" What we want you to ask yourselves is this: what is space, to you? Is it a playground? A quarry? A flagpole? A classroom? A temple? Who do you believe should go, and for what purpose? Or should we go at all? Is the realm above the clouds immaterial to you, so long as satellites send messages and rocks don't fall? Is human spaceflight a fool's errand, a rich man's fantasy, an unacceptable waste of life and metal? Are our methods grotesque to you, our ethics untenable? Are our hopes outdates? When I tell you of our life out here, do you cheer for us, or do you scoff?
Are astronauts still relevant in your time? "
