Thin, scratchy, inaudible more than a yard away, weary human voice. "I've tried my hands and arms and they seem to work," it began. That's why I can't seem to get up. Who wouldn't be shocked after luck Whale . Sure I'm a good astronomer but so are lots of other guys. If I were ten years older, it would have been an honor, being picked for the first long jump in the first starship ever. At my age it was luck. Earth and Mars, you'll remember, and James pushed the button marked 'Jump'. Took his finger off the button Alpha Centauri doubt if it was the ship itself that fouled things up. "That was some survey assignment. We astronomers really lived. Wait till you see—but of course you who I was. Matt Hennessy, from Farside Observatory, back of the Moon, just back from a proving flight cum astronomical survey in the starship Whale . Whoever you are who finds this tape, you're made. Take it to and don't take any wooden nickels. "Where had I got to? I'd told you how we happened to find Chang, hadn't I? That's what the natives called it. Walking, talking natives on a blue sky planet with 1.1 g gravity and a twenty per cent oxygen atmosphere at fifteen p.s.i. The odds against finding Chang on a six-sun survey on the first star jump ever must be up in the googols. We certainly were lucky. "The Chang natives aren't very technical—haven't got space travel for instance. They're good astronomers, though. We were able to show them our sun, in their telescopes. In their way, they're a highly civilized people. Look more like cats than people, but they're people all right. If you doubt it, chew these facts over. "One, they learned our language in four weeks. When I say they, I mean a ten-man team of them. "Three, they've a great sense of myself, but tastes differ. "Four, the ten-man language team also learned chess and table tennis. "But why go on? People who talk English, drink beer, like jokes and beat me at chess or table-tennis are people for my money, even if they look like tigers in trousers. was our champion. He won sometimes. The rest of us seemed to lose whichever Chingsi we played. broken or a clockwork toy running There again it wasn't so much that playing chess with something that grows its own fur coat, has yellow "And don't think I fell victim to I knew best. He was called—well, we called him Charley, and he was the ethnologist, ambassador, contact man, or whatever you like to call him, who came back with us. Why I disliked him was because he was always trying time he had to be top. Great sense Charley ... unhurt, was Charley. He was laughing ... "My God, it's dark out here. Wonder how high I am. Must be all of final velocity for a fifty-mile fall? "It's getting lighter. Look at those peaks down there! Like great knives. I don't seem to be falling as fast as I expected though. Almost seem to be floating. Let's switch on the radio and tell the world hello. Hello, earth ... hello, again ... and good-by ... "No. I'd have to get up to do that. up. journey, wasn't I? The long jump back home, which should have dumped us between the orbits of Earth and Mars. Instead of which, when James took his finger off the button, the mass-detector showed nothing a day. We astronomers had to establish our exact position relative to the solar system. The crew had to find out exactly what went wrong. The physicists had to make mystic passes Our task was easy, because we were about half a light-year from the sun. The crew's job was also easy: they found what went wrong in less than the wrong place. It hurts me to tell you this and I'm just attached personnel with no space-flight tradition. In practical terms, one highly trained equally skilled had failed to notice this when reading back. A childish Incredible, but that's what worth. We were all praying that this time nothing would go wrong, and all looking forward to seeing Earth again after four months subjective time away, except for Charley, who was still chuckling and shaking his glaring at Charley and obviously wishing human dignity permitted him poured back into shape. The entire bow wall-screen was full of Earth. Something was wrong all right, and two hundred miles above the Pacific, pointed straight down, traveling at a was the , the most powerful "The "James got us all into the Minnow was meant for short heavy hops to planets or asteroids. In addition to the ion drive canceled our downwards velocity with them in a few seconds. We curved away up over China and from about fifty miles high we saw the "I wonder why James went down have broken his heart to know that his lovely ship was getting the chopper. Or did he suspect another human error? sky. I tumbled head over heels towards "I'll have to get up and crack this I fell fifty miles without a parachute. I'm dead so I can't stand up." ledge. A man crawled stiffly out and came shakily to his feet. He moved slowly around for some time. After about two hours he returned to the on the recorder. The voice began again, considerably wearier. "Hello there. I'm in the bleakest wilderness I've ever seen. This place makes the moon look cozy. There's word. Not English, not French, and there I stick. Listened to it for fifteen minutes just to hear a human voice again. I haven't much hope of reaching "Just before I start the climb there are two things I want to get on tape. The first is how I got here. I've remembered something from my military human body falling through air is Falling fifty miles is no worse than falling five hundred feet. You'd be mountain, skidded downhill through "The second thing I want to say is about the Chingsi, and here it is: watch out for them. Those jokers are dangerous. I'm not telling how because I've got a scientific reputation to watch. You'll have to figure it out for yourselves. Here are the clues: (1) The Chingsi talk and laugh but after all they aren't human. On an alien world a hundred light-years away, why shouldn't alien talents develop? A talent that's so uncertain and rudimentary here that most people don't believe it, might be highly developed out there. (2) The Whale expedition did fine till it found Chang. Then it hit a seam of bad luck. Real stinking bad luck that went on and ping-pong. "So what is luck, good or bad? Scientifically speaking, future chance For him, luck refers to the way. Scientific investigations into this have been inconclusive, but everyone others aren't. All we've got are hints enough. "All the same, search the space-flight records, talk to the actuaries.
