Lesson time 11:33 min

In his parting words, Chris reflects on the cyclical nature of human exploration and Earth’s place in outer space.

Teaches Space Exploration
The former commander of the International Space Station teaches you the science of space exploration and what the future holds.
Get Started


Exploration is our history. It's the legacy that got us to where we are, and it's always been that way. We live someplace for a while, and then either the conditions are good enough or desperate enough that some of us leave and go somewhere else and explore. And once we've explored a bunch of places, then we say, you know what? Some of us are going to go from here to that place, because it looked interesting. It looked worth going to. And we start settling somewhere else. And we've been doing that for thousands and thousands of years all around the planet. I think our latest guess is the native peoples of Australia got there like 70,000 years ago. But some parts of the world we've just very recently got to. The very first human beings only got to New Zealand like 750 or 800 years ago. No human had gotten that far. That's not very many generations. The first of us to get to Antarctica-- that was only really one long human lifetime ago, just a little over 100 years ago. And we've only been going to space for just a little over 50 years. The pattern has always been explore, understand, choose, and then maybe go and settle sometime later. And we've been exploring space for most of my lifetime. We've been looking around, seeing. We've even sent probes beyond Pluto now-- right outside our solar system, in fact, with Voyager. But we decided about 30 years ago that the place we should settle first in space is orbiting the world. We should build a permanent habitation as a species-- not just one country, but as a lot of leading nations in the world. Let's colonize space, and we built the International Space Station. And starting in the fall of 2000, we started permanently living off the Earth. We went through that exact same pattern of exploring, thinking, choosing, and then starting to settle in a new place. And we will go from the space station where we're testing equipment right now that keeps us safer eventually to the moon-- the moon, I think, pretty soon. And then from the moon, we'll have learned enough things and tested. And just like all our forebearers did, we can go further. We can go as far as Mars. We have a lot of stuff to learn. We have to invent stuff we haven't even realized we need to invent yet, but I'm not impatient. I'm delighted. We're doing stuff that was impossible when I was a kid that no human had ever done. We have six of us permanently living off the planet right now, and we sort of take that for granted. It's good that we're impatient. It helps drive us to do things we've never done before. I think it's just a continuation of the fact that we are explorers, and our technology is just good enough now that we can be space explorers. I sure can't speak for everybody else. In my particular limited view of the world, you get given one set of capabilities-- this body, this brain, this particular combination of capabilities to do things. And to squander it-- to not do what you're capable of doing, to no...

Explore the unknown

Impossible things happen. At age nine, Chris Hadfield knew he wanted to go to space. He eventually went there three times, becoming a commander of the International Space Station. In his MasterClass, Chris teaches you what it takes to explore space and what the future holds for humans in the final frontier. Learn about the science of space travel, life as an astronaut, and how flying in space will forever change the way you think about living on Earth.


Students give MasterClass an average rating of 4.7 out of 5 stars.

Wow, Chris is an outstanding speaker and professor!

This is absolutely a masterpiece. Thank you Chris for having shared your unique knowledge and your unique life journey.

Inspirational, amazing, my favorite class to date.

That was simply the most concise and gathered perspective on human endeavour I've had the pleasure of watching Heartfelt Thanks T



I really loved listening to Chris Hadfield. He is a source of inspiration and motivation to be the better version of myself. I would have liked to go deeper in the «technical» learnings but I finish this class with some great tools. Thank you

Thanks a lot sir. Its been a pleasure watching your masterclass. I look forward to seeing more of it.

Thanks a lot for the way you developed the whole classes, those the most amazing stories, details and experiences I heard in a long time. I imagined with you words how disciplined you must be as an astronaut. Please, let me invite you to Colombia, lovers of the sky will love to meet you face to face, for sure you will touch so many minds to encourage them with the space exploration and science just with your details stories. Very good teacher, this is my best master.

I loved this Masterclass. Chris Hadfield gave so much of himself throughout every lesson, which was a lesson in and of itself. Curious about space exploration I took this class expecting to gain some general knowledge, however, I gained insight into a mindset that can be applied to any profession or problem.

Thank you so much for sharing what must be a really unique and surreal experience. I think Earth and its crew would be healthier and more at peace if everyone could go to space and look back over their shoulder, if only for a minute. This masterclass is for most of us the closest we'll ever get to experiencing that emotion and those feelings. Congratulations and long live space exploration!

Thanks a lot Chris, I have learned a lot and all the lessons were excellent and served as a review for me on some of the topics. I have enrolled at the League of new Worlds - Astronautics course but sadly i did not finish the course because of my very busy schedules as a Physician, My studies on the "Science Behind Living in Mars" from the Monash University in Australia was a very delightful course and maybe someday we definitely explore Mars and beyond . I believe we can overcome all the difficulties espcially on the technologies involve but we dont have to stop inventing discovering new things to reach that goal. My Astrobiology class which i just completed is very much challenging, I really do not believe we are alone in this vast Universe, in fact I believe even in a multiverse. It is nice to follow you again in some courses in the future. Thanks , it is a great honor to met you on -line and God Bless...

I learned so much and I am a space buff......but this took information detail to a new level. Loved it. Totally enjoyed Chris’ book. He is one of the most articulate astronauts and certainly the best at explaining the experience to lay persons. All elementary and high school students should have the opportunity to have this lesson.

Amazing closing statement Chris! Thank you for sharing your experience! Loved this course!


Please add more STEM lessons. This was an amazing course, and why I signed up. Thank you for providing this service! I signed up not to become an astronaut or musician, but to understand other careers. Fascinating.

I loved every minutes of this masterclass and I would enjoy and listen carefully at any argument explained from him. Such an inspiration and I’m glad For this course! Hoping for the second part! Thank tou
