NASA acting administrator Sean Duffy made two television appearances on Monday morning in which he shook up the space agency’s plans to return humans to the moon. Duffy also indirectly acknowledged that NASA’s projected target of a 2027 crewed lunar landing is no longer achievable. I think we’ll see companies like Blue [Origin] get involved, and maybe others. In their funded contracts for reusable landers, SpaceX and Blue Origin must refuel their vehicles in low-Earth orbit, something that has never been done on a large scale. Rather he is almost certainly referring to a plan developed by Blue Origin that uses multiple Mk 1 landers, a smaller vehicle originally designed for cargo only.
