Historically, choosing the chief of NASA has not been a prime precedence for incoming presidential administrations. Whereas nominations for cabinet-level posts are introduced properly earlier than Inauguration Day, the selection of a NASA administrator can languish for months. President Joe Biden’s nomination of Invoice Nelson to steer the house company took till March 2021 and was relatively speedy, comparatively talking: in 2017, Donald Trump waited greater than seven months earlier than choosing Jim Bridenstine as NASA administrator.
That was one motive why Trump’s announcement on the morning of Dec. 4 — a month and a half earlier than his second Inauguration Day — was so stunning. “I’m delighted to appoint Jared Isaacman, an achieved enterprise chief, philanthropist, pilot, and astronaut, as Administrator” of NASA, he posted on social media. “Jared will drive NASA’s mission of discovery and inspiration, paving the best way for groundbreaking achievements in Area science, know-how, and exploration.”
The timing of the announcement was not the one shock. Isaacman is an outsider to civil house, with few recognized interactions with NASA. He’s most acquainted to the house neighborhood because the billionaire funder, and commander, of two non-public astronaut missions on SpaceX’s Crew Dragon spacecraft. His choice suggests the incoming Trump administration is involved in shaking up how NASA operates, with maybe a larger concentrate on business approaches. That will imply revisiting NASA’s present method to the Artemis lunar exploration program, one which depends extensively on conventional contractors and contracting approaches. Nonetheless, any try at radical modifications to the company will doubtless face vital opposition from Congress.
From dropout to billionaire astronaut
Earlier than 2021, few within the house business had heard of Isaacman. A highschool dropout (he later obtained a bachelor’s diploma from Embry-Riddle Aeronautical College), he began a cost processing firm in 1999 as a teen in his mother and father’ basement. That firm, now generally known as Shift4, generated greater than $2.5 billion in income in 2023 and went public on the New York Inventory Change in 2020, giving Isaacman an estimated web value of about $2 billion.
In January 2021, SpaceX introduced an settlement with Isaacman for a personal astronaut mission on the corporate’s Crew Dragon spacecraft. The four-person Inspiration4 mission flew in September 2021 with Isaacman, who has in depth expertise piloting high-performance plane, as commander. The three-day mission demonstrated that non-professional astronauts may fly safely in Crew Dragon.
A number of months after Inspiration4, Isaacman and SpaceX introduced a brand new initiative dubbed the Polaris Program. It referred to as for a collection of personal astronaut missions beginning on Crew Dragon and culminating within the first crewed launch of Starship. The primary of these missions, Polaris Daybreak, flew in September 2024, once more commanded by Isaacman. That five-day Crew Dragon flight included the primary non-public spacewalk, with Isaacman and one other crewmember, Sarah Gillis, briefly exiting the spacecraft to check SpaceX-developed spacesuits.
All through the Inspiration4 and Polaris Daybreak missions, Isaacman expressed little public curiosity in house coverage or politics on the whole. Few, if any, folks within the business had his title on a shortlist of potential NASA directors on the time of Trump’s announcement.
Isaacman, although, has been energetic as a contributor to political events and candidates, together with many Democrats. In response to OpenSecrets.org, which maintains marketing campaign finance databases, Isaacman made donations in 2024 to the Democratic occasion organizations in Michigan and Pennsylvania in addition to two Democratic political motion committees. In 2023, he donated to George Whitesides, a Democrat and former Virgin Galactic chief govt who received a Home seat in Southern California in 2024. He additionally contributed to the reelection marketing campaign of Sen. Mark Kelly (D-Ariz.), a former NASA astronaut, in 2022. He has beforehand contributed to Republicans, together with Rep. Sam Graves (R-Mo.), chair of the Home Transportation Committee.
Isaacman has mentioned little about why he sought to steer the company or what he would do if confirmed by the Senate. “Having been lucky to see our superb planet from house, I’m keen about America main essentially the most unimaginable journey in human historical past,” he mentioned in a social media publish the day of Trump’s announcement.
In his restricted post-nomination feedback, he has emphasised the significance of U.S. management in house exploration. “I used to be born after the Moon landings; my kids had been born after the ultimate house shuttle launch,” the 41-year-old mentioned in his publish. “With the assist of President Trump, I can promise you this: We’ll by no means once more lose our potential to journey to the celebs and by no means accept second place.”
