VII TO MAKE A SPACEMAN

THE SEHGEANT CROUCHED in the air, his feet drawn up. "At the count of one," he was saying, "take the ready position, with your feet about six inches from the steel. At the count of two, place your feet firmly against the steel and push off." He shoved against the steel wall and shot into the air, still talking, "Hold the count of four, turn on the count of five-" His body drew up into a ball and turned over a half turn, "-check your rotation-" His body extended again, "-and make contact on the count of seven-" His toes touched

the far wall, "-letting your legs collapse softly so that your momentum will be soaked up without rebound." He collapsed loosely, like an empty sack, and remained floating near the spot where he had landed.

The room was a cylinder fifty feet in diameter in the center of the ship. The entire room was mounted in rollers and was turned steadily in the direction opposite to the spin of the ship and with the same angular speed: thus it had no net spin. It could be entered only from the end, at the center of rotation.

It was a little island of "free fall"-the free-fall gymnasium. A dozen youngster cadets clung to a grab line running fore-and-aft along the wall of the gym and watched the sergeant. Matt was one of the group.

"And now, gentlemen, let's try it again. By the numbers-One! Two! Three!" by the count of five, at which time they all should have turned in the air, neatly and together, all semblance of order was gone. There were collisions, one cadet had even failed to get away from the grab line, and two cadets, refugees from a midair skirmish, were floating aimlessly toward the far end of the room. Their faces had the bewildered look of a dog trying to get traction on smooth ice as they threshed their arms and legs in an effort to stay their progress.

"No! No! No!" said the sergeant and covered his face with his hands. "I can't bear to look. Gentlemen-please! A little coordination. Don't throw yourself at the far wall like an Airedale heading into a fight. A steady, firm shove- like this."

He took off sideways, using the traction given him by his space boots, and intercepted the two deserters, gathering one in each arm and letting his momentum carry the three bodies slowly toward the far end of the grab line, "Grab on," he told them, "and back to your places. Now, gentlemen-once more. Places! By the numbers-normal push off, with arrested contact-one!"

A few moments later he was assuring them that he would much rather teach a cat to swim.

Matt did not mind. He had managed to reach the far wall and stay there. Without grace, proper timing, nor at the spot he had aimed for, but he had managed it, after a dozen failures. For die moment he classed himself as a spaceman.

When the class was dismissed he hurried to his room and into his own cubicle, selected a spool on Martian history, inserted it in his projector, and began to study. He had been tempted to remain in the free-fall gymnasium to practice; he wanted very badly to pass the "space legs" test-free-fall acrobatics-as those who had passed it and qualified in the use of basic space suits as well were allowed one liberty a month at Terra Station.

But he had had an extra interview with Lieutenant Wong a few days before. It had been brief, biting, and had been concerned with the efficient use of his time.

Matt did not want another such-nor the five demerits that went with it. He settled his head in the neck rest of his study chair and concentrated on the recorded words of the lecturer while scenes in color-stereo passed in front of him, portraying in chill beauty the rich past of the ancient planet.

The projector was much like the study box he had used at home, except that it was more gadgeted,1 could project in three dimensions, and was hooked in with the voice writer. Matt found this a great time-saver. He could stop the lecture, dictate a summary, then cause the projector to throw his printed notes on the screen.

Stereo-projection was a time-saver for manual subjects as well. "You are now entering the control room of a type A-6 utility rocket," the unseen lecturer would say, "and will practice an airless landing on Luna"-while the camera moved through the door of the rocket's pilot room and panned down to a position corresponding to the pilot's head. From there on a pictured flight could be made very realistic.

Or it might be a spool on space suits. "This is a four-hour suit," the voice would say, "type M, and may be worn anywhere outside the orbit of Venus. It has a low-capacity rocket unit capable of producing a total change of speed in a 300-lb. mass of fifty foot-seconds. The built-in radio has a suit-to-suit range of fifty miles. Internal heating and cooling is-" By the time Matt's turn came for space-suit drill he knew as much about it as could be learned without practice.

His turn came when he passed the basic free-fall test. He was not finished with free-fall drill-there remained group

precision drill, hand-to-hand combat, use of personal weapons, and other refinements-but he was judged able to handle himself well enough. He was free, too, to go out for free-fall sports, wrestling, bank tennis, jaijilai, and several others -up to now he had been eligible only for the chess club. He picked space polo, a game combining water polo and assault with intent to maim, and joined the local league, in the lowest or "bloody nose" group.

