<p>"The following ships in Squadron A will blast off immediately,"
roared Commander Walters over the teleceiver.
He looked up alertly from a chart before him
in the Academy spaceport control tower. He began to
name the ships. "<i>Capella</i>, orbital tangent—09834, <i>Arcturus</i>,
orbital tangent—09835, <i>Centauri</i>, orbital tangent—09836,
<i>Polaris</i>, orbital tangent—09837!"</p>
<p>Aboard the space cruiser <i>Polaris</i>, Tom Corbett
turned away from the control board. "That's us, sir,"
he said to Captain Strong.</p>
<p>"Very well, Corbett." The Solar Guard captain
walked to the ship's intercom and flipped on the switch.</p>
<p>"Astro, Roger, stand by!"</p>
<p>Astro and Roger reported in. Strong began to speak.
"The cadet corps has been divided into squadrons of
four ships each. We are command ship of Squadron A.
When we reach free-fall space, we are to proceed as a
group until eight hundred hours, when we are to open
sealed orders. Each of the other seven squadrons will
open their orders at the same time. Two of the squadrons
will then act as invaders while the remaining six
will be the defending fleet. It will be the invaders' job to
reach their objective and the defenders' job to stop
them."</p>
<p>"Spaceport control to rocket cruiser <i>Polaris</i>, your orbit
<span class="pagenum"><SPAN name="Page_121" id="Page_121"></SPAN></span>has been cleared for blast-off...." The voice of
Commander Walters interrupted Strong in his instructions
and he turned back to Tom.</p>
<p>"Take over, Corbett."</p>
<p>Tom turned to the teleceiver. "Rocket cruiser <i>Polaris</i>
to spaceport control."</p>
<p>" ... Blast off minus two—six hundred forty-eight...."</p>
<p>"I read you clear," said Tom. He clicked off the teleceiver
and turned back to the intercom. "Stand by to
raise ship! Control deck to radar deck. Do we have
clear trajectory forward and up, Roger?"</p>
<p>"All clear forward and up," replied Roger.</p>
<p>"Control deck to power deck ... energize the cooling
pumps!"</p>
<p>"Cooling pumps, aye," came from Astro.</p>
<p>The giant ship began to shudder as the mighty
pumps on the power deck started their build.</p>
<p>Tom strapped himself into the pilot's seat and began
checking the dials in front of him. Satisfied, he fastened
his eyes on the sweep hand of the time clock. Above
his head, the teleceiver screen brought him a clear
picture of the Academy spaceport. He watched the
giant cruisers take to the air one by one and rocket into
the vastness of space.</p>
<p>The clock hand reached the ten-second mark.</p>
<p>"Stand by to raise ship!" Tom called into the intercom.
The red hand moved steadily, inexorably. Tom
reached for the master switch.</p>
<p>"Blast off minus—five—four—three—two—one—<i>zero</i>!"</p>
<p>Tom threw the switch.</p>
<p>The great ship hovered above the ground for a few
moments. Then it heaved itself skyward, faster and
ever faster, pushing the Earthmen deep into their acceleration
cushions.<span class="pagenum"><SPAN name="Page_122" id="Page_122"></SPAN></span></p>
<p>Reaching free-fall space, Tom flipped on the artificial-gravity
generator. He felt its pull on his body, quickly
checked all the instruments and turned to Captain
Strong.</p>
<p>"Ship space-borne at six hundred fifty-three, sir."</p>
<p>"Very well, Corbett," replied Strong. "Check in with
the <i>Arcturus</i>, <i>Capella</i> and the <i>Centauri</i>, form up on
one another and assume a course that will bring you
back over Academy spaceport at eight hundred hours,
when we will open orders."</p>
<p>"Yes, sir," said Tom, turning back eagerly to the control
board.</p>
<p>For nearly two hours the four rocket ships of Squadron
A moved through space in a perfect arc, shaping
up for the 0800 deadline. Strong made use of the time
to check a new astrogation prism perfected by Dr.
