In this uncut conversation we discuss:
• Why the “hardest part of Mars” isn’t rocket science—it’s political science
• The real odds of dying on launch (and why astronauts still get on the rocket)
• What daily life on the ISS actually feels like: schedules, sleep, food, and isolation
• The weirdest realities of microgravity (yes…including the toilet)
• The twin study surprises: telomeres, time dilation, and what space does to your biology
