Please enjoy this encore while the team is out on vacation.


When satellites burn up upon re-entering Earth’s atmosphere, they release particles and gases, including metals like aluminium, which may affect atmospheric chemistry.

To address these uncertainties, the UK Space Agency commissioned three targeted studies to investigate the potential impacts of satellite re-entry. We spoke to Professor Minkawn Kim from the University of Southampton about his findings.
