                   _He held the future of the world
                 in his numbed hands. And from 22,500
                    miles out, he made the gamble._

Tom woke slowly, his mind groping back through the hypnosis. He found
himself looking toward the observation port, staring at stars and
blackness.

_The first man in space_, he thought bitterly.

He unstrapped himself from the acceleration seat, feeling a little
wobbly in free fall.

_The hypnotic trance idea worked, all right._

The last thing Tom remembered was Arnoldsson putting him under, here
in the rocket's compartment, the old man's sad soft eyes and quiet
voice. Now 22,500 miles out, Tom was alone except for what Arnoldsson
had planted in his mind for post-hypnotic suggestion to recall. The
hypnosis had helped him pull through the blastoff unhurt and even
protected him against the vertigo of weightlessness.

_Yeah, it's a wonderful world_, Tom muttered acidly.

He got up from the seat cautiously, testing his coordination against
zero gravity. His magnetic boots held to the deck satisfactorily.

He was lean and wiry, in his early forties, with a sharp angular face
and dark, somber eyes. His hair had gone dead white years ago. He was
encased up to his neck in a semi-flexible space suit; they had squirmed
him into it Earth-side because there was no room in the cramped cabin
to put it on.

Tom glanced at the tiers of instrument consoles surrounding his
seat--no blinking red lights, everything operating normally. _As if I
could do anything about it if they went wrong._ Then he leaned toward
the observation port, straining for a glimpse of the satellite.

The satellite.

Five sealed packages floating within a three-hundred foot radius of
emptiness, circling the Earth like a cluster of moonlets. Five pieces
sent up in five robot rockets and placed in the same orbit, to wait for
a human intelligence to assemble them into a power-beaming satellite.

Five pieces orbiting Earth for almost eighteen years; waiting for
nearly eighteen years while down below men blasted themselves and their
cities and their machines into atoms and forgot the satellite endlessly
circling, waiting for its creators to breathe life into it.

_The hope of the world_, Tom thought. _And little Tommy Morris is
supposed to make it work ... and then fly home again._ He pushed
himself back into the seat. _Jason picked the wrong man._

       *       *       *       *       *

"Tom! Tom, can you hear me?"

He turned away from the port and flicked a switch on the radio console.

"Hello Ruth. I can hear you."

A hubbub of excitement crackled through the radio receiver, then the
girl's voice: "Are you all right? Is everything...."

"Everything's fine," Tom said flatly. He could picture the scene back
at the station--dozens of people clustered around the jury-rigged
radio, Ruth working the controls, trying hard to stay calm when it was
impossible to, brushing back that permanently displaced wisp of brown
hair that stubbornly fell over her forehead.

"Jason will be here in a minute," she said. "He's in the tracking
shack, helping to calculate your orbit."

       *       *       *       *       *

_Of course Jason will be here_, Tom thought. Aloud he said, "He needn't
bother. I can see the satellite packages; they're only a couple of
hundred yards from the ship."

Even through the radio he could sense the stir that went through them.

_Don't get your hopes up_, he warned silently. _Remember, I'm no
engineer. Engineers are too valuable to risk on this job. I'm just
a tool, a mindless screwdriver sent here to assemble this glorified
tinkertoy. I'm the muscle, Arnoldsson is the nerve link, and Jason is
the brain._

Abruptly, Jason's voice surged through the radio speaker, "We did it,
Tom! We did it!"

_No_, Tom thought, _you did it, Jason. This is all your show._

"You should be able to see the satellite components," Jason said. His
voice was excited yet controlled, and his comment had a ring of command
in it.

"I've already looked," Tom answered. "I can see them."

"Are they damaged?"

"Not as far as I can see. Of course, from this distance...."

"Yes, of course," Jason said. "You'd better get right outside and start
working on them. You've only got forty-eight hours worth of oxygen."

"Don't worry about me," Tom said into the radio. "Just remember your
end of the bargain."

"You'd better forget that until you get back here."

"I'm not forgetting anything."

"I mean you must concentrate on what you're doing up there if you
expect to get back alive."

"When I get back we're going to explore the bombed-out cities. You
promised that. It's the only reason I agreed to this."

