“Jared’s passion for space, his experience as an astronaut, and his drive to explore new frontiers, unlock the mysteries of the universe, and advance the new space economy make him the ideal person to lead the National Aeronautics and Space Administration (NASA),” President Trump said on November 4.
If approved by the U.S. Senate, Isaacman would replace Transportation Secretary Sean Duffy, who has been serving as NASA’s acting administrator. Trump had previously nominated Isaacman to the same position but rescinded the decision in May, amid a heated dispute between the president and Elon Musk over the “One Big Beautiful Budget Act” (OBBBA).
At the time, the White House cited Isaacman’s prior support for Democrats as the reason, though U.S. media suggested it was in fact a move targeting Musk, given the two men’s close relationship.
SpaceX CEO Elon Musk reposted Trump’s nomination announcement on X (formerly Twitter), adding heart, rocket, and American flag emojis.
Isaacman, 42, is the founder and CEO of Shift4 Payments, a Pennsylvania-based payment processing company, as well as a skilled pilot. He made history in September 2024 as the first private astronaut to conduct a spacewalk during SpaceX’s Polaris Dawn mission.
Isaacman has taken part in several private spaceflights aboard SpaceX rockets and is a major customer and supporter of the company’s space exploration goals.
Musk is believed to have lobbied President Trump to help Isaacman become NASA’s chief, raising questions about potential conflicts of interest.
Elon Musk, the world’s richest man, was once a close ally of President Trump, having invested heavily in his campaign and been tasked with reducing government spending. Their relationship later soured over disagreements surrounding the OBBBA, a budget and tax-cut bill. Musk later called Trump to reconcile, admitting that he regretted some of his past “over-the-line” social-media posts.
President Trump has denied claims that he sought to harm Musk’s businesses after their dispute, emphasizing that he wants them to “grow stronger than ever.”
The two men spoke again during a memorial event for activist Charlie Kirk on September 21, marking their first public conversation since the conflict—an event observers see as a sign that their relationship has begun to “thaw.”
