The Race for the Next Generation of Rockets, with Jeff Thornburg

What will the future of space look like? Neil deGrasse Tyson and comic co-host Chuck Nice explore the engineering challenges and scientific questions shaping the next era of aerospace with aerospace engineer and CEO of Portal Space Systems, Jeff Thornburg.

From the Mars missions to the development of reliable, reusable rockets, we ask: how do we build spacecraft that are fast, safe, and simple enough to transform space into a true commercial frontier? We discuss the balancing act between government funding and private investment: why do we still need public dollars to seed technologies that don’t yet have a business case?

Why is “failure” embraced by startups but avoided in legacy programs? And what lessons can be learned from disasters like Hubble’s flawed mirrors or the Mars Climate Orbiter’s metric–imperial mix-up?

We explore reusable rockets, the tradeoff between fuel and payload, and the art of designing systems around unknowns. We also discuss the U.S.’s international competition in space and whether we can keep up. Why should citizens care about defending satellites, and what would it mean if GPS orbits were compromised?

What propulsion breakthroughs could quantum physics unlock? Could solar-thermal engines or nuclear concepts make space travel faster and more sustainable? We discuss our dreams for the space industry. Will we ever achieve suborbital flights around Earth in 45 minutes, or treat the Moon as just another backyard destination?
