The identity of the mysterious first passenger aboard SpaceX’s private space venture has been revealed: Japanese internet commerce billionaire Yusaku Maezawa.

SpaceX founder Elon Musk personally made the announcement at a televised press conference on Monday, held on the construction floor of SpaceX’s Hawthorne, CA rocket assembly building where the rocket will be constructed to take Maezawa and his crew around the moon.

Maezawa will ride aboard SpaceX’s two-stage Big Falcon Rocket (BFR). The cost of his ticket will be put towards the estimated $5 billion cost of developing the rocket.

The 42-year-old online retail mogul has been an emphatic collector of art, reportedly spending $80 million on paintings by painters Pablo Picasso and Jean-Michel Basquait in 2016.

“I choose to go to the moon… with artists!” said Maezawa, parroting former president John F. Kennedy’s famous moonshot speech. Maezawa plans to select eight artists from around the world who he thinks will be able to translate their experience into art.

Building upon the excitement surrounding the planned announcement, Musk unveiled new design plans for the shuttle that will carry crew aboard the BFR. He also announced dramatic progress on the massive carbon-fiber tanks to hold their cryogenic fuel and oxidizer.

Before the moon mission can take place, the rocket must be developed, certified as safe for human travel, and tested along the prospective trajectory to the moon several times. This lengthy process is expected to take at least five years, with the earliest estimated human flight taking place sometime in 2023.

In the meantime, Maezawa plans to select the artistically inclined passengers that will journey with him to the moon and back.
