The Best of Planet Stories, No. 1

  Ah, yes, the compartment. That was where Mitkey came in, although even the Professor didn't know it yet. In fact the Professor didn't even know that Mitkey existed.

  "Und now," he was saying to his favorite listener, "idt is budt a madter of combining der fuel tubes so they work in obbosite bairs. Und then-"

  That was the moment when the Herr Professor's eyes first fell on Mitkey. Rather, they fell upon a pair of gray whiskers and a black, shiny little nose protruding from a hole in the baseboards.

  "Veil!" he said, "vot haff ve here! Mitkey Mouse himself! Mitkey, how would you like to go for a ride, negst veek? Ve shall see."

  That is how it came about that the next time the Professor sent into town for supplies, his order included a mousetrap-not one of the vicious kind that kills, but one of the wire-cage kind. And it had not been set, with cheese, for more than ten minutes before Mitkey's sharp little nose had smelled out that cheese and he had followed his nose into captivity.

  Not, however, an unpleasant captivity. Mitkey was an honored guest. The cage reposed now on the table at which the Professor did most of his work, and cheese in indigestion-giving abundance was pushed through the bars, and the Professor didn't talk to himself any more.

  "You see, Mitkey, I vas going to sendt to der laboratory in Hardtfordt for a vhite mouse, budt vhy should I, mit you here? I am sure you are more soundt and healthy and able to vithstand a long chourney than those laboratory mices. No? Ah, you viggle your viskers and that means yes, no? Und being used to living in dargk holes, you should suffer less than they from glaustrophobia, no?"

  And Mitkey grew fat and happy and forgot all about trying to get out of the cage. I fear that he even forgot about the family he had abandoned, but he knew, if he knew anything, that he need not worry about them in the slightest. At least not until and unless the Professor discovered and repaired the hole in the refrigerator. And the Professor's mind was most emphatically not on refrigeration.

  "Und so, Mitkey, ve shall place this vane so-it iss only of assistance in der landing, in an atmosphere. It and these vill bring you down safely and slowly enough that der shock-absorbers in der movable combartment vill keep you from bumping your head too hard, I think." Of course, Mitkey missed the ominous note to that "I think" qualification because he missed all the rest of it. He did not, as has been explained, speak English. Not then.

  But Herr Oberburger talked to him just the same. He showed him pictures. "Did you effer see der Mouse you vas named after, Mitkey? Vhat? No? Loogk, this is der original Mitkey Mouse, by Valt Dissney. Budt I think you are cuter, Mitkey."

  Probably the Professor was a bit crazy to talk that way to a little gray mouse. In fact, he must have been crazy to make a rocket that worked. For the odd thing was that the Herr Professor was not really an inventor. There was, as he carefully explained to Mitkey, not one single thing about that rocket that was new. The Herr Professor was a technician; he could take other people's ideas and make them work. His only real invention-the rocket fuel that wasn't one-had been turned over to the United States Government and had proved to be something already known and discarded because it was too expensive for practical use.

  As he explained very carefully to Mitkey, "It iss burely a matter of absolute accuracy and mathematical correctness, Mitkey. Idt iss all here-ve merely combine-und ve achieff vhat, Mitkey?

  "Eggscape velocity, Mitkey! Chust barely, it adds up to eggscape velocity. Maybe. There are yet unknown facgtors, Mitkey, in der ubper atmosphere, der troposphere, der stratosphere. Ve think ve know eggsactly how mudch air there iss to calculate resistance against, but are ve absolutely sure? No, Mitkey, ve are not. Ve haff not been there. Und der marchin iss so narrow that so mudch as an air current might affect idt."

  But Mitkey cared not a whit. In the shadow of the tapering aluminum-alloy cylinder he waxed fat and happy.

  "Der tag, Mitkey, der tag! Und I shall not lie to you, Mitkey. I shall not giff you valse assurances. You go on a dancherous chourney, mein little friendt.

  "A vifty-vifty chance ve giff you, Mitkey. Not der moon or bust, but der moon und bust, or else maybe safely back to earth. You see, my boor little Mitkey, der moon iss not made of green cheese und if it were, you vould not live to eat it because there iss not enough atmosphere to bring you down safely und vith your viskers still on.

