Chris Hadfield: How looking at 4 billion years of Earth’s history changes you

What is it like to see humanity from space? Imagine being able to tour our 4 billion-year-old planet 16 times a day, and see a sunset every 45 minutes. Chris Hadfield, the first Canadian astronaut to walk in space, has done just that—and it has opened his eyes and his mind to the idea that, from above, we're not so different at all.

And, as you’re raised, your parents are probably trying to control the environment that you’re in and so you end up with a very centralized, tiny little view of the world—naturally. As you get older, as you travel more, as you read more, you start to understand a little more of the world around you; and all of those influences affect your choices in life. What are you going to imagine that you could be? If you’ve never left Main Street, small town, Ohio, then you’re probably not going to visualize yourself doing something that is wildly different than that. You’re never going to be the head of a religious sect in Pakistan; it’s not inside your worldview. You can only draw your own aspirations and hopes and decisions based on the things that you even know exist. It’s easier now to understand and see the world than ever in history. Our ability to communicate and our ability to travel has greatly improved. But space travel is sort of like the wildly exaggerated version of that, where you can go around the whole world in the time it takes to eat supper, and see everywhere, see the whole world 16 times a day. That widens and deepens your worldview like nothing we’ve ever seen before in history. And it’s very difficult to maintain artificially drawn biases like nationalistic borders and “my little tribe”, “my little street”, “my little gang”, “my little town”, my little whatever when, 15 minutes later, you’re over at the exact same-looking sort of town—but it’s in Africa, and 40 minutes later the exact same-looking sort of town and it’s in Australia—and then you come up to Indonesia—and you go, “Man, it’s all the same. They build their towns just like we build our towns, and how are they “They” then? It’s just sort of all “Us”. We’re all doing this thing together, and everyone has got the same sort of hopes and dreams amongst themselves. And that pervasive sense of the shared collective experience of being a human being, that seeps into you onboard a spaceship. Not the first time around. The first time is overwhelming, but somewhere, you know, a hundred times around, 500 times around, suddenly the world becomes one place in your mind. It’s not very big, and that I think is a really important worldview to have. Life can be full of magnificent experiences. Being at the wedding of a loved one in a beautiful, big house of worship somewhere where there’s the sound and the beauty and the structure—it affects how you feel that day, and you act a little bit differently. Or walking into a gigantic ancient redwood forest, your head is naturally drawn upwards and you think a little different. It’s not the same as just walking down your street. Imagine what it’s like on a spaceship, where you’re floating weightless at a window, where you see an entire continent in the time it takes to drink a cup of coffee, where you go from L.A. to New York in nine minutes and you see all of that history and culture and climate and geography and geology, and it’s all right there underneath you. And you see a sunrise or a sunset every 45 minutes; you see the world for what it actually is. It has that same sort of personal effect on you, of a feeling of privilege and sort of a reverence, an awe that is pervasive. When we’re floating in the bulging window, the Cupola of the space station—normally it’s just one person because everybody is busy, but if there is two of you in there—you talk in hushed tones to each other just because you feel like you’re just wildly lucky to even be there to see this happening.
