<passage>:
evil jack-in-the-box at night. I must tell you, Laura. and skin-tight. I was worshiping him and hating him at the same time, for I was thinking: He's already reached Mars and Venus. Let him leave Jupiter and the others alone! Let us be the first to land somewhere! Let us be the first! That was something I didn't have to worry about. My parents had died in a strato-jet crash when I was four, so I hadn't needed many of those "You are cordially invited" cards. Just one, which I'd sent to Charlie Spaceport, tagging after him like a puppy, and how he'd grown to like me until he became father, mother, and buddy all in one to me. And I It doesn't matter we'd been a good team during those final months at the Academy and I knew we'd be a good team in space. The Universe was mighty big, but with two of us to face it together, it would be only "I'm happy to meet you, Ben," you said. "I've heard of no one else for to reach the Moon!" Charlie gulped helplessly, and Mickey said: "Still going to spend the weekend with us, aren't you, Ben?" I shook my head. "Charlie has only twenty-four hours liberty. We're "Why don't you both come with us?" you asked. "Our folks have their own plane, so it would be no problem. And we've got a big guest room. that he'd infinitely prefer to spend his liberty sampling Martian fizzes and Plutonian zombies. should look. "Ben," he called, "don't forget that offer. Remember you've got two months to decide." "No, thanks," I answered. "Better not count on me." A moment later Mickey said, frowning, "What was he talking about, Ben? "What did she mean, Mickey?" Mickey looked down at his feet. "I didn't want to tell you yet, Ben. We've been together a long time, planning to be on a rocket. But—" "Yes?" you're lucky, you're good for five, maybe ten years. Then one thing or another gets you. They don't insure rocketmen, you know." "I've thought about it a long time. They want me for Cargo Supervisor of White Sands Port." He raised his hand to stop me. "I know. It's not so exciting. I'll just live a lot longer. I'm sorry, Ben." I couldn't answer. It was as if someone had whacked the back of my knees with the blast of a jet. "It doesn't change anything, Ben—right now, I mean. We can still have a good weekend." Charlie was muttering under his breath, smoldering like a bomb about to spaceman then." "But he wasn't always a spaceman. Didn't he ever have a family?" I smiled and shook my head. "If he had, he never mentioned it. Charlie doesn't like to be sentimental, at least not on the outside. As far as I know, his life began when he took off for the Moon with Everson." Laura?" I frowned. "And you mean it might be the same with the stars? You think maybe I haven't grown up yet?" Anxiety darkened your features. "No, it'd be good to be a spaceman, to see the strange places and make history. But is it worth it? Is it worth the things you'd have to give up?" ten years as normal men do in fifty. You can be like Everson, who died in a Moon crash at the age of 36, or like a thousand others who lie buried in Martian sand and Venusian dust. Or, if you're lucky, like Charlie—a kind of human meteor streaking through space, eternally alone, never finding a home. Or there's the other path. To stay on this little prison of an Earth a wife and kids. To be one of the people who live long enough to grow old, who awake to the song of birds instead of rocket grumblings, who fill their lungs with the clean rich air of Earth instead of poisonous it's just that I've been dodgin' meteors now for twenty-five years. That's a long time, boy. Ain't one spaceman in a thousand that lucky. Some of these days, I won't be so lucky." drugged. I shook the thought away. If Charlie was sick, he wouldn't talk about going to Mars. The medics wouldn't let him go even as far as Luna. I wanted him to say something, to tell me the secret that would kill "What's the matter, Ben? Still sore? I feel like a heel, but I'm just not like you and Charlie, I guess. I—" too, for the Moon Patrol, but that's old stuff, not much better than teaching. I want to be in deep space." "Well, how about staying with us till you decide? Might as well enjoy Earth life while you can. Okay?" But I wanted, also, to be with you, Laura, to see your smile and the Why must I make a choice? Why can't I have both you and the stars? Would that be asking too much? All day the thought lay in my mind like fire. That evening I asked you to marry me. I said it very simply: "Laura, I You looked up at Venus, and you were silent for a long while, your face flushed. Then you murmured, "I—I want to marry you, Ben, but are you asking me to marry a spaceman or a teacher?" "Can't a spaceman marry, too?" "Yes, a spaceman can marry, but what would it be like? Don't you see, Ben? You'd be like Charlie. Gone for maybe two months, Somehow I'd expected words like these, but still they hurt. "I wouldn't have to be a spaceman forever. I could try it for a couple of years, then teach." "Would you, Ben? Would you be satisfied with just seeing Mars? Wouldn't you want to go on to Jupiter and Saturn and Uranus and on and on?" Your voice was choked, and even in the semi-darkness I saw tears "Do you think I'd dare have children, Ben? Mickey told me what happened on the Cyclops . There was a leak in the atomic engines. The ship was flooded with radiation—just for a second. It didn't seem serious. The men had no burns. But a year later the captain had a child. And it was—" "I know, Laura. Don't say it." open—and the big ship, it was rumored, was equipped to make it all the way to Pluto. You can take Dean Dawson's job and stay with Laura and have kids and a home and live to see what happens in this world sixty years from now. And yet I wanted you, Laura. I wanted to be with you, always. voice droned on. You ran to it, shut it off. "I'm sorry, Ben, so terribly—" And now, Laura, it's nearly midnight. You're in your room, sleeping, travel both. He later learned what we already know—that there can be no compromise. And you know, too, which path he finally chose. Do you know why he had to drug himself to watch me graduate? So he why he wanted to reach Mars? Do you know why he didn't want to die in the clean, cool air of Earth? It was because he wanted to die nearer home. His home, Laura, was the Universe, where the ship was his house, the crew his father, mother, brothers, the planets his children. Because of these things, Laura, I will be gone in the morning. Explain he'll go with me in memory to whatever part of the Galaxy I may live to reach. And so will you, Laura. I have two wedding rings with me—his wife's ring and yours.
