THE White House on Saturday withdrew its nominee for NASA administrator, Jared Isaacman, abruptly yanking a close ally of Elon Musk from consideration to lead the space agency.
President Donald Trump will announce a new candidate soon, said White House spokeswoman Liz Huston.
"It is essential that the next leader of NASA is in complete alignment with President Trump's America First agenda and a replacement will be announced directly by President Trump soon," Reuters reported her saying.
Isaacman, a billionaire private astronaut who had been Musk's pick to lead NASA, was due next week for a much-delayed confirmation vote before the U.S. Senate. His removal from consideration caught many in the space industry by surprise.
The White House did not explain what led to the decision. Isaacman, whose removal was earlier reported by Semafor, did not return a request for comment.
Isaacman's removal comes just days after Musk's official departure from the White House, where the SpaceX CEO's role as a "special government employee" leading the Department of Government Efficiency created turbulence for the administration and frustrated some of Trump's aides.
Musk, according to a person familiar with his reaction, was disappointed by Isaacman's removal and considered it to be politically motivated.
"It is rare to find someone so competent and good-hearted," Musk wrote of Isaacman on X, replying to the news of the White House's decision.
Musk did not immediately respond to a request for comment.
It was unclear whom the administration might tap to replace Isaacman.
One name being floated is retired U.S. Air Force Lt. General Steven Kwast, an early advocate for the creation of the U.S. Space Force and Trump supporter, according to three people familiar with the discussions.
Isaacman, the former CEO of payment processor company Shift4, had broad space industry support but drew concerns from lawmakers over his ties to Musk and SpaceX, where he spent hundreds of millions of dollars as an early private spaceflight customer.
The former nominee had donated to Democrats in prior elections. In his confirmation hearing in April, he sought to balance NASA's existing moon-aligned space exploration strategy with pressure to shift the agency's focus on Mars, saying the U.S. can plan for travel to both destinations.
As a potential leader of NASA's some 18,000 employees, Isaacman faced a daunting task of implementing that decision to prioritize Mars, given that NASA has spent years and billions of dollars trying to return its astronauts to the moon.
On Friday, the space agency released new details of the Trump administration's 2026 budget plan that proposed killing dozens of space science programs and laying off thousands of employees, a controversial overhaul that space advocates and lawmakers described as devastating for the agency. - June 1, 2025
