THE SPACE BEYOND -- John W. Campbell, Jr.
Edited by Roger Elwood
Introduction by Isaac Asimov
Afterword by George Zebrowski
BIG, BIG, BIG
by Isaac Asimov
The thing about John Campbell is that he liked things big. He liked big men
with big ideas working out big applications of their big theories. And he
liked it fast. His big men built big weapons within days; weapons that were,
moreover, without se"ous shortcomings, or at least, with no shortcomings that
could not be corrected as follows: "Hmm, something's wrong-oh, I see-of
course." Then, in two hours, something would be jerry-built to fix the jerry-
built device.
- The big applications were, usually, in the form of big weapons to fight big
wars on tremendous scales. Part of it was, of course, Campbell's conscious
attempt to imitate and surpass Edward E. ("Doc") Smith. The world-shaking,
escalating conflicts in Campbell's stories, as in The Space Beyond in this
collection, is a reflection of the escalating conflict on the printed page
between John and Doc.
A great deal of Campbell's science is sheer gobble-dygook that you must not
take seriously. You have to read it as a foreign language that the characters
understand and for which the action and the astronomical background serve as a
translation.
In some places, Campbell is deliberately and bullheaded-ly wrong and one can
never be sure whether he actually believes the nonsense, or whether he is
doing it just to irritate and provoke his readers into thinking hard.
In the December 1934 Astounding Stories, John Campbell, writing under the
pseudonym, Karl van Campen, published "The Irrelevant," hi which the heroes
were rescued from a deadly interplanetary dilemma by working
out a method for creating energy out of nothing. In this way, they defied the
law of conservation of energy which, it can be argued, is the most fundamental
law of the universe.
Campbell did this by arguing that the quantity of energy produced by a change
in velocity was different according to the frame of reference you chose for
it, and that by switching from one frame to another you could create more
energy than you consumed.
This is dead wrong. I won't argue the reasons here because I don't want to
start a controversy. The argument that began with "The Irrelevant" continued
in the letter columns of Astounding for an incredible length of time, with
Campbell (always writing letters under the name of Karl van Campen)
maintaining his views against all attacks-as in later years, he would
maintain, with equal unswerving vigor, all attacks against his equally
indefensible views in favor of dianoetics the Hieronymus machine, the Dean
drive, and so on. He might stop arguing points and allow them to drop into
oblivion, but he would never openly admit he was wrong.
"The Irrelevant" was the only story that John ever published under the van
Campen pseudonym, but Marooned was a sort of never-published (till now) sequel
under the same pseudonym, and it made use, in the end, of the same fallacy of
a broken law of conservation of energy. I don't even feel guilty about giving
away the climax in that story because I don't want anyone to be fooled by it.
It doesn't work. You have been warnedl
Yet, on the other hand, John's incredibly vivid imagination would sometimes
strike gold and would inspire other writers into striking gold also. The great
writers of the Golden Age in Astounding were more Campbell than themselves. I
admit, freely and frequently, that this was so in my case. Other writers are
perhaps more reluctant to do so.
Campbell's hand is, I believe, quite obvious in the early work of the greatest
of all writers of the Golden Age, Robert A. Heinlein. All, included hi this
volume, became "Sixth Column" by Heinlein, published under the pseudonym of
Anson MacDonald, hi the January, February, and March 1941 issues of
Astounding.
The example of Campbell's golden prescience that struck me most forcibly in
the stories of this collection occurs in The Space Beyond. There, Campbell
mentions that lithium bombarded with protons gives off alpha particles and
that beryllium bombarded with alpha particles gives off protons and that the
two mixed together can keep each other going in a "self-maintaining atomic
explosion."
Actually, this is not so. It takes a high-energy proton to initiate the
lithium reaction and beryllium releases low-energy protons; at any rate,
protons with too low an energy to break down the lithium. And the same is true
in reverse for the alpha particles.
Nevertheless, the suggestion is remarkable. It was made in the mid-thirties
and surely not many people were then thinking of the possibility of a nuclear
chain reaction, which is what Campbell was suggesting. Eventually, not many
years after The Space Beyond was written, a practical nuclear chain reaction
was discovered, that of uranium fission. It was practical precisely because it
worked under the impetus of tow-energy neutrons.