Jason's voice stiffened. "My memory is quite as good as yours. We'll
discuss the expedition after you return. Now you're using up valuable
time ... and oxygen."

"Okay. I'm going outside."

Ruth's voice came back on: "Tom, remember to keep the ship's radio
open, or else your suit radio won't be able to reach us. And we're all
here ... Dr. Arnoldsson, Jason, the engineers ... if anything comes up,
we'll be right here to help you."

       *       *       *       *       *

Tom grinned mirthlessly. _Right here: 22,500 miles away._

"Tom?"

"Yes Ruth."

"Good luck," she said. "From all of us."

_Even Jason?_ he wanted to ask, but instead said merely, "Thanks."

He fitted the cumbersome helmet over his head and sealed it to the
joints on his suit. A touch of a button on the control panel pumped
the compartment's air into storage cylinders. Then Tom stood up and
unlocked the hatch directly over his seat.

Reaching for the handholds just outside the hatch, he pulled himself
through, and after a weightless comic ballet managed to plant his
magnetized boots on the skin of the ship. Then, standing, he looked
out at the universe.

Oddly, he felt none of the overpowering emotion he had once expected
of this moment. Grandeur, terror, awe--no, he was strangely calm.
The stars were only points of light on a dead-black background; the
Earth was a fat crescent patched with colors; the sun, through his
heavily-tinted visor, was like the pictures he had seen at planetarium
shows, years ago.

As he secured a lifeline to the grip beside the hatch, Tom thought that
he felt as though someone had stuck a reverse hypodermic into him and
drained away all his emotions.

Only then did he realize what had happened. Jason, the engineer,
the leader, the man who thought of everything, had made Arnoldsson
condition his mind for this. No gaping at the universe for the first
man in space, too much of a chance to take! There's a job to be done
and no time for human frailty or sentiment.

_Not even that_, Tom said to himself. _He wouldn't even allow me one
moment of human emotion._

But as he pushed away from the ship and floated ghost-like toward the
largest of the satellite packages, Tom twisted around for another look
at Earth.

_I wonder if she looked that way before the war?_

       *       *       *       *       *

Slowly, painfully, men had attempted to rebuild their civilization
after the war had exhausted itself. But of all the things destroyed by
the bombs and plagues, the most agonizing loss was man's sources of
energy.

The coal mines, the oil refineries, the electricity-generating plants,
the nuclear power piles ... all shattered into radioactive rubble.
There could be no return to any kind of organized society while men
had to scavenge for wood to warm themselves and to run their primitive
machines.

Then someone had remembered the satellite.

It had been designed, before the war, to collect solar energy and beam
it to a receiving station on Earth. The satellite packages had been
fired into a 24-hour orbit, circling the Earth over a fixed point on
the Equator. The receiving station, built on the southeastern coast
of the United States, saw the five units as a single second-magnitude
star, low on the horizon all year, every year.

Of course the packages wavered slightly in their orbits, but not enough
in eighteen years to spread very far apart. A man could still put them
together into a power-beaming satellite.

If he could get there.

And if they were not damaged.

And if he knew how to put them together.

Through months that stretched into years, over miles of radioactive
wilderness, on horseback, on carts, on foot, those who knew about the
satellite spread the word, carefully, secretly, to what was left of
North America's scientists and engineers. Gradually they trickled into
the once-abandoned settlement.

They elected a leader: Jason, the engineer, one of the few men who knew
anything about rockets to survive the war and the lunatic bands that
hunted down anyone suspected of being connected with pre-war science.

Jason's first act was to post guards around the settlement. Then he
organized the work of rebuilding the power-receiving station and a
man-carrying rocket.

They pieced together parts of a rocket and equipment that had been
damaged by the war. What they did not know, they learned. What they
did not have, they built or cannibalized from ruined equipment.

Jason sent armed foragers out for gasoline, charcoal and wood. They
built a ramshackle electricity generator. They planted crops and hunted
the small game in the local underbrush. A major celebration occurred
whenever a forager came back towing a stray cow or horse or goat.

They erected fences around the settlement, because more than once they
had to fight off the small armies of looters and anti-scientists that
still roved the countryside.

