<p>"Got everything we need?" asked Tom.</p>
<p>"Everything we'll need—and about all we can safely
carry without weighing ourselves down too much," answered
Roger. "Enough food for a week, the rest of the
Martian water, space goggles to protect our eyes from
the sun and emergency lights for each of us."</p>
<p>"Not much to walk a hundred and fifty miles on,"
offered Astro. "Too bad the sand got in the galley and
messed up the rest of that good food."</p>
<p>"We'll have plenty to get us by—if my calculations
are right," said Tom. "One hundred and fifty-four miles
to be exact."</p>
<p>"<i>Exact</i> only as far as my sun sight told me," said
Roger.</p>
<p>"Do you think it's right?" asked Tom.</p>
<p>"I'll answer you this way," Roger replied. "I took
that sight six times in a half hour and got a mean average
on all of them that came out within a few miles of
each other. If I'm wrong, I'm very wrong, but if I'm
right, we're within three to five miles of the position I
gave you."</p>
<p>"That's good enough for me," said Astro. "If we're
going out there"—he pointed toward the desert—"instead
of sitting around here waiting for Strong or someone
to show up, then I'd just as soon go now!"
<span class="pagenum"><SPAN name="Page_194" id="Page_194"></SPAN></span></p>
<p>"Wait a minute, fellas. Let's get this straight," said
Tom. "We're all agreed that the odds on Captain
Strong's showing up here before our water runs out
are too great to risk it, and that we'll try to reach the
nearest canal. The most important thing in this place
is water. If we stay and the water we have runs out,
we're done for. If we go, we might not reach the canal—and
the chance of being spotted in the desert is even
smaller than if we wait here at the ship." He paused.
"So we move on?" He looked at the others. Astro
nodded and looked at Roger, who bobbed his head in
agreement.</p>
<p>"O.K., then," said Tom, "it's settled. We'll move at
night when it's cool, and try to rest during the day
when it's the hottest."</p>
<p>Roger looked up at the blazing white sphere in the
pale-blue sky that burned down relentlessly. "I figure
we have about six hours before she drops for the day,"
he said.</p>
<p>"Then let's go back inside the ship and get some
rest," he said.</p>
<p>Without another word, the three cadets climbed
back inside the ship and made places for themselves
amid the littered deck of the control room. A hot wind
blew out of the New Sahara through the open port like
a breath of fire. Stripped to their shorts, the three boys
lay around the deck unable to sleep, each thinking
quietly about the task ahead, each remembering stories
of the early pioneers who first reached Mars. In the
mad rush for the uranium-yielding pitchblende, they
had swarmed over the deserts toward the dwarf
mountains by the thousands. Greedy, thinking only of
the fortunes that could be torn from the rugged little
mountains, they had come unprepared for the heat of
the Martian deserts and nine out of ten had never returned.
<span class="pagenum"><SPAN name="Page_195" id="Page_195"></SPAN></span></p>
<p>Each boy thought, too, of the dangers they had just
faced. This new danger was different. This was something
that couldn't be defeated with an idea or a sudden
lucky break. This danger was ever present—a fight
against nature, man against the elements on an alien
planet. It was a battle of endurance that would wring
the last drop of moisture mercilessly from the body, until
it became a dry, brittle husk.</p>
<p>"Getting pretty close to sundown," said Tom finally.
He stood beside the open port and shielded his eyes
from the glare of the sun, now slowly sinking below the
Martian horizon.</p>
<p>"I guess we'd better get going," said Roger. "All set,
Astro?"</p>
<p>"Ready, Roger," answered the Venusian.</p>
<p>The three boys dressed and arranged the food packs
on their backs. Tom carried the remainder of the Martian
water, two quart plastic containers, and a six-yard
square of space cloth, an extremely durable flyweight
fabric that would serve as protection from the sun during
the rest stop of the day. Roger and Astro carried
the food in compact packs on their backs. Each boy
wore a makeshift hat of space cloth, along with space
goggles, a clear sheet of colored plastic that fitted
snugly across the face. All three carried emergency
lights salvaged from the wrecked ship.</p>
<p>Tom walked out away from the ship several hundred
yards and studied his pocket compass. He held it
steady for a moment, watching the needle swing
around. He turned and walked slowly still watching
the needle of the compass. He waited for it to steady
again, then turned back to Roger and Astro who stood
watching from the window port.</p>
<p>"This is the way." Tom pointed away from the ship.
