Jared Isaacman is Donald Trump’s nominee to be administrator of NASA. Isaacman, 44, is the billionaire CEO of Shift4, a payment processing company he started at age 16 in his parents’ basement in New Jersey. He is also a pilot and a commercial astronaut with Elon Musk’s SpaceX. In 2021, Isaacman self-funded a three-day SpaceX mission to space called Inspiration4, marking the first space flight manned by civilians rather than government astronauts, and the first private astronaut to conduct a spacewalk. A confirmation hearing has not yet been scheduled.
