<passage>:
The meteor, a pebble, a little larger than a match head, traveled through space and time since it came into being. The light from the star that died when the meteor was created fell on Earth before the first lungfish ventured from the sea. In its last instant, the meteor fell on the Moon. It was impeded by Evans' tractor. It drilled a small, neat hole through the casing of the steam turbine, "Well, it was to rescue you that I came." landed. When he was flush, he would prospect for a couple of weeks. Once he followed a stampede to Yellow Crater, where he thought for a while that he had a fortune in chromium. The chromite petered out in a month and a half, and he was lucky to break even. "Claim?" the first landing on the Moon. on the Moon!" "Sure, man, I've thousands of tons of water here. It's the richest mine THE END In seventeen days he might be missed, but in seventeen days it would be dark again, and the search for him, if it ever began, could not begin for thirteen more days. At the earliest it would be eight days too late. into the cold darkness of space. When the meteor pierced the turbine, the water in the condenser began to boil. This boiling lowered the temperature, and the condenser demonstrated its efficiency by quickly used. It was one day's supply if used wastefully. It was ostentatious It was an incredibly brilliant disk in a black sky. The stars next to the sun shone as brightly as though there were no sun. They might have to function properly, and to prevent air loss in case of the highly improbable meteor damage. McIlroy thought that on the whole, he was Everyone in the survey except McIlroy realized this, and even he accepted this without thinking about it. He had fallen into the habit of on the Moon for another week. "Has the power crew set up the solar furnace?" he asked. The solar anything that it was desirable to heat. It was used mostly, from sun-up to sun-down, to supplement the nuclear power plant. over the assets of the Survey Credit Association all morning." "I'll certainly be glad to get them off my hands," McIlroy said. "I hope "There doesn't seem to be any profit," Mr. Phelps said. "That's par for a nonprofit organization," said McIlroy. "But we're Nobody answered. They could all see the Moon under their feet. Small craters overlapped and touched each other. There was—except in the that didn't contain a crater at least ten inches across, there was not a square inch without its half-inch crater. Nearly all of these had been made millions of years ago, but here and there, the rim of a crater covered part of a footprint, clear evidence that it was a recent one. be, zeolites need water to form, and there's no water on the Moon." across." All of these needed water to form, and their existence on the Moon puzzled him for a while. Then he opened the bag that had contained the the sun. Earth remained in the same spot in the black sky. The shadow line crept around until Earth was nearly dark, and then the rim of light appeared on the opposite side. For a while Earth was a dark disk in a thin halo, and then the light came to be a crescent, and the line of dawn began to move around Earth. The continents drifted across the dark disk and into the crescent. The people on Earth saw the full moon set about the same time that the sun rose. to the Moon about once a month, carrying supplies in and metal and ores "I swear, Mac," said Jones, "another season like this, and I'm going back to mining." drinks from a bottle of Scotch that Jones had brought him. "Oh, the money I like, but I will say that I'd have more if I didn't have to fight the union and the Lunar Trade Commission." McIlroy had heard all of this before. "How's that?" he asked politely. "You may think it's myself running the ship," Jones started on his "Near cost it is now at a dollar forty. But what sense is there in charging the same rate to go either way when it takes about a seventh of the fuel to get from here to Earth as it does to get from there to here?" "The nickel, man, the tons of nickel worth a dollar and a half on Earth, and not worth mining here the low-grade ores of uranium and vanadium, they need these things on Earth, but they can't get them as long as it isn't worth the carrying of them. And then, of course, there's the water we haven't got. We could afford to bring more water for more people, and set up more distilling plants if we had the money from the nickel. "Even though I say it who shouldn't, two-eighty a quart is too much to "Have you seen our friend Evans lately? The price of chromium has gone up, and I think he could ship some of his ore from Yellow Crater at a profit." The sun was halfway to the horizon, and Earth was a crescent in the sky thought grew on him as he worked that this couldn't be the only such Part of his reasoning proved correct. That is, he found that by one with its droplet of water. The average was about one per cent of the mound of lava. It was rounded on top, and it could easily be the dome of his suit was reading dangerously near empty. He turned back to his tractor, moving as slowly as he felt safe in doing. Running would use up efficient as the one in the tractor it wasted oxygen. By using the suit so much, Evans had already shortened his life by several days. He resolved not to leave the tractor again, and reluctantly abandoned his The sun stood at half its diameter above the horizon. The shadows of the dawning line of light covered half of Earth, and Earth turned beneath it. ruptured. A stream of mud gushed out and boiled dry on the face of the Moon. Cowalczk and Lehman rushed forward again. They could see the trickle of water from the discharge pipe. The motor power in it to crush the scale." "Think we weren't worried?" Lehman asked. "And it's not over." "What?" Cade asked. "Oh, you mean the valve servo you two bashed up?" "No," said Lehman, "I mean the two thousand gallons of water that we the solar furnace as a radiator, we can make do." "Oh, God, I suppose this means water rationing again." "You're probably right, at least until the next rocket lands in a couple of weeks." PROSPECTOR FEARED LOST ON MOON McIlroy released a statement today that Howard Evans, a prospector is missing and presumed lost. Evans, who was apparently exploring the Moon in search of minerals was due two days ago, but it was presumed that he was merely temporarily delayed. Evans began his exploration on August 25th, and was known to be McIlroy has expressed a hope that Evans will be found before his oxygen runs out. search from Palomar and the new satellite observatory are hindered by the fact that Evans is lost on the part of the Moon which is now dark. Little hope is held for radio contact with the missing man as McIlroy chuckled for the first time in several days. "So that's the rocket would be needed in the search." The light from Earth lighted the Moon as the Moon had never lighted Earth. The great blue globe of Earth, the only thing larger than the stars, wheeled silently in the sky. As it turned, the shadow of sunset crept across the face that could be seen from the Moon. From full Earth, as you might say, it moved toward last quarter. are clouded over. Anyway the satellite observatory will be in position by the time Europe is." finding him. It began to dawn on McIlroy that nearly the whole population of Williamson Town was involved, one way or another, in the
