The era of commercial space stations is set to begin in 2026, as private companies prepare to launch their own orbital outposts following the planned retirement of the International Space Station. These ventures aim to fill the gap left by the ISS and foster a new economy in low Earth orbit. Experts anticipate innovation and cost reductions driven by competition among providers.
For nearly three decades, the International Space Station (ISS) has served as the sole destination for astronauts and experiments in low Earth orbit. However, with NASA and its partners planning to deorbit the ISS by the end of the decade, commercially owned stations are stepping in to maintain human presence in space.
"These have been in development for a number of years now, mostly in partnership with NASA, and 2026 is really going to be the start of hardware flying," says Mary Guenther, head of space policy at the Progressive Policy Institute in Washington DC. While private modules have previously attached to the ISS, such as those from the now-defunct Bigelow Aerospace, no standalone commercial stations have launched until now.
Leading the charge in 2026 is startup Vast, which plans to send its Haven-1 station into orbit atop a SpaceX Falcon 9 rocket as early as May. Smaller and simpler than the ISS, Haven-1 will depend on SpaceX's Crew Dragon capsule for life support and can accommodate four crew members. It features a photography dome and wi-fi for space tourism and microgravity research, serving as a precursor to the more ambitious Haven-2, envisioned as an ISS successor.
"I think everybody, Vast included, is driving towards 2030," notes Colin Smith at Vast. "The ISS is coming down at the end of 2030, so people are looking at their calendars going: 'Uh-oh, it’s 2025, we should do something.'"
Meanwhile, Sierra Space intends to launch a prototype of its Large Integrated Flexible Environment module in 2026. This expandable habitat will form part of the Orbital Reef project, led by Blue Origin and Sierra Space, alongside their Dream Chaser space plane.
The shift to commercial stations promises diversity, with multiple models targeting varied markets. Guenther highlights the potential for competition to spur innovation: "I’ll be really excited to see how they differentiate from one another to attract business and how that competition between them will drive innovation. Hopefully iron will sharpen iron."
Proponents argue these stations could slash costs compared to the ISS, which has cost around $150 billion to house just seven people. "Our long-term goal is getting millions of people living and working in space," Smith adds. Emerging industries like pharmaceuticals and materials may transition to these platforms, though their commercial viability remains to be proven as launches begin.