But finally they completed the rocket ... after exhausting almost every
scrap of material and every ounce of willpower.

Then they picked a pilot: Thomas H. Morris, age 41, former historian
and teacher. He had arrived a year before the completion of the rocket
after walking 1,300 miles to find the settlement; his purpose was to
organize some of the scientists and explore the bombed-out cities to
see what could be salvaged out of man's shattered heritage.

But Tom was ideal for the satellite job: the right size--five-six and
one-hundred thirty pounds; no dependents--wife and two sons dead of
radiation sickness. True, he had no technical background whatsoever;
but with Arnoldsson's hypnotic conditioning he could be taught all that
it was necessary for him to know ... maybe.

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 girl 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 here 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."

       *       *       *       *       *

Tom waited for a reply from the radio, but only the hissing and
crackling of electrical disturbances answered him.

"Jason, those cities hold what's left of a world-wide civilization. We
can't begin to rebuild unless we reopen that knowledge. We need it, we
need it desperately!"

"It's either destroyed or radioactive, and to think anything else is
self-delusion. Besides, we have enough intelligence right here at the
settlement to build a new civilization, better than the old one, once
the satellite is ready."

"But you don't!" Tom shouted. "You poor damned fool, you don't even
realize how much you don't know."

"This is a waste of time," Jason snapped. "Get outside and finish your
work."

"I'm still cold, dammit," Tom said. He glanced at the thermometer on
the control console. "Jason! _It's below freezing in here!_"

"What?"

"The heating unit isn't working at all!"

"Impossible. You must have turned it off instead of on."

"I can read, dammit! It's turned as high as it'll go...."

"What's the internal thermometer reading?"

Tom looked. "Barely thirty ... and it's still going down."

"Hold on, I'll wake Arnoldsson and the electrical engineers."

Silence. Tom stared at the inanimate radio which gave off only the
whines and scratches of lightning and sun and stars, all far distant
from him. For all his senses could tell him, he was the last living
thing in the universe.

_Sure, call a conference_, Tom thought. _How much more work is there
to be done? About twenty-four hours, he said. Another day. And another
full night. Another night, this time with no heat. And maybe no oxygen,
either. The heaters must have been working tonight until I pushed them
up to full power. Something must have blown out. Maybe it's just a
broken wire. I could fix that if they tell me how. But if it's not ...
no heat tomorrow night, no heat at all._

Then Arnoldsson's voice floated up through the radio speaker: soft,
friendly, calm, soothing....

       *       *       *       *       *

The next thing Tom knew he was putting on his helmet. Sunlight was
lancing through the tinted observation port and the ship was noticeably
warmer.

"What happened?" he mumbled through the dissolving haze of hypnosis.

"It's all right, Tom." Ruth's voice. "Dr. Arnoldsson put you under and
had you check the ship's wiring. Now he and Jason and the engineers
are figuring out what to do. They said it's nothing to worry about ...
they'll have everything figured out in a couple of hours."

"And I'm to work on the satellite until they're ready?"

"Yes."

"Don't call us, we'll call you."

"What?"

"Nothing."

"It's all right, Tom. Don't worry."

"Sure Ruth, I'm not worried." _That makes us both liars._

He worked mechanically, handling the unfamiliar machinery with the
engineers' knowledge through Arnoldsson's hypnotic communication.

_Just like the pictures they used to show of nuclear engineers handling
radioactive materials with remotely-controlled mechanical hands from
behind a concrete wall. I'm only a pair of hands, a couple of opposed
thumbs, a fortunate mutation of a self-conscious simian ... but, God,
why don't they call? She said it wasn't anything big. Just the wiring,
probably. Then why don't they call?_

He tried to work without thinking about anything, but he couldn't
force his mind into stillness.

_Even if I can fix the heaters, even if I don't freeze to death, I
might run out of oxygen. And how am I going to land the ship? The
takeoff was automatic, but even Jason and Arnoldsson can't make a pilot
out of me...._

"Tom?" Jason's voice.

"Yes!" He jerked to attention and floated free of the satellite.

"We've ... eh, checked what you told us about the ship's electrical
system while Arnoldsson had you under the hypnotic trance...."

"And?"

