Best of all, though, he was thoroughly expendable.
So Jason made a deal with him. There could be no expeditions into the cities until the satellite was finished, because every man was needed at the settlement. And the satellite could not be finished until someone volunteered to go up in the rocket and assemble it.
It was like holding a candy bar in front of a small child. He accepted Jason’s terms.
The Earth turned, and with it the tiny spark of life alone in the emptiness around the satellite. Tom worked unmindful of time, his eyes and hands following Jason’s engineering commands through Arnoldsson’s post-hypnotic directions, with occasional radio conferences.
But his conscious mind sought refuge from the strangeness of space, and he talked almost constantly into his radio while he worked, talked about anything, everything, to the woman on the other end of the invisible link.
«… and once the settlement is getting the power beamed from this contraption, we’re going to explore the cities. Guess we won’t be able to get very far inland, but we can still tackle Washington, Philadelphia and New York … plenty for us there.»
Ruth asked, «What were they like before the war?»
«The cities? That’s right, you’re too young to remember. They were big, Ruth, with buildings so tall people called them skyscrapers.» He pulled a wrench from its magnetic holder in the satellite’s self-contained tool bin. «And filled with life, millions of people lived in each one … all the people we have at the settlement could have lived on one floor of a good-sized hotel.»
«What’s a hotel?»
Tom grinned as he tugged at a pipe fitting. «You’ll find out when you come with us … you’ll see things you could never imagine.»
«I don’t know if I’ll come with you.»
He looked up from his work and stared Earthward. «Why?»
«Well … Jason … he says there isn’t much left to see. And it’s all radioactive and diseased.»
«Nonsense.»
«But Jason says …»
Tom snorted. «Jason hasn’t been out of the settlement for six years. I walked from Chicago to the settlement a year ago. I went through a dozen cities … they’re wrecked, and the radioactivity count was higher than it is at the settlement, but it’s not high enough to be dangerous.»
«And you want to explore those cities; why?»
«Let’s just say I’m a historian,» Tom answered while his hands manipulated complex wiring unconsciously, as though they belonged not to him but to some unseen puppeteer.
«I don’t understand,» Ruth said.
«Look—those cities hold mankind’s memory. I want to gather up the fragments of civilization before the last book is used for kindling and the last machine turns to rust. We need the knowledge in the cities if we expect to rebuild a civilization.»
«But Jason and Dr. Arnoldsson and the engineers—they know all about—»
«Jason and the engineers,» Tom snapped. «They had to stretch themselves to the breaking point to put together this rocket from parts that were already manufactured, waiting for them. Do you think they’d know how to build a city? Dr. Arnoldsson is a psychiatrist, his efforts at surgery are pathetic. Have you ever seen him try to set a broken leg? And what about agriculture? What about tool making or mining or digging wells, even … what about education? How many kids your own age can read or write?»
«But the satellite …»
«The satellite won’t be of any use to people who can’t work the machines. The satellite is no substitute for knowledge. Unless something is done, your grandchildren will be worshipping the machines, but they won’t know how to repair them.»
«No …»
«Yes, Ruth,» he insisted.
«No,» she whispered, her voice barely audible over the static-streaked hum in his earphones. «You’re wrong, Tom. You’re wrong. The satellite will send us the power we need. Then we’ll build our machines and teach our children.»
How can you teach what you don’t know? Tom wanted to ask, but didn’t. He worked without talking, hauling the weightless tons of satellite packages into position, electronically welding them together, splicing wiring systems too intricate for his conscious mind to understand.
Twice he pulled himself back along the lifeline into the ship for capsule meals and stimulants.
Finally he found himself staring at his gloved hands moving industriously within the bowels of one of the satellite packages. He stopped, suddenly aware that it was piercingly cold and totally dark except for the lamp on his helmet.
He pushed away from the unfinished satellite. Two of the packages were assembled now. The big parabolic mirror and two other uncrated units hung nearby, waiting impassively.
Tom groped his way back into the ship. After taking off his helmet and swallowing a couple of energy pills he said to the ship’s radio:
«What time is it?» The abrupt sound of his own voice half-startled him.
«Nearly four a.m.» It was Jason.
«Earth’s blotted out the sun,» Tom muttered. «Getting damned cold in here.»
«You’re in the ship?»
«Yes, it got too cold for the suit.»
«Turn up the ship’s heaters,» Jason said. «What’s the temperature in there?»
Tom glanced at the thermometer as he twisted the thermostat dial as far as it would go. «Forty-nine,» he answered.
He could sense Jason nod. «The heaters are on minimum power automatically unless you turn them up. It’ll warm you up in a few seconds. How’s the satellite?»
Tom told him what remained to be done.
«You’re not even half through yet.» Jason’s voice grew fainter and Tom knew that he was doing some mental arithmetic as he thought out loud. «You’ve been up about twenty hours; at the rate you’re going you’ll need another twenty-four to finish the job. That will bring you very close to your oxygen limit.»
Tom sat impassively and stared at the gray metal and colored knobs of the radio.
«Is everything going all right?» Jason asked.
«How should I know? Ask Arnoldsson.»
«He’s asleep. They all are.»
«Except you.»
«That’s right,» Jason said, «except me.»
«How long did Ruth stay on the radio?»
«About sixteen hours. I ordered her to sleep a few hours ago.»
«You’re pretty good at giving orders,» Tom said.
«Someone has to.»
«Yeah.» Tom ran a hand across his mouth. Boy, could I use a cigarette. Funny, I haven’t even thought about them in years.
«Look,» he said to the radio, «we might as well settle something right now. How many men are you going to let me have?»
«Don’t you think you’d better save that for now and get back to work?»
«It’s too damned cold out there. My fingers are still numb. You could have done a better job on insulating this suit.»
«There are a lot of things we could have done,» Jason said, «if we had the material.»
«How about the expedition? How many men can I have?»
«As many as you can get,» the radio voice answered. «I promised I won’t stand in your way once the satellite is finished and operating.»
«Won’t stand in my way,» Tom repeated. «That means you won’t encourage anyone, either.»
Jason’s voice rose a trifle. «I can’t encourage my people to go out and risk their lives just because you want to poke around some radioactive slag heaps!»
«You promised that if I put the satellite together and got back alive, I could investigate the cities. That was our deal.»
«That’s right. You can. And anyone foolish enough to accompany you can follow along.»
«Jason, you know I need at least twenty-five armed men to venture out of the settlement …»
«Then you admit it’s dangerous!» the radio voice crackled.
«Sure, if we meet a robber band. You’ve sent out enough foraging groups to know that. And we’ll be travelling hundreds of miles. But it’s not dangerous for the reasons you’ve been circulating … radioactivity and disease germs and that nonsense. There’s no danger that one of your own foraging groups couldn’t handle. I came through the cities last year alone, and I made it.»