Campbell's brightness in seeing the importance of the nuclear chain reaction
may well explain the most remarkable of his predictive visions. During World
War II, he kept insisting that nuclear power would be developed before the
war's end. Once he heard of the discovery of uranium fission, his
understanding of nuclear chain reactions made the atomic bomb seem to him a
natural consequence. This was also true for the physicist, Leo Szilard, but
for practically no one else.
Campbell went on to inspire a series of stories by other authors on the
subject of power through uranium fission, the most notable being "Blowups
Happen" by Robert A. Heinlein, "Nerves" by Lester del Rey, and "Deadline" by
Cleve Cartmill. (These all appeared in Astounding, in the September 1940,
September 1942, and March 1944 issues respectively.)
Campbell was eventually investigated by a suspicious American government for
knowing too much, but it was easy for him to demonstrate that he didn't know
too much -it was the world that knew too little.
With characteristic cosmic-optimism, Campbell carried nuclear power forward to
its extremes without ever considering its danger. To control nuclear power
meant, to
Mm in All, the ability to cure disease miraculously; although, alas, the
reality has shown us that radiation is the most deadly potential producer of
disease the world has ever known.
In fact, there is a peculiar blind spot in prediction that affects us all,
even Campbell. One sees the extrapolations of the present in a straight-line
way. One misses the surprises.
In All, Campbell lists the few chemical specifics humanity had developed by
the early 1930s and moves directly forward to nuclear panaceas-without ever
foreseeing the antibiotics. And yet, I distinctly remember sitting with him in
his office once, before antibiotics had been discovered, and listening to him
tell me that since almost all pathogenic bacteria were destroyed in the soil,
there must be substances in soil bacteria that would destroy harmful germs and
cure disease.
In a way, Campbell's vision of nuclear power was self-defeating. Lured by his
success there, he went on to attempt to lead the way into a morass of semi-
mystical pathways, through psi and related subjects, from which he never
entirely emerged.
Campbell's love of bigness showed itself at its most glamorous and remarkable
in his tendency to describe astronomical bodies of the largest variety in
dramatic but utterly realistic prose. It is here, for instance, that he shines
in The Space Beyond and in Marooned.
But there, Campbell was, at times, betrayed. In the forty years since these
stories were written, astronomy has made strides (thanks to radio telescopes
and planetary probes) that not even Campbell could have foreseen, and the
result has been to dwarf even the most liberal imaginations of earlier
generations.
Campbell describes the super-giant stars vividly and beautifully in The Space
Beyond and, indeed, they steal the show in that novelette. Making them
Cepheids adds to the supernal glory (even though Campbell has the notion, it
seems, that the more massive a Cepheid the shorter its period, when it is the
reverse that is true).
However, no such super-star could exist by modern notions-or, indeed, by the
astronomical notions of the time at which the story was written. In the 1920s,
Arthur
S. Eddington advanced the mass-luminosity law which made it quite dear that
stars very much more massive than our Sun could not exist. The radiation
pressure from within would cause them to explode at once. In the case of a
star as large as those Campbell describes, the result would be an immediate
supernova.
Furthermore, even if a star as massive as Campbell's super-giants could be
imagined to hang together, thb rate of consumption of hydrogen fuel that would
be required to keep it glowing at its incredible level would probably drag it
through its entire stay in the main sequence for a hundred thousand years. It
would only be during that stay that planets could form and evolve in a fashion
that would produce life" as we know it and if they had formed when the star
itself had (at the appropriately colossal distance), there would simply have
been no time for the planet to evolve any life at aM, to say nothing of
advanced intelligences.
Imagine what Campbell could have done had he been able to write the story a
generation later. In place of such super-giant stars, even groups of them, he
could have had a quasar-an entire galactic center of millions of stars
interacting in some fashion to form something as far beyond a star as a star
is beyond a planet.
