<p>"ALL ABOARD!"</p>
<p>A metallic voice rasped over the loud-speakers and echoed through the
lofty marble and aluminum concourse of the New Chicago Monorail
Terminal. "Atom City express on Track Seven! Space Academy first stop!
Passengers for Space Academy will please take seats in the first six
cars!"</p>
<p>As the crowd of people waiting in the concourse surged through the gate
leading to Track Seven, three boys in the royal-blue uniforms of the
Space Cadet Corps slowly picked up their plastic space bags and joined
the mass of travelers.</p>
<p>Wearily, they drifted with the crowd and stepped on the slidestairs
leading down to the monorail platform. In the lead, Tom Corbett, the
command cadet of the unit, a tall, curly-haired boy of eighteen,
slouched against the handrail and looked back at his two unit-mates,
Roger Manning and Astro. Manning, a slender cadet, with close-cropped
blond hair, was yawning and blinking his eyes sleepily, while Astro, the
third member of the unit, a head taller than either of his unit-mates
and fifty pounds heavier, stood flat-footed on the step, eyes closed,
his giant bulk swaying slightly with the motion of the slidestairs.</p>
<p>"Huh! A real snappy unit!" Tom muttered to himself.</p>
<p>"Hmmm? What?" Roger blinked and stared bleary-eyed at Tom.</p>
<p>"Nothing, Roger," Tom replied. "I only hope you guys can stay awake long
enough to get on the monorail."</p>
<p>"It's your own fault, Tom," rumbled Astro in his bull-like voice. "If
your family hadn't thrown so many parties for us while we were on leave,
we'd have had more sleep."</p>
<p>"I didn't hear any complaints then," snorted Tom. "Just get into the car
before you cork off, will you? I'm in no shape to carry you."</p>
<p>Seconds later, the slidestairs deposited the three boys on the platform
and they slowly made their way through the crowd toward the forward cars
of the monorail. Entering the third car, they found three seats together
and collapsed into their luxurious softness.</p>
<p>"Oh, brother!" Tom groaned as he curled himself into the cushions, "I'm
going to sleep all the way to the Academy."</p>
<p>"I'm asleep already," mumbled Roger, his voice muffled by his cap pulled
low over his face.</p>
<p>Suddenly Astro sat bolt upright. "I'm hungry!" he announced.</p>
<p>"Oh, no!" moaned Tom.</p>
<p>"Why, you overgrown Venusian ape, Mrs. Corbett gave you dinner less than
an hour ago!" Roger complained. "Steak, French fries, beans, corn, pie,
ice cream...."</p>
<p>"Two helpings," chimed in Tom.</p>
<p>"And now you're hungry!" Roger was incredulous.</p>
<p>"Can't help it," calmly answered Astro. "I'm a big guy, that's all." He
began digging through his space bag for an apple Mrs. Corbett had
thoughtfully provided.</p>
<p>Tom finally stirred and sat up. He had learned a long time ago the
futility of trying to deny Astro's Gargantuan appetite. "There's a
dining car on this section of the monorail, Astro," he said, slapping a
crumpled mass of credits into the Venusian's hamlike hand. "Here. Have
yourself a good time." He slumped back in his seat and closed his eyes.</p>
<p>"Yeah," growled Roger, "and when you come back, don't make any noise!"</p>
<p>Astro smiled. He got up carefully and climbed over his two sleeping
mates. Standing in the aisle, he counted the credits Tom had given him
and turned to the front of the car. Suddenly a heavy voice growled
behind him.</p>
<p>"One side, spaceboy!"</p>
<p>A hand grabbed him by the shoulder and pushed him to one side. Caught
off balance, Astro fell back on his sleeping unit-mates.</p>
<p>"Hey! What th—" stuttered Astro as he sprawled on top of his friends.
