Not that he was ashamed of Pop it wasn't that at all. It straight, his shoulders broad and firm. Standing beside him made Pop look sort of thin and puny his chest caved in like he was carrying a heavy weight on his shoulders. Bobby with a fierce loyalty, that S.S.P. man probably wouldn't even know what to look for if somebody put a microscope in front of him. Even if he was big and sturdy and broad-shouldered in his space blues. Mom said, "Bobby, what are you muttering about? Do stop fidgeting!" Bobby said, "Yessum," and glared at Moira, as if she, in some obscure way, were to blame for his having been reprimanded right out here in the middle of Long Island Spaceport, where everybody could Vast cradles by the Sound were the nests to which a flock of interplanetary craft made homeward flight. Luggers and barges and cruisers. Bobby saw, with sudden excitement, the sharp, starred prow of one of which, as soon as Pop got clearance, their ship would take off. Their ship! Bobby felt an eager quickening of his pulse his stomach was aswarm with a host of butterflies. "Thank you," said Pop quietly. He turned. "That's all. Ready, Mother? Eleanor? Moira?" Bobby bounded forward. "Can I push the button, can I, Pop? When we start, can I?" Dick was waiting before the open lock of the his left arm, helped his mother aboard, said, "Shut up, kid, you're enough to wake the dead. Watch that guard-panel, Elly. Papers all set, Pop?" And he tickled The Pooch's dimpled cheek with an oily finger. "You act just like your mama," he said irrelevantly, and the baby "Good. You folks go in and strap down. I'll seal. Here comes the cradle-monkey now." Pop said, "Come along, Robert," and the others went inside. Bobby "Well, f'r goddlemighty' sakes, don't try to blast off with y'r side saw him. "What are you doing here, kid? Didn't I hear Pop tell you to come below?" Bobby said, "I'm not a kid. I'm almost sixteen." "Just old enough," promised Dick, "to get your seat warmed if you don't do what you're told. Remember, you're a sailor on a spaceship now. Pop's the Skipper, and I'm First Mate. If you don't obey orders, it's mutiny, and—" "I'm obeying," said Bobby hastily. He followed his brother down the corridor, up the ramp, to the bridge. "Can I push the button when we take off, huh, Dick?" word, kid." Of course, he got to sit in the pilot's bucket-chair, which understanding response fell again. "Now!" Bobby jabbed the button in frantic haste. Suddenly the silence was But Pop was standing by the observation pane, eyeing an Earth already ball-like in the vastness of space. Earth, dwindling with each passing moment.

So they ate and they slept and they ate again. And Pop and Dick spelled Pop said, "You deserve a great deal of credit, son, for your fine work Dick flushed. "She's a good ship, Pop, even if she is thirty years old. and trajectory?" are necessary, set brakes." Pop smiled happily. "We're very fortunate, son. A mere fifteen million miles. It's not often Eros is so near Earth." "Not so fast, son. Eventually, perhaps not today. First we must plenty of hard work. After that, we might be able to consider a mining operation. What's that?" Bobby jumped. It was Mom's voice. But her cry was not one of fear, it was one of excitement. "Rob, look! Off to the—the left, or the port, or whatever you call it! Is that our new home?" Bobby did not need to hear Pop's reply to know that it was. His swift intake of breath was enough, the shine in his eyes as he peered out the observation port. It looked all right to Bobby. A nice, clean little sphere, spinning lazily before their eyes like a top someone had set in motion, then gone away and forgotten. Silver and green and rusty brown, all still It was, thought Bobby, not a bad looking little place. But not anything to get all dewy-eyed about, like Pop was. the irrevocable movements of a grounding spaceship. Dick should have "Well, blast me for an Earth-lubbing idiot! Do you see that, Pop?" his cane on the floor. "They's absolutely nothin'," he informed the walls, "to this hereditation stuff. Elst why should my own son an' his son be so That was sheer optimism. As they neared the planet its gravitational And then, suddenly— "Hold tight! We're grounding!" cried Dick. And instinctively Bobby braced himself for a shock. But there was only a shuddering jar, a lessening of the roar that beat upon their eardrums, a dull, flat thud. A sodden, heavy grinding and the groan of Pop unbuckled his safety belt, climbed gingerly out of his hammock, moved to the port, slid back its lock-plate. Bobby said, "Can you see anything, Pop? Can you?" And Mom, who could read Pop's expressions like a book, said, "What is it, Rob?" Pop stroked his chin. He said, "Well, we've landed safely, Richard. But frightening, but to Bobby it was thrilling, too. This was the sort of thing you read stories about. Escape from a flooding ship.... They had time—or took time—to gather together a few precious Dick. Bobby, whose imagination had already assigned him the command of the foundering ship, wanted to uphold the ancient traditions by being the last to leave. But Dick had other ideas. He shoved Bobby—not too He stepped forward. And floated upward, feeling an uneasy, quibbly Pop said, "The ship, Richard?" warm, safe rubber rowboat. The stars winked at him, the soft waves Dick asked, "Isn't that a remarkably slow rotation? For such a tiny More than that, though—" Pop lifted his face to the skies, now blue us to dare, as did our forefathers. But still within us all stirs the deep, instinctive longing to hew a new home from virgin land—" His words dwindled into silence, and, inexplicably, Bobby felt awed. It was Grampaw Moseley who burst the queer moment into a thousand spluttering fragments. Bobby and I will get some wood." Thus Eros greeted its new masters, and the Moseleys faced morning in Pop said seriously, "I'm afraid you'll have to eat them and like them "Let him eat, Rob," said Mom. "He's hungry."
