BENTONVILLE, Arkansas—The first civilian spacewalk, an on-orbit symphony performance, and nearly 40 scientific research experiments. Those were just a few highlights of September’s Polaris Dawn mission: a five-day, four-person orbital spaceflight purchased from SpaceX and commanded by Jared Isaacman, the billionaire CEO of Shift4 Payments.
But Isaacman—now a SpaceX “frequent flier” after also taking part in 2021’s Inspiration4 mission, the first all-civilian spaceflight—is just getting started.
