Out here, thought Grimes, in a region of space where some sort of interstellar drive must be used, a mine just didn't make sense. On the other hand, it never hurt to be careful. He recalled the words of one of the Instructors at the Academy. "There are old spacemen, and there are bold spacemen, but there aren't any old, bold spacemen."
"A sounding rocket . . ." he said.
"All ready, Captain," replied Beadle.
"Thank you, Number One. After you launch it, maintain full control throughout its flight. Bring it to the buoy or the mine or whatever it is very gently—I don't want you punching holes in it. Circle the target a few times, if you can manage it, and then make careful contact." He paused. "Meanwhile, restart the Mannschenn Drive, but run it in neutral gear. If there is a big bang we might be able to start precessing before the shrapnel hits us." He paused again, then, "Have any of you gentlemen any bright ideas?"
"It might be an idea," contributed Slovotny, "to clear away the laser cannon. Just in case."
"Do so, Sparks. And you, Number One, don't launch your rocket until I give the word."
"Cannon trained on the target," announced Slovotny after only a few seconds.
"Good. All right, Number One. Now you can practice rocketship handling."
"Beadle returned to the viewport, with binoculars strapped to his eyes and a portable control box in his hands. He pressed a button, and almost at once the sounding rocket swam into the field of view, a sleek, fishlike shape with a pale glimmer of fire at its tail, a ring of bright red lights mounted around its midsection to keep it visible at all times to the aimer. Slowly it drew away from the ship, heading towards the enigmatic ball that hung in the blaze of the searchlight. It veered to one side to pass the target at a respectable distance, circled it, went into orbit about it, a miniscule satellite about a tiny primary.
Grimes started to get impatient. He had learned that one of the hardest parts of a captain's job is to refrain from interfering—even so . . . "Number One," he said at last, "don't you think you could edge the rocket in a little closer?"
"I'm trying, sir," replied Beadle. "But the bloody thing won't answer the controls."
"Do you mind if I have a go?" asked Grimes.
"Of course not, Captain." Implied but not spoken was, "And you're bloody welcome!"
Grimes strapped a set of binoculars to his head, then took the control box. First of all he brought the sounding rocket back towards the ship, then put it in a tight turn to get the feel of it. Before long he was satisfied that he had it; it was as though a tiny extension of himself was sitting in a control room in the miniature spaceship. It wasn't so very different from a rocket-handling simulator.
He straightened out the trajectory of the sounding rocket, sent it back towards the mysterious globe and then, as Beadle had done, put it in orbit. So far, so good. He cut the drive and the thing, of course, continued circling the metallic sphere. A brief blast from a braking jet—that should do the trick. With its velocity drastically reduced the missile should fall gently towards its target. But it did not—as von Tannenbaum, manning the radar, reported.
There was something wrong here, thought Grimes. The thing had considerable mass, otherwise it would never have shown so strongly in the screen of the MPI. The greater the mass, the greater the gravitational field. But, he told himself, there are more ways than one of skinning a cat. He actuated the steering jets, tried to nudge the rocket in towards its objective. "How am I doing, Pilot?" he asked.
"What are you trying to do, Captain?" countered von Tannenbaum. "The elements of the orbit are unchanged."
"Mphm." Perhaps more than a gentle nudge was required. Grimes gave more than a gentle nudge—and with no result whatsoever. He did not need to look at Beadle to know that the First Lieutenant was wearing his best I-told-you-so expression.
So . . .
So the situation called for brute strength and ignorance, a combination that usually gets results.
Grimes pulled the rocket away from the sphere, almost back to the ship. He turned it—and then, at full acceleration, sent it driving straight for the target. He hoped that he would be able to apply the braking jets before it came into damaging contact—but the main thing was to make contact, of any kind.
He need not have worried.
With its driving jet flaring ineffectually the rocket was streaking back towards Adder, tail first. The control box-was useless. "Slovotny!" barked Grimes. "Fire!"
There was a blinding flare, and then only a cloud of incandescent but harmless gases, still drifting towards the ship.
"And what do we do now, Captain?" asked Beadle. "Might I suggest that we make a full report to Base and resume our voyage?"
"You might, Number One. There's no law against it. But we continue our investigations."
Grimes was in a stubborn mood. He was glad that Adder was not engaged upon a mission of real urgency. These bags of Fleet Mail were not important. Revised Regulations, Promotion Lists, Appointments . . . If they never reached their destination it would not matter. But a drifting menace to navigation was important. Perhaps, he thought, it would be named after him. Grimes's Folly . . . He grinned at the thought. There were better ways of achieving immortality.
But what to do?
Adder hung there, and the thing hung there, rates and directions of drift nicely synchronized, and in one thousand seven hundred and fifty-three Standard years they would fall into or around Algol, assuming that Grimes was willing to wait that long—which, of course, he was not. He looked at the faces of his officers, who were strapped into their chairs around the wardroom table. They looked back at him. Von Tannenbaum—the Blond Beast—grinned cheerfully. He remarked, "It's a tough nut to crack, Captain—but I'd just hate to shove off without cracking it." Slovotny, darkly serious, said, "I concur. And I'd like to find out how that repulsor field works." Vitelli, not yet quite a member of the family, said nothing. Deane complained, "If the thing had a mind that I could read it'd all be so much easier . . ."
