Chris Hadfield
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


If you were born 120 years ago, the idea that we could fly wasn't part of normal society. Through the combination of a real sense of purpose and an enormous amount of work on behalf of a lot of people, we can make impossible things happen. It gives me heart, gives me courage, gives me joy, and gives me hope. And I think exploration of the unknown, whether it's the unknown of the universe around us or just the unknown that's within each one of us. We can all use that personal exploration. We can all work that into the reality of life and be joyful as a result of the hope of exploring the unknown. This class is for anyone who is interested in exploration. And not just exploring space, like that's the obvious core of it, being an astronaut. But you'll learn a lot of things, along the way to space, about yourself, about how to turn yourself into somebody different than you used to be. It definitely is required, that type of thought process, to fly in space. But I'm really teaching this class to anyone who's interested in exploring a new idea, in exploring a new place, in exploring the things that you might be capable of. I'm Chris Hadfield, and this is my MasterClass.

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.

I have read Chris Hadfield's book before taking this course, I was pleased that it wasn't simply the same information repackaged, and the amount of insight and information he gives us in these videos is amazing.

that achieving impossible goals and dreams is actually not that impossible

My favorite class to date. Inspirational, educational, and thought provoking. Chris Hadfield is super impressive!

There will come a time when writing ‘speechless’ when completing a Masterclass will seem meaningless. But not today. This left me speechless. Amazed.

I have been looking at this course for such a long time. Having a degree for Astrophysics. This is up my all

I love space and only 13, Im looking for a future career with NASA potentially and figured this would quench my thirst for knowledge on my future and my interest for space exploration. Thanks Chris for giving me the opportunity!

Victoria C.

I loved that he talked briefly about leadership and the psychology of being in an intense environment while also needing to maintain a stable and calm mind.


I like the one-hand holding of the Nikon with the long, honking, telephoto lens on it. Only gravity could allow that one hand holding. LOL! Do you guys exclusively use Nikon D850s, D810s for space?

I'm in no way an expert on this, or even that knowledgeable in this domain seeing as how I'm 14 y/o, but I really adore space and its mysteries and I really think this will help me on my journey to learn so thank you Chris


I really enjoyed this course. Lesson 22 and the bonus session were my two favorite. Chris brings joy and excitement to the course. I loved his enthusiastic approach to the course. I could almost envision myself in the space shuttle along side of him during blast off. He is a great teacher. I loved this course

Raymond F.

I enjoyed this lesson very much. I feel I can have a detailed, thorough debate and conversation about the many different aspects of space travel after this extensive lesson. Listening to Mr Hadfield speak about his unique experiences and his methods for success have resonated deeply within me. I hope to be a fraction as successful and fearless as this gentleman. I salute you Commander Hadfield.

I've read Chirs Hadfield's book, An Astronaut's Guide to Life on Earth, and that got me very interested in his life wand work field. I am very excited to take this class!
