Castaways of Eros By NELSON S. BOND Two families fought for the title to Eros, and only one could win. One had to outsmart the other—and both had to win over the "Why not now? There's nothing to keep us here." was a problem worthy of a Solomon—and it had an ending even those embittered lazily to the sea. Small wonders unfolded before their eyes. Marching along, they had discovered that there was game on Eros. Not quite Earthly, of course—but that was not to be expected. There was one small, furry beast about the size of a rabbit, only its color was vivid leaf-green. rivals could not foresee. straighter. Not that he was ashamed of Pop and firm. Standing beside him made Pop look sort of thin and puny "There would have to be insects," Pop said. "There could be no fruitful bubbling water was nearby, because the woodlands dwindled away into lush fields. And Pop said, "This is it. We'll build our home on yonder knoll. And who knows—" Again there grew that strange look in his eyes. "Who knows but that you muttering about? Do stop fidgeting!" it may be the shoot from which, a time hence, there may spring many "That's it, Pop!" said Dick suddenly. "There's the name for our one of which, as soon as Pop got clearance, their ship would take off. Pop?" And he tickled The Pooch's dimpled cheek with an oily finger. "Everything is in order, Richard," said Pop. "Family crate, huh?" saw him. "What are you doing here, kid? Didn't I hear Pop tell you to mutiny, and—" "I'm obeying," said Bobby hastily. He followed his brother down the After his high expectations, it wasn't such a great thrill. Dick set ears and nerves, as the slow seconds sloughed away. Pop set the hypos But Pop was standing by the observation pane, eyeing an Earth already you and the children. Perhaps it isn't right that I should force my dream on all of you. The world we have known and loved lies behind us. Before us lies only uncertainty...." Which offended Bobby, who was sixteen, or, anyway, fifteen and So they ate and they slept and they ate again. And Pop and Dick spelled the ship. And somehow three Earth days sped by, and they were nearing their destination. The tiny planetoid, Eros. Pop said, "You deserve a great deal of credit, son, for your fine work in rehabilitating the Dick flushed. "She's a good ship, Pop, even if she is thirty years old. drives at 19.04.22 precisely and make such minor course alterations as 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." "Don't I know it? It's almost a hundred million at perihelion. But that's not the lucky part. You sure had to pull strings to get the government land grant to Eros. What a plum! Atmosphere ... water ... vegetable life ... all on a hunk of dirt fifty-seven miles in diameter. Frankly, I don't get it! Eros must have terrific mass to have the attributes of a full-sized planet." "It does, Richard. A neutronium core." Roaring craters, Pop, we're rich! Bloated plutocrats!" "Not so fast, son. Eventually, perhaps not today. First we must establish our claims, justify our right to own Eros. That means work, plenty of hard work. After that, we might be able to consider a mining operation. What's that?" intake of breath was enough, the shine in his eyes as he peered out the observation port. "Eros!" he said. 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 to get all dewy-eyed about, like Pop was. Eros was just a mote. A spinning top.... Anyway, it was after the final coordinates had been plotted, the last "Well, blast me for an Earth-lubbing idiot! Do you see that, Pop?" Pop looked like he had shared Dick's persimmon. "The night-line. We forgot to consider the diurnal revolution." But there was perspiration on his forehead, and his fingers played over the control banks like frightened moths. There was no further need for the artificial gravs. Eros exerted, strangely, incredibly, an attractive power almost as potent as Earth's. Pop's Pop unbuckled his safety belt, climbed gingerly out of his hammock, Pop stroked his chin. He said, "Well, we've landed safely, Richard. But Dick cried, "Hey, this is bad! We'd better get out of here—" Mom cried, "But—but our supplies, Dick! What are we going to do for food, clothing, furniture—?" "We'll worry about that later. Right now we've got to think of Pop Pop said, "The ship, Richard?" looked upon this land which was their new home—and found it good. The night did not last long. But Pop had told them it would not. "Eros rotates on its axis," he explained, "in about ten hours, forty minutes, Earth time measurement. Therefore we shall have 'days' and 'nights' of five hours somewhat, you understand, with the change of seasons." Dick asked, "Isn't that a remarkably slow rotation? For such a tiny planet, I mean? After all, Eros is only one hundred and eighty odd miles in circumference—" "Eros has many peculiarities. Some of them we have discussed before. It approaches Earth nearer than any other celestial body, excepting Luna and an occasional meteor or comet. When first discovered by Witt, in Mars at aphelion it is far outside. "During its near approach in 1900-01, Eros was seen to vary in brightness at intervals of five hours and fifteen or twenty minutes. At that time, a few of the more imaginative astronomers offered the After 1931, though, the planetoid fled from Earth. It was not until 1975, the period of its next approach, that the Ronaldson-Chenwith expedition visited it and determined the old presumption to be correct." "We're not the first men to visit Eros, then?" "Not at all. It was investigated early in the days of spaceflight. Two research foundations, the Royal Cosmographic Society and the "That is why," concluded Pop, "we are here now. As long as I can remember, it has been my dream to take a land-grant colony for my very own. Long years ago I decided that Eros should be my settlement. As you have said, Richard, it necessitated the pulling of many strings. Eros is a wealthy little planet blankets and spare clothing to dry? Grampaw, get a fire going. Pop and Bobby and I will get some wood." Thus Eros greeted its new masters, and the Moseleys faced morning in their new Eden. III Four Eros days—the equivalent of forty-two Earth hours or so—had passed since their crash landing. In that short time, much had been done to make their beach camp-site comfortable. All members of the Pop said seriously, "I'm afraid you'll have to eat them and like them "I'll eat 'em," grumbled Grampaw, "but be durned if I'll like 'em. over-supplied." He thought for a minute. "If that's the way it is, we might as well move." "Move?" demanded Grampaw. "What's the matter with the place we're at?" "For one thing, it's too exposed. An open beach is no place for a permanent habitation. So far we've been very lucky. We've had no Pop?"
