Satellite megaconstellations may be creating an unexpected climate tradeoff

A new paper highlighted by Universe Today argues that the fast growth of satellite megaconstellations could amplify the climate impact of rocket launches, especially through long-lived soot in the stratosphere.

Key Takeaways

Researchers warn that megaconstellation launches may claim a growing share of launch-related climate impact.
The key concern is soot that can remain in the stratosphere for years.