He returned to that subject in a hearth chat on the Spacepower Convention Dec. 11, whereas staying away from specifics about his nomination. “I do know we are able to’t be second,” he mentioned.
Trade consolidation and saving Hubble
Whereas neither Isaacman nor the incoming Trump administration have mentioned their plans for NASA, Isaacman has supplied hints within the type of a paper path of social media posts within the months earlier than Trump’s announcement.
One theme is dissatisfaction with the efficiency of many aerospace and protection prime contractors. He has steadily lamented what he referred to as the “extreme consolidation” amongst these corporations within the a long time because the finish of the Chilly Struggle, which he argued has made them much less environment friendly.
These posts typically centered on protection contracting — Isaacman, as a aspect enterprise to Shift4, co-founded and led for a number of years Draken Worldwide, a army plane coaching firm — however are additionally relevant to house. In October, he appeared to endorse a commentary by Michael Bloomberg that was sharply vital of NASA’s Artemis lunar exploration marketing campaign.
“There are authorities boondoggles, after which there’s NASA’s Artemis program,” Bloomberg wrote, criticizing the fee and effectiveness of NASA’s present structure of the Area Launch System, Orion and Gateway. “The following U.S. president ought to rethink this system in its entirety.”
“These factors will not be new, and I agree with most of them, but it surely’s nice to have somebody like Mike, with a loud voice, educating folks on matters they might not be as aware of,” Isaacman wrote in a publish about Bloomberg’s commentary. Isaacman praised SpaceX, Rocket Lab and different corporations for injecting new vitality into the business.
“The world wants extra corporations like these and fewer from the previous if we would like our youngsters to witness NASA astronauts and different astronauts engaging in nice issues on the Moon, Mars and past.”
Isaacman’s main interplay with NASA earlier than his nomination concerned a joint NASA-SpaceX research of servicing choices for the Hubble Area Telescope. NASA introduced the research, carried out below a Area Act Settlement, in September 2022, and Isaacman participated in a briefing to announce that research. On the time, he advised {that a} Crew Dragon mission to reboost and even restore Hubble is perhaps a part of his Polaris Program.
Isaacman grew to become one of the vital vocal advocates for a business servicing mission to Hubble, one which presumably he would command if it was a part of Polaris. After Hubble went into secure mode briefly in late 2023 due to an issue with one in every of its three gyroscopes, Isaacman made the case on social media for a Polaris servicing mission to Hubble. “A research was accomplished earlier this yr…this ought to be a straightforward danger/reward resolution,” he concluded. (NASA by no means launched that research or perhaps a abstract of it.)
However in June 2024, NASA determined to not pursue a servicing mission even after that defective gyro went offline completely. The company concluded that the danger of a “untimely lack of science” from Hubble if one thing went mistaken on such a mission outweighed any advantages from elevating Hubble’s orbit or making repairs.
“Had a mission been flown, and I used to be blissful to fund it, I consider it will have resulted within the improvement of capabilities useful to the way forward for business house and alongside the best way given Hubble a brand new lease on life,” Isaacman mentioned in a publish shortly earlier than NASA introduced it will not proceed with a business servicing mission.

Isaacman has additionally been an advocate for NASA’s Chandra X-Ray Observatory. NASA’s fiscal yr 2025 price range request proposed a steep reduce within the working price range for Chandra, one which astronomers argued would successfully shut down the 25-year-old house telescope. Isaacman was amongst those that leapt to Chandra’s protection.
“The untimely lack of Chandra will lead to a dying spiral for X-ray astronomy in america,” he wrote in an April letter to NASA Administrator Invoice Nelson, noting the comparatively small working price range for Chandra of about $70 million per yr. “It’s significantly disheartening to witness billions of taxpayer {dollars} funneled into the Area Launch System (SLS) and never one however two lunar touchdown contracts.”
Isaacman has mentioned little about different components of NASA’s science portfolio, although. On the annual assembly of the American Geophysical Union (AGU) in Washington every week after the nomination, an air of unease hung amongst scientists who had been unsure about what Isaacman would do and recalled efforts by the primary Trump administration to cancel a number of Earth science missions.