  "Und vhy then, you may veil ask, do I send you? Because der rocket may not attain eggscape velocity. Und in that case, it iss still an eggsperiment, budt a different vun. Der rocket, if it goes not to der moon, falls back on der earth, no? Und in that case certain instruments shall giff us further information than ve haff yet about things up there in space. Und you shall giff us information, by vether or not you are yet alife, vether der shock absorbers und vanes are sufficient in an earth-equivalent atmosphere. You see?

  "Then ladter, vhen ve send rockets to Venus maybe vhere an atmosphere eggsists, ve shall haff data to calculate the needed size of vanes und shock-absorbers, no? Und in either case, und vether or not you return, Mitkey, you shall be vamous! You shall be der virst liffing greature to go oudt beyond der stratosphere of der earth, out into space.

  "Mitkey, you shall be der Star-Mouse! I enfy you, Mitkey, und I only vish I vere your size, so I could go, too."

  Der tag, and the door to the compartment. "Gootbye, little Mitkey Mouse." Darkness. Silence. Noise!

  "Der rocket-if it goes not to der moon-falls back on der earth, no?" That was what the Herr Professor thought. But the best-laid plans of mice and men gang aft agley. Even star-mice.

  All because of Prxl.

  The Herr Professor found himself very lonely. After having had Mitkey to talk to, soliloquies were somehow empty and inadequate.

  There may be some who say that the company of a small gray mouse is a poor substitute for a wife; but others may disagree. And, anyway, the Professor had never had a wife, and he had a mouse to talk to, so he missed one and, if he missed the other, he didn't know it.

  During the long night after the launching of the rocket, he had been very busy with his telescope, a sweet little eight-inch reflector, checking its course as it gathered momentum. The exhaust explosions made a tiny fluctuating point of light that was possible to follow, if one knew where to look.

  But the following day there seemed to be nothing to do, and he was too excited to sleep, although he tried. So he compromised by doing a spot of housekeeping, cleaning the pots and pans. It was while he was so engaged that he heard a series of frantic little squeaks and discovered that another small gray mouse, with shorter whiskers and a shorter tail than Mitkey, had walked into the wire-cage mousetrap.

  "Veil, yell," said the Professor, "vot haff ve here? Minnie? Iss it Minnie come to look for her Mitkey?"

  The Professor was not a biologist, but he happened to be right. It was Minnie. Rather, it was Mitkey's mate, so the name was appropriate. What strange vagary of mind had induced her to walk into an unbaited trap, the Professor neither knew nor cared, but he was delighted. He promptly remedied the lack of bait by pushing a sizable piece of cheese through the bars.

  Thus it was that Minnie came to fill the place of her far-traveling spouse as repository for the Professor's confidences. Whether she worried about her family or not there is no way of knowing, but she need not have done so. They were now large enough to fend for themselves, particularly in a house that offered abundant cover and easy access to the refrigerator.

  "Ah, and now it iss dargk enough, Minnie, that ve can loogk for that husband of yours. His viery trail across the sky. True, Minnie, it iss a very small viery trail and der astronomers vill not notice it, because they do not know vhere to loogk. But ve do.

  "He iss going to be a very vamous mouse, Minnie, this Mitkey of ours, vhen ve tell der vorld about him and about mein rocket. You see, Minnie ve haff not told them yet. Ve shall vait and giff der gomplete story all at vunce. By dawn of tomorrow yell, "Ah, there he iss, Minnie! Vaint, but there. I'd hold you up to der scope and let you loogk, but it vould
not be vocused right for your eyes, and I do not know how to fix it.

  "Almost vun hundred thousand miles, Minnie, and still agcelerating, but not for much longer. Our Mitkey iss on schedule; in fagt he iss going vaster than ve had vigured, no? It iss sure now that he vill eggscape the gravitation of der earth, and fall upon der moon!"

  Of course, it was purely coincidental that Minnie squeaked.

  "Ah, yess, Minnie, little Minnie. I know, I know. Ve shall neffer see our Mitkey again, and I almost vish our eggsperiment hadt vailed. Budt there are gompensations, Minnie. He shall be der most vamous of all mites. Der Star-Mouse! Virst lifting greature effer to go beyond der gravitational bull of earth!"

  The night was long. Occasionally high clouds obscured vision.

