The Engineer's Journey: Spaceflight and STEM with Lehigh University Professor Terry Hart

Send us Fan MailIn this episode of Mind Over Molecules, I sit down with Professor Terry J. Hart—a former United States Air Force pilot, NASA astronaut, and current professor of mechanical engineering at Lehigh University—for a conversation about exploration, engineering, and the future of humanity in space. Selected by NASA in 1978, Professor Hart flew aboard the Space Shuttle Challenger during mission STS-41C, where he helped deploy and repair satellites in orbit during one of the most ambitious eras of human spaceflight. Beyond his work in orbit, he has spent decades contributing to engineering education and innovation. He mentors the next generation of scientists and engineers both through his Lehigh University courses and his TikTok account, @ihartaerospace. In this episode, we discuss his journey from engineering student to astronaut, the mindset required to work in high-pressure aerospace environments, and his perspectives on leadership, teamwork, and resilience in STEM. We also dive into the Artemis II mission and what humanity’s return to deep-space exploration means for the future. Most importantly, we reflect on the Challenger disaster and the lessons it continues to teach us about engineering ethics, organizational culture, communication, and the human cost of exploration. Professor Hart shares thoughtful insights on risk, innovation, and what young engineers and scientists must understand as they shape the future of technology and discovery!!
