Entrepreneur Isaacman has been formally approved as the next chief of NASA, concluding an extraordinary nomination process where President Donald Trump nominated him, pulled the nomination, and then put him forward again.
The billionaire, an amateur jet pilot who was the first non-professional astronaut to perform a extravehicular activity, is also the first NASA administrator in a generation to come entirely from outside government.
For numerous observers, the legacy of his leadership will be judged on one pivotal challenge: if NASA can send astronauts to the lunar surface ahead of China.
The administration has made clear a goal for the US to establish a lasting moon outpost, both to allow for harvesting materials and to function as a launching pad for travel to Mars.
On This week, the U.S. Senate confirmed the nomination with a 67-30 vote.
The President initially pulled Isaacman's nomination in the spring, pointing to a "deep dive of prior associations".
At the period, the president was publicly feuding with the SpaceX CEO, one of his biggest supporters, with whom the nominee has a working relationship.
The new administrator has stated he is now completely supportive of the presidential objective to mine the moon, creating a divergence from Musk, who has said that lunar missions is a diversion from the goal of reaching Mars.
In the ongoing space battle, world powers are vying to exploit the Moon.
“This is not the time for delay but a time for progress because if we lose ground, if we err, we may never catch up, and the consequences could change the global dynamics here on our planet,” Isaacman told US Senators earlier this month.
The private sector veteran sees bringing in more private sector competition as crucial for achieving those objectives, according to a recently leaked document laying out his strategy for the agency.
In his testimony, he reaffirmed the plan, which he developed when he was initially selected, but said it was a work in progress.
His welcoming of competition could also create a conflict with SpaceX. Recently, Isaacman applauded the granting of a significant agreement to Jeff Bezos's company, which is one of the primary competitors of SpaceX.
In the strategy paper, he recommended the agency should forge stronger ties with research institutes, envisioning the agency as a "amplifier for scientific discovery".
He highlighted the scheduled 2027 launch of the Roman Space Telescope as a prime illustration.
"And if we be close to something remarkable - like launching Roman - I will consider all avenues to get the program to the pad, even funding it myself if that's what it takes to produce the science," he remarked.
According to reports, Isaacman's net worth is estimated at approximately 1.2 billion dollars, accumulated through his payment processing company and the sale of his business that provided flight training and operated a collection of military aircraft.
The position of agency chief will be his first job in politics, a contrast to the previous two appointees who served as NASA chief.
He will succeed the former transportation secretary, who has been the interim NASA chief since the summer.
