This year, the General Assembly of the European Geosciences Union (EGU) featured a session on "Atmospheric impacts of rocket launches and artificial object re-entries: knowns, unknowns, and research priorities" for the first time.

It became clear how quickly the state of knowledge is expanding, for example in measuring and researching previously unknown processes of metals and aerosols, which did not exist in the atmosphere before the satellites. The issue of sustainability was also addressed. The study published last year entitled "Space sustainability through atmosphere pollution? De-orbiting, atmosphere-blindness and planetary environmental injustice" by researchers from the Leibniz Research Network “Earth & Societies” fitted very well into the session.
Just like the entire session, the study was well received not only by scientific colleagues, but also by the attending media. For example, the talks and poster presentations were filmed for a documentary on the topic of the session, which is scheduled for release in 2026.