“We’re all conscious that we’re about to undergo a interval of change as we welcome the brand new administrator and new administration,” Nicola Fox, NASA affiliate administrator for science, advised an Earth science city corridor assembly on the AGU convention. That change, she acknowledged, could possibly be “tense” but additionally introduced a chance. “It doesn’t matter what change occurs, we’ll nonetheless stay totally centered on our mission.”
Ardour and expertise
Nonetheless, many within the house neighborhood welcomed the selection of Isaacman to steer the company, seeing him as a possible change agent for a way NASA does enterprise.
“You’ve obtained a person who has ardour, which is, I believe, a vital element,” mentioned Richard DalBello, outgoing director of the Workplace of Area Commerce, of Isaacman throughout a panel dialogue on the SpaceNews Icon Awards Dec. 6. “You might have somebody who has ardour, who has expertise operating a company, who’s himself a pilot and an astronaut, and I believe that’s an incredible mixture.”
On the identical panel, Tim Crain, senior vp of lunar infrastructure firm Intuitive Machines, mentioned he anticipated Isaacman to attract on his expertise within the non-public sector to refine how the company works with business.

“Commercialization is just not a binary occasion and it’s not even a transition. It’s a steady course of. We’re at all times making an attempt to judge the place is it proper for the federal government to proceed to do issues and the place can we hand issues over to the business sector,” Crain mentioned. He added he anticipated Isaacman and the brand new administration to judge “the place to push the federal government down a bit bit or have the federal government assist a bit bit extra.”
“At this vital time, as NASA and business house change into inextricably linked towards the success of our nation’s house program and our continued international management in house, I can not think about a greater candidate for this function,” mentioned Dave Cavossa, president of the Business Area Federation, an business commerce group.
Others in business, although, significantly among the many prime contractors that Isaacman has criticized, have been silent on the nomination. The identical is true for members of Congress, who’ve been quiet even whereas talking out for or in opposition to different Trump administration nominees.
The management of the Senate Commerce Committee did ship a message about the way forward for NASA in December with the introduction of a NASA authorization invoice. Put ahead too late to be thought-about by the Senate earlier than the tip of the 118th Congress, the invoice is as a substitute thought-about a sign of its priorities for the company and the place they may differ with the brand new administration.
That features a part of the invoice supporting NASA’s present method to Artemis. “As a part of the human exploration actions of the Administration, together with progress on Artemis missions and actions, the Administrator shall proceed improvement of house exploration components” recognized in earlier authorization payments, reminiscent of Orion and SLS, the invoice acknowledged.
One other part, titled “Reaffirmation of the Area Launch System,” directed NASA to offer a report on plans to make sure a flight price of two SLS autos a yr; NASA’s present plans embrace no a couple of SLS launch yearly.
“This bipartisan laws brings stability and certainty to NASA and your complete U.S. house program,” mentioned Sen. Ted Cruz (R-Texas) in an announcement. With Republicans within the majority within the Senate within the 119th Congress, he will probably be chair of the Senate Commerce Committee, which can maintain a affirmation listening to for Isaacman’s nomination.
A Capitol Hill supply, talking on background, didn’t anticipate Isaacman to run into severe issues along with his nomination, however anticipated that he must tackle his obvious criticism of Artemis in addition to his relationship with Elon Musk to assuage any considerations about conflicts of curiosity, significantly given Musk’s shut relationship with Trump.
Congress is essentially not aware of Isaacman, who has spent little time assembly with members on house matters. DalBello advised that Isaacman be paired with somebody who’s “a bit bit extra of an institutional individual” to assist lead the company. “However I believe this isn’t an administration that’s going to be involved about custom,” he added.
At a press convention the day after the nomination announcement, present NASA administrator Invoice Nelson mentioned he had spoken briefly with Isaacman, inviting him to a gathering. Nelson declined, although, to debate another particulars in regards to the name.
Nelson sounded unconcerned that Isaacman and the brand new Trump administration may make main modifications to Artemis regardless of criticism of the efforts and ongoing issues. NASA held the briefing to announce one other delay within the launch of the Artemis 2 mission, to not less than April 2026, after investigating sudden erosion of the Orion spacecraft’s warmth defend.
“I anticipate that that is going to proceed,” he mentioned of the present structure, saying he didn’t consider “that you just’re abruptly going to have Starship take over the whole lot.”
“I’m mainly optimistic in regards to the future for NASA below the brand new administration,” he concluded.
