It changed my perspective because rather than standing on the earth looking up at the universe, instead I was in the universe with the earth, with the world. And that’s a different perspective – to see the world not as some vast mother but instead to be just another small planet orbiting a small star. And to be on a spacewalk you really see that difference in perspective because you have seen the world by yourself alone in the universe as something that is flying through the universe with you. I think it’s quite humbling.
