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. \r\n\r\nThis 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.
