Climate change is threatening the sustainability of low Earth orbit, with new research from MIT revealing that shrinking atmospheric layers could significantly reduce the number of satellites able to operate safely by the end of the century.
Climate change is altering the environment of near-Earth space in ways that could significantly reduce the number of satellites able to safely operate in low Earth orbit by the century's end, according to a new study by the Massachusetts Institute of Technology (MIT), as reported by Anadolu Agency.
Published in Nature Sustainability on Monday, the research reveals that greenhouse gas emissions are causing the upper atmosphere, particularly the thermosphere, to shrink. This is the region where the International Space Station and most satellites orbit.
As the thermosphere contracts, the thinning air reduces the natural drag that typically slows down old satellites and space debris, causing them to re-enter the atmosphere and burn up. With less drag, defunct satellites and space junk will remain in orbit for much longer, increasing collision risks and overcrowding in low Earth orbit.
Researchers project that by 2100, the capacity of key orbital regions could decrease by 50%-66% if emissions continue to rise. The study highlights the urgent need for emission reductions and careful management of satellite launches.

'Superman' continued to dominate the summer box office, pulling in another $57.25 million in its second weekend, as theatres welcome a wave of blockbuster competition following a challenging few years for the film industry.
European forests are absorbing significantly less carbon dioxide than a decade ago, putting the European Union’s ambitious climate goals in jeopardy, scientists from the EU’s Joint Research Centre (JRC) warned on Wednesday.
The Environmental Protection Agency has moved to erase the foundation of America’s climate regulations. On Tuesday, it unveiled a proposal to rescind the “endangerment finding,” the legal opinion that lets it curb greenhouse gas emissions.
They seem distant and frozen in time, but glaciers are melting fast, and the ripple effects are reaching every corner of the world. From rising seas to disrupted weather and water shortages, their disappearance is reshaping our shared future.
The United Nation’s climate chief says a delay in choosing the host for next year’s COP31 summit is causing problems. It's after Australia and Türkiye submitted bids in 2022 to host the high-profile conference in 2026. Sydney said it's received the most votes.