  "Minnie, I shall make you more gomfortable than in that so-small vire cage. You vould like to seem to be vree, vould you not, vithout bars, like der animals at modern zoos, vith moats insteadt?"

  And so, to fill in an hour when a cloud obscured the sky, the Herr Professor made Minnie her new home. It was the end of a wooden crate, about half an inch thick and a foot square, laid flat on the table, and with no visible barrier around it.

  But he covered the top with metal foil at the edges, and he placed the board on another larger board which also had a strip of metal foil surrounding the island of Minnie's home. And wires from the two areas of metal foil to opposite terminals of a small transformer which he placed near by.

  "Und now, Minnie, I shall blace you on your island, vhich shall be liberally supplied mitt cheese and vater, and you shall vind it iss an eggcelent blace to liff. But you vill get a mild shock 'or two vhen you try to step off der edge of der island. It vill not hurt much, but you vill not like it, and after a few tries you vill learn not to try again, no? Und-"

  And night again.

  Minnie happy on her island, her lesson well learned. She would no longer so much as step on the inner strip of metal foil. It was a mouse-paradise of an island, though. There was a cliff of cheese bigger than Minnie herself. It kept her busy. Mouse and cheese; soon one would be a transmutation of the other.

  But Professor Oberburger wasn't thinking about that. The Professor was worried. When he had calculated and recalculated and aimed his eight-inch reflector through the hole in the roof and turned out the lights, something was wrong.

  Yes, there are advantages to being a bachelor after all. If one wants a hole in the roof, one simply knocks a hole in the roof and there is nobody to tell one that one is crazy. If winter comes, or if it rains, one can always call a carpenter or use a tarpaulin.

  But the faint trail of light wasn't there. The Professor frowned and re-calculated and re-re-calculated and shifted his telescope three-tenths of a minute and still the rocket wasn't there.

  "Minnie, something "iss wrong. Either der tubes haff stopped viring, or . . ."

  Or the rocket was no longer traversing a straight line relative to its point of departure. By straight, of course, is meant parabolically curved relative to everything other than velocity.

  So the Herr Professor did the only thing remaining for him to do, and began to search, with the telescope, in widening circles. It was two hours before he found it, five degrees off course already and veering more and more into a- Well, there was only one thing you could call it. A tailspin.

  The darned thing was going in circles, circles which appeared to constitute an orbit about something that couldn't possibly be there. Then narrowing into a concentric spiral.

  Then-out. Gone. Darkness. No rocket flares.

  The Professor's face was pale as he turned to Minnie.

  "It iss imbossible, Minnie. Mein own eyes, but it could not be. Even if vun side stopped viring, it could not haff gone into such sudden circles." His pencil verified a suspicion. "Und, Minnie, it decelerated vaster than bossible. Even mitt no tubes viring, its momentum vould haff been more-"

  The rest of the night-telescope and calculus-yielded no clue. That is, no believable clue. Some force not inherent in the rocket itself, and not accountable by gravitation-even of a hypothetical body-had acted.

  "Mein poor Mitkey."

  The gray, inscrutable dawn. "Mein Minnie, it vill haff to be a secret. Ve dare not publish vhat ve saw, for it vould not be believed. I am not sure I believe it myself, Minnie. Berhaps because I vas offertired vrom not sleeping, I chust imachined that I saw —"

  Later. "But, Minnie, ve shall hope. Vun hundred vifty thousand miles out, it vas. It vill fall back upon der earth. But I gannot tell vhere! I thought that if it did, I vould be able to galculate its course, und . . . But after those goncentric circles — Minnie, not even Einstein could galculate vhere it vill land. Not effen me. All ve can do iss hope that ve shall hear of vhere it falls."

  Cloudy day. Black night jealous of its mysteries.

  "Minnie, our poor Mitkey. There is nothing could have gauzed . . ." But something had.

  Prxl.

  Prxl is an asteroid. It isn't called that by earthly astronomers, because-for excellent reasons-they have not discovered it. So we will call it by the nearest possible transliteration of the name its inhabitants use. Yes, it's inhabited.

  Come to think of it, Professor Oberburger's attempt to send a rocket to the moon had some strange results. Or rather, Prxl did.

