> ome of it isn't even seriously on the drawing board yet Citation needed. NASA specifically called out in their report that SpaceX had done a huge amount of work on refueling already and they were impressed with the amount of detail. NASA has also handed out contracts to study fluid dynamics of cryo and SpaceX got a contract to study that. This is not some mystical thing. Refuling in orbit has been done for 50 years. Yes, its now cryo fluids but pumping cryo around in orbit is already required for upper stages, so its not really even that new or different. And btw, refueling Starship is a required part of Artemis if you want to transition crew in earth or lunar orbit.
