WASHINGTON: The U.S. Senate on Wednesday confirmed billionaire private astronaut Jared Isaacman as NASA administrator, making him the space agency’s 15th leader under President Donald Trump. Isaacman, a vocal advocate for Mars exploration and a former associate of SpaceX CEO Elon Musk, was approved by a 67–30 vote.
The confirmation came two weeks after Isaacman told senators during his second hearing that NASA must accelerate its efforts to beat China back to the Moon this decade. Trump had earlier withdrawn and then renominated Isaacman for the role this year.

Isaacman will now lead NASA’s workforce of roughly 14,000 employees as the agency invests billions into its most ambitious mission in decades. Central to that effort is the Artemis program, which aims to return humans to the Moon to establish a long-term presence before eventually sending astronauts to Mars.
His appointment comes amid significant changes at the agency. As part of a White House efficiency push led by Elon Musk, NASA’s workforce has been cut by about 20%, and the administration has proposed reducing the agency’s 2026 budget by roughly 25% from its usual $25 billion. These cuts have raised concerns about the future of multiple space science programs.

Isaacman has outlined plans to place greater emphasis on Mars missions while continuing the Artemis effort. He has also called for increased reliance on private companies such as SpaceX, arguing this approach could reduce costs and foster competition.
Sixteen Democrats joined 51 Republicans in voting for Isaacman, while all 30 opposing votes came from Democrats. Senator Maria Cantwell, the ranking Democrat on the Senate Commerce Committee, supported the confirmation despite criticizing proposed cuts to NASA’s science programs.

Some Democrats have expressed concern about Isaacman’s close ties to Musk, whose company holds about $15 billion in NASA contracts. Meanwhile, lawmakers from both parties have stressed urgency as China plans to land astronauts on the Moon by 2030.
