Maezawa announced the project in 2018 and later selected eight crew members — including musicians, athletes, and content creators — for a planned trip around the Moon and back.
The flight is planned aboard SpaceX's still-in-development Starship vehicle.
The exact price was never disclosed, but is widely estimated in the hundreds of millions of dollars.
Enough for Maezawa to not only buy his own ticket to the Moon, but to comp eight other people's seats along with him.
