Cracks in the International Space Station are causing air leaks – how much longer can it remain habitable?

In June 2026, NASA had to temporarily halt operations on the International Space Station due to a serious air leak in its Russian segment, prompting astronauts to seek shelter in a docked spacecraft. While the situation was resolved without immediate danger, this incident highlights the aging infrastructure of the ISS and raises concerns about its long-term habitability. As the station continues to show signs of wear and tear, the question looms over how much longer it can safely support human life and scientific research, underscoring the urgent need for future space station upgrades or alternatives.