Dale for use at hyperspace speeds. Tom rechecked his
instruments, then prepared hot tea and sandwiches in
the galley for his shipmates.</p>
<p>"This is what I call service," said Astro. He stood
stripped to the waist, a wide leather belt studded with
assorted wrenches of various shapes and sizes strapped
around his hips. In one hand he carried a wad of waste
cotton with which he continually polished the surfaces
of the atomic motors, while his eyes constantly
searched the many gauges in front of him for the slightest
sign of engine failure.</p>
<p>"Never mind bringing anything up to Manning. I'll
eat his share."</p>
<p>Astro had deliberately turned the intercom on so
Roger on the radar deck might hear. The response from
that corner was immediate and emphatic.</p>
<p>"Listen, you rocket-headed grease monkey," yelled
Roger. "If you so much as smell that grub, I'll come
down and feed you into the reactant chamber!"</p>
<p>Tom smiled at Astro and turned to the ladder leading
<span class="pagenum"><SPAN name="Page_123" id="Page_123"></SPAN></span>up from the power deck. Passing through the control
deck on the way to the radar bridge, he glanced at the
clock. It was ten minutes to eight.</p>
<p>"Only one thing I'm worried about, Corbett," said
Roger through a mouthful of sandwich.</p>
<p>"What's that?" asked Tom.</p>
<p>"Collision!" said Roger. "Some of these space-happy
cadets might get excited, and I for one don't want to
wind up as a flash in Earth's atmosphere!"</p>
<p>"Why, you have radar, to see anything that goes on."</p>
<p>"Oh, sure," said Roger, "I can keep this wagon outa
their way, but will they stay outa mine? Why my
father told me once—" Roger choked on his food and
turned away to the radar screen.</p>
<p>"Well," said Tom after a moment, "what <i>did</i> your
father tell you?"</p>
<p>"Ah—nothing—not important. But I've got to get a
cross-fix on Regulus before we start our little games."</p>
<p>Tom looked puzzled. Here was another of Roger's
quick changes of attitude. What was it all about? But
there was work to do, so Tom shrugged his shoulders
and returned to the control deck. He couldn't forget
what Roger had said about a collision, though.</p>
<p>"Excuse me, Captain," said Tom, "but have there
been any serious collisions in space between ships?"</p>
<p>"Sure have, Tom," replied Strong. "About twenty
years ago, maybe less, there was a whole wave of them.
That was before we developed superrebound pulse
radar. The ships were faster than the radar at close
range."</p>
<p>Strong paused. "Why do you ask?"</p>
<p>Before Tom could answer, there was a sharp warning
from the captain.</p>
<p>"Eight o'clock, Corbett!"</p>
<p>Tom ripped open the envelope containing the sealed
orders. "Congratulations," he read. "You are in command
<span class="pagenum"><SPAN name="Page_124" id="Page_124"></SPAN></span>of the defenders. You have under your command,
Squadrons A—B—C—D—E—F. Squadrons G and H are
your enemies, and at this moment are on their way to
attack Luna City. It is your job to protect it and destroy
the enemy fleet. Spaceman's luck! Walters, Commander
Space Academy, Senior Officer Solar Guard."</p>
<p>"Roger," yelled Tom, "we've been selected as flagship
for the defenders! Get me a course to Luna City!"</p>
<p>"Good for us, spaceboy. I'll give you that course in a
jiffy!"</p>
<p>" ... <i>Capella</i> to <i>Polaris</i>—am standing by for your
orders...." Tony Richards' voice crackled over the
teleceiver. One by one the twenty-three ships that
made up the defender's fleet checked in for orders.</p>
<p>"Astro," shouted Tom, "stand by for maneuver—and
be prepared to give me every ounce of thrust you can
get!"</p>
<p>"Ready, willing and able, Tom," replied Astro. "Just
be sure those other space jockeys can keep up with me,
that's all!"</p>
<p>Tom turned to Captain Strong.</p>
<p>"What do you think of approaching—"</p>
<p>Strong cut him off. "Corbett, you are in complete
command. Take over—you're losing time talking
to me!"</p>
<p>"Yes, sir!" said Tom. He turned back to the control
board, his face flushed with excitement. Twenty-four
ships to maneuver and the responsibility all his own.
Via a chart projected on a screen, he studied various
approaches to the Moon and Luna City. What would
he do if he were in command of the invading fleet? He
noticed the Moon was nearing a point where it would
be in eclipse on Luna City itself. He studied the chart
further, made several notations and turned to the teleceiver.</p>
<p>"Attention—attention—flagship <i>Polaris</i> to Squadrons
<span class="pagenum"><SPAN name="Page_125" id="Page_125"></SPAN></span>
B and C—proceed to chart seven—sectors eight and
nine. You will patrol those sectors. Attention Squadrons
D and F—proceed to Luna City at emergency space
speed, hover at one hundred thousand feet above Luna
City spaceport and wait for further orders. Attention,
ships three and four of Squadron F—you will proceed
to chart six—sectors sixty-eight through seventy-five.</p>
<div class="figcenter"> <ANTIMG src="images/im133.png" width-obs="395" height-obs="480" alt=""Attention Squadrons D and F—proceed to Luna City"" title="" /> <span class="caption">"Attention Squadrons D and F—proceed to Luna City"</span></div>
<p><span class="pagenum"><SPAN name="Page_126" id="Page_126"></SPAN></span></p>
<p>Cut all rockets and remain there until further orders.
