What We Know About NASA's Push for Private Space Stations

NASA on Friday released a 360-page request for proposals asking the US commercial space industry to build private space stations in low-Earth orbit, according to Ars Technica. The agency wants a replacement ready as early as 2030, when the International Space Station is expected to retire.

What did NASA release Friday?

NASA issued a formal "request for proposals" to industry, Ars Technica reported. A cover letter attached to the 360-page document said the goal is to "ensure NASA has a sustained human presence in LEO for crew members to perform science and exploration." Industry responses are due back to NASA on December 8, per the outlet.

NASA Administrator Jared Isaacman framed the move as a continuation of US orbital presence, not a retreat. "We've made it clear that NASA will never give up its presence in low Earth orbit," Isaacman said in a statement cited by Ars Technica. "We will continue to need a place to conduct research, develop technologies, train crews, and prepare for missions to the Moon and Mars."

Who is expected to bid?

Axiom Space, Voyager Space and Vast Space are likely bidders, Ars Technica reported. Blue Origin won funding in an earlier round of the program, but the outlet said questions remain about the company's continued commitment. SpaceX appears unlikely to bid for now, according to the report.

How will astronauts get to the stations?

Transportation was one of the most closely watched parts of the solicitation, Ars Technica reported. NASA had previously signaled it might leave crew transport up to the station operators themselves, asking them to sell an end-to-end service. That approach runs into a problem: SpaceX has said it plans to retire its Crew Dragon spacecraft once the ISS deorbits, expected in 2030 or 2032, and the company has not offered to sell seats to private station operators, per the outlet. SpaceX currently operates the only US crew vehicle capable of reaching orbit.

That gap is part of why NASA added $359 million in funding two weeks ago to support Boeing's transportation work, Ars Technica reported.

What happens next in the process?

NASA said it plans to select "two or more" contractors in this phase and expects to make a final decision in April, according to the outlet. Winners in this first phase are guaranteed at least $100 million. The program, called Commercial LEO Destinations, moves into a second phase next year covering development and certification funding. A third phase will involve NASA buying at least four crewed missions to the private stations, Ars Technica reported. Future phases of the contract will be worth billions, per the report.

Why does NASA say private stations matter?

Isaacman said commercial stations let NASA redirect resources toward harder goals. "Commercial space stations may provide that capability while creating new opportunities for American industry and allowing NASA to concentrate more of our resources on the near-impossible missions ahead," he said, according to Ars Technica. The agency's full solicitation document was referenced in the report but not published at a separate public link as of this writing.