  You wouldn't think that an asteroid could reform a drunk, would you? But one Charles Winslow, a besotted citizen of Bridgeport, Connecticut, never took a drink when-right on Grove Street-a mouse asked him the road to Hartford. The mouse was wearing bright red pants and vivid yellow gloves.

  But that was fifteen months after the Professor lost his rocket. We'd better start over again.

  Prxl is an asteroid. One of those despised celestial bodies which terrestrial astronomers call vermin of the sky, because the darned things leave trails across the plates that clutter up the more important observations of novae and nebulae. Fifty thousand fleas on the dark dog of night.

  Tiny things, most of them. Astronomers have been discovering recently that some of them come close to Earth. Amazingly close. There was excitement in 1932 when Amor came within ten million miles; astronomically, a mere mashie shot. Then Apollo cut that almost in half, and in 1936 Adonis came within less than one and a half million miles.

  In 1937, Hermes, less than half a million but the astronomers got really excited when they calculated its orbit and found that the little mile-long asteroid can come within a mere 220,000 miles, closer than Earth's own moon.

  Some day they may be still more excited, if and when they spot the 3/8-mile asteroid Prxl, that obstacle of space, making a transit across the moon and discover that it frequently comes within a mere hundred thousand miles of our rapidly whirling world.

  Only in event of a transit will they ever discover it, though, for Prxl does not reflect light. It hasn't, anyway, for several million years since its inhabitants coated it with a black, light-absorbing pigment derived from its interior. Monumental task, painting a world, for creatures half an inch tall. But worth it, at the time. When they'd shifted its orbit, they were safe from their enemies. There were giants in those days-eight-inch tall marauding pirates from Diemos. Got to Earth a couple of times too, before they faded out of the picture, Pleasant little giants who killed because they enjoyed it. Records in now-buried cities on Diemos might explain what happened to the dinosaurs. And why the promising Cro-Magnons disappeared at the height of their promise only a cosmic few minutes after the dinosaurs went west.

  But Prxl survived. Tiny world no longer reflecting the sun's rays, lost to the cosmic killers when its orbit was shifted.

  Prxl. Still civilized, with a civilization millions of years old. Its coat of blackness preserved and renewed regularly, more through tradition than fear of enemies in these later degenerate days. Mighty but stagnant civilization, standing still on a world that whizzes like a bullet.

  And Mitkey Mouse.

  Klarloth, head scientist of a race of scientists, tapped his assistant Bemj on what would have
been Bemj’s shoulder if he had had one. "Look," he said, "what approaches Prxl. Obviously artificial propulsion."

  Bemj looked into the wall-plate and then directed a thought-wave at the mechanism that jumped the magnification of a thousand-fold through an alteration of the electronic field.

  The image leaped, blurred, then steadied. "Fabricated," said Bemj. "Extremely crude, I must say. Primitive explosive-powered rocket. Wait, I'll check where it came from."

  He took the readings from the dials about the viewplate, and hurled them as thoughts against the psychocoil of the computer, then waited while that most complicated of machines digested all the factors and prepared the answer. Then, eagerly, he slid his mind into rapport with its projector. Klarloth likewise listened in to the silent broadcast.

  Exact point on Earth and exact time of departure. Untranslatable expression of curve of trajectory, and point on that curve where deflected by gravitational pull of Prxl. The destination-or rather the original intended destination--of the rocket was obvious, Earth's moon. Time and place of arrival on Prxl if present course of rocket was unchanged.

  "Earth," said Klarloth meditatively. "They were a long way from rocket travel the last time we checked them. Some sort of a crusade, or battle of beliefs, going on, wasn't there?"

  Bemj nodded. "Catapults. Bows and arrows. They've taken a long stride since, even if this is only an early experimental thing of a rocket. Shall we destroy it before it gets here?"

  Klarloth shook his head thoughtfully. "Let's look it over. May save us a trip to Earth; we can judge their present state of development pretty well from the rocket itself."

  "But then we'll have to . . ."

  "Of course. Call the Station. Tell them to train their attractorepulsors on it and to swing it into a temporary orbit until they prepare a landing-cradle. And not forget to damp out the explosive before they bring it down."

  "Temporary force-field around point of landing-in case?"

  "Naturally."

  So despite the almost complete absence of atmosphere in which the vanes could have functioned, the rocket came down safely and so softly that Mitkey, in the dark compartment, knew only that the awful noise had stopped.
