The Space Revolution with Rick Tumlinson

In this thought-provoking episode of The Space Revolution, host Rick Tumlinson sits down with space architect and strategist Brent Sherwood to challenge some of the biggest assumptions in space exploration. From NASA and Artemis to Mars, the Moon, commercial space stations, and the future space economy, Brent introduces his “Four Futures” framework—a way of thinking that separates exploration, settlement, tourism, and space-based industry into distinct paths instead of treating them as the same goal. Along the way, the conversation explores why returning to the Moon may be more important than racing to Mars, why near-Earth asteroids deserve far more attention, and what humanity still doesn’t know about living—and eventually thriving—beyond Earth. In the second half of the conversation, Brent shares his remarkable journey from aspiring architect to Boeing, NASA’s Jet Propulsion Laboratory, and Blue Origin, along with the mentors and experiences that shaped his vision for humanity’s future in space. Whether you’re a lifelong space enthusiast or simply curious about where humanity is headed next, this episode offers a fascinating look at the big-picture thinking behind our next giant leaps. Topics include: Brent Sherwood’s Four Futures model Why exploration and settlement are not the same thing The case for returning to the Moon before Mars Near-Earth asteroids and the future of space resources Closed ecological life support and living sustainably in space Commercial space stations and the emerging space economy Brent’s career at Boeing, JPL, and Blue Origin The mentors who influenced modern space development See more at https://www.aureliainstitute.org/brent-sherwood If you enjoy thoughtful conversations about the people, ideas, and movements shaping the next chapter of human exploration, subscribe to The Space Revolution and join us each week for conversations with the pioneers, entrepreneurs, scientists, artists, and visionaries building humanity’s future in space.   Don't miss The Space Revolution on iRoc Space Radio!   Listen live on iHeart Radio Mondays & Thursdays 8AM & 8PM PST The Space Revolution podcast is produced and distributed exclusively by iRoc Space Radio Your Go To Place in the Galaxy for Space News, Culture, Entertainment and Music.

Have we been thinking about humanity’s future in space all wrong? What if the technologies that carry us beyond Earth are only half the story—and the real challenge is who we become along the way? In this episode of The Space Revolution, Rick Tumlinson welcomes Samantha Tauber (VNCCII)—Creative Polymath, Space Diplomat, and author of Made in Energy, the first novel in her VNCII trilogy—for a wide-ranging conversation about the role of creativity, storytelling, and human consciousness in building humanity’s future beyond Earth. Together, they explore why artists belong alongside engineers, why space exploration should inspire us to look inward as much as outward, and how culture, imagination, and authenticity may become some of humanity’s greatest assets as we expand into the cosmos. You’ll hear them discuss: Why humanity doesn’t have to become perfect before becoming a multi-planetary civilization The relationship between space exploration, personal growth, and the Overview Effect How storytelling and science fiction inspire the future long before technology catches up Samantha’s vision for space diplomacy and using creativity to unite people across cultures The inspiration behind Made in Energy, the first book in her VNCII trilogy, and her long-term creative vision Why independent creators and artists have an essential role in shaping humanity’s future in space Why finding your authentic voice may be one of the greatest contributions you can make—to Earth and beyond Whether you’re passionate about commercial space, science fiction, the Overview Effect, human potential, or the future of civilization, this conversation offers a fresh perspective on what it truly means to build humanity’s future beyond Earth.
