NASA Opens Formal Competition for Commercial Space Stations with Final RFP

NASA on Friday released its final request for proposals for next-generation commercial space stations, formally opening competition for privately operated successors to the International Space Station as the agency works toward retiring the ISS around 2030.

The solicitation asks U.S. companies to submit plans for commercial destinations in low Earth orbit, the region of space a few hundred miles above Earth where the ISS operates today. Proposals are due Dec. 8, and NASA said it expects to make contract awards in spring 2027.

The step matters because it moves NASA’s long-planned ISS transition into a formal procurement phase. Rather than continuing to own and operate a government-led station indefinitely, NASA wants commercial companies to provide orbital destinations and transportation services, with the agency becoming one customer among others.

Under the solicitation, companies would be responsible for “designing, building, testing, certifying, and operating” stations capable of providing “end-to-end destination and transportation services for human spaceflight use,” according to NASA.

NASA said it intends to use firm-fixed-price, multi-award, indefinite-delivery/indefinite-quantity contracts. In practice, that means the agency expects to choose multiple companies at the outset and pay set prices for work, while ordering specific development and service tasks over time.

The agency said it expects to select two or more contractors through early development. After that, NASA plans to use a competitive task-order process for later phases, including final design, test and evaluation, certification and services needed to support research and exploration in low Earth orbit after the ISS.

NASA Administrator Jared Isaacman said the effort is tied to the agency’s goal of preserving a continuous American foothold in orbit after the current station is retired.

“In alignment with the President’s National Space Policy, NASA is committed to maintaining a sustained American presence in low Earth orbit long after the International Space Station retires,” Isaacman said in the agency’s announcement. “We will continue to need a place to conduct research, develop technologies, train crews, and prepare for missions to the Moon and Mars.”

The transition timeline carries real risk. In a June report, the Government Accountability Office, the congressional watchdog agency, said NASA plans to deorbit the ISS by the end of 2030 and shift to commercial stations. The same report warned that NASA had not documented the likelihood or expected length of a possible gap in continuous human presence in low Earth orbit if commercial replacements are not ready on time.

GAO also said NASA’s target is for commercial stations to demonstrate crewed capability no later than 2030, underscoring how narrow the schedule could become if development slips.

That makes Friday’s announcement more than a routine contracting milestone. NASA is not just seeking concepts; it is starting the process for the systems it hopes will replace one of the most important pieces of U.S. space infrastructure. If the transition stays on schedule, astronauts would move from a government-led station to commercially owned and operated outposts where NASA buys research, crew and other services. If it does not, the agency could face a break in uninterrupted U.S. human activity in low Earth orbit.

NASA said the final request for proposals follows months of industry outreach. The agency issued two requests for information in March, then released a draft RFP in July, and also held an industry day and one-on-one meetings with companies before publishing the final solicitation Friday.
