Maezawa will invite six to eight artists of different professional and personal backgrounds - artists who represent the whole of humanity - to join him on the lunar flyby mission... with the only stipulation to their involvement being that they create works thereafter that "inspire the dreamer in all of us".
Maezawa, 42, whose net worth is US$2.3 billion, is the founder and CEO of Japan's largest e-commerce company Start Today Co.

"Some of Earth's greatest talents will board a spacecraft and be inspired in a way they have never been before", Maezawa's new #dearMoon website reads. Maezawa has been active in the art community for some time, including establishing the Contemporary Art Foundation in 2012 to support young artists.
