Scientists Warn Satellite Launches Could Drive 42% of Space Pollution's Climate Impact by 2030

A new study says satellite launches are becoming a major climate risk, with black carbon from rockets projected to account for 42% of the space sector's pollution-driven climate impact by the end of the decade.
Black carbon released into the upper atmosphere lingers far longer than ground-level soot, giving it about 540 times the environmental impact, according to the researchers.
The warning comes as companies including SpaceX rapidly expand satellite megaconstellations, pushing launch rates higher than the 2020-2022 data used in the study and potentially making the estimates too low.
Researchers said the pollution may block some sunlight like geoengineering, but called it an unregulated experiment with hard-to-predict effects, adding that regulation remains limited while impacts are still relatively small.
As thousands of satellites burn up daily, are we creating a permanent metal shell of pollution around Earth?
With SpaceX planning a million satellites, is Earth's orbit on the verge of unregulated chaos?
Are private companies conducting an unregulated geoengineering experiment in our atmosphere?
The Unregulated Space Race: How Satellite Megaconstellations and Rocket Launches Threaten Earth's Climate and Ozone Layer
Overview
The current era is witnessing an unprecedented surge in space activity, fueled by booming investment and the rise of space tourism. This rapid expansion is pushing the boundaries of human exploration and technology, but it also casts a growing climate shadow over Earth. Scientists are now revealing the significant global carbon footprint of space exploration, as rocket launches and re-entries contribute substantially to atmospheric pollution and climate change. The environmental consequences of this acceleration are becoming increasingly clear, highlighting the urgent need to address the impact of space activities on our planet’s atmosphere and climate.
