Isaacman's nomination to serve as the next administrator of NASA came on Dec. 4. Donald Trump, in his first space-related move ahead of his incoming second administration, noted Isaacman's business achievements and stated his belief that the private astronaut could spur on the agency.

Unlike previous NASA administrators, Trump’s pick for the role isn’t a politician, scientist or engineer, but a billionaire entrepreneur.

Jared Isaacman planned two more missions with SpaceX, including Starship's first crewed flight. Trump has thrown his Polaris Program into question.
