then if they are survivable it doesn't matter because you dump them somewhere where there aren't any people" 🤕 https://www.space.com/space-exploration/launches-spacecraft/metal-spheres-found-in-australia-show-how-little-we-still-know-about-falling-space-debris-experts-say

🇵🇱 February 2025 "The important thing is that no-one was harmed," police spokesperson Andrzej Borowiak said.

2025 the #US #SpaceForce issued alerts for ~820 objects entering the Earth’s atmosphere, compared to 110 a decade ago. Huge objects weighing a metric #tonne or more arrive about once a week.
> 300 rockets launched last year, ~four times as many 📈 as a decade ago. Companies should be compelled to use materials that will fully disintegrate. No such #SpaceRegulation exists.

Is that all? Only ~1 Ton per week?
Last year, the U.S. Space Force issued alerts for nearly 820 objects entering the Earth’s atmosphere.
“Re-entries happen each and every day,” "Huge objects weighing a metric ton or more arrive about once a week" according the space collision experts.
While much of the debris incinerates in the atmosphere or splashes into the Pacific, but when it does not - it can land anywhere and on one can predict where.
SpaceX indicates ~5% of the mass of some of its satellites may not disintegrate when they "de-orbit". https://www.nytimes.com/2026/07/31/world/asia/space-debris-falling-crashing-earth-risk.html?unlocked_article_code=1.11A.WhlN.uAdqod1FWRBC

That article by Mark Hurst is nearly two years old now. Change will probably only start to come when debris comes down in a major metropolitan area.

“Vaporizing a car’s worth of aluminum, other metals, and chemicals in the upper atmosphere, every hour, indefinitely? Not good.”