"Three degrees south of east, one hundred and fifty-four
<span class="pagenum"><SPAN name="Page_196" id="Page_196"></SPAN></span>miles away, if everything is correct, should bring
us smack on top of a major canal."</p>
<p>"So long, <i>Lady Venus</i>," said Astro, as he left the ship.</p>
<p>"Don't think it hasn't been fun," added Roger, "because
it hasn't!"</p>
<p>Astro fell in behind Roger, who in turn followed
Tom who walked some ten feet ahead. A light breeze
sprang up and blew across the surface of the powdery
sand. Ten minutes later, when they stopped to adjust
their shoulder packs, they looked back. The breeze had
obliterated their tracks and the mountain of sand covering
the spaceship appeared to be no different from any
of the other small dunes on the desert. The New Sahara
desert of Mars had claimed another Earth-ship victim.</p>
<p>"If we can't see the <i>Lady Venus</i> standing still, and
knowing where to look," said Astro, "how could a man
in a rocket scout ever find it?"</p>
<p>"He wouldn't," said Roger flatly. "And when the
water ran out, we'd just be sitting there."</p>
<p>"We're losing time," said Tom. "Let's move." He
lengthened his stride through the soft sand that sucked
at his high space boots and faced the already dimming
horizon. The light breeze felt good on his face.</p>
<hr>
<p>The three cadets had no fear of running into anything
in their march through the darkness across the
shifting sands. And only an occasional flash of the
emergency light to check the compass was necessary
to keep them moving in the right direction.</p>
<p>There wasn't much talk. There wasn't much to talk
about. About nine o'clock the boys stopped and opened
one of the containers of food and ate a quick meal of
sandwiches. This was followed by a carefully measured
ounce of water, and fifteen minutes later they resumed
their march across the New Sahara.
<span class="pagenum"><SPAN name="Page_197" id="Page_197"></SPAN></span></p>
<p>About ten o'clock, Deimos, one of the small twin
moons of Mars, swung up overhead, washing the desert
with a pale cold light. By morning, when the cherry-red
sun broke the line of the horizon, Tom estimated
that they had walked about twenty miles.</p>
<p>"Think we ought to camp here?" asked Astro.</p>
<p>"If you can show me a better spot," said Roger with
a laugh, "I'll be happy to use it!" He swung his arm in
a wide circle, indicating a wasteland of sand that
spread as far as the eyes could see.</p>
<p>"I could go for another hour or so," said Astro, "before
it gets too hot."</p>
<p>"And wait for the heat to reach the top of the thermometer?
Uh-huh, not me," said Roger. "I'll take as
much sleep as I can get now—while it's still a little
cool."</p>
<p>"Roger's right," said Tom. "We'd better take it easy
now. We won't be able to get much sleep after noon."</p>
<p>"What do we do from noon until evening?" asked
Astro.</p>
<p>"Aside from just sitting under this hunk of space
cloth, I guess we'll come as close to being roasted alive
as a human can get."</p>
<p>"You want to eat now?" asked Astro.</p>
<p>Tom and Roger laughed. "I'm not hungry, but you
go ahead," said Tom. "I know that appetite of yours
won't wait."</p>
<p>"I'm not too hungry either," said Roger. "Go ahead,
you clobber-headed juice jockey."</p>
<p>Astro grinned sheepishly, and opening one of the
containers of food, quickly wolfed down a breakfast of
smoked Venusian fatfish.</p>
<p>Tom and Roger began spreading the space cloth on
the sand that was already hot to the touch. Anchoring
the four corners in the sand with the emergency lights
and one of Tom's boots, they propped up the center with
<span class="pagenum"><SPAN name="Page_198" id="Page_198"></SPAN></span>the food packs, one on top of the other. A crude tent
was the result and both boys crawled in under, sprawling
on the sand. Astro finished eating, lay down beside
his two unit-mates, and in a moment the three cadets
were sound asleep.</p>
<p>The sun climbed steadily over the desert while the
<i>Polaris</i> unit slept. With each hour, the heat of the desert
rose, climbing past the hundred mark, reaching one
hundred and twenty, then one hundred and thirty-five
degrees.</p>
<p>Tom woke up with a start. He felt as if he were inside
a blazing furnace. He rolled over and saw Astro
and Roger still asleep, sweat pouring off them in
small rivulets. He started to wake them, but decided
against it and just lay still under the thin sheet of space
cloth that protected him from the sun. As light as the
fabric square was, weighing no more than a pound,
under the intense heat of the sun it felt like a woolen
blanket where it touched him. Astro rolled over and
opened his eyes.</p>
<p>"What time is it, Tom?"</p>
<p>"Must be about noon. How do you feel?"</p>
<p>"I'm not sure yet. I had a dream." The big cadet
rubbed his eyes and wiped the sweat from his forehead.