"Well ... it, eh, looks as though one of the batteries gave out. The
batteries feed all the ship's lights, heat, and electrical power ...
with one of them out, you don't have enough power to run the heaters."

"There's no way to fix it?"

"Not unless you cut out something else. And you need everything
else ... the radio, the controls, the oxygen pumps...."

"What about the lights? I don't need them, I've got the lamp on my suit
helmet."

"They don't take as much power as the heaters do. It wouldn't help at
all."

Tom twisted weightlessly and stared back at Earth. "Well just what the
hell am I supposed to _do_?"

"Don't get excited," Jason's voice grated in his earphones. "We've
calculated it all out. According to our figures, your suit will store
enough heat during the day to last the night...."

"I nearly froze to death last night and the ship was heated most of the
time!"

"It will get cold," Jason's voice answered calmly, "but you should be
able to make it. Your own body warmth will be stored by the suit's
insulation, and that will help somewhat. But you must not open the suit
all night, not even to take off your helmet."

"And the oxygen?"

"You can take all the replacement cylinders from the ship and keep
them at the satellite. The time you save by not having to go back and
forth to the ship for fresh oxygen will give you about an hour's extra
margin. You should be able to make it."

Tom nodded. "And of course I'm expected to work on the satellite right
through the night."

"It will help you keep your mind off the cold. If we see that you're
not going to make it--either because of the cold or the oxygen--we'll
warn you and you can return to the settlement."

"Suppose I have enough oxygen to just finish the satellite, but if I
do, I won't have enough to fly home. Will you warn me then?"

"Don't be dramatic."

"Go to hell."

"Dr. Arnoldsson said he could put you under," Jason continued
unemotionally, "but he thinks you might freeze once your conscious mind
went asleep."

"You've figured out all the details," Tom muttered. "All I have to do
is put your damned satellite together without freezing to death and
then fly 22,500 miles back home before my air runs out. Simple."

He glanced at the sun, still glaring bright even through his tinted
visor. It was nearly on the edge of the Earth-disk.

"All right," Tom said, "I'm going into the ship now for some pills;
it's nearly sunset."

       *       *       *       *       *

Cold. Dark and so cold that numbers lost their meaning. Paralyzing
cold, seeping in through the suit while you worked, crawling up your
limbs until you could hardly move. The whole universe hung up in the
sky and looked down on the small cold figure of a man struggling
blindly with machinery he could not understand.

Dark. Dark and cold.

Ruth stayed on the radio as long as Jason would allow her, talking to
Tom, keeping the link with life and warmth. But finally Jason took
over, and the radio went silent.

_So don't talk_, Tom growled silently, _I can keep warm just by hating
you, Jason._

He worked through the frigid night, struggling ant-like with huge
pieces of equipment. Slowly he assembled the big parabolic mirror, the
sighting mechanism and the atomic convertor. With dreamy motions he
started connecting the intricate wiring systems.

And all the while he raged at himself: _Why? Why did it have to be this
way? Why me? Why did I agree to do this? I knew I'd never live through
it; why did I do it?_

He retraced the days of his life: the preparations for the flight, the
arguments with Jason over exploring the cities, his trek from Chicago
to the settlement, the aimless years after the radiation death of his
two boys and Marjorie, his wife.

Marjorie and the boys, lying sick month after month, dying one after
the other in a cancerous agony while he stood by helplessly in the
ruins of what had been their home.

_No!_ His mind warned him. _Don't think of that. Not that. Think of
Jason, Jason who prevents you from doing the one thing you want, who
is taking your life from you; Jason, the peerless leader; Jason, who's
afraid of the cities. Why? Why is he afraid of the cities? That's the
hub of everything down there. Why does Jason fear the cities?_

       *       *       *       *       *

It wasn't until he finished connecting the satellite's last unit--the
sighting mechanism--that Tom realized the answer.

One answer. And everything fell into place.

Everything ... except what Tom Morris was going to do about it.

Tom squinted through the twin telescopes of the sighting mechanism
again, then pushed away and floated free, staring at the Earth bathed
in pale moonlight.

