Satellite launch pollution is rapidly accumulating in the upper atmosphere

The potent pollution from so-called megaconstellation satellite systems launched en masse into space since 2019 will account for nearly half (42%) of the total climate impact of space sector pollution by the end of the decade, finds a new study led by UCL researchers. As described in Earth's Future, the research team examined air pollution produced by the growing number of rocket launches, and the discarded rocket bodies and dead satellites falling back to Earth.