The remainder of Squadron F—ships one and two—will
join Squadron A. Squadron A will stand by for
further orders." Tom glanced at the clock and punched
the intercom button.</p>
<p>"Have you got that course, Roger?"</p>
<p>"Three degrees on the starboard rockets, seventy-eight
degrees on the up-plane of the ecliptic will put
you at the corner of Luna Drive and Moonset Land in
the heart of Luna City, spaceboy!" answered Roger.</p>
<p>"Get that, Astro?" asked Tom on the intercom.</p>
<p>"All set," replied Astro.</p>
<p>"Attention all ships in Squadron A—this is flagship—code
name Starlight—am changing course. Stand by
to form up on me!"</p>
<p>Tom turned back to the intercom.</p>
<p>"Power deck, execute!"</p>
<p>At more than five thousand miles an hour, the <i>Polaris</i>
hurtled toward its destination. One by one the remaining
ships moved alongside until all six had their needlelike
noses pointed toward the pale satellite of the
Moon.</p>
<p>"I'd like to know what your plans are, Tom," said
Strong, when the long haul toward the Moon had settled
down to a routine. "Just idle curiosity, nothing
more. You don't have to tell me if you don't want to."</p>
<p>"Golly, yes," said Tom, "I'd be very grateful for your
opinion."</p>
<p>"Well, let's have it," said the captain. "But as for my
opinion—I'll listen, but I won't say anything."</p>
<p>Tom grinned sheepishly.</p>
<p>"Well," he began, "if I were in command of the invading
fleet, I would strike in force—I'd have to, to do
damage with only eight ships. There are three possible
approaches to Luna City. One is from the Earth side,
using the eclipse corridor of darkness as protection. To
<span class="pagenum"><SPAN name="Page_127" id="Page_127"></SPAN></span>meet that, I've stationed two ships at different levels
and distances in that corridor so that it would be impossible
for an invasion to pass unnoticed."</p>
<p>"You mean, you'd be willing to give up two ships to
the invader to have him betray his position. Is that
right?"</p>
<p>"Yes, sir. But I've also sent Squadrons B and C to
sectors eight and nine on chart seven. So I have a roving
squadron to go to their aid, should the invader
strike there. And on the other hand, should he manage
to get through my outer defense, I have Squadrons D
and E over Luna City itself as an inner defense. As for
Squadron A, we'll try to engage the enemy first and
maybe weaken him; at least reduce the full force of his
attack. And then have Squadrons B, C, D and E finish
him off, by attack from three different points."</p>
<p>Strong nodded silently. The young cadet was shaping
up a defensive strategy with great skill. If he could
only follow through on his plans, the invaders of Luna
City wouldn't have much chance of success—even if
willing to take heavy losses.</p>
<p>Roger's voice came on. "Got a report for you, Tom.
From command ship, Squadron B. They've sighted the
invaders and are advancing to meet them."</p>
<p>Tom checked his charts and turned to the intercom.</p>
<p>"Send them this message, Roger," he said. "From
Starlight, to command ship, Squadrons B and C—approach
enemy ships from position of chart nineteen,
sections one through ten."</p>
<p>"Right!" said Roger.</p>
<p>Strong smiled. Tom was driving his heaviest force
between the invading fleet and its objective—forcing
the aggressors into a trap.</p>
<p>Tom gave more crisp orders to his squadrons. He
asked Roger for an estimated range, and then, rechecking
his position, turned again to the intercom.
<span class="pagenum"><SPAN name="Page_128" id="Page_128"></SPAN></span></p>
<p>"Astro, how much could you get out of this baby by
opening the by-pass between the cooling pumps and
the reactant chamber? That'd mean feeding the stuff
into the motors only half cooled."</p>
<p>Strong turned, started to speak, then clamped his
lips together.</p>
<p>"Another quarter space speed, roughly," replied
Astro, "about fifteen hundred miles more an hour. Do
you want me to do that?"</p>
<p>"No, not now," replied Tom. "Just wanted to know
what I could depend on, if I get stuck."</p>
<p>"O.K.," said Astro. "Let me know!"</p>
<p>"Why use emergency speed, Corbett?" asked Strong.
