NASA issues call for private space stations to succeed ISS
NASA has asked US companies to propose private stations to replace the ISS, with responses due 8 December.

NASA has released a request for proposals asking the US commercial space industry to develop private space stations where astronauts can live in low-Earth orbit as early as 2030. The new stations are intended to succeed the International Space Station.
Industry responses are due on 8 December. NASA plans to select "two or more" contractors in this phase of the Commercial LEO Destinations competition, with a final decision expected in April. Phase 1 winners are guaranteed at least $100 million.
NASA said Phase 2 will begin next year and include funding for the development and certification of space stations. Phase 3 will include the purchase of at least four missions for NASA astronauts.
NASA Administrator Jared Isaacman said: "We've made it clear that NASA will never give up its presence in low Earth orbit." He added that NASA will continue to need a place to conduct research, develop technologies, train crews and prepare for missions to the Moon and Mars.
