Trump Names Sean Duffy as Interim NASA Chief Amid Space Policy Shift

President Donald Trump has named Transportation Secretary Sean Duffy as the interim administrator of NASA, a decision underscoring the rising prominence of space exploration in America’s national agenda. Announced on July 9, 2025, this move signals a shift in leadership as Trump navigates the complexities of space policy.

"I’m directing our GREAT Secretary of Transportation, Sean Duffy, to lead NASA, even if just for a short while," Trump declared on Truth Social, praising Duffy’s "tremendous" work in modernizing air traffic control and revitalizing infrastructure. Duffy, a former Wisconsin congressman and staunch Trump ally, embraced the role with gusto, posting on X: "Honored to accept this mission. Time to take over space. Let’s launch!"

This appointment follows the withdrawal of billionaire astronaut Jared Isaacman’s nomination in May, amid concerns over his ties to Elon Musk and SpaceX, which raised conflict-of-interest red flags. NASA, a cornerstone of Trump’s vision for national defense and innovation, continues to play a pivotal role, building on the creation of the Space Force during his first term.

Duffy steps in to replace acting administrator Janet Petro, taking the helm at a time when space is increasingly central to America’s strategic and economic goals.