"I dreamed I was being shoved into an oven—like
Hansel and Gretel in that old fairy tale."</p>
<p>"Personally," mumbled Roger, without opening his
eyes, "I'll take Hansel and Gretel. They might be a little
more tender."</p>
<p>"I could do with a drink," said Astro, looking at Tom.</p>
<p>Tom hesitated. He felt that as hot as it was, it would
get still hotter and there had to be strict control of the
remainder of the water.</p>
<p>"Try to hold out a little longer, Astro," said Tom.
"This heat hasn't really begun yet. You could drink the
whole thing and still want more."
<span class="pagenum"><SPAN name="Page_199" id="Page_199"></SPAN></span></p>
<p>"That's right, Astro," said Roger, sitting up. "Best
thing to do is just wet your tongue and lips a little.
Drinking won't do much good now."</p>
<p>"O.K. by me," said Astro. "Well, what do we do
now?"</p>
<p>"We sit here and we wait," answered Tom. He sat
up and held the space cloth up on his side.</p>
<p>"You get in the middle, Astro," suggested Roger.
"Your head is up higher than mine and Tom's. You can
be the tent pole under this big top."</p>
<p>Astro grunted and changed places with the smaller
cadet.</p>
<p>"Think there might be a breeze if we opened up one
side of this thing?" asked Roger.</p>
<p>"If there was a breeze," answered Tom, "it'd be so
hot, it'd be worse than what we've got inside."</p>
<p>"It sure is going to be a hot day," said Astro softly.</p>
<p>The thin fabric of the space cloth was enough to protect
them from the direct rays of the sun, but offered
very little protection against the heat. Soon the inside
of the tent was boiling under the relentless sun.</p>
<p>They sat far apart, their knees pulled up, heads
bowed. Once when the heat seemed unbearable, Tom
opened one side of the cloth in a desperate hope that
it might be a little cooler outside. A blast of hot air
entered the makeshift tent and he quickly closed the
opening.</p>
<p>About three o'clock Roger suddenly slipped backward
and lay sprawled on the sand.</p>
<p>Tom opened one of the containers of water and
dipped his shirttail into it. Astro watched him moisten
Roger's lips and wipe his temples. In a few moments
the cadet stirred and opened his eyes.</p>
<p>"I—I—don't know what happened," he said slowly.
"Everything started swimming and then went black."</p>
<p>"You fainted," said Tom simply.
<span class="pagenum"><SPAN name="Page_200" id="Page_200"></SPAN></span></p>
<p>"What time is it?" asked Astro.</p>
<p>"Sun should be dropping soon now, in another
couple of hours."</p>
<p>They were silent again. The sun continued its journey
across the sky and at last began to slip behind the
horizon. When the last red rays stretched across the
sandy desert, the three cadets folded back the space-cloth
covering and stood up. A soft evening breeze
sprang up, refreshing them a little, and though none of
them was hungry, each boy ate a light meal.</p>
<p>Tom opened the container of water again and measured
out about an ounce apiece.</p>
<p>"Moisten your tongue, and sip it slowly," ordered
Tom.</p>
<p>Roger and Astro took their share of the water and
dipped fingers in it, wiping their lips and eyelids. They
continued to do this until finally, no longer able to resist,
they took the precious water and swished it around
in their mouths before swallowing it.</p>
<p>They folded the space cloth, shouldered their packs,
and after Tom had checked the compass, started their
long march toward their plotted destination.</p>
<p>They had survived their first twenty-four hours in
the barren wastes of the New Sahara, with each boy
acutely aware that there was at least a week more of
the same in front of them. The sky blackened, and soon
after Deimos rose and started climbing across the
dark sky.