He missed his first chance at space-suit drill because a battered nose had turned him into a mouth breather-the respirator for a type-M suit calls for inhaling through the nose and exhaling through the mouth. But he was ready and anxious the following week. The instructor ordered his group to "Suit up!" without preliminary, as it was assumed that they had studied the instruction spool.

The last of the ship's spin had been removed some days before. Matt curled himself into a ball, floating free, and spread open the front of his suit. It was an unhandy process; he found shortly that he was trying to get both legs down one leg of the suit. He backed out and tried again. This time the big fishbowl flopped forward into the opening.

Most of the section were already in their suits. The instructor swam over to Matt and looked at him sharply. "You've passed your free-fall basic?"

"Yes," Matt answered miserably.

"It's hard to believe. You handle yourself like a turtle on its back. Here." The instructor helped Matt to tuck in, much as if he were dressing a baby in a snow suit. Matt blushed.

The instructor ran through the check-off list-tank pressure, suit pressure, rocket fuel charge, suit oxygen, blood oxygen (measured by a photoelectric gadget clipped to the earlobe) and finally each suit's walky-talky unit. Then he herded them into the airlock.

Matt felt his suit swell up as the pressure died away in the lock. It was becoming slightly harder to move his arms and legs. "Hook up your static lines," called out the instructor. Matt uncoiled his from his belt and waited. Reports came in: "Number one hooked." "Number two hooked."

"Number three hooked," Matt sang out into the mike in

his helmet as he snapped his line to the belt of cadet number four. When they were all linked like mountain climbers the instructor hooked himself to the chain and opened the outer door of the lock. They looked out into the star-flecked void.

"Click on," directed the instructor, and placed his boots gently against the side of the lock. Matt did likewise and felt the magnetic soles of his boots click against the steel. "Follow me and stay closed up." Their teacher walked along the wall to the open door and performed an awkward little squatting spread-eagle step. One boot was still inside the door, flat to the wall, with the toe pointing inboard; with the other he reached around the corner, bent his knees, and felt for the outer surface of the ship. He withdrew the foot still in the lock and straightened his body-with which he almost disappeared, for he now stuck straight out from the ship, his feet flat to her side.

Following in order, Matt went out through the door. The ninety degree turn to get outside the lock and "standing" on the outer skin of the ship he found to be tricky; he was forced to use his hands to steady himself on the door frame. But he got outside and "standing up." There was no true up-and-down; they were still weightless, but the steel side was a floor "under" them; they stuck to it as a fly sticks to a ceiling.

Matt took a couple of trial steps. It was like walking in mud; his feet would cling stickily to the ship, then pull away suddenly. It took getting used to.

They had gone out on the dark side of the ship. Sun, Moon and Earth lay behind its bulk, underfoot. Not even Terra Station could be seen.

"We'll take a walk," announced the instructor, his voice hollow in their helmets. "Stick together." He started around the curving side of the ship. A cadet near the end of the chain tried to break both magnetized boots free from the ship at the same time. He accomplished it, by jumping-and then had no way' to get back. He moved out until his static line tugged at the two boys on each side of him.

One of them, caught with one foot free of the ship in walking, was broken loose also, though he reached wildly for the steel and missed. The cadet next to him, last in line, came loose in turn.

No more separated, as the successive tugs on the line had used .up the energy of the first cadet's not-so-violent jump. But three cadets now dangled on the line, floating and twisting grotesquely.

The instructor caught the movement out of the corner of his eye, and squatted down. He found what he sought, a steel ring recessed in the ship's side, and snapped his static line to it. When he was certain that the entire party was not going to be dragged loose, he ordered, "Number nine-haul them in, gently-very gently. Don't pull yourself loose doing it."

A few moments later the vagrants were back and sticking to the ship. "Now," said the instructor, "who was responsible for that piece of groundhog stupidity?"

No one answered. "Speak up," he said sharply. "It wasn't an accident; it's impossible to get both feet off unless you hop. Speak up, confound it, or I'll haul every last one of you up in front of the Commandant."

At the mention of that awful word a small, meek voice answered, "I did it, sergeant."

"Hold out your hand, so I'll know who's talking. I'm not a mind reader."

"Vargas-number ten." The cadet held out his arm.

"Okay. Back to the airlock, everybody. Stick together." When they were there, the instructor said, "Inside, Mr. Vargas. Unhook your line, snap to the lock and wait for us. You'll take this drill over-about a month from now."

"But sergeant-"

"Don't give me any lip, or so help me, I'll report you" for AWOL-jumping ship."

Silently the cadet did as ordered. The instructor leaned inside to see that Vargas actually anchored himself, then straightened out. "Come, gentlemen- we'll start again-and no monkey-shines. This is a drill, not a tea party."