_What do I do now?_ For an instant he was close to panic, but he forced
it down. _Think_, he said to himself. _You're supposed to be a Homo
Sapiens ... use that brain. Think!_

The long night ended. The sun swung around from behind the bulk of
Earth. Tom looked at it as he felt its warmth penetrating the insulated
suit, and he knew it was the last time he would see the sun. He felt no
more anger--even his hatred of Jason was drained out of him now. In its
place was a sense of--finality.

He spoke into his helmet mike. "Jason."

"He is in conference with the astronomers." Dr. Arnoldsson's voice.

"Get him for me, please."

A few minutes of silence, broken only by the star-whisperings in his
earphones.

Jason's voice was carefully modulated. "Tom, you made it."

"I made it. And the satellite's finished."

"It's finished? Good. Now, what we have to do...."

"Wait," Tom interrupted. "It's finished but it's useless."

"What?"

Tom twisted around to look at the completed satellite, its oddly-angled
framework and bulbous machinery glinting fiercely in the newly-risen
sun. "After I finished it I looked through the sighting mechanism to
make certain the satellite's transmitters were correctly aimed at the
settlement. Nobody told me to, but nobody said not to, either, so I
looked. It's a simple mechanism.... The transmitters are pointed smack
in the middle of Hudson's Bay."

"You're sure?"

"Certainly."

"You can rotate the antennas...."

"I know. I tried it. I can turn them as far south as the Great Lakes."

A long pause.

"I was afraid of this," Jason's voice said evenly.

_I'll bet you were_, Tom answered to himself.

"You must have moved the satellite out of position while assembling its
components."

       *       *       *       *       *

"So my work here comes to nothing because the satellite's power beam
can't reach the settlement's receivers."

"Not ... not unless you use the ship ... to tow the satellite into the
proper orbital position," Jason stammered.

_You actually went through with it_, Tom thought. Aloud, he said, "But
if I use the ship's engine to tow the satellite, I won't have enough
fuel left to get back to Earth, will I?" _Not to mention oxygen._

A longer pause. "No."

"I have two questions, Jason. I think I know the answers to them both
but I'll ask you anyway. One. You knew this would happen, didn't you?"

"What do you mean?"

"You've calculated this insane business down to the last drop of
sweat," Tom growled. "You knew that I'd knock the satellite out of
position while I was working on it, and the only way to get it back in
the right orbit would be for me to tow it back and strand myself up
here. This is a suicide mission, isn't it, Jason?"

"That's not true...."

"Don't bother defending yourself. I don't hate you anymore, Jason, I
understand you, dammit. You made our deal as much to get rid of me as
to get your precious satellite put together."

"No one can force you to tow the satellite...."

"Sure, I can leave it where it is and come back home. If I can fly this
ship, which I doubt. And what would I come back to? I left a world
without power. I'd return to a world without hope. And some dark night
one of your disappointed young goons would catch up with me ... and no
one would blame him, would they?"

Jason's voice was brittle. "You'll tow it into position?"

"After you answer my second question," Tom countered. "Why are you
afraid of the cities?"

"Afraid? I'm not afraid."

"Yes you are. Oh, you could use the hope of exploring the cities to
lure me up here on this suicide-job, but you knew I'd never be back
to claim my half of the bargain. You're afraid of the cities, and I
think I know why. You're afraid of the unknown quantity they represent,
distrustful of your own leadership when new problems arise...."

"We've worked for more than ten years to make this settlement what it
is," Jason fumed. "We fought and died to keep those marauding lunatics
from wrecking us. We are mankind's last hope! We can't afford to let
others in ... they're not scientists, they wouldn't understand, they'd
ruin everything."

"Mankind's last hope, terrified of men." Tom was suddenly tired, weary
of the whole struggle. But there was something he had to tell them.

"Listen Jason," he said. "The walls you've built around the
settlement weren't meant to keep you from going outside. You're not
a self-sufficient little community ... you're cut off from mankind's
memory, from his dreams, from his ambitions. You can't even start to
rebuild a civilization--and if you do try, don't you think the people
outside will learn about it? Don't you think they've got a right to
share in whatever progress the settlement makes? And if you don't let
them, don't you realize that they'll destroy the settlement?"

Silence.

