Finally, we launch into Musk’s ultimate quest — his desire to colonize Mars — and how he went from wanting to save earth to wanting to escape it. We hear the origin story of SpaceX, including why one astrophysicist calls Musk’s Earth-exiting plan “delusional.” Is the red planet the ultimate “bubble” of total control, or does it represent a level of hubris that’s out-of-this-world?
Guests in this episode include:
- Robert Zubrin, aerospace engineer and Mars-exploration advocate
- Tom Moline, former SpaceX employee and co-signer of an open letter against Musk’s antics
- Adam Becker, journalist with a background in Astrophysics, Mars mission skeptic
Topics in this episode include:
- How Mars Society advocates courted Elon Musk in his PayPal days, but soon went from patron to self-appointed messiah of the movement
- The origin and history of SpaceX, its “toxic” and loudest-voice-wins culture, and its plans to colonize Mars and turn humanity into a “multi-planetary species”
- The ethics and feasibility of space colonization, Elon’s open fascination with Sci-fi and fantasy — especially utopian ideas and Isaac Asimov’s book Foundation
- The very real challenges of colonizing Mars, from poison dirt to high radiation to the unpredictable impacts on human biology, fertility and psychology
- Planet B and the idea of Mars as the ultimate, engineered “bubble” — and why even optimists like Zubrin are troubled by the scope of Musk’s promises, calling them “bat guano crazy.”