Presently Matt said, "Sergeant Hanako-"

"Yes? Who is it?"

"Dodson. Number three. Suppose we had all pulled loose?"

"We'd 'ave had to work our way back on our rocket units."

Matt thought about it. "Suppose we didn't have reaction, units?"

"Nothing much-under these circumstances. The officer of the watch knows we're outside; the radio watch is guarding our frequency. They would just have tracked us by radar until they could man a scooter and come get us. Just the same-listen, all of "you-just because they've got you wrapped in cotton batting is no reason to behave like a bunch of school girls. I don't know of any nastier, or lonelier, way to die than all by yourself in a space suit, with your oxygen running out." He paused. "I saw one once, after they found him and fetched him back."

They were rounding the side of the ship, and the bulging sphere of the Earth had been rising over their metal horizon.

Suddenly the Sun burst into view.

"Mind the glare!" Sergeant Hanako called out. Hastily Matt set his visor for maximum interference and adjusted it to shade his face and eyes. He did not attempt to look at the Sun; he had dazzled his eyes often enough from the viewports of the ship's recreation rooms, trying to blank out the disc of the Sun exactly, with a coin, so that he might see the prominences and the ghostly aurora. It was an unsatisfactory business; the usual result was a headache and spots before his eyes.

But he never grew tired of looking at Earth. *

She hung before him, great and fat and beautiful, and seeming more real than when seen through a port. She swelled across Aquarius, so huge that had she been in Orion she would have concealed the giant hunter from Betelgeuse to Rigel.

Facing them was the Gulf of Mexico. Above it sprawled North America wearing the polar cap like a chef's hat. The pole was still bright under the failing light of late northern summer. The sunrise line had cleared North America except for the tip of Alaska; only the central Pacific was dark.

Someone said, "What's that bright dot in the Pacific, over near the edge? Honolulu?"

Honolulu did not interest Matt; he searched, as usual, for Des Moines-but the Mississippi Valley was cloudy; he could not 'find it. Sometimes he could pick it out with his naked eyes, when the day was clear in Iowa. When it was night in North America he could always tell which jewel of light was home-or thought he could.

They were facing Earth so that the North Pole seemed "up" to them. Far off to the right, almost a ship's width from the Earth, nearly occulting Regulus in Leo, was the Sun, and about half way between the Sun and Earth, in Virgo, was a crescent Moon. Like the Sun, the Moon appeared no larger than she did from Earth surface. The gleaming metal sides of Terra Station, in the sky between Sun and Moon and ninety degrees from Earth, outshone the Moon. The Station, a mere ten miles away, appeared half a dozen times as wide as the Moon.

That's enough rubbernecking," announced Hanako. "Let's .move around." They walked forward, looking the ship over and getting the feel of her size, until the sergeant stopped them. "Any further and we'd be slapping our feet over the Commandant's head. He might be asleep." They sauntered aft and Hanako let them work around the edge of the stern until they looked across the openings of her mighty tubes. He called them back promptly. "Even though she ain't blasted in years, this area is a little bit hot-and you're not shielded from the pile abaft frame ninety-three anyhow. Forward, now!"

By hot he did not mean warm to the touch, but radioactive.

He led them amidships, unhooked himself from the cadet next to him and hooked the lad's line to the ship. "Number twelve-hook to steel," he added.

"The trick to jetting yourself in space,"-he went on, 'lies in balancing your body on the jet-the thrust has to pass through your center of gravity. If you miss and don't correct it quickly, you start to spin, waste your fuel, and have the devil's own time stopping your spin.

"It's no harder than balancing a walking stick on your finger-but the first time you try it, it seems hard.

"Rig out your sight." He touched a stud at his belt; a light metal gadget snapped up in front of his helmet so that a small metal ring was about a yard in front of his face. "Pick out a bright star, or a target of any sort, lined up in the direction you want to go. Then take the ready position- no, no! Not yet-I'll take it."

He squatted down, lifted himself on his hands, and very cautiously broke his boots loose from the side, then steadied himself on a cadet within reach. He turned and stretched out, so that he floated with his back to the ship, arms and legs extended. His rocket jet stuck straight back at the ship from the small of his back; his sight stuck out from his helmet in the opposite direction.

He went on, "Have the firing switch ready in your right hand. Now, have you fellows ever seen a pair of adagio dancers? You know what I mean-a man wears a piece of leopard skin and a girl wearing less than that and they go leaping around the stage, with him catching her?"

Several voices answered yes. Hanako continued, "Then you know what I'm talking about. There's one stunt they always do-the girl jumps and the man pushes her up and balances her overhead on one hand. He has his hand at the small of her back and she lays there, artistic-like.

