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.

Excellent mid-career reminder to follow one's dreams

Chris Hadfield is one of the best and the most enthusiastic teacher ever.

Inspirational, amazing, my favorite class to date.

Chris makes you feel like you are about to launch into space! Great educational class!

Been dreaming about being an astronaut since the age of 7, so this is just awe-inspiring to me! Planning to go to Air Force Academy, become a test pilot and than hopefully get accepted into the NASA Astronaut Candidate Program! If anyone has tips or just anything please contact me! or 928-821-5430. Thank Chris Hadfield, this was one of the most inspiring things I've ever seen!

Does anyone know what the introduction music is for this video that starts around 00:12? Thank you!


Watched this with my 11 year old son and we are thoroughly enjoying this series. With this Master Class, he is learning so many new things in preparation for his second tour of Space Camp this summer, which corresponds with the 50th Anniversary of the first Apollo moon landing. I think Chris does a great job of describing what it takes, what to expect, and how to prepare to be an astronaut. Great content for a young future astronaut, or an older adult who missed their calling! :)

Love how he connected ones personal exploration to the exploration of reality. Quite poetic and powerful. Learned something about myself already. Excited to start this class.


Disgraceful that a fraud gets to promote lies on a pay for knowledge site. I demand money back when it only buys lies.

Hey Chris, I would love to be a future astronaut and fly the Soyuz FG rocket to the space station, I would like to be a botanist on the space station, any advice?

I can't wait to do this. I need to know what it's like. So, I can tell my 12 year old self.
