Episode 42: Leroy Chiao on the perils of long-duration spaceflight

In this wide-ranging conversation, astronaut Leroy Chiao joins Miles to talk candidly about what it’s really like to live and work in space — and inside NASA. From Cold War suspicion to Russian cooperation, and from toilet paper certification to Starliner delays, it’s a journey full of humor, frustration, and hard-earned insight. Chiao also shares why he almost flew a year-long mission (spoiler: a very large space tourist), what happens when blood flows the wrong way in microgravity, and whether Jared Isaacman can actually fix what’s broken at NASA.