"That's exactly the way you got to ride a jet. The push comes at the small of your back and you balance on it. Only you have to do the balancing-if the push doesn't pass exactly through your center of gravity, you'll start to turn. You can see yourself starting to turn by watching through your sight.

"You have to correct it before it gets away from you. You do this by shifting your center of gravity. Drag in the arm or leg on the side toward which you've started to turn. The trick is-"

"Just a second, Sarge," someone cut in, "you said that just backwards. You mean; haul in the arm or leg on the other side, don't you?"

"Who's talking?"

"Lathrop, number six. Sorry."

"I meant what I said, Mr. Lathrop."

"But-"

"Go ahead, do it your way. The rest of the class will do it my way. Let's not waste time. Any questions? Okay, stand clear of my jet."

The half circle backed away until stopped by the anchored static lines. A bright orange flame burst from the sergeant's back and he moved straight out or "up," slowly at first, then with increasing speed. His microphone was open; Matt could hear, by radio only, the muted rush of his jet-and could hear the sergeant counting seconds: "And . . . one! . . . and . . . two! . . . and . . . three!" With the count of ten, the jet and the counting stopped.

Their instructor was fifty feet "above" them and moving away, back toward them. He continued to lecture. "No matter how perfectly you've balanced you'll end up with a small amount of spin. When you want to change direction, double up in a ball-" He did so. "-to spin faster-and snap out of it when you've turned as far as you want." He suddenly flattened out and was facing them. "Cut in your jet and balance on it to straighten out on your new course-before you drift past the direction you want."

He did not cut in his jet, but continued to talk, while moving away from them and slowly turning. "There is always some way to squirm around on your axis of rotation so that you can face the way you need to face for a split second at least. For example, if I wanted to head toward the Station-" Terra Station was almost a right angle away from his course; he went through contortions appropriate to a monkey dying in convulsions and again snapped out in starfish spread, facing the Station-but turning slow cartwheels now, his axis of rotation unchanged.

"But I don't want to go to the Station; I want to come back to the ship." The monkey died again; when the convulsions ceased, the sergeant was facing them. He cut in his jet and again counted ten seconds. He hung in space, motionless with respect to the ship and his class and about a quarter mile away. "I'm coming in on a jet landing, to save time." The jet blasted for twenty seconds and died; he moved toward them rapidly.

When he was still a couple of hundred feet away, he flipped over and blasted away from the ship for ten seconds. The sum of his maneuvers was to leave him fifty feet away and approaching at ten feet per second. He curled up in a ball again and came out of it feet toward the ship.

Five seconds later his boots clicked to steel and he let himself collapse without rebound. "But that is not the way you'll do it," he went on. "My tanks hold more juice than yours do-you've got fifty seconds of power, with each second good for a change of speed on one foot-second-that's for three hundred pounds of mass; some of you skinny guys will go a little faster.

"Here's your flight plan: ten seconds out, counted. Turn as quick as you can and blast fifteen seconds back. That means you'll click on with five foot- seconds. Even your crippled grandmother ought to be able to do that without bouncing off. Lathrop! Unhook-you're first."

As the cadet came up, Hanako anchored himself to the ship with two short lines and took from his belt a very long line. He snapped one end to a hook in the front of the cadet's belt and the other to his own suit. The student looked at it with distaste. "Is the sky hook necessary?"

Sergeant Hanako stared at him. "Sorry, Commodore-regulations. And shut up. Take the ready position."

Silently the cadet crouched, then he was moving away, a fiery brush growing out of his back. He moved fairly straight at first, then started to turn.

He pulled in a leg-and turned completely over.

"Lathrop-cut off your jet!" snapped Hanako. The flame died out, but the figure in the suit continued to turn and to recede. Hanako paid out his safety line. "Got a big fish here, boys," he said cheerfully. "What do you think he'll weigh?" He tugged on the line, which caused Lathrop to spin the other way, as the line had wound itself around him. When the line was free he hauled the cadet in.

Lathrop clicked on. "You were right, sergeant. I want to try it again-your way."

"Sorry. The book says a hundred per cent reserve fuel for this drill; you'd have to recharge." Hanako hesitated. "Sign up for tomorrow morning-I'll take you as an extra."

"Oh-thanks, Sarge!"

"Don't mention it. Number one!"

The next cadet moved out smoothly, but returned on an angle and had to be snubbed with the safety line before he could click on. The next cadet had trouble orienting himself at all. He receded, his back to the -ship, and seemed to be about to continue in the direction of Draco till the end of time. Hanako tugged gently on the safety line while letting it run through his gloves and turned him around toward the ship. "Ten seconds on the jet, while I keep a strain on the line," he ordered. The safety line kept the cadet straightened out until he got back. "Number three!" called out Hanako.

