A high-stakes contest for NASA’s next permanent Administrator is unfolding, pitting billionaire private astronaut Jared Isaacman against Secretary of Transportation Sean Duffy. The decision, which rests solely with President Donald Trump, has sparked intense debate and public maneuvering, leaving the forward plan of America’s space agency hanging in the balance.
Historically, each new U.S. president appoints a NASA Administrator to steer the agency through their term. President Obama selected Charles Bolden, Trump chose Jim Bridenstine in his first term, and Biden appointed Bill Nelson. However, Trump’s second term, which began after his victory in November 2024, has taken a tumultuous path toward filling this critical role.
During his first term, it took 458 days for Bridenstine to assume office—the longest NASA has ever operated without a permanent leader. This time, Trump moved faster, announcing on December 4, 2024, his intent to nominate Jared Isaacman, a billionaire entrepreneur, two-time private astronaut, and philanthropist known for raising over $250 million for St. Jude Children’s Research Hospital during the Inspiration4 mission.
The nomination, reportedly influenced by SpaceX CEO Elon Musk, was formalized on January 20, 2025, after Trump’s inauguration as the 47th President.
With Isaacman’s nomination, Janet Petro, director of the Kennedy Space Center, stepped in as NASA’s Acting Administrator.

Isaacman cleared a significant hurdle on April 9, 2025, passing the Senate Committee on Commerce, Science, and Transportation with a 19-9 vote on April 30. Only a final Senate vote stood between him and the role. But political turbulence derailed the process.
A public rift between Trump and Musk, compounded by an earlier falling-out between Musk and Sergio Gor, then-Director of the White House Presidential Personnel Office, shifted the landscape.
In May 2025, Gor presented Trump with a file highlighting Isaacman’s past donations to the Democratic Party—publicly known information that nonetheless prompted Trump to label Isaacman “totally Democrat” and withdraw his nomination. NASA was left with Petro as Acting Administrator and no permanent replacement in sight.
In a surprising turn, Trump appointed Secretary of Transportation Sean Duffy as NASA’s new Acting Administrator in July 2025. Duffy, a close ally of the President, received unexpected support from Isaacman, who even flew Duffy in his MiG-29 fighter jet at the EAA AirVenture Oshkosh air show in July.
Duffy quickly embraced the role, making frequent media appearances to discuss ambitious NASA initiatives, such as nuclear power on the Moon and the Artemis II and III missions. His high-profile presence contrasted with challenges at the Department of Transportation, where opportunities for positive press are less abundant.
The plot thickened in late August when Gor was appointed Special Envoy for South and Central Asian Affairs and U.S. Ambassador to India, vacating his White House role. On October 9, Bloomberg reported that Trump and Isaacman had met to discuss reviving his nomination, a claim Reuters later corroborated, noting Isaacman’s discussions with Duffy.
However, Duffy appears reluctant to relinquish the Acting Administrator role. Media reports suggest he has been lobbying space industry leaders for support to secure the permanent position, while publicly criticizing SpaceX’s delays in developing the Starship lunar lander for Artemis III.
Notably, Duffy has remained silent on similar delays with Axiom Space’s spacesuits, fueling speculation of strategic maneuvering.
Duffy’s recent proposal to fold NASA into the Department of Transportation, alongside agencies like the Federal Aviation Administration, has drawn sharp criticism. Opponents argue that NASA’s mission of space exploration and aeronautics does not align with transportation-focused agencies, and such a move would end NASA’s status as an independent entity.
Elon Musk has been vocal in his opposition, launching personal attacks on Duffy, calling him “Sean Dummy” and “Sean ‘Dangerously Stupid’ Dummy” on social media. Musk has questioned Duffy’s qualifications, stating, “The person responsible for America’s space program can’t have a 2 digit IQ,” while clarifying he is not explicitly endorsing Isaacman but seeks a “3 digit IQ” leader.
Isaacman, meanwhile, has maintained a low profile, with his only recent NASA-related social media post being a tribute to Apollo 8’s Earthrise photo on astronaut Bill Anders’ birthday. As the one-year anniversary of the 2024 election approaches, the question of NASA’s permanent leadership remains unresolved.
With Duffy’s aggressive lobbying and Isaacman’s quiet diplomacy, the decision lies with President Trump, who has remained silent on the matter. One thing is certain: a resolution is imminent, and its outcome will shape NASA’s future.
