Joe Rogan welcomes Garrett Reisman, a former astronaut who spent 95 days in space. Reisman shares his experience of wanting to stay in space for 100 days to earn a patch, but he was brought back early. He discusses the physical effects of returning from space, including balance issues and muscle atrophy, and explains how countermeasures like resistive exercise have improved since his time in space. Reisman describes the unique experience of sweating in space, where sweat forms a film on the skin instead of dripping. He also talks about the daily workout routine astronauts follow to combat muscle and bone loss. The conversation shifts to the challenges of returning to Earth, including the vestibular system's adjustment and the potential for "space brain," a term for short-term memory issues experienced by some astronauts. They discuss the long-term effects of living in microgravity, including the body’s adaptation and the potential for humans to evolve differently in space. Reisman mentions the science fiction series "The Expanse" as a portrayal of how humans might adapt to life in low gravity. Rogan and Reisman talk about the food astronauts eat, which consists mainly of freeze-dried meals, and the challenges of bringing fresh food into space. Reisman recalls his first view of Earth from space, which he found underwhelming compared to his expectations. He describes the "overview effect," where astronauts realize the interconnectedness of humanity when viewing Earth from space. The discussion includes the addition of the cupola module to the International Space Station, which provides stunning views of Earth. Reisman shares his experiences with spacewalks and the challenges of working in a bulky spacesuit. He recounts a memorable moment when he had to solve a problem with a connector during a spacewalk. Reisman reflects on his transition from NASA to SpaceX, where he worked on various projects, including the Crew Dragon spacecraft. He discusses the importance of public-private partnerships in space exploration and the advancements in technology that have come from this collaboration. They touch on the issue of space debris and the potential dangers it poses to spacecraft. Reisman explains the challenges of cleaning up space junk and the need for better practices to prevent further pollution of Earth's orbit. The conversation shifts to the future of space travel, including the potential for colonizing Mars and the technological advancements needed to make it a reality. Reisman emphasizes the importance of finding solutions to environmental problems on Earth while also preparing for humanity's future in space. Finally, they discuss Reisman's involvement in the Apple TV series "For All Mankind," where he serves as a technical consultant, helping to ensure the show's accuracy in depicting NASA's history and the challenges of space exploration.

Joe Rogan: Welcome to the Joe Rogan Experience. Today, we have Terry Virts, who spent 200 days in space. Terry Virts: Thanks for having me! My first flight was two weeks, and after that, I wanted more. The two-week flight was incredible, but after 200 days, I felt like I had checked all the boxes. I was a shuttle pilot, station commander, and even made an IMAX movie while up there. Joe Rogan: What was the recovery like after two weeks? Terry Virts: There is a recovery period. I felt dizzy and heavy when I landed. The first day was tough, but after a week, I was back to about 90%. They have you exercise in space to combat bone density loss, which is about 1.5% per month. I exercised religiously, using a weightlifting machine and treadmill. Joe Rogan: Do you sweat in space? Terry Virts: Yes, when you exercise, you sweat a lot. But normally, you don’t notice it. I did an experiment with merino wool clothing, and it didn’t stink after a month of wearing it, which was surprising. Joe Rogan: What kind of exercise do you do in space? Terry Virts: We have a resistive exercise device that uses vacuum to create resistance. It’s important for maintaining muscle and bone density. I did it every day except for spacewalk days. Joe Rogan: What’s the recovery like after a long mission? Terry Virts: After a week, I was doing well. They monitor your balance, and I actually scored better after my flight than before. They don’t want you driving for a couple of weeks after landing. Joe Rogan: What do you eat in space? Terry Virts: The food is like MREs, and I actually liked it. The Russian food was great too. We had a system for sharing food we didn’t like. Joe Rogan: How was your experience with learning Russian? Terry Virts: I learned some, but it’s a tough language. I can have conversations, but I’m not fluent. Joe Rogan: What was your background before becoming an astronaut? Terry Virts: I was a test pilot and flew jets. I was inspired by Chuck Yeager and the book "The Right Stuff." Joe Rogan: What’s your perspective on the future of space travel? Terry Virts: I’m optimistic. Private companies are pushing innovation, and we need to keep exploring. Joe Rogan: What’s the deal with space debris? Terry Virts: It’s a huge problem. We need to manage it better. If we don’t, it could make space travel impossible in the future. Joe Rogan: Do you think we’ll colonize other planets? Terry Virts: It’s possible, but we need to figure out the technology and the politics first. Joe Rogan: What’s your take on extraterrestrial life? Terry Virts: There are likely other life forms out there, but the distances are vast. We might never know for sure. Joe Rogan: What’s your book about? Terry Virts: "How to Astronaut" shares my experiences and insights from space travel, aimed at a general audience. Joe Rogan: Where can people find you online? Terry Virts: You can find me on Instagram as Astro Terry. Joe Rogan: Thanks for coming on, Terry. It was a pleasure. Terry Virts: Thanks for having me!
