When part of a SpaceX rocket re-entered Earth's atmosphere exactly a year ago, it created a spectacuglar fireball that streaked across Europe's skies, delighting stargazers and sending a team of ...

A plume of upper-atmospheric lithium pollution observed in February 2025 has been attributed to the re-entry of a specific rocket stage. The results, published in Communications Earth & Environment, ...

Atmospheric pollutants such as nitrogen oxides, ozone, sulphur dioxide and particulate matter exert profound influences on plant physiology and development. These compounds, primarily originating from ...

A SpaceX rocket that burned up after re-entering the atmosphere unleashed a plume of vaporised metals over Europe, a type of pollution that is expected to increase as spacecraft and satellites ...

Rainfall history is just as critical to predicting air pollution as where the air came from, a team led by University of Michigan Engineering researchers, in collaboration with scientists at the ...

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 ...

Atmospheric transport and source characterisation of air pollutants address how airborne substances move through the atmosphere and how their origins and pathways are identified. Pollutants such as ...

A drop in pollution during the covid lockdowns changed the chemistry of the atmosphere, driving a surge in methane levels that has concerning implications for future global warming. Methane lasts only ...

A new study of Earth's upper atmosphere has discovered spikes in lithium ion levels following the return of a Falcon 9 rocket upper stage, which broke up on reentry. With SpaceX planning to rapidly ...

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 ...