The two sleepy cadets came up howling.</p>
<p>"Astro! What in blazes do you think you're doing?" roared Tom.</p>
<p>"Why, you space-brained idiot," yelled Roger, "I ought to lay one on
your chin!"</p>
<p>There was a tangle of arms and legs and finally the three cadets
struggled to their feet. Astro turned to see who had pushed him.</p>
<p>Two men standing at the end of the car grinned back at him.</p>
<p>"It was those two guys at the end of the car," explained Astro. "They
pushed me!" He lumbered toward them, followed by Tom and Roger.</p>
<p>Stopping squarely in front of them, he demanded, "What's the big idea?"</p>
<p>"Go back to your beauty rest, spaceboy!" jeered the heavier of the two
men and turned to his companion, adding with a snarl, "How do you like
his nerve? We not only have to pay taxes to support these lazy kids and
teach them how to be spacemen, but they're loud-mouthed and sassy on top
of it!"</p>
<p>The other man, smaller and rat-faced, laughed. "Yeah, we oughta report
them to their little soldier bosses at Space Academy."</p>
<p>Astro suddenly balled his fists and stepped forward, but Tom grabbed his
arm and pulled him back while Roger eased himself between his mates and
the two grinning men.</p>
<p>"You know, Tom," he drawled, looking the heavier of the two right in the
eye, "the only thing I don't like about being a Space Cadet is having to
be polite to <i>all</i> the people, including the space crawlers!"</p>
<p>"Why, you little punk," sneered the bigger man, "I oughta wipe up the
deck with you!"</p>
<p>Roger smiled thinly. "Don't try it, mister. You wouldn't know what hit
you!"</p>
<p>"Come on, Wallace," said the smaller man. "Leave 'em alone and let's
go."</p>
<p>Astro took another step forward and roared, "Blast off. Both of you!"</p>
<p>The two men turned quickly and disappeared through the door leading to
the next monorail car.</p>
<p>The three cadets turned and headed back down the aisle to their seats.</p>
<p>"Let's get some sleep," said Tom. "We better be in good shape for that
new assignment when we hit the Academy. No telling what it'll be, where
we'll go, or worse yet, when we'll blast off. And I, for one, want to
have a good night's rest under my belt."</p>
<p>"Yeah," agreed Roger, settling himself into the cushions once more.
"Wonder what the orders will be. Got any ideas, Tom?"</p>
<p>"No idea at all, Roger," answered Tom. "The audiogram just said report
back to the Academy immediately for assignment."</p>
<p>"Hey, Astro!" exclaimed Roger, seeing the Venusian climb back into his
seat. "Aren't you going to eat?"</p>
<p>"I'm not hungry any more," grunted Astro. "Those guys made me lose my
appetite."</p>
<p>Tom looked at Roger and winked. "Maybe we'd better tell Captain Strong
about this, Roger."</p>
<p>"Why?"</p>
<p>"Get Astro mad enough and he won't want to eat. The Academy can cut down
on its food bills."</p>
<p>"Ah, rocket off, you guys," growled Astro sleepily.</p>
<p>Tom and Roger smiled at each other, closed their eyes, and in a moment
the three cadets of the Polaris unit were sound asleep.</p>

<hr style="width: 45%;" />
<p>Suspended from a single gleaming rail that stretched across the western
plains like an endless silver ribbon, the monorail express hurtled
through the early dawn speeding its passengers to their destination. As
the gleaming line of streamlined cars crossed the newly developed
grazing lands that had once been the great American desert, Tom Corbett
stirred from a deep sleep. The slanting rays of the morning sun were
shining in his eyes. Tom yawned, stretched, and turned to the viewport
to watch the scenery flash past. Looming up over the flat grassy plains
ahead, he could see a huge bluish mountain range, its many peaks covered
with ever-present snow. In a few moments Tom knew the train would rocket
through a tunnel and then on the other side, in the center of a deep,
wide valley, he would see Space Academy, the university of the planets
and headquarters of the great Solar Guard.</p>
<p>He reached over and shook Roger and Astro, calling, "All right,
spacemen, time to hit the deck!"</p>
<p>"Uh? Ah-ummmh!" groaned Roger.</p>
<p>"Ahhhoooohhhhhh!" yawned Astro. Standing up, he stretched and touched
the top of the monorail car.</p>
<p>"Let's get washed before the other passengers wake up," said Tom, and
headed for the morning room. Astro and Roger followed, dragging their
feet and rubbing their eyes.</p>
<p>Five minutes later, as the sleek monorail whistled into the tunnel
beneath the mountain range, the boys of the <i>Polaris</i> unit returned to
their seats.</p>
<p>"Back to the old grind," sighed Roger. "Drills, maneuvers, books,
lectures. The same routine, day in day out."</p>
<p>"Maybe not," said Tom. "Remember, the order for us to report back was
signed by Commander Walters, not the cadet supervisor of leaves. I think
that means something special."</p>
