Major Operation

VERTIGO

It was perhaps inevitable that when the long-awaited indication of intelligent life at last appeared the majority of the ship’s observers were looking somewhere else, that it did not appear in the batteries of telescopes that were being trained on the surface or on the still and cine films being taken by Descartes’ planetary probes, but on the vessel’s close approach radar screens.

In Descartes’ control room the Captain jabbed a button on his console and said sharply, “Communications …

“We have it, sir,” came the reply. “A telescope locked onto the radar bearing-the image is on your repeater screen Five. It is a two- or three stage chemically fueled vehicle with the second stage still firing. This means we will be able to reconstruct its flight path and pinpoint the launch area with fair accuracy. It is emitting complex patterns of radio frequency radiation indicative of high-speed telemetry channels. The second stage has just cut out and is falling away. The third stage, if it is a third stage, has not ignited … It’s in trouble!”

The alien spacecraft, a slim, shining cylinder pointed at one end and thickened and blunt at the other, had begun to tumble. Slowly at first but with steadily increasing speed it swung and whirled end over end.

“Ordnance?” asked the Captain.

“Apart from the tumbling action,” said a slower, more precise voice, “the vessel seems to have been inserted into a very neat circular orbit. It is most unlikely that this orbit was taken up by accident. The lack of sophistication-relative, that is-in the vehicle’s design and the fact that its nearest approach to us will be a little under two hundred miles all point to the conclusion that it is either an artificial satellite or a manned orbiting vehicle rather than a missile directed at this ship.

“If it is manned,” the voice added with more feeling, “the crew must be in serious trouble …

“Yes,” said the Captain, who treated words like nuggets of some rare and precious metal. He went on, “Astrogation, prepare intersecting and matching orbits, please. Power Room, stand by.”

As the tremendous bulk of Descartes closed with the tiny alien craft it became apparent that, as well as tumbling dizzily end over end, the other vessel was leaking. The rapid spin made it impossible to say with certainty whether it was a fuel leak from the unfired third stage or air escaping from the command module if it was, in fact, a manned vehicle.

The obvious procedure was to check the spin with tractor beams as gently as possible so as to avoid straining the hull structure, then defuel the unfired third stage to remove the fire hazard before bringing the craft alongside. If the vessel was manned and the leak was of air rather than fuel, it could then be taken into Descartes’ cargo hold where rescue and first contact proceedings would be possible-at leisure since Meatball’s air was suited to human beings and the reverse, presumably, also held true.

It was expected to be a fairly simple rescue operation, at first …

“Tractor stations Six and Seven, sir. The alien spacecraft won’t stay put. We’ve slowed it to a stop three times and each time it applies steering thrust and recommences spinning. For some reason it is deliberately fighting our efforts to bring it to rest. The speed and quality of the reaction suggests direction by an on-the-spot intelligence. We can apply more force, but only at the risk of damaging the vessel’s hull-it is incredibly fragile by present-day standards, sir.”

“I suggest using all necessary force to immediately check the spin, opening its tanks and jettisoning all fuel into space then whisking it into the cargo hold. With normal air pressure around it again there will be no danger to the crew and we will have time to …”

“Astrogation, here. Negative to that, I’m afraid, sir. Our computation shows that the vessel took off from the sea-more accurately, from beneath the sea, because there is no visible evidence of floating gantries or other launch facilities in the area. We can reproduce Meatball air because it is virtually the same as our own, but not that animal and vegetable soup they use for water, and all the indications point toward the crew being water breathers.”

For a few seconds the Captain did not reply. He was thinking about the alien crew member or members and their reasons for behaving as they were doing. Whether the reason was technical, physiological, psychological or simply alien was, however, of secondary importance. The main thing was to render assistance as quickly as possible.

If his own ship could not aid the other vessel directly it could, in a matter of days, take it to a place which possessed all the necessary facilities for doing so. Transportation itself posed only a minor problem — the spinning vehicle could be towed without checking its spin by attaching a magnetic grapple to its center of rotation, and with the shipside attachment point also rotating so that the line would not twist-shorten and bring the alien craft crashing into Descartes’ side. During the trip the larger ship’s hyper-drive field could be expanded to enclose both vessels.

His chief concern was over the leak and his complete ignorance of how long a period the alien spacecraft had intended to stay in orbit. He had also, if he wanted to establish friendly relations with the people on Meatball, to make the correct decision quickly.

He knew that in the early days of human space flight leakage was a quite normal occurrence, for there had been many occasions when it had been preferable to carry extra air supplies rather than pay the severe weight penalty of making the craft completely airtight. On the other hand the leak and spinning were more likely to be emergency conditions with the time available for their correction strictly limited. Since the alien astronaut or astronauts would not, for some odd reason, let him immobilize their ship to make a more thorough investigation of its condition and because he could not reproduce their environment anyway, his duty was plain. Probably his hesitancy was due to misplaced professional pride because he was passing responsibility for a particularly sticky one to others.

