NASA has overhauled its plan to replace the International Space Station (ISS), citing a $4 billion shortfall in funding. The agency’s previous strategy involved issuing a request for proposals, but it will now adopt a new approach.
In his first official task as Acting Administrator, Sean Duffy signed a directive aimed at addressing concerns about the program’s success. The plan has been modified to alter its strategy and meet the proposed budget.
The original plan required NASA to select one or two companies to move forward with station assembly and certification before flight. However, with funding reduced by up to $4 billion, the agency must now adjust its approach.
Under the new plan, no specific companies will be selected initially. Instead, NASA aims to provide a framework for commercial space stations to develop their own proposals, allowing multiple firms to participate in the program.