"Perhaps it's allergic to metal . . ." suggested von Tannenbaum. " We could try to bring the ship in towards it, to see what happens . . ."
"Not bloody likely, Pilot," growled Grimes. "Not yet, anyhow. Mphm . . . you might have something. It shouldn't be too hard to cook up, with our resources, a sounding rocket of all-plastic construction . . ."
"There has to be metal in the guidance system . . ." objected Slovotny.
"There won't be any guidance systems, Sparks. It will be a solid fuel affair, and we just aim it and fire it, and see what happens . . ."
"Solid fuel?" demurred Beadle. "Even if we had the formula we'd never be able to cook up a batch of cordite or anything similar . . ."
"There'd be no need to, Number One. We should be able to get enough from the cartridges for our projectile small arms. But I don't intend to do that."
"Then what do you intend, Captain?"
"We have graphite—and that's carbon. We've all sorts of fancy chemicals in our stores, especially those required for the maintenance of our hydroponics system. Charcoal, sulphur, saltpeter . . . Or we could use potassium chlorate instead of that . . ."
"It could work," admitted the First Lieutenant dubiously.
"Of course it will work," Grimes assured him.
It did work—although mixing gunpowder, especially in Free Fall conditions, wasn't as easy as Grimes had assumed that it would be. To begin with, graphite proved to be quite unsuitable, and the first small sample batch of powder burned slowly, with a vile sulphurous stench that lingered in spite of all the efforts of the air conditioner. But there were carbon water filters, and one of these was broken up and then pulverized in the galley food mixer—and when Grimes realized that the bulkheads of this compartment were rapidly acquiring a fine coating of soot he ordered that the inertial drive be restarted. With acceleration playing the part of gravity things were a little better.
Charcoal 13 percent, saltpeter 75 percent, sulphur 12 percent . . . That, thought Grimes,
trying hard to remember the History of Gunnery lectures, was about right. They mixed a small amount dry, stirring it carefully with a wooden ladle. It was better than the first attempt, using graphite, had been—but not much. And it smelled as bad. Grimes concluded that there was insufficient space between the grains to allow the rapid passage of the flame.
"Spooky," he said in desperation. "Can you read my mind?"
"It's against Regulations," the telepath told him primly.
"Damn the Regulations. I sat through all those Gunnery Course lectures, and I'm sure that old Commander Dalquist went into the history of gunnery very thoroughly, but I never thought that the knowledge of how to make black powder would be of any use at all to a modern spaceman. But it's all there in my memory—if I could only drag it out!"
"Relax, Captain." Spooky Deane told him in a soothing voice. "Relax. Let your mind become a blank. You're tired, Captain. You're very tired. Don't fight it. Yes, sit down. Let every muscle go loose . . ."
Grimes lay back in the chair. Yes, he was tired . . . but he did not like the sensation of cold, clammy fingers probing about inside his brain. But he trusted Deane. He told himself very firmly that he trusted Deane . . .
"Let yourself go back in Time, Captain, to when you were a midshipman at the Academy . . . You're sitting there, on a hard bench, with the other midshipmen around you . . . And there, on his platform before the class, is old Commander Dalquist . . . I can see him, with his white hair and his white beard, and his faded blue eyes looking enormous behind the spectacles . . . And I can see all those lovely little models on the table before him . . . The culverin, the falcon, the carronade . . . He is droning on, and you are thinking, How can he make anything so interesting so boring? You are wondering, What's on for dinner tonight? You are hoping that it won't be boiled mutton again . . . Some of the other cadets are laughing. You half heard what the Commander was saying. It was that the early cannoneers, who mixed their own powder, maintained that the only possible fluid was a wine drinker's urine, their employer to supply the wine . . . And if the battle went badly, because of misfires the gunners could always say that it was due to the poor quality of the booze . . . But you are wondering now if you stand any chance with that pretty little Nurse . . . You've heard that she'll play. You don't know what it's like with a woman, but you want to find out . . ."
Grimes felt his prominent ears turning hot and scarlet. He snapped into full wakefulness. He said firmly, "That will do, Spooky. You've jogged my memory sufficiently. And if any of you gentlemen think I'm going to order a free wine issue, you're mistaken. We'll use plain water, just enough to make a sort of mud, thoroughly mixed, and then we'll dry it out. No, we'll not use heat, not inside the ship. Too risky. But the vacuum chamber should do the job quite well . . ."
"And then?" asked Beadle, becoming interested in spite of himself.
"Then we crush it into grains."
"Won't that be risky?"
"Yes. But we'll have a plastic bowl fitted to the food mixer, and the Chief can make some strong, plastic paddles. As long as we avoid the use of metal we should be safe enough."