Or he could have imagined his stars collapsing (as they would surely have
done) into black holes. Given an area in space where there were black holes by
the dozens, whatever problems would have arisen, as sure as Campbell was
Campbell, they would have been solved.
Or perhaps, he would have had his environment filled with a white hole-that
area in space where the matter endlessly pushing into a black hole somewhere
else is emerging hi great gouts of radiating energy. Perhaps a quasar is a
white hole and he could have combined concepts and driven through space and
time by using the cosmic ferry of a black hole.
And if, since these stories were written, our knowledge of the Universe has
increased a thousandfold, our knowledge of our own Solar system has been
refined ten-thousandfold. We have mapped, in detail, the hidden side of the
Moon, and men have stood upon our satellite's surface. Unmanned probes have
landed on Mars and Venus,
and the surfaces of Mars and Mercury have been mapped in detail, as well as
those of the tiny Martian satellites, Phobos and Deimos. Jupiter has been seen
at short distances, and a probe is gliding its way to Saturn even as I write.
How does Marooned seem in the light of all this?
We-must begin by forgetting about "synthium" that beautiful example of one
mainstay of early science fiction-the wonder-metal. Element 101 has indeed
been discovered since Campbell wrote Marooned but it is named mendelevium and
it is unstable, as are all elements beyond atomic number 83. Even if it were
stable, we know what its properties would be like, and they would be nothing
like those of synthium. In fact, the properties of no conceivable metal in the
real world would be like those of synthium.
Next, there is another old standby-the difficulty of getting past the asteriod
belt. I used that one myself in my very first published story "Marooned Off
Vesta." The asteroid belt, however, is a paper tiger. The material in it is
strewn so widely over so vast a volume that any spaceship going through it is
not at all likely to see anything of visible size. The Jupiter-probes, Pioneer
10 and Pioneer 11, went through without trouble and detected less dust than
had been expected.
Still a third commonplace of science fiction was its tendency toward water-
oxygen chauvinism. Almost every world encountered in science fiction stories
had its water ocean and its oxygen atmosphere.
Campbell needed an atmosphere for Ganymede, so he gave it one, but I think he
knew better. Any gases in the vicinity of that satellite exist only in traces.
However, Campbell was probably correct in placing quantities of ice on its
surface. The low density of Ganymede and of its sister-world Callisto make the
presence of such materials very likely. Campbell makes the ices those of water
and carbon dioxide. It is likely, however, that frozen •ammonia is there
rather than frozen carbon dioxide.
And what about Jupiter? Campbell suggests that this could only be explored
with something like synthium since without it, ships could not pass the
asteroid belt and could not even penetrate to the depths of Earth's own ocean.
Not so, for within a quarter-century after the
story had been written, not only had the asteroid belt been shorn of its
terrors, but human beings had made it down to the deepest abyss of the ocean
in bathyscaphes-and without synthium.
But Jupiter itself is a harder nut, and Campbell portrays its giant
intractable nature gloriously well. He is wrong in details, inevitably. He
describes its atmosphere as mostly nitrogen and water with helium and "some
hydrogen." Later on, he describes the hydrogen content as "a minute trace" and
places a rather larger quantity of free oxygen there.
Undoubtedly, there is water in the Jovian atmosphere; it has been detected. So
has helium been detected, but not nitrogen, and certainly not oxygen. Ammonia
and methane, which Campfoell doesn't mention, are present, but the major
component is hydrogen. In fact, all of Jupiter is at least 90 percent
hydrogen, mostly in the liquid form.
Campbell correctly assumes there is a greenhouse effect in Jupiter's
atmosphere; that solar radiation is trapped and that the temperature is higher
than it might otherwise be. But he has his heroes in the arctic zone where he
describes it as fiercely cold.
Thanks to Jupiter-probe data, gathered in 1974, however, we believe that the
temperature of Jupiter rises steadily as one penetrates the atmosphere. Six
hundred miles below the cloud layer, the temperature is already 3600 C. It
seems quite likely that by the time the ship had penetrated to a depth at
which the atmosphere had become dense enough to resist further penetration,
the problem would be heat and not cold.
