We can learn a lot by exploring the edges of the biosphere, where conditions can just barely support even the most hardy organisms. And by venturing beyond the biosphere– by leaving Earth and traveling into space– we can really test the limits of what our bodies are capable of. 

Scott Parazynski is a former NASA astronaut who has flown on five missions to space and completed seven spacewalks. He is also an emergency medical doctor who has climbed some of the highest mountains on Earth, including Everest, a scuba diver, pilot, rock climber, and luge athlete. 

Scott describes what it’s like to live and work in space, his journey toward becoming an astronaut, and what being in space and other extreme environments has taught him about Earth and about the limits of the human body.
