Billionaire investor Isaacman has been confirmed as the new administrator of the National Aeronautics and Space Administration, capping an unusual nomination process where Trump put his name forward, withdrew it, and then put him forward again.
Isaacman, an private pilot who was the first private citizen to perform a spacewalk, is also the first agency head in many years to come straight from outside public service.
For many, the success of his time in office will be decided by one key benchmark: if NASA can return humans to the Moon in advance of the Chinese space program.
The administration has emphasized a goal for the US to build a sustained presence on the moon, both to facilitate resource extraction and to act as a launching pad for missions to the Red Planet.
On Wednesday, the U.S. Senate approved his appointment with a bipartisan vote.
Trump initially pulled the nomination in the spring, referencing a "thorough review of past connections".
At the period, the president was engaged in a dispute with Elon Musk, one of his major contributors, with whom the nominee has a working relationship.
The new administrator indicates he is now aligned with the administration's goal to mine the moon, placing him in disagreement with Musk, who has argued that going to the Moon is a diversion from the primary objective of Martian exploration.
In the current space battle, nations are competing to tap into the Moon.
“This is not the time for hesitation but a time for action because if we fall behind, if we make a mistake, we may never catch up, and the consequences could alter the strategic equilibrium here on our planet,” he told lawmakers during his hearing.
The business leader sees introducing more private sector competition as crucial for accomplishing those targets, according to a circulated paper detailing his vision for NASA.
In his testimony, he stood by the plan, which he developed when he was first nominated, but clarified it was a work in progress.
His openness to rivalry could also cause friction with SpaceX. Recently, he praised the award of a major contract to Jeff Bezos's company, which is one of the few rivals of Musk's SpaceX.
In the leaked plan, he proposed the agency should increasingly partner with universities and academic institutions, positioning the agency as a "force multiplier for scientific discovery".
He cited the planned 2027 launch of the Nancy Grace Roman Space Telescope as a flagship example.
"And if we be on the verge of something remarkable - like launching Roman - I will leave no stone unturned to get the program to the pad, even providing personal financing if that's what it requires to deliver the discoveries," he stated.
According to analyses, his wealth is estimated at approximately $1.2bn, primarily derived from his financial services firm and the sale of his business that provided flight training and managed a private fleet of military jets.
The NASA administrator role will be his maiden role in public office, a break from the previous two appointees who served as NASA chief.
He will take over from the former transportation secretary, who has served as acting administrator since the summer.