Matt stepped forward with a feeling of tight excitement. The instructor hooked the safety line and said, "Any questions? Go ahead when ready."

"Okay." Matt crouched, broke his boots free, and stretched out. He steadied himself against the sergeant's knee. In front of him lay the northern constellations. He picked out the Pole Star as a target, then loosened the safety catch of the firing switch in his glove.

"And . . . one!" He felt a soft, steady pressure across his saddle, a shove of not quite ten pounds. Polaris seemed to vibrate to the blasting of the tiny jet. Then the star swung to the left, beyond the ring of the sight.

He pulled in his right arm and right leg. The star swung faster, checked and started back. Cautiously he extended his right-side limbs again-and almost forgot to cut the jet on the count of ten.

He could not see the ship. Earth swam in the velvety darkness off to the right. The silence and aloneness were more intense, more complete, than he had ever experienced.

"Time to turn," said Hanako in his ear.

"Oh-" said Matt, and grabbed his knees.

The heavens wheeled around him. He saw the ship swinging into sight, too late. He checked by starfishing, but it had moved on past. "Take it easy," advised the sergeant. "Don't curl up quite so tight, and catch it on the next time around. There's no hurry."

He drew himself in again, but not so much. The ship came around again, though twice as far away as it had been before. This time he checked before it swung past. The figures crawling on her side were about three hundred feet away and still backing away from him. He got someone's helmet centered in his sight, pressed the switch and began to count.

For a few worried seconds he thought that something had gone wrong. The figures on the ship did not seem- to be getting nearer and now they were swinging slowly past him. He was tempted to blast again-but Hanako's orders had been specific; he decided not to.

The ship swung out of sight; he doubled up in a ball to bring it around more quickly. When it showed up it was distinctly nearer and he felt relieved. Actually the two bodies, ship and man, had been closing at five feet per second-but five feet per second is a slow walk.

A little more than a minute after cutting his jet, he jack-knifed to bring his boots in front of him and clicked on, about ten feet from the instructor.

Hanako came over and placed his helmet against Mart's so he could speak to him privately, with the radio shut off. "A good job, kid, the way you kept your nerve when you swung past. Okay-I'll post you for advanced training."

Matt remembered to cut out his walky-talky. "Gee, thanks!"

"You did it, not me." Hanako cut back in the voice circuit. "Okay, there- number four."

Matt wanted to chase back to his room, find Tex, and do some boasting. But there were seven more to go. Some did well, some had to be fished out of difficulty.

The last man outdid himself. He failed to cut off his power in spite of Hanako's shouts for him to do so. He moved away from the ship in a wide curve and commenced to spin, while the sergeant whipped at the safety line to try to stop the spin and head him back. At the end of a long fifty seconds his power gave out; he was nearly a thousand feet away and still receding rapidly.

The sergeant played him like a fisherman fighting a barracuda, then brought him in very, very slowly, for there was no way to check whatever speed the tension on the line placed on him.

When at last he was in, clicked down, and anchored by static line, Hanako sighed. "Whew!" he said. "I thought I was going to have to go get him." He went to the cadet and touched helmets, radio off.

The cadet did not shut off his instrument. "I don't know," they heard him reply. "The switch didn't go bad-I just couldn't seem to move a muscle. I could hear you shouting but I couldn't move."

Matt went back to the airlock with the group, feeling considerably sobered. He suspected that there would be a vacant place at supper. It was the Commandant's policy to get a cadet who was to be dropped away from the ship without delay. Matt did not question the practice, but it jarred him when he saw it happening-it brought the cold breath of disaster en his own neck.

But he cheered up as soon as he was dismissed. Once he was out of his suit and had inspected it and stowed it as the rules required, he zipped to his room, bouncing his turns in a fashion not approved for in-ship progress.

He banged on the door of Tex's cubicle. "Hey, Tex! Wake up! I've got news for you."

No answer-he opened the door, but Tex was not there. Nor, as it happened, were Pete or Oscar. Disconsolately he went into his own sanctum and picked out a study spool.

Nearly two hours later Tex came bouncing in as Matt was getting ready for lunch and shouted, "Hey! Matt! Mitt me, big boy-shake hands with a spaceman!"

"Huh?"

"I just passed "basic space suit'-sergeant said it was the best first test he had ever seen."

"He did? Oh-"

"He sure did. Oh boy-Terra Station, here I come!"