<p>Suddenly the monorail roared out of the tunnel and into brilliant
early-morning sun again.</p>
<p>The three cadets turned quickly, their eyes sweeping the valley for the
first sight of the shining Tower of Galileo.</p>
<p>"There it is," said Tom, pointing toward a towering crystal building
reflecting the morning light. "We'll be there in a minute."</p>
<p>Even as Tom spoke, the speed of the monorail slackened as it eased past
a few gleaming structures of aluminum and concrete. Presently the white
platform of the Academy station drifted past the viewport and all
forward motion stopped. The doors opened and the three boys hurried to
the exit.</p>
<p>All around the cadets, men and women in the vari-colored uniforms of the
Solar Guard hurried through the station. The green of the Earthworm
cadets, first-year students of the Cadet Corps; the brilliant rich blue
of the senior cadets like the <i>Polaris</i> unit; the scarlet red of the
enlisted Solar Guard; and here and there, the black and gold of the
officers of the Solar Guard.</p>
<p>The three cadets hurried to the nearest slidewalk, a moving belt of
plastic that glided silently across the ground toward Space Academy. It
whisked them quickly past the few buildings nestled around the monorail
station and rounded a curve. The three cadets looked up together at the
gleaming Tower of Galileo. Made of pure Titan crystal, it soared above
the cluster of buildings that surrounded the grassy quadrangle and
dominated Space Academy like a translucent giant.</p>
<p>The cadets stepped off the slidewalk as it glided past the Tower
building and ran up the broad marble stair. At the huge main portal, Tom
stopped and looked back over the Academy grounds. All around him lay the
evidence of mankind's progress. It was the year 2353, when Earthman had
long since colonized the inner planets, Mars and Venus, and the three
large satellites, Moon of Earth, Ganymede of Jupiter, and Titan of
Saturn. It was the age of space travel; of the Solar Alliance, a unified
society of billions of people who lived in peace with one another,
though sprawled throughout the universe; and the Solar Guard, the might
of the Solar Alliance and the defender of interplanetary peace. All
these things Tom saw as he stood in the wide portal of the Tower
Building, flanked by Astro and Roger.</p>
<p>Turning into the Tower, the three cadets went directly to the office of
their unit commander. The training program at Space Academy consisted of
three cadets to a unit, with a Solar Guard officer as their teacher and
instructor. Steve Strong, captain in the Solar Guard, had been their
cadet instructor since the unit had been formed and he now smiled a
welcome as the cadets snapped to attention in front of his desk.</p>
<p>"<i>Polaris</i> unit reporting as ordered, sir," said Tom, handing over the
audiogram order he had received the day before.</p>
<p>"Thank you, Corbett," said Strong, taking the paper. "At ease."</p>
<p>The three boys relaxed and broke into wide grins as Strong rounded his
desk and shook hands with each of them.</p>
<p>"Glad to have you back, boys," he said. "Did you enjoy your leave?"</p>
<p>"And how, sir," replied Tom.</p>
<p>"Tom's mother showed us a whale of a good time," chimed in Roger.</p>
<p>"And how she can cook!" Astro licked his lips involuntarily.</p>
<p>"Well, I hope you had a good rest—" said Strong, but was suddenly
interrupted by the sound of a small bell. Behind his desk a small
teleceiver screen glowed into life to reveal the stern face of Commander
Walters, the commander of Space Academy.</p>
<p>Strong turned to the teleceiver and called, "Yes, Commander Walters?"</p>
<p>"Did the <i>Polaris</i> unit arrive yet, Steve?" asked the commander.</p>
<p>"Yes, sir," replied Strong. "They're here in my office now, sir."</p>
<p>"Good," said the commander with a smile. "I just received a report the
exposition will open sooner than expected. I suggest you brief the
cadets and raise ship as soon as possible."</p>
<p>"Very well, sir," answered Strong. The screen darkened and he turned
back to the cadets. "Looks like you got back just in time."</p>
<p>"What's up, sir?" asked Tom.</p>
<p>Strong returned to his chair and sat down. "I suppose you've all heard
about the Solar Exposition that opens on Venus next week?"</p>
<p>Tom's eyes lit up. "Have we! That's all the stereos and visunews and
teleceivers have been yacking about for weeks now."</p>
<p>"Well," said Strong with a smile, "we're going!"</p>
<p>The three cadets couldn't restrain themselves and burst out in a happy
shout. Then Roger calmed down enough to comment, "Sounds more like
another vacation than an assignment, sir."</p>
<p>"Hardly, Manning," replied Strong. "You see, every industry, society,
organization, and governmental agency is setting up exhibits at the
exposition to show the people what's taking place in their part of the
solar system. There'll also be an amusement section." Strong chuckled.
