Chris teaches you the principles behind simulation setup, the mindset you need to learn as much as possible from simulations, and how astronauts prepare for worst-case scenarios.

Topics include: "Simulators Are Wrong • Simulate the Worst-Case Scenario • Visualize and Prepare for Failure • Emergency Training Across Agencies • Future Simulations"

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.

Learn about the past, present, and future of space exploration with astronaut Chris Hadfield.

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

Space travel is more complex than I realized.

This is a great class! I had an amazing time watching each lesson.

Chris Hadfield brought a revolution in the Field of Space. There is no other course in the universe that shed light on "How to Become an Astronaut"

This MasterClass is Excellent!! My Father-in-Law & I were on an Air Canada flight from Toronto to Calgary and saw Chris as we were traveling from First Class to Economy. My Father-in-law shook Chris' hand...I was too star struck. These videos are the equivalent of that hand shake. I was an Air Cadet for 4 years of my life. You have taught me so much. God Speed Chris Hadfield!

It's a shame we only die once, it would be a great learning experience. Contingency simulators are vital for spaceflight success.

Can you imagine if we could run kids/ everyone through various “ life” simulators in high school? We would all be much more prepared for life. Chris Hadfield is so correct: training and preparation not only alleviate’s fear, it makes you more confident and you enjoy the “ ride” because you know what’s coming.........maybe. Fantastic job, I watch this every spare minute I have, like a book you cannot put down. Hans Juergensen

Great!!!!! This is the most enjoyable course and beautifully presented by Hadfield. Thank you!

Interesting reflections about the benefits of preparing through practice, and simulation when real practice is not possible. It was nice also to know about international differences and collaboration. Nevertheless, It would have been great to experience what is being told, using videos or any other resource available through the web.

Prepare, prepare, and prepare some more. Who plans the sequence of simulations? I suppose there is learning on that end to be sure all contingencies are covered in the astronauts' learning. The contingency of the death of an astronaut must be the toughest. I liked the old school (eyes and watch) solution to closure rates and alignment. So much to wonder about and, once again, Cmdr Hadfield's story-telling is an art in and of itself. That is giving us a simulation of sorts...very vivid :)

Everything in this class has been amazingly interesting, but, to me, the most fascinating—& most useful/applicable—thing by far is the anecdote about connecting the docking adaptor/tunnel w/the Mir in the "Visualize and Prepare for Failure" subchapter. As the saying goes, amateurs practice until they get it right, but professionals practice until they can't get it wrong.

The contingency sim in your life is useful and practical advise. This episode gave me a sense of why he would make a great commander. Nerves of steel, courage under pressure, faultless precision, stamina, solid problem solving, and decision making. The Right Stuff. I love this guy. Please adopt me.

I'd love to try virtual reality and get the feeling of what it's like. I never thought that was even an option. Reality is an amazing sense of urgency and practice. I think it's wonderful the countries work together and offer different simulators. It's good news to know that we can get along. Contingency simulators sounds tough but so necessary right down to your family's involvement. Leave no stone un turned. This class is very thorough.

Though today's training facilities look seemingly advanced, the training simulations for the first Mars-bound astronauts, I guess is an important area all capable space agencies should look into.

at 11:45 Through simulations, it seems the simplest most critical result was brought into focus, dock without incident, in the dark (without power, without guidance) if necessary. Knowing the distance and the speed at that stage, whether calculated and automated or, if docking manually being able to observe and understand the calculations results in motion - knowing what that speed and direction about or exactly looks like, helps prevent collision of parts in space. survival oriented.

Simulation is not just important. It's critical to success. Think about how you learned to ride a bicycle. Someone took the handlebars and showed you how they turn. They showed you how the pedals turn, or showed you how the wheels turn. You did sort of a background study of a bicycle. And then someone put you on a bicycle, but made sure that you couldn't fall. That was really a bicycle simulator. They were giving you a simulation of what it was going to be like to ride a bike, but without the consequence of failure. A safe set of circumstances to practice your technique. And you turned the handlebars the wrong way many times, and you started leaning. Or maybe they stuck training wheels. On it was a bicycle without pedals you could work on one skill at a time. But eventually, through incremental simulation you gained the skill. So for that very first time you could launch. And you could get on the bike and start pedaling, and you were away. And now you could do something that you couldn't do before. It was because of a training program and simulation. That you could do that thing. That you could ride that bike. And a spaceship is really just a super complicated bicycle. We go through exactly the same process. And you train on your own with a steadily more complex integrated environment in the simulator, until finally you've gotten to a level of comfort and understanding that now other crew members can get into the cockpit with you. And then you start with a perfect flight. You launch and everything behaves itself. And you learn what it's really going to look and sound like. And then the instructors can start injecting failures, and failing one system that you have to deal with. And then you're watching as your system is failing, then on the other side there's some other system failing, and someone has to realize that those two systems actually affect each other. And it becomes steadily more and more complex. And what your training team is hoping, the people that are trying to get you ready for spaceflight. They're hoping to show you every single thing they possibly can, somewhere along all of your simulation preparation. So that no matter what system fails, no matter what combinations of systems have any probability of failing, you are going to be able to handle it. And the place that you really perfect those skills is in the simulator. It is the crucible where you grind everything together and see whether you're ready for spaceflight or not. There's something I want you to remember. This is really important, especially in a career of an astronaut. And that is all simulators are wrong. Seems counterintuitive. But it's a simulator. It's not the real thing. And even if it's really, really close, even if it's Kerbal Space Program, or even if it's some sort of great asteroids game, it may have some similarity to what you're really going to do in space. But it's going to be slightly different. There are lots of classic examples of...
