"In space, you can't see the borders. It doesn't look like a map. We're all like kids fighting in a sandbox, on the political and human side of it. The International Space Station was built in orbit. Each piece hurtled into space at eight kilometres per second. From an engineering point of view, it's madness. It's also a feat of policy - Russia, the U.S., Germany and Japan working together. Do you realize what that means? These countries were sending nukes to each other a generation ago. Space does that. It gives us that amazing big picture."