But what's the difference? Whenever a story is placed at the edge of science
as it is known at the time, and whenever the author allows his imagination to
steer him forward as. best it can, making intelligent or dramatic
extrapolations-the advance of real science is bound to outmode him in spots.
This must be accepted, and to be wise after the event, as I have been here, or
to shine in 'hindsight, as I do, is of no significance.
The question is this: Were Campbell's extrapolations, whether right or wrong,
nevertheless intelligent and dramatic? And the answer is: A thousand times,
yes!
Campbell might be outwritten by many others, in and out of science fiction, in
terms of characterization, plot, and dialog, but no one ever outdid him in
visualizing the grandeur of the Universe.
MAROONED
I
In August 2133, Robert Randall discovered synthium. He announced simply that
he had created element 101, which had, according to his modest report,
"unusually interesting properties." Since civilization has been based on
metals for the past seven thousand years, and syn-thium's "unusually
interesting properties" included such things as its unheard of (and, because
they had no machines at the time capable of determining it) undeter-minedly
great tensile strength, and its crystalline, transparent allotropic form with
a strength only slightly less, RandaU was most unnecessarily modest in his
claims.
That was several years after the last expedition to Jupiter had been destroyed
by the customary meteor, and the last of Stephenson's three ships was
tastefully draped over an asteroid. Naturally there were half a dozen
expeditions trying to get the Interplanetary Committee's consent to a new
expedition. Bar Corliss had been trying patiently for four and a half years.
Jinimie Mattorn had been trying to get permission for-four of their "Explorer"
type ships. They'd been turned down regularly and with punctuality by the
Committee, because parium was the latest word in strong materials at the time-
something like two and a quarter million pounds to the square inch. Good, but
not good enough to stop a really determined meteor, of course-and most of
those found out Jupiter's way were very determined.
Then too, parium fuel tanks had a nasty habit of "failing" when one of the
overanxious explorers loaded a twenty-ton tank with thirty^seven tons.
All in all, Jupiter kept pretty much to himself. Only one ship got past the
asteroid belt-they couldn't dodge out of the plane of the ecliptic in those
days, because that meant taking more fuel for the dodging. Erickson did it He
fell back into the Minor Orbits some six years later, and the bodies of the
crew were retrieved by the tow-cruiser "Maximum," which pleased the widows to
some extent.
But Randall's mild "unusual properties" hid a world
of high-explosive punch. Since all of the explorer's gang was looking for the
slightest thing in that line, undoubtedly they all read the line. Somewhere or
other, though, Bar Corliss had met Randall. He read the thing, and he suddenly
got a mental picture of Randall: a little sandy-haired man with pale-blue eyes
and a pale-sandy mustache, rather moth-eaten in appearance, slightly stained
by weather and his favorite pipe, wearing clothes apparently made by the
American Packaging Bag company, fitted by the oldest of tailors, Guess and
Gosh, and dyed by Laboratory Fumes. And he remembered him as the discoverer of
triconite-familiarly known as "tricky-nite" and described by him as a "rather
powerful explosive."
So Corliss wandered down to Pittsburgh and American Metals. Randall had a
piece of the stuff, paper thin and impossibly strong. Corliss looked at it,
and grunted. It was the early product, not the refined stuff they turn out
today, and it looked like a poorly tanned pig's hide with the measles. Randall
went into one of his quiet raptures about it, and tried to demonstrate its
strength. He was rather handicapped, because he'd already broken most of the
testing machines trying it out, and they hadn't built a new one yet. But
Corliss wasn't slow in getting the possibilities. Corliss had more money than
he could spend then anyway, so he found out what American Metal's total
possible production of synthium would be, and ordered it for the next six
months.
Jimmie Mattorn got there two days later, and Nord-deutscher Rakete, two and a
half later-they couldn't get in touch with their American representative. So
Corliss wasn't without competition on the thing. Norddeutscher, finding they
couldn't get more than a scrap of synthium from American Metals, bought German
rights to the stuff, and wanted to start making it, and get a rocket under
way.
Corliss was already moving.
