Climate change increases Earth's space junk problem significantly

A new study from MIT reveals that rising greenhouse gas levels are thinning Earth's upper atmosphere, reducing its ability to pull space junk from orbit. This change could lead to a significant increase in space debris. The research indicates that by the end of the century, some orbital regions may safely support 66% fewer satellites due to the growing amount of space junk. This poses risks for satellite operations, especially with the rise of large satellite constellations. The study highlights the urgent need to manage greenhouse gas emissions to prevent overcrowding in space. Researchers warn that without action, the risk of collisions and debris could escalate, complicating satellite operations.
