Billionaire investor Jared Isaacman has been voted in as the next chief of NASA, ending an unusual confirmation journey where Trump nominated him, pulled the nomination, and then submitted his name once more.
Isaacman, an aviation enthusiast who became the first civilian to undertake a spacewalk, is also the first agency head in decades to come straight from outside government.
For many, the ultimate measure of his leadership will be judged on one pivotal challenge: whether it can return humans to the Moon in advance of the Chinese space program.
Trump has made clear a desire for the US to establish a lasting moon outpost, both to facilitate resource extraction and to act as a stepping stone for missions to the Red Planet.
On Wednesday, the Senate confirmed the nomination with a decisive vote.
Trump first withdrew the nomination in May, pointing to a "deep dive of past connections".
At the period, the president was engaged in a dispute with the SpaceX CEO, one of his biggest supporters, with whom the nominee has business connections.
Isaacman indicates he is now aligned with Trump's mission to mine the moon, placing him in disagreement with Elon Musk, who has said that lunar missions is a distraction from the journey to travelling to Mars.
In the current cosmic competition, world powers are competing to exploit the lunar surface.
âNow is not the time for delay but a time for decisive steps because if we fall behind, if we stumble, we may not recover, and the consequences could change the global dynamics here on our planet,â Isaacman told the Senate committee during his hearing.
The private sector veteran sees fostering more commercial rivalry as key to achieving those targets, according to a recently disclosed paper outlining his strategy for NASA.
In his testimony, he stood by the strategy, which he crafted when he was first nominated, but said it was a evolving strategy.
His openness to multiple providers could also cause friction with SpaceX. Last week, Isaacman 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 suggested NASA should increasingly partner with universities and academic institutions, envisioning the agency as a "force multiplier for scientific discovery".
He pointed to the upcoming deployment of the Nancy Grace Roman Space Telescope as a cornerstone project.
"And if we be on the verge of something extraordinary - like launching Roman - I will explore every option to see it launched, even funding it myself if that's what it takes to achieve the science," he remarked.
According to analyses, his wealth is estimated at approximately $1.2 billion, made mostly from his payment processing company and the divestment of his firm that provided flight training and operated a collection of military aircraft.
The position of agency chief will be his first job in government service, a contrast to the last two people appointed as NASA chief.
He will take over from the former transportation secretary, who has been the interim NASA chief since July.