That was probably why the things happened as they did. When Corliss built that
ship, he hadn't the faintest idea of the strength he put in it, because he
didn't have the ghost of an idea of the strength of synthium. Besides, he had
carefully drawn plans for a parium ship-four of them actually-and so he just
made them out of synthium instead. He did make a test tank, and broke down his
pumps trying to break the tank. That was all he cared
about though, so he let it go. He was in too much of a faurry.
He'd probably have forgotten something in the rush if be hadn't planned on his
parium ships for so long. If he'd known how long he'd have for planning
afterwards, he'd probably have spent less before. He certainly wouldn't •have
backed out.
You can weld synthium-they could then. But you can't cut it with any saw, or
tool. So the "Mercury" was slapped together in a remarkable hurry. The
synthium plates had to be cast and heat-treated because Corliss wouldn't wait
while rolls and machines were built of it to bend and work it. So he allowed a
little extra size over his original parium blueprints-he found out two years
later that cast and heat-treated synthium was stronger than rolled-and plowed
ahead.
The Germans were at his heels all the way. But his crew-with plenty of money
and no budget-got four ships together in slightly less time than the German
crew did. They loaded them up so fast that they had to get some of their
supplies at the terrific rates prevailing on old Luna.
But the Committee didn't know that; they saw four new ships, of a very strong
metal, with very strong fuel tanks of unusual capacity, and a remarkably
different course laid out that would take men around the asteroid belt- and
the plans were stamped.
Automatically, they turned down the Norddeutscher people when they applied
"until the success or failure of the present expedition has been determined."
The Norddeutscher people had a long wait. And then, of course, when Corliss'
fate was settled they couldn't get approval of their ships, or, for that
matter, any lupiter-bound ships. Corliss settled that for once and for all
with the result of his expedition. They couldn't have gotten men anyway,
probably, for none had the desire to have their ship christened "Mahomet's
Coffin" for so excellent a reason.
Corliss got off Earth in May 2134. The Corliss Jupiter Expedition was
underway. A fleet of four tiny ships, each of five-thousand-ton mass, each
looking, with their raw, unpainted synthium, like a farmer-boy's unsuccessful
effort toward a home-grown and tanned football, mottled with green and yellow
and pink.
They were remarkable looking things, stubby, thick-bellied, and quite hideous,
with their weirdly-shaped wing-attachments sticking out forlornly at a broken
angle.
But they lifted off at ten A.M., May 17, 2134.
Bar Corliss looked at Brad Warren, second in command, with a sour, exaggerated
grimace. "Great gang of planners we are," he commented.
Brad Warren grinned back at him. "Forget something, Bar?"
"Only a few minor things-like soap, and coffee extract and antiseptics.
Nothing really important of course-" Bar chuckled. "Wouldn't the Norddeutscher
crowd like to know that!"
Brad gestured out the port toward the blinding light and the- sharp shadows of
Luna. Half a mile distant loomed the dome of Lunar Metals and Mines No. 3.
"When do we break loose?"
"Don't say the words," moaned Corliss. "Break loose, I mean. That's what the
clerk in the L.M. and M. keeps saying. And, dear God, has he been breaking me
loose. I've got to have the stuff. It's my own fault we haven't got it-and is
he 'breaking me loose' from plenty of cash. Only 22.50 a pound for coffee
extract. Only a dollar a cake for five-cent laundry soap. And as for the water
we've got to have for fuel-!" Bar shook his head and looked piously upward.
"May God bless him-nobody else ever will."
Brad grinned without sympathy. "You knew it was coming on that score; how else
could you get away from old Earth? Even when the famous 'Irrelevant' disproved
the law of conservation of energy in interplanetary work, she didn't disprove
the fact that you needed a lot of kick to dimb away from Earth. We've still
got to climb out most of the way from Earth, so far as gravity goes."
"Uhmmm-but considering they generate power here directly from sunlight in the
Davison photocells, get their water by cooking out the water of
crystallization of the deeper rocks, and have plenty, you'd think they could
sell it for less than thirty-two cents a gallon.
"What's the latest figures on water at Phobos? Interplanetary Minerals sent
anything yet?"