"I've seen pictures of some of the tricks and rides they've developed to
entertain the younger generation. Believe me, I'd rather take full
acceleration on a rocket ship than ride on any of them."</p>
<p>"But what will we do, sir?" asked Tom.</p>
<p>"Our job is very simple. We're to take the <i>Polaris</i> to the exposition
and land on the fairgrounds. When the fair opens, we show all the
visitors who are interested, everything about her."</p>
<p>"You mean we're going to be"—Roger swallowed—"guides?"</p>
<p>"That's right, Manning," said Strong. "You three will guide all visitors
through the <i>Polaris</i>."</p>
<p>"How long will we be there, sir?" asked Tom.</p>
<p>"A month or so, I guess. The <i>Polaris</i> will be the first Academy
exhibit. When you leave, another unit will replace you with their ship
and do the same thing."</p>
<p>"But—but—" stammered Astro, "what will we say to them? The visitors, I
mean?"</p>
<p>"Just answer all their questions, Astro. Also, make up a little speech
about the functions of your particular station."</p>
<p>Strong looked at his watch and rose to his feet. "It's getting late.
Check the <i>Polaris</i> over and stand by to raise ship in an hour."</p>
<p>"Yes, sir," said Tom.</p>
<p>The cadets came to attention, preparing to leave.</p>
<p>"One thing more! Don't get the idea that this is going to be a space
lark," said Strong. "It's very important for the people of the Solar
Alliance to know what kind of work we're doing here at the Academy. And
you three have been selected as representatives of the entire Cadet
Corps. So see that you conduct yourselves accordingly. All right,
dismissed!"</p>
<p>The three cadets saluted sharply and filed out of the room, their
skipper's final words ringing in their ears.</p>
<p>Fifteen minutes later, having packed the necessary gear for the extended
trip, the <i>Polaris</i> unit rode the slidewalk through the grassy
quadrangle and the cluster of Academy buildings, out toward the
spaceport. In the distance they could see the rocket cruiser <i>Polaris</i>,
poised on the launching ramp, her long silhouette outlined sharply
against the blue sky. Resting on her four stabilizer fins, her nose
pointed toward the stars, the ship looked like a giant projectile poised
and ready to blast its target.</p>
<p>"Look at her!" exclaimed Astro. "If she isn't the most beautiful ship in
the universe, I'll eat my hat."</p>
<p>"Don't see how you could," drawled Roger, "after the way you put away
Mrs. Corbett's pies!"</p>
<p>Tom laughed. "I'll tell you one thing, Roger," he said, pointing to the
ship, "I feel like that baby is as much my home as Mom's and Dad's house
back in New Chicago."</p>
<p>"All right, all right," said Roger. "Since we're all getting sloppy, I
have to admit that I'm glad to see that old thrust bucket too!"</p>
<p>Presently the three cadets were scrambling into the mighty spaceship,
and they went right to work, preparing for blast-off.</p>
<p>Quickly, with sure hands, each began a systematic check of his station.
On the power deck Astro, a former enlisted Solar Guardsman who had been
admitted to the Cadet Corps because of his engineering genius, stripped
to the waist and started working on the ship's massive atomic engines. A
heavy rocketman's belt of tools slung around his waist, he crawled
through the heart of the ship, adjusting a valve here, turning a screw
there, seeing that the reactant feeders were clean and clear to the
rocket firing chambers. And last of all he made sure the great rocket
firing chambers were secure and the heavy sheets of lead baffling in
place to protect him from deadly radioactivity.</p>
<p>On the radar bridge in the nose of the ship, Roger removed the delicate
astrogation prism from its housing and cleaned it with a soft cloth.
