with Jeff Thornburg
Neil deGrasse Tyson and Chuck Nice interview aerospace engineer and Portal Space Systems CEO Jeff Thornburg about the emerging space industry, agile spacecraft propulsion, and the interplay between government and commercial space. Thornburg discusses his work on advanced rocket engines at the Air Force Research Lab and SpaceX, why rapid maneuverability in orbit is now strategically critical, and how his company is pursuing solar-thermal propulsion and modular spacecraft. They also examine the value of failure in engineering, the consequences of cutting U.S. R&D and NASA science budgets, the geopolitical competition in space-especially with China-and speculative future technologies like quantum-enabled warp-like drives.

Actionable insights and wisdom you can apply to your business, career, and personal life.
In complex engineering and innovation, embracing controlled failure and rapid iteration is more effective than striving for zero risk, which drives costs and timelines to unsustainable extremes.
Reflection Questions:
Rigorous, transparent risk management-where leaders explicitly accept and document risks rather than ignore engineering concerns-builds resilience and accountability when things go wrong.
Reflection Questions:
Public and private sectors play different but complementary roles: markets pursue near-term value, while governments must invest in foundational, high-risk R&D that has no immediate business case but underpins future breakthroughs.
Reflection Questions:
Integrity in innovation-being honest about progress and limits instead of selling "vaporware"-builds durable trust with partners, customers, and investors, even if it slows short-term hype.
Reflection Questions:
Engineers and builders do their best work with clear constraints and well-defined problems; vague ambitions without boundaries paralyze creativity instead of enabling it.