"Uhm," said Brad. "It's down. It seems they found it
wasn't selling well. Three and a half a gallon on Mars, and seventeen and a
quarter on Phobos."
"That's not so stiff. It'll change, though, by the time we get there. And we
need tens of thousands of gallons of it!"
"Well, you still won't be broke," grinned Brad, "and you know damn well the
kick you get out of this is worth it. Anyway-we lift off here any time you say
now. We're loaded with everything, I guess."
"Make it two hours then. That is-two hours and whatever more is needed for
aligning of orbits and so forth. How long did you say we'd have to wait on
Phobos?"
"RandaU was very timely in his invention. Jupiter and Mars will be right, in
about three months. If we take off as you say, we ought to wait about three
months, three days and four hours."
"It could be worse," sighed Bar.
Two hours, forty-seven minutes and thirty-three seconds later, the "Mercury"
and her escorting squadron of three ships got underway. Pale-blue flames
flared for a few seconds as they trembled, soundless in the vacuum of Moon's
surface; then they rose in slow sweeps, rocketing upward, and away. They were
visible to the men watching in the protecting glass and steel of the L.M. and
M. company. But finally, they were lost in the haze of stars that obscured
almost all the heavens, flaring brightly despite the glaring yellow sun.
The steady drone of the great rocket tubes of infusible tungovan grumbled and
echoed and murmured to itself in the metal shells of the ships. The rockets
were mar-velously well-designed. There was little wasted energy here, and
therefore, little noise. Noise is the audible warning of waste energy. They
could not afford wastage of the precious burden of fuel, so there was almost
no noise, only the smooth, carefully engineered flow of gases rushing through
ground, honed and polished rocket tubes, designed as nearly as possible for
absolute stream flow.
To all new spacers, rocket tubes are flimsy-looking things. The metal is less
than an eighth of an inch thick, flimsy, tinny in appearance. It would seem
that those incredibly powerful and light engines, rocket engines, would
certainly burst anything so slight. That again illustrates the refinements of
rocket engineering. It is a well-known
fact that the greater the velocity of a fluid stream, the less the side-
pressure. Those tubes were designed for the greatest possible velocity,
naturally, and since that meant almost no side-pressure, tons of metal could
be shaved from the rocket tubes. Only the great pressure blocks seemed, and
were, capable of resisting strain bracing the egg-shaped combustion chambers.
Hour after hour the tubes moaned and droned. They were running almost white
hot, but they were polished more carefully than the finest telescope mirrors,
and they were in vacuum jackets equally polished, so that almost no heat
escaped from them-for heat, where it isn't wanted, is not only a nuisance, but
a warning of inefficiency.
Presently, the song of the fuel pumps started. They had been feeding the tubes
on the original pressure hi the tanks at first, but now this was falling. Pure
hydrogen and oxygen were 'being taken from the tanks at seven tons, pressure,
and stepped up to the necessary eight for efficient running in the tubes. It
was a gas-but under that pressure, denser than water.
That might have warned them, had they stopped to think then. But it was a
hastily conceived and carried out thing, throughout. They'd raced against time
all the way. When, after seven days they landed on Mars North City field with
wings spread and the parachute air-brake spread to stop them, the ships needed
repair and final adjustment, so much so that the three-month wait on Mars was
no ordeal of monotony. There were plenty of trained mechanicians at Mars North
City to help them, and still it was more of an ordeal of labor. And still
there wasn't any time for recalculation that might have stopped the expedition
then and there.
They loaded up with water-fuel-that is, hydrogen and oxygen gases, at Mars
North City where the gases were cheap, and pulled out to Phobos running heavy.
They replaced the burned fuel there, and at last the "Mercury" and her
companions pulled out on the real trip.
So far they had gone. This trip out to Mars and her moons was old, charted and
laid out by a pair of generations and more of space travel. Over a hundred and
fifty years of exploration, over seventy years of commercial exploitation of
the Minor Planets, and still no human being had passed beyond the magic ring
of the Planetoids.
