Billionaire Jared Isaacman talks space walk, Elon Musk at Lehigh University
BETHLEHEM, Pa. — Entrepreneur and commercial astronaut Jared Isaacman told a Lehigh University audience that space exploration stands at a transformative moment, with dramatically falling launch costs poised to unlock new opportunities for humanity.
Speaking to students and faculty on Tuesday, Isaacman, who led the Inspiration4 and Polaris Dawn missions, emphasized that the space industry has reached “the healthiest time we have ever had” with multiple companies launching rockets regularly and driving down costs through competition.
“SpaceX is launching every two days,” Isaacman said, noting companies including Blue Origin, Rocket Lab and others are creating unprecedented access to space. “We have no other time in the history of human spaceflight where we can just rattle off so many names of companies that are building rockets.”
The Lehigh Valley resident and Shift4 Payments founder, who started the payment processing company at 16 in his parents’ basement, said establishing a true space economy remains essential for progress beyond taxpayer-funded missions.
He pointed to potential opportunities in mining helium-3 on the moon and extracting minerals from asteroids.
“We need to figure out what, why we need space,” he said. “We can’t have this exciting future in space being entirely funded by taxpayers.”
Isaacman’s Inspiration4 mission in 2021 raised $250 million for St. Jude Children’s Research Hospital, including a $50 million contribution from SpaceX CEO Elon Musk after splashdown.
The four-person civilian crew included Hayley Arceneaux, a childhood cancer survivor and St. Jude physician assistant who became the youngest American to orbit Earth.
For students interested in aerospace careers, Isaacman recommended coupling engineering studies with artificial intelligence, predicting that AI will be essential for analyzing sensor data and enabling deep space missions where communication delays make Earth-based mission control impractical.
“This is absolutely the best time for it,” he told students considering space careers, noting that SpaceX’s Starship has more habitable volume than the International Space Station.
Addressing the role of NASA alongside commercial companies, Isaacman argued that the space agency should focus on breakthrough technologies like nuclear propulsion, while the industry handles proven capabilities.
He cited the need for nuclear power to produce fuel on Mars for return trips and to enable efficient travel between destinations.
“NASA needs to work on why we all contribute as taxpayers on the near impossible,” he said. “What no business could ever underwrite a business model against.”
The talk came months after Trump withdrew Isaacman’s nomination to lead NASA. He acknowledged being “a failed NASA nominee” but maintained his vision for expanding academic institutions’ involvement in space science missions.
Isaacman reflected on seeing his crewmates pursue their passions during the Inspiration4 mission — Dr. Sian “Leo” Proctor painting and writing poetry, Arceneaux photographing herself beside Earth, and Christopher Sembroski playing ukulele.
“It was kind of all those human moments that came together that made us a crew,” he said.
Lehigh recently launched a master’s program in aerospace and space systems engineering. Faculty members have conducted experiments on the International Space Station, studying particle movement in zero gravity.
Isaacman urged aspiring space entrepreneurs lacking capital to first work for established companies, learn the industry and build resources before striking out independently.
“If you’ve identified the kind of general sector you want to be in, you work really hard, get into a company that you would be happy working at that you could learn from,” he advised.
