During an event at SpaceX headquarters on Sept. 17, 2018, SpaceX CEO Elon Musk and Japanese entrepreneur Yusaku Maezawa playfully discuss the prospect of flying together on SpaceX’s mission around the moon, which could happen as early as 2023. Maezawa has bought all the seats aboard a SpaceX BFR vehicle for the trip and plans to bring six to eight artists along with him; he has asked Musk to come as well.