You have seen a scale map of our system. You know the dimensions. Forty,
seventy, one hundred and one hundred-forty millions of miles are the orbits of
the Minor Planets. Then-the Great Gulf. It's five hundred million to Jupiter,
nine hundred million to Saturn, a billion and three quarters to Uranus. When
the Lord made this system, he used two scales. Maybe he started out with one,
and didn't like the looks of the dinky little system he got -planets with
diameters measured in thousands of miles, orbits with diameters measured in
millions. Maybe he threw that scale away, and decided to start all over with
something worth while. The dust specks he /had, he just forgot, and worked
with a scale reading hi billions instead of millions for the orbits, and he
used tens of thousands of miles for planet diameters.
At any rate, there are two systems really, the Inner System, and the Outer
System, and they're as different as two entirely strange systems might be.
Four, seven, ten and fourteen tens of millions for the Inner System. Four,
eight, seventeen, twenty-eight hundreds of millions for the Outer System.
The "Mercury" was trying to be the Messenger of the Gods, from the Lesser Gods
to Mighty love. And she was the first ship that really stood a chance of
crossing that gulf.
That's quite a hill, there between the Inner and Outer systems. Nearly four
hundred million miles-and every blasted mile of it uphill-with old Sol
dragging, dragging, dragging on the other end. Four hundred million miles of
uphill climb had stopped exploration for a hundred and fifty years and more.
The "Mercury" lifted off Phobos, with her train of three service ships,
distinctly heavy. She staggered as she pulled loose of Mar's gravity. Then she
shifted into high for the climb. Hour after hour the tubes moaned. Then day
after day they coasted, slowing their pace steadily as Sol pulled with his
infinitely untiring grip to stop them. Then for more hours, the tubes droned
and hummed, and then they began to spit and bark unevenly, and the ships
lurched and staggered like mad motes in a beam of light, skittering and
dancing lest some unheeding, trundling rock, weighing perhaps a thousand
quadrillion tons, brush them along with it.
And all day long and all night long, though the only
night here was the nose of the ugly foot-ball thing they called a ship, there
was a steady rain of terrific, sharp pings as tiny, invisibly small planetoids
crashed against the synthium wall. They were going at almost the same speed-as
space speeds go-so the incredible, never-tested strength of synthium turned
those shocks. They were going at almost the same speed-there wasn't much more
difference in their speed than the speed the mightiest shells of Man's armory
attained, about a mile and a half a second. But they were made of only plain,
high-grade nickel-steel armor-plating, the natural alloy of meteors, and the
ships were made of synthium.
So somehow, after three horrible days in there, the men took off their
space^armor suits again, and gobbled a little food (they couldn't eat with
those suits on, of course) and then flopped down to rest.
And through the ships the steady, peaceful thrum and drone of the smoothly
working tubes made sweet music to them. The soft regular chuck-shug-pssiii of
the air circulators and the fuel pumps sounded steady and sweet.
For the "Mercury" was through the Magic Ring, and cruised at last hi that
terra incognita, the no-man's-land beyond the Inner System.
When sleep had restored them, their watches were sharp, sharper than ever
before. For they began to sense the difference. This space was different-it
was the Great Space, the space where things the size of Mars were satellites,
and gravitative control-fields of planets reached out thirty million miles. It
was the Space of the Giants.
And day by day, the Sun. dwindled, grew tinier. And day by day they saw the
pinpoint of Jupiter sweeping into position. Jupiter was huge-but this was the
Great Space. It was still a pinpoint to their eyes.
They let a bit of hydrogen into the vacuum surrounding the rocket tubes now,
so the shields weren't such good insulators, and they put a special soft black
paint on the outside sheath, so radiation was better, and the ships began to
warm up a bit.
And the sun dwindled four hundreds of millions of miles behind, and Jupiter
became a respectable disc, an unchanging disc.
They shut off their rocket tubes then, because most of the fuel was gone. In
fact, they had enough left to permit a landing on one of Jupiter's little
satellites, and, by put-
ting all the fuel in one ship, the smallest, enough to fall back to Earth
safely. But the ships began to get cold. Out there, a planet like Earth would
have a temperature in the neighborhood of two-hundred and thirty degrees below
zero. Those ships were well insulated-but they had to burn a good bit of fuel
to permit life in them, even so.
