Controversial crypto entrepreneur Justin Sun finally got his suborbital ride into space today from Jeff Bezos’ Blue Origin space venture, four years after he put in the winning $28 million bid for a seat.

The mission is the 14th human flight for New Shepard and the 34th in its history overall. The spacecraft will liftoff from a Texas launch site early Sunday morning.

The highest-profile NS-34 passenger is Justin Sun, a 34-year-old billionaire who founded the blockchain platform Tron. In June 2021, Sun won an auction for a seat aboard the first-ever crewed flight of New Shepard, plunking down $28 million. (He did so anonymously; we didn't learn that Sun posted the winning bid until December 2021 .)
