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.

What an incredible class. So much more than just space or being an astronaut, Chris shares how to pursue your dreams and become the person you want to

Very insightful into space exploration and the mechanics. Chris is a great speaker and with great experiences. Never gonna get this any where online!

Iinspiring teacher, this class motivates self improvemet, a lot of interesting infomration about a lot of fields of science.

This guy is simply awesome! also a great idea to include something more scientific in the classes. Absolutely recommendable!!

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

So incredibly inspiring! Best class ever with wisdom for every path of life. Thank you so much for your contribution. Two emotional moments stand out for me: the dock story, and the description of leaving the hatch and being suddenly present in the universe. This course could make the world a better place.

Can an object just sit in space and not move? Would there be a use to having relay satellites?

I loved taking this course, very interesting, you brought me back to my childhood. I dare to dream. Keep going Chris

Herbie Hancock's class is wonderful. Both Herzog's and Scorsese's classes are terrific. R.L. Stine's class is essential if you're writing stories for kids. But, having said that, Chris Hadfield's class has been my favorite, for all of the good reasons already mentioned by others here. A+.
