Yusaku Maezawa: The Japanese billionaire who wants to fly to the Moon
My comment
SpaceX's Elon Musk set to announce first private passenger flight around the moon.
I didn't know this plan because I thought that he Elon always thought about only Mars and then I was very surprised that the first private passenger that he announced was Japanese.
The news must make not only me but Japan and the world happy.
Although some people say that a Japanese man who is chosen because he is rich, there are men who are rich but they are not chosen.
Japan must have a proud that there is a man who is going to go to the moon and I imagine a picture that two astronauts put up flags on the moon that are America and Japan. Thank you, Elon Musk.
