More than two decades have come and gone since entrepreneur Dennis Tito became the first person to pay for his own ride into space, spending a week on the International Space Station.

After that pioneering mission aboard a Soyuz vehicle, Tito said he always had a desire to return to space, with a preference for flying to the Moon. But this thought remained mostly dormant, because Tito did not have confidence in any of the available spaceflight vehicles for such a mission.

That changed about a year and a half ago when he and his wife, Akiko Tito, visited SpaceX’s headquarters in Hawthorne, California. After a tour, they discussed possible space tourism trips, and it did not take long for the lunar idea to come up. Would Tito be interested in riding aboard SpaceX’s Starship vehicle for a flight around the Moon?
