“Our three big emergencies are fire, loss of pressurization or contamin...” — Chris Hadfield Quote

Our three big emergencies are fire, loss of pressurization or contaminated atmosphere. Any of those things in a spaceship are very deadly and time critical. Everybody's trained, but I'm the commander of the ship, and it's up to me to decide.

And then finally, I'm the commander, so I am fundamentally responsible for the lives of the other people on board and the health and longevity of the space station. I need to bring six people back happy, healthy and feeling like they've had the best six months of their life.

If you don't like airline food, you'll probably have the same impression of space station food. I would not fly to space for the food.

You should have a fear of some things. That doesn't mean it incapacitates you from your ability to figure out a way to deal with it.

What draws us to a city like San Francisco is the same thing that draws entrepreneurs, startups, and freelancers to WeWork: it's the creative atmosphere, the technical sophistication, and the strong sense of community.

I believe if the atmosphere on the set is positive, it definitely reflects on the screen. Your work becomes easy if the environment on the set is healthy and positive.

Yes - it's a lot of people, it's craziness, but I really like to walk around and just feel the atmosphere of New York.

Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth's temperatures would cool dozens of degrees below your comfort zone.