Replacing it carefully, he turned to the radar scanner, checking the
intricate wiring system and making sure that the range finders were in
good working order. He then turned his attention to the intercom.</p>
<p>"Radar bridge to control deck," he called. "Checking the intercom, Tom."</p>
<p>Immediately below, on the control deck, Tom turned away from the control
panel. "All clear here, Roger. Check with Astro."</p>
<p>"All clear on the power deck!" The big Venusian's voice boomed over the
loud-speaker. The intercom could be heard all over the ship unless the
many speakers were turned off individually.</p>
<p>Tom turned his attention back to the great control panel, and one by one
tested the banks of dials, gauges, and indicators that controlled the
rocket cruiser. Tom Corbett had wanted to be a space Cadet as long as he
could remember. After taking the entrance exams, he had been accepted
for the rigid training that would prepare him to enter the ranks of the
great Solar Guard. He had met his two unit-mates, Roger and Astro, on
his very first day at the Academy, and after a difficult beginning,
adjusting to each other's personalities and the discipline of the
Academy routine, the three boys had become steadfast friends.</p>
<p>As control-deck cadet and pilot, Tom was head of the unit,
second-in-command to Captain Strong. And while he could issue orders to
Astro and Roger and expect to be obeyed, the three cadets all spoke
their minds when it came to making difficult decisions. This had
solidified the three cadets into a fighting, experienced, dependable
unit.</p>
<p>Tom made a final check on the gravity generator and turned to the
intercom.</p>
<p>"All departments, report!" he called.</p>
<p>"Radar bridge checks in O.K.," replied Roger.</p>
<p>"Power deck checks in on the nose, Tom," reported Astro.</p>
<p>"Right! Stand by! We blast as soon as the skipper gets around."</p>
<p>Tom turned to the teleceiver and switched it on. The screen blurred and
then steadied into a view of the spaceport outside. Tom scanned the
launching ramp below, and, satisfied it was clear, he switched the
teleceiver to the spaceport traffic-control circuit.</p>
<p>"Rocket cruiser <i>Polaris</i> to spaceport control," he called. "Come in,
spaceport control. Request orbit clearance."</p>
<p>"Spaceport traffic control to <i>Polaris</i>," reported the traffic officer,
his face in focus on the teleceiver screen. "Your orbit has been cleared
for blast-off. Orbit number 3847—repeat, 3847—raise ship when ready!"</p>
<p>"Orbit 3847," repeated Tom. "End transmission!"</p>
<p>"End transmission," said the officer. Tom flipped off the teleceiver and
the officer's face disappeared.</p>
<p>At the rear of the control deck, Captain Strong suddenly stepped through
the hatch and dropped his black plastic space bag on the deck. Tom got
up and saluted sharply.</p>
<p>"<i>Polaris</i> ready to blast off, sir," he said. "Orbit cleared."</p>
<p>"Very well, Corbett," replied Strong, returning the salute. "Carry on!"</p>
<p>Tom turned back to the control board and flipped on the intercom.
"Control deck to power deck! Energize the cooling pumps!"</p>
<p>"Cooling pumps, aye!" said Astro.</p>
<p>From the power deck, the massive pumps began their whining roar. The
great ship shuddered under the pressure.</p>
<p>Tom watched the gauge that indicated the pressure control and then
called into the intercom.</p>
<p>"Radar bridge, do we have a clear trajectory?'</p>
<p>"All clear forward and up, Tom," reported Roger from the radar bridge.</p>
<p>"Strap in for blast-off!" bawled the curly-haired cadet.</p>
<p>Captain Strong took his place in the pilot's chair next to Tom and
strapping himself in snapped out, "Feed reactant!"</p>
<p>Spinning a small wheel at the side of the control panel, Tom reported,
"Feeders at D-9 rate, sir!"</p>
<p>Then, as the hiss of fuel pouring into the mighty engines of the ship
blended with the whine of the pumps, Tom snapped out a third order. "Cut
in take-off six yards!"</p>
<p>Receiving acknowledgment from below, he grasped the master blast-off
switch and watched the sweeping hand of the astral chronometer.</p>
<p>"Stand by to raise ship!" he yelled. "Blast off
minus—five—four—three—two—one—<i>zero</i>!"</p>
<p>He pulled the switch.</p>
<p>Slowly, the rockets blasting evenly, the giant ship lifted itself free
of the ground. Then, gaining speed, it began rocketing away from the
Earth. Like a giant shining bullet, the great spaceship blasted through
the dark void of space, her nose pointed to the distant misty planet of
Venus.</p>
<p>Once again Tom Corbett and his unit-mates had embarked on a mission for
the Solar Guard.</p>
