Who exactly is Jared Isaacman — and why has Donald Trump chosen him again to lead NASA? The 42-year-old billionaire, pilot, and private astronaut has built his career on breaking boundaries both in business and beyond Earth. After making his fortune through a payment processing company he founded as a teenager, Isaacman became one of the most visible figures in commercial space travel — notably as the first non-professional astronaut to walk in space and as the financier behind SpaceX's Inspiration4 mission in 2021.
