The oath was taken during a ceremony held at the Eisenhower Executive Office Building in Washington.
As NASA administrator, Isaacman will lead the agency in bold pursuit of exploration, innovation, and scientific discovery.
“I am deeply honored to be sworn in as NASA administrator,” said Isaacman. “NASA’s mission is as imperative and urgent as ever — to push the boundaries of human exploration, ignite the orbital economy, drive scientific discovery, and innovate for the benefit of all of humanity. I look forward to serving under President Trump’s leadership and restoring a mission-first culture at NASA — focused on achieving ambitious goals, to return American astronauts to the Moon, establish an enduring presence on the lunar surface, and laying the groundwork to deliver on President Trump’s vision of planting the Stars and Stripes on Mars.”
Isaacman, nominated by President Donald J. Trump on Nov. 4th, was confirmed to serve as NASA administrator by the U.S. Senate on Dec. 17. Isaacman is expected to address the workforce this week.
Jared “Rook” Isaacman is the 15th administrator of NASA, a pilot, astronaut, seasoned entrepreneur, philanthropist, and pioneer in commercial spaceflight. Read Isaacman’s official biography online.
