Encore: The atmospheric impacts of satellite re-entry.

April 26, 2026 • 26 mins
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. This process, known as atmospheric ablation, is still poorly understood, but early evidence suggests metal content in the atmosphere is rising. To address these uncertainties, the UK Space Ag...
