Date: 2013-11-11 | Duration: 1h 4m

Episode Overview

Commander Chris Hadfield shares a fascinating look into life in space and the challenges astronauts face, starting with the profound physical changes the body undergoes in microgravity. He describes how astronauts lose calluses on their feet and develop new ones on the tops of their feet due to floating rather than walking, and explains the rigorous daily exercise routines necessary to maintain cardiovascular and muscular health. Hadfield also delves into the psychological demands of long-duration space missions, emphasizing the importance of mental resilience and how astronauts prepare to cope with isolation and confinement, especially on future missions to the Moon and Mars. The conversation shifts to the technical and scientific marvels of space exploration, including the complexities of landing on Mars, where the atmosphere is too thin for parachutes but too thick to ignore, requiring innovative landing systems. Hadfield reflects on the awe-inspiring images sent back by rovers and the tantalizing possibility of past or present life on Mars, highlighting the ongoing quest to understand our place in the universe. He also touches on the mysteries of dark matter and dark energy, expressing humility about humanity’s limited knowledge despite technological advances. Throughout, Hadfield’s stories and insights offer a unique perspective on the intersection of human endurance, scientific discovery, and the vastness of space.

Starting point is 00:00:00 His name is Chris Hatfield. The book is An Astronaut's Guide to Life on Earth. Starting point is 00:00:31 all the details, but to try and link in life on earth with, uh, with seeing that spotlight go Starting point is 00:01:09 So your whole cardiovascular system changes. Starting point is 00:01:39 And most of them you feel, I mean, you lose the calluses on the bottom of your feet. It's kind of disgusting because your feet are like a snake up there, but the bottom of your feet are shedding because you never use the bottom of your feet. And you build up calluses on the top because you're Starting point is 00:02:12 blood out of my feet and pump it properly back up to my head. Starting point is 00:02:49 And your body, we don't even know why. We don't know what sensors in the body Starting point is 00:03:30 The rest of my body was fine. Starting point is 00:03:55 We do one hour of cardiovascular and one hour of resistive every single day, seven days a week for Starting point is 00:04:25 so that every time you bend your elbow or twist your body or something, Starting point is 00:05:02 This is one of the problems we need to solve. Starting point is 00:05:25 even to go to the moon, as far as habitation goes. Starting point is 00:05:43 Then I think we'll go to the moon, because it's the next, it's only three days away. And then we can do Starting point is 00:06:08 Psychological. How do you keep people sane? Starting point is 00:06:38 and that, those people will become Martians in their mind. Starting point is 00:07:05 I heard those words come out of her mouth. And it was like, she has in her mind completely Starting point is 00:07:39 because as you say, once you get the engines going fast enough that you're headed for Mars, you can't just turn around. Starting point is 00:08:12 And what about, like, sustainable resources, like as far as, like, food and things like that? Starting point is 00:08:48 I mean, the topsoil is full of water on Mars.