       *       *       *       *       *

"I'm a historian," Tom continued, "and I know that a civilization
can't exist in a vacuum. If outsiders don't conquer it, it'll rot from
within. It's happened to Babylonia, Greece, Rome, China, even. Over and
again. The Soviets built an Iron Curtain around themselves, and wiped
themselves out because of it.

"Don't you see, Jason? There are only two types of animals on this
planet: the gamblers and the extinct. It won't be easy to live with
the outsiders, there'll be problems of every type. But the alternative
is decay and destruction. _You've got to take the chance, if you don't
you're dead._"

A long silence. Finally Jason said, "You've only got about a
half-hour's worth of oxygen left. Will you tow the satellite into the
proper position?"

Tom stared at the planet unseeingly. "Yes," he mumbled.

"I'll have to check some calculations with the astronomers," Jason's
voice buzzed flatly in his earphones.

A background murmur, scarcely audible over the crackling static.

Then Ruth's voice broke through, "Tom, Tom, you can't do this! You
won't be able to get back!"

"I know," he said, as he started pulling his way along the lifeline
back to the ship.

"_No!_ Come back, Tom, please. Come back. Forget the satellite. Come
back and explore the cities. I'll go with you. Please. Don't die, Tom,
please don't die...."

"Ruth, Ruth, you're too young to cry over me. I'll be all right, don't
worry."

"No, it isn't fair."

"It never is," Tom said. "Listen, Ruth. I've been dead a long time.
Since the bombs fell, I guess. My world died then and I died with it.
When I came to the settlement, when I agreed to make this flight, I
think we all knew I'd never return, even if we wouldn't admit it to
ourselves. But I'm just one man, Ruth, one small part of the story. The
story goes on, with or without me. There's tomorrow ... your tomorrow.
I've got no place in it, but it belongs to you. So don't waste your
time crying over a man who died eighteen years ago."

He snapped off his suit radio and went the rest of the way to the ship
in silence. After locking the hatch and pumping air back into the
cabin, he took off his helmet.

_Good clean canned air_, Tom said to himself. _Too bad it won't last
longer._

       *       *       *       *       *

He sat down and flicked a switch on the radio console. "All right, do
you have those calculations ready?"

"In a few moments...." Arnoldsson's voice.

Ten minutes later Tom re-emerged from the ship and made his ghost-like
way back to the satellite's sighting mechanism. He checked the
artificial moon's position, then went back to the ship.

"On course," he said to the radio. "The transmitters are pointing a
little northwest of Philadelphia."

"Good," Arnoldsson's voice answered. "Now, your next blast should be
three seconds' duration in the same direction...."

"No," Tom said, "I've gone as far as I'm going to."

"What?"

"I'm not moving the satellite any farther."

"But you still have not enough fuel to return to Earth. Why are you
stopping here?"

"I'm not coming back," Tom answered. "But I'm not going to beam the
satellite's power to the settlement, either."

"_What are you trying to pull?_" Jason's voice. Furious. Panicky.

"It's simple, Jason. If you want the satellite's power, you can
dismantle the settlement and carry it to Pennsylvania. The transmitters
are aimed at some good farming country, and within miles of a city
that's still half-intact."

"You're insane!"

"Not at all. We're keeping our deal, Jason. I'm giving you the
satellite's power, and you're going to allow exploration of the cities.
You won't be able to prevent your people from rummaging through the
cities now; and you won't be able to keep the outsiders from joining
you, not once you get out from behind your own fences."

"You can't do this! You...."

Tom snapped off the radio. He looked at it for a second or two, then
smashed a heavy-booted foot against the console. Glass and metal
crashed satisfactorily.

_Okay_, Tom thought, _it's done. Maybe Jason's right and I'm crazy,
but we'll never know now. In a year or so they'll be set up outside
Philadelphia, and a lot better for it, I'm forcing them to take the
long way back, but it's a better way. The only way, maybe._

He leaned back in the seat and stared out the observation port at the
completed satellite. Already it was taking in solar energy and beaming
it Earthward.

_In ten years they'll send another ship up here to check the gadget and
make sure everything's okay. Maybe they'll be able to do it in five
years. Makes no difference. I'll still be here._
