DJ White, Greenpeace co-founder and marine conservationist, and Tom Murphy, physicist/astronomer and author, debate space colonization fantasies. They dismantle asteroid mining and Mars myths with physics and ecology. They explore cultural reasons for space obsession, physiological and engineering impossibilities of living off Earth, and urge refocusing energy on protecting the planetary home we're already on.

Episode notes
Asteroid Mining Is Economically Impossible
- Space mining and off-world resource plans ignore the rocket equation and energetic costs, making them economically and physically impractical.
- Tom Murphy and DJ White note OSIRIS‑REx dirt returned at ~$132,000 per ounce and argue adding asteroid supply would crash any mineral market.
Space Fantasies Work As Tech Religion
- Space optimism functions as a tech religion and psychological escape from confronting biophysical limits and the carbon pulse.
- DJ White and Tom call it magical thinking fueled by narratives of limitless human ingenuity and evolution metaphors.
Human Space Missions Are Stunts Not Settlements
- Human missions (Moon, Mars) are orders of magnitude harder and costlier than robotic missions, and long-term living off‑Earth hasn't been demonstrated.
- Tom cites Apollo as a stunt, ISS costs ~ $1M per astronaut‑day, and Mars would be ~600× the Moon's distance and physiologically brutal.
