The BFR (which stands for "Big Falcon Rocket", or "Big F-- Rocket") is created to help humanity settle Mars and other worlds throughout the solar system, Musk has said.
SpaceX revealed the first passenger its signed up to fly to the moon on Monday for one very expensive art project. "I would like to invite six to eight artists from around the world to join me on this mission to the Moon", Maezawa said.
Musk said Maezawa had outlaid a significant deposit and would have a material impact on the cost of developing the BFR, which he estimated at about $5 billion.
Kelly tweeted his good wishes to Maezawa on Tuesday, "Good luck on your trip and if you need someone with a little experience to go with you, my schedule is wide open in 2023".
"All right. Maybe we will both be on it", Musk said to cheers and applause.
Yasaku Maezawa dedicated himself to the Internet fashion industry and is a founding art collector of Tokyo's Contemporary Art Foundation.
Maezawa made his fortune by founding the wildly popular shopping site Zozotown. The Japanese entrepreneur has purchased all the seats on SpaceX's first manned flight around the moon, though no date for the trip has been set.
"If I'm going to go to space, I'd rather go as far as I can", he said.
"If you hear from me, please say yes", the Japanese tycoon pleaded. In a recent episode of This American Life, he said he was entirely unmoved by the concept of space travel, the idea of traveling to the moon, and what those of us on Earth might think of as the beauty of space. It's still unclear as to how Maezawa plans to choose these artists.
But so far this year, his space firm has also kept up a schedule outpaced only by the Chinese government, making 15 launches with its Falcon 9 rocket.
"I know that sounds insane, and we don't usually meet our time lines, but I wanted you to know at least order of magnitude, that's what we're thinking", Shotwell said.
This isn't the first time Musk has vowed to send tourists around the Moon.
Its plan to fly tourists around the moon has also been delayed.
Interestingly, we're about to enter a roughly 10-month period that will mark the 50-year anniversary of not just the lunar landing, but a series of five Apollo launches in quick succession that led to the most famous, Apollo 13.
After an uncrewed demonstration flight this fall and an in-flight abort test, U.S. Air Force Colonel Bob Behnken and former Marine Corps test pilot Doug Hurley will be the first two astronauts to fly in SpaceX's Crew Dragon.
SpaceX investor and private astronaut, Richard Garriott, who spent 11 days visiting the International Space Station, in 2008, said those who were aboard the spacecraft would experience the "overview effect" - a profound shift in perspective when seeing Earth from space.
The company noted that the trip will last about a week. However, he did not reveal the total price of the tickets.
