NASA has released its final request for proposals for commercial space stations in low Earth orbit. The agency’s October 9 announcement invites industry to present plans for destinations and transportation services that could support research and human spaceflight after the International Space Station retires.
The solicitation covers development, testing, certification, and operation. NASA said proposals are due December 8, with awards expected in spring 2027. Its planned contracting approach would support multiple companies in early development before further competition for later stages.
The announcement follows earlier requests for industry input on destinations and transportation. NASA describes commercial stations as a way to maintain a research presence near Earth while supporting other exploration goals. Companies considering participation should consult the original release and linked solicitation for the controlling requirements and any subsequent changes.
