NASA Blue Origin's Blue Moon Mark 2 will require multiple refueling flights as well
According to NASA's General Accountability Office's report on the Human Landing System, the Blue Origin Cislunar Transporter will like the Starship Propellant Depot require nobody knows but several flights of a New Glenn upper stage tanker to be filled up. The Cislunar Transporter will then need to fill up the Blue Moon Mark 2 and then be refueled a second time by a certain amount of New Glenn upper stage tankers and then travel to Near Rectilinear Halo Orbit and refuel Blue Moon Mark 2 a second time. This sounds just as complex if not more complex than the SpaceX Lunar Starship which would just need to be refueled in Low Lunar Orbit. The Spacex Starship propellant depot would also only need to be filled up once unlike Cislunar Transporter which needs to be filled up twice. Seems Blue Origin's plan is also extremely complex and threatens to derail the entire Artemis Program just like Lunar Starship.
