ISS Countdown: Can Private Space Stations Keep the U.S. in Orbit?

With the International Space Station aging and its retirement looming around 2030, the U.S. risks losing continuous human presence in low Earth orbit unless commercial space stations come online. NASA's plan hinges on late-2020s/early-2030s proposals and contracts, while a Senate bill seeks to extend ISS operations to 2032 to avoid a gap. Private firms like Vast and Axiom Space are racing to launch habitats (Haven-1, ISS-attached modules), but overall funding and NASA procurement delays complicate the timeline. China’s Tiangong and Russia’s potential withdrawal add geopolitical pressure. In the long run, LEO could become a thriving space economy and national security asset, but near-term leadership depends on timely NASA contracts (up to about $1.5B).