"You seem to have your enemy right where you want
him now."</p>
<p>"Yes, sir," replied Tom. "And the enemy knows I
have him. He can't possibly attack Luna City now. But
he can still run away. He can make his escape by this
one route."</p>
<p>Tom walked to the chart and ran his finger on a line
away from the invader's position into the asteroid belt.</p>
<p>"I don't want him to get away," Tom explained.
"And with the extra speed, we can cut him off, force
him to turn into a position where the remainder of my
fleet would finish him off."</p>
<p>"You'll do this with just the <i>Polaris</i>?"</p>
<p>"Oh, no, sir," said Tom. "I'd use the <i>Arcturus</i>, <i>Capella</i>
and the <i>Centauri</i>, as well."</p>
<p>"Are you sure those other ships can equal your
speed?"</p>
<p>"They've got exactly the same type engines as we
have here on the <i>Polaris</i>, sir. I'm sure they could—and
with perfect safety."</p>
<p>Strong hesitated a moment, started to ask a question,
then stopped and walked to the chart screen. He
checked the figures. He checked them four times, then
<span class="pagenum"><SPAN name="Page_129" id="Page_129"></SPAN></span>
turned to Tom with a grin and an outstretched hand.</p>
<p>"I've got to offer my congratulations, Tom. This
maneuver would wipe them out. And I've got a notion
that you'd come off without the loss of a single ship,
plus, and it is a big plus, keeping the invaders more
than fifty thousand miles away from their objective!"</p>
<p>The captain turned to the teleceiver. "Rocket cruiser
<i>Polaris</i> to control tower at Space Academy—"</p>
<p>There was a crackle of static and then the deep voice
of Commander Walters boomed from the speaker.</p>
<p>"Spaceport control to <i>Polaris</i>. Come in, Steve."</p>
<p>In a few brief sentences, Strong outlined Tom's plan
of action to the Academy commander. The commander's
face on the teleceiver widened into a grin,
then broke out in a hearty laugh.</p>
<p>"What's that, sir?" asked Captain Strong.</p>
<p>"Very simple, Steve. All of us—all the Academy top
brass—develop a foolproof test for cadet maneuvers.
And then your young Corbett makes us look like amateurs."</p>
<p>"But didn't you expect one side or the other to win?"
asked Strong.</p>
<p>"Of course, but not like this. We've been expecting
a couple of days of maneuver, with both sides making
plenty of mistakes that we could call them on. But here
Corbett wraps the whole thing up before we can get
our pencils sharpened."</p>
<p>"Better stuff cotton in Corbett's ears before he hears
all this," rasped Roger Manning over the intercom. "Or
his head'll be too big to go through the hatch."</p>
<p>"Quiet, Manning," came Astro's voice from the
power deck. "Your mouth alone is bigger than Tom's
head'll ever be."</p>
<p>"Look, you Venusian ape—" began Roger, but Commander
Walters' voice boomed out again. His face on
the teleceiver screen was serious now.
<span class="pagenum"><SPAN name="Page_130" id="Page_130"></SPAN></span></p>
<p>"Attention! Attention all units! The battle has been
fought and won on the chart screen of the rocket
cruiser <i>Polaris</i>. The Luna City attack has been repelled
and the invading fleet wiped out. All units and ships
will return to Space Academy at once. Congratulations
to all and end transmission."</p>
<p>The commander's face faded from the screen. Captain
Strong turned to Tom. "Good work," he said.</p>
<p>He was interrupted by a crackle of static from the
teleceiver. A face suddenly appeared on the screen—a
man's face, frightened and tense.</p>
<p>"S O S." The voice rang out through the control deck.</p>
<p>"This is an S O S. Space passenger ship <i>Lady Venus</i> requests
assistance immediately. Position is sector two,
chart one hundred three. Emergency. We must
have—"</p>
<p>The screen went blank, the voice stopped as though
cut off by a knife. Strong frantically worked the teleceiver
dials to re-establish contact.</p>
<p>"<i>Polaris</i> to <i>Lady Venus</i>," he called. "Come in <i>Lady
Venus</i>. Rocket cruiser <i>Polaris</i> calling <i>Lady Venus</i>.
Come in! Come in!"</p>
<p>There was no answer. The passenger ship's instruments
had gone dead.