Ill
"Yes, I agree that Ganymede has an atmosphere," Bar argued tensely, "and that
it may be thick enough to permit us to halt almost entirely by atmospheric
friction instead of by rocket power-highly important saving of fuel of course.
But-Ganymede's only six hundred and sixty thousand from the surface of the
blasted planet, and with the gravitative field Jup's got, that's no distance.
If we go in so far before we stop, we might not be able to get back at all, if
we can't find water there."
"But, Bar, we can save enough fuel by air-braking to a stop to permit us to
pull out from that close approach with our little ship, if necessary."
"Uhmmmmm-maybe. I suppose we'd better. I know there's no real chance of
collecting water on that chunk of rock called Number Nine, fifteen million
miles out from Jupiter though it is." Then in sudden decisiveness, after a
moment of thought, he said, "Shift'er over."
Brad turned to his calculated data, and presently the rocket tubes on one side
moaned loudly, a driving acceleration came again as the weight-warning bell
echoed dully through the ship. Bar Corliss was calling off figures into the
microphone, sending instructions to the three other ships, now within ten
thousand miles of the "Mercury."
The Mercury turned, and the great disc of Jupiter shifted till it was more
nearly straight ahead once more; almost directly before them, the tiny disc of
Ganymede, three thousand two hundred miles in diameter, loomed. It was ringed
with a fat, bright ring, the halo of an atmosphere.
"That atmosphere must be pure hydrogen," said Corliss thoughtfully. "It's cold
as the hinges of hades out there."
"Hydrogen, hell. That planet's too light to hold pure hydrogen with the tug
and cross tug of old Jupiter down there. It's more likely something heavy and
useless like nitrogen."
"We'll know quick enough. We ought to get there in eighteen hours the way
Jup's pulling us now."
The rockets were silent, yet the ships were moving faster
and faster. Mighty Jupiter was dragging at them. Slowly their course bent, and
Ganymede shifted across the windows till it was directly under the nose of the
ship. It was enlarging swiftly now-more and more swiftly. Slowly, slowly
Jupiter's pull dragged the ship over till Ganymede passed the center spot of
the windows, and hung off to the other side. The ship seemed destined to pass
between Ganymede and Jupiter. Then, the throw hesitated, as Ganymede began to
loom; a great round moon, dimly silvered, it hung for a moment as it grew
swiftly, and abruptly the ship was being pulled to the satellite. Ganymede's
gravity was greater than Jupiter's at last!
The thin bright ring of atmosphere expanded, the satellite grew till it seemed
evident the ship would touch the atmospheric rim, and plow on.
"Wings," called Corliss at last. Motors hummed into action, and a slow grating
squeal of gears and racks sounded in the ship. The rocket trembled to the push
of the motors. It was rotating slowly as the powerful collapsible wings thrust
out.
"Put her on high-lift angles, and throw out the airbrakes," suggested Brad. "I
think we're a bit high. We'll need a lot of resistance in the first passage to
cut our speed to an orbital velocity."
For an instant the rockets flared again, pushing the ships back into a path
closer to the satellite. Then, soon, there came a thin high scream, the first
sound to penetrate the walls of the ship from the outside since the asteroids
had been passed, a scream so thin and cold and shrill the sleeping men woke
and joined the active watch. There was a new acceleration now, an acceleration
due not to the rockets, but to the great metal wings, spread and screaming in
the thin air outside, an acceleration actually that thrust them to the side
away from the planet, for the wings, cutting the thin, thin air at more than
three miles a second, were helping to hold the ship down to the planet where
there was air to stop them, while behind, the great air-brake was tugging,
tugging to stop them.
They couldn't hold the planet the first circle, and swung up, away again,
falling out of the atmosphere as their grip on the thinning air weakened,
weakened, and finally broke.
But they'd broken their hyperbolic orbit to an extended ellipse, and turned
the ship so their momentum fought not only Ganymede's strain, but mighty
Jupiter's as well. They were back in Ganymede's atmosphere hi two days,