They made a small batch of powder by the method that Grimes had outlined. Slovotny fitted a remote control switch to the food mixer in the galley, and they all retired from that compartment while the cake was being crushed and stirred. The bowlful of black, granular matter looked harmless enough—but a small portion of it transferred to a saucer—and taken well away from the larger amount remaining in the bowl—burned with a satisfying whoof! when ignited.
"We're in business!" gloated Grimes. "Adder Pyrotechnics, Unlimited!"
They were in business, and while Grimes, Beadle and von Tannenbaum manufactured a large supply of gunpowder Slovotny and Vitelli set about converting a half-dozen large, plastic bottles into rocket casings. They were made of thermoplastic, so it was easy enough to shape them as required, with throat and nozzle. To ensure that they would retain the shape after firing they were bound about with heavy insulating tape. After this was finished, there was a rocket launcher to make—a tube of the correct diameter, with a blast shield and with the essential parts of a projectile pistol as the firing mechanism.
Then all hands joined forces in filling the rockets. Tubes of stiff paper, soaked in a saturated solution of saltpeter and allowed to dry, were inserted into the casing and centered as accurately as possible. The powder was poured around them, and well tamped home.
While this was being done Spooky Deane—who, until now, had played no part in the proceedings—made a suggestion. "Forgive me for butting in, Captain, but I remember—with your memory—the models and pictures that the Instructor showed the class. Those old chemical rockets had sticks or vanes to make them fly straight . . ."
For a moment this had Grimes worried. Then he laughed. "Those rockets, Spooky, were used in the atmosphere. Sticks or vanes would be utterly useless in a vacuum." But he couldn't help wondering if vanes set actually in the exhaust would help to keep the missiles on a straight trajectory. But unless he used metal there was no suitable material aboard the ship—and metal was out.
Grimes went outside, with von Tannenbaum, to do the actual firing. They stood there on the curved shell plating, held in place by the magnetic soles of their boots. Each of them, too, was secured by lifelines. Neither needed to be told that to every action there is an equal and opposite reaction. The backblast of the home-made rockets would be liable to sweep them from their footing.
Grimes held the clumsy bazooka while the Navigator loaded it, then he raised it slowly. A cartwheel sight had been etched into the transparent shield. Even though the weapon had no weight in Free Fall it still had inertia, and it was clumsy. By the time that he had the target, gleaming brightly in the beam of Adder's searchlight, in the center of the cartwheel he was sweating copiously. He said into his helmet microphone, "Captain to Adder. I am about to open fire."
"Adder to Captain. Acknowledged," came Beadle's voice in reply.
Grimes's right thumb found the firing stud of the pistol. He recoiled involuntarily from the wash of the orange flame that swept over the blast shield—and then he was torn from his hold on the hull plating, slammed back to the full extent of the lifeline. He lost his grip on the rocket launcher, but it was secured to his body by stout, fireproof cords. Somehow he managed to keep his attention on the fiery flight of the rocket. It missed the target, but by a very little. To judge by the straight wake of it, it had not been deflected by any sort of repulsor field.
"It throws high . . ." commented Grimes.
He pulled himself back along the line to exactly where he had been standing before. Von Tannenbaum inserted another missile into the tube. This time, when he aimed, Grimes intended to bring the target to just above the center of the cartwheel. But there was more delay; the blast shield was befogged by smoke. Luckily this eventuality had been foreseen, and von Tannenbaum cleaned it off with a soft rag.
Grimes aimed, and fired.
Again the blast caught him—but this time he hung in an untidy tangle facing the wrong way, looking at nothingness. He heard somebody inside the ship say, "It's blown up!"
What had blown up?
Hastily Grimes got himself turned around. The mysterious globe was still there, but between it and Adder was an expanding cloud of smoke, a scatter of fragments, luminous in the searchlight's glare. So perhaps the nonmetallic missiles weren't going to work after all—or perhaps this missile would have blown up by itself, anyhow.
The third rocket was loaded into the bazooka. For the third time Grimes fired—and actually managed to stay on his feet. Straight and true streaked the missile. It hit, and exploded in an orange flare, a cloud of white smoke which slowly dissipated.
"Is there any damage?" asked Grimes at last. He could see none with his unaided vision, but those on the control room had powerful binoculars at hand.
"No," replied Beadle at last. "It doesn't seem to be scratched."
"Then stand by to let the Pilot an
d myself back into the ship. We have to decide what we do next."
What they did next was a matter of tailoring rather than engineering. Adder carried a couple of what were called "skin-divers' suits." These were, essentially, elasticized leotards, skin-tight but porous, maintaining the necessary pressure on the body without the need for cumbersome armor. They were ideal for working in or outside the ship, allowing absolute freedom of movement—but very few spacemen liked them. A man feels that he should be armored, well armored, against an absolutely hostile environment. Too, the conventional spacesuit has built-in facilities for the excretion of body wastes, has its little tank of water and its drinking tube, has its container of food and stimulant pellets. (Grimes, of course, always maintained that the ideal suit should make provision for the pipe smoker . . .) A conventional spacesuit is, in fact, a spaceship in miniature.
