And you recall staring out there at the spectacle that went before your eyes. Because now you’re no longer inside something with a window looking out at a picture, but now you’re out there and what you’ve got around your head is a goldfish bowl and there are no limits here. There are no frames, there are no boundaries. You’re really out there, over it, floating, going 25,000 mph, ripping through space, a vacuum, and there’s not a sound. There’s a silence the depth of which you’ve never experienced before, and that silence contrasts so markedly with the scenery, with what you’re seeing, and the speed with which you know you’re going. That contrast, the mix of those two things, really comes through.
Russell Schweickart, No Frames, No Boundaries Connecting with the whole planet - from space, 1983
