They will have to test their full fledged Starship first. It hasn't taken flight yet.

The 8 chosen by Maezawa will have to satisfy all the training and be certified before they can go on the round the Moon flight.

This won't be an orbital flight this time.

I am surprised Yozo Hirano isn't on the list. He did quite well on the Soyuz flight documenting everything. He would be a best asset to the round the Moon flight if it ever happens.

2023 I'll say no chance. Probably 2025... maybe.

He should have booked Artemis/Orion. NASA took civilians to the ISS. The private funds would have helped I am sure.

Japanese billionaire entrepreneur Yusaku Maezawa said Friday K-pop artist Top and American DJ Steve Aoki will be among the eight crew members who will join him on a private space trip to orbit the Moon in 2023.

Maezawa, who became the first Japanese civilian to travel to the International Space Station last year, revealed on Twitter and on a website the names of people with whom he will journey as part of the "dearMoon" project. They will ride on a spaceship being developed by U.S. firm SpaceX.
