The ultra-cold propellants, which continually boil away, must first be transferred, one flight at a time, to a storage vehicle of some sort. When enough propellant is available, the HLS will be launched, refueled from the depot and then take off for the moon where it will ...

To get to the moon, the HLS must be refueled. SpaceX plans to launch a Starship propellant depot and multiple "tankers" to fill it with the required methane and liquid oxygen. The HLS vehicle then would attach itself to the depot, take on propellants and then head for the moon to await...
