NASA has released a draft Request for Proposals (RFP) for privately operated space stations in low-Earth orbit. This action is part of the agency's preparations for the period following the planned end of the International Space Station (ISS) in 2030.

NASA Administrator Jared Isaacman stated in a news release, "NASA's review reflects what we've been hearing from industry throughout this process. Industry believes it can meet the timelines and that a viable commercial marketplace exists where NASA is one customer among many." He added, "We're focused on supporting those efforts, enabling the capabilities that make this transition possible, and doing all we can to ensure the United States maintains a continuous human presence in low Earth orbit."

The agency previously provided funding to three companies, including $140 million to Axiom Space, to develop concepts for space stations. Key players in the private space station sector include Axiom Space, Vast Space, Voyager, Blue Origin, and potentially SpaceX. The draft RFP document is 246 pages long, and one participant estimated it contains more than 3,000 requirements. Among these requirements, NASA's chief information officer must approve all software purchases made by a company.

Phil McAlister, NASA's former chief of commercial spaceflight, noted the complexity of the draft RFP. "It's got all the requirements, deliverables, and clauses of a cost-plus contract, but they are stuffed into a firm fixed-price bag," McAlister said. He stated, "At least the draft RFP is out now, so industry finally knows what NASA is asking of them." McAlister also said in a podcast interview, "But the budget and lack of a long-term contract shows that NASA is still not fully committed to this program."

Sean Duffy, who served as NASA's interim administrator, previously issued a directive indicating changes to the program due to a budget shortfall. NASA had considered building a core module for private space stations to dock to, but later discarded that idea. NASA will accept feedback from the U.S. space industry on the draft Request for Proposals.

Why It Matters

NASA's initiative to solicit proposals for privately operated space stations marks a shift in its approach to human spaceflight in low-Earth orbit, moving away from direct operation of facilities like the ISS. This transition is framed by an established end date for the International Space Station in 2030, necessitating a commercial successor to maintain continuous U.S. presence in space. The financial and regulatory terms outlined in the lengthy draft Request for Proposals, including software approval requirements and the contract structure, will shape the feasibility and structure of future commercial space endeavors and the industry's ability to meet the timelines for replacement infrastructure.
