How long starship to moon?

Under the Artemis architecture NASA has contracted, the crew leaves Earth aboard Orion and meets a lander already parked in lunar orbit. The Starship Human Landing System gets there on its own, uncrewed, and its journey has two parts with no equivalent in Apollo. First it reaches low Earth orbit nearly empty of propellant and is refilled by a series of tanker flights, a campaign whose length depends on how fast those tankers can be launched. Only then does it head for the Moon, and because nobody is aboard it can take a slow, propellant-efficient trajectory instead of a fast one.

For a crewed crossing the schedule is set by people: consumables, radiation exposure and the need to keep return options open. Apollo 11 took just over four days from lift-off on 16 July 1969 to touchdown on 20 July, and the physics has not changed since. For an uncrewed vehicle the schedule is set by propellant instead. Low-energy transfers that loop far out before falling into lunar orbit cut the braking cost substantially, at the price of weeks rather than days in transit, and a lander that must arrive with full tanks has every reason to accept them.

None of this is routine yet. Propellant transfer in orbit at the scale Starship needs has never been demonstrated between two full-size vehicles, and the number of tanker flights required drives the timeline far more than any coasting time does. That is why schedule questions about Starship and the Moon are answered in launch campaigns rather than in travel time: the transfer itself is a solved problem, the refuelling is not. A crewed Starship flying directly from Earth to the lunar surface is not part of the current plan.
