President Donald Trump has renominated entrepreneur and private astronaut Jared Isaacman to serve as administrator of NASA, which some see as a fresh push to revive momentum in America’s space program.
Isaacman, founder of the company Shift4, built that “payment processing” company from a small startup into a huge player in the financial industry. He later became known as one of the first private astronauts to command commercial space missions, including some high-profile flights that demonstrated the new possibilities for non-governmental space travel, such as SpaceX’s missions.
Trump announced the renomination on Tuesday on Truth Social, writing: “I am pleased to nominate Jared Isaacman, an accomplished business leader, philanthropist, pilot, and astronaut, as Administrator of NASA. Jared’s passion for Space, astronaut experience, and dedication to pushing the boundaries of exploration, unlocking the mysteries of the universe, and advancing the new Space economy, make him ideally suited to lead NASA into a bold new Era.”
The nomination had been previously paused earlier this year during a “standard vetting review.”
Isaacman briefly stepped back from pursuit of the NASA role in late May, citing what Trump described as a “thorough review of prior associations.” During that time, Isaacman transitioned from CEO of Shift4 to executive chairman of the financial company.
He wrote a letter to Shift4 investors around that time, saying, “My brief stint in politics was a thrilling experience, and being considered to lead NASA was truly the honor of a lifetime. Even knowing the outcome, I would do it all over again.”
Now, it appears he is back.
Isaacman’s background and friendship with people like Elon Musk align with Trump’s apparent approach of pairing government agencies with private innovation. Some supporters could argue that Isaacman’s entrepreneurial track record and hands-on experience in space could encourage partnerships that reduce costs for taxpayers and speed up technological development in the space sector.
Thank you, Mr. President @POTUS, for this opportunity. It will be an honor to serve my country under your leadership. I am also very grateful to @SecDuffy, who skillfully oversees @NASA alongside his many other responsibilities.

The timing of his renomination comes as the federal government remains in a shutdown that began in early October, as previously detailed in reports by DX. While many government agencies are operating with reduced capacity, the Senate can still proceed with certain Presidential appointments. That procedural window means Isaacman’s confirmation process could continue, while other legislation or political moves remain paused.
Since July, NASA has been led by Acting Administrator Sean Duffy, the Transportation Secretary, who has kept key programs, such as various lunar missions and commercial launch partnerships, on track.
Trump was quick to compliment Duffy when announcing the Isaacman appointment this week, saying, “Sean Duffy has done an incredible job as Interim Administrator of the National Aeronautics and Space Administration (NASA).”
Isaacman’s appointment could mark a shift toward a more aggressive push to expand the commercial space economy and maintain the American advantage in space against other countries, such as China.
The Republican-led Senate will soon decide whether to confirm Isaacman.
States with large NASA hubs and operations, including Texas—home to the Johnson Space Center—remain hopeful that they will benefit from stable leadership at NASA.
If confirmed, Isaacman would take over an agency entering a new phase of exploration, with missions aimed at returning Americans to the moon and pushing deeper into commercial partnerships that may define the future of space travel for the country.
Partnerships that could include a stronger connection with Musk and SpaceX, whose long-term mission isn’t just taking humans back to the moon, but to Mars.