Quickly and with his usual economy of words the Captain issued the necessary orders and, less than half an hour after it had first been sighted, the alien spacecraft was on its way to Sector General.

With quiet insistence the PA was repeating, “Will Senior Physician Conway please contact Major O’Mara …

Conway quickly sized up the traffic situation in the corridor, jumped across the path of a Tralthan intern who was lumbering down on him on six elephantine feet, rubbed fur briefly with a Kelgian caterpillar who was moving in the opposite direction and, while squeezing himself against the wall to avoid being run over by something in a highly refrigerated box on wheels, unracked the hand-set of the communicator.

As soon as he had established contact the PA began insisting quietly that somebody else contact somebody else.

“Are you doing anything important at the moment, Doctor?” asked the Chief Psychologist without preamble. “Engaged on vital research, perhaps, or in performing some life-or-death operation?” O’Mara paused, then added dryly, “You realize, of course, that these questions are purely rhetorical …

Conway sighed and said, “I was just going to lunch.”

“Fine,” said O’Mara. “In that case you will be delighted to know that the natives of Meatball have put a spacecraft into orbit-judging by its looks it may well be their first. It got into difficulties-Colonel Skempton can give you the details-and Descartes is bringing it here for us to deal with. It will arrive in just under three hours and I suggest you take an ambulance ship and heavy rescue gear out to it with a view to extricating its crew. I shall also suggest that Doctors Mannon and Prilicla be detached from their normal duties to assist you, since you three are going to be our specialists in Meatball matters.”

“I understand,” said Conway eagerly.

“Right,” said the Major. “And I’m glad, Doctor, that you realize that there are things more important than food. A less enlightened and able psychologist than myself might wonder at this sudden hunger which develops whenever an important assignment is mentioned. I, of course, realize that this is not an outward symptom of a sense of insecurity but sheer, blasted greed!

“You will have arrangements to make, Doctor,” he concluded pleasantly. “Off.”

Skempton’s office was fairly close so that Conway needed just fifteen minutes-which included the time taken to don a protective suit for the two hundred yards of the journey which lay through the levels of the Illensan chlorine breathers-to reach it.

“Good morning,” said Skempton while Conway was still opening his mouth. “Tip the stuff off that chair and sit down. O’Mara has been in touch. I’ve decided to return Descartes to Meatball as soon as it leaves the distressed spacecraft. To native observers it might appear that the vehicle was taken-one might almost say kidnapped-and Descartes should be on hand to note reactions, make contact if possible and give reassurances. I’d be obliged if you would extricate, treat and return this patient to Meatball as quickly as possible-you can imagine the boon this would be to our cultural contact people.

“This is a copy of the report on the incident radioed from Descartes,” the Colonel went on without, apparently, even pausing for breath. “And you will need this analysis of water taken from the sea around the takeoff-the actual samples will be available as soon as Descartes arrives. Should you need further background information on Meatball or on contact procedures call on Lieutenant Harrison, who is due for discharge now and who will be glad to assist. Try not to slam the door, Doctor.”

The Colonel began excavating deeply in the layer of paperwork covering his desk and Conway closed his mouth again and left. In the outer office he asked permission to use the communicator and got to work.

An unoccupied ward in the Chalder section was the obvious place to house the new patient. The giant denizens of Chalderescol II were water breathers, although the tepid, greenish water in which they lived was almost one hundred percent pure compared with the soupy environment of Meatball’s seas. The analysis would allow Dietetics and Environmental Control to synthesize the food content of the water-but not to reproduce the living organisms it contained. That would have to wait until the samples arrived and they had a chance to study and breed these organisms, just as the E.C. people could reproduce the gravity and water pressure, but would have to wait for the arrival of the spacecraft to add the finishing touches to the patient’s quarters.

Next he arranged for an ambulance ship with heavy rescue equipment, crew and medical support to be made available prior to Descartes’ arrival. The tender should be prepared to transfer a patient of unknown physiological classification who was probably injured and decompressed and close to terminal by this time, and he wanted a rescue team experienced in the rapid emergency transfer of shipwreck survivors.

Conway was about to make a final call, to Thornnastor, the Diagnostician-in-Charge of Pathology, when he hesitated.

He was not quite sure whether he wanted to ask a series of specific questions-even a series of hypothetical questions-or to indulge in several minutes worrying out loud. It was vitally important that he treat and cure this patient. Quite apart from it being his and the hospital’s job to do so, successful treatment would be the ideal way of opening communications with the natives of Meatball and ultimately laying hands on more of those wonderful, thought-controlled surgical instruments.

But what were the owners of those fabulous tools really like? Were they small and completely unspecialized with no fixed physical shape like the tools they used or, considering the mental abilities needed to develop the tools in the first place, were they little more than physically helpless brains dependent on their thought-controlled instruments to feed them, protect them and furnish all their physical needs? Conway badly wanted to know what to expect when the ship arrived. But Diagnosticians, as everyone knew, were unpredictable and even more impatient of muddy or confused thinking than was the Chief Psychologist.

He would be better advised, Conway told himself, to let his questions wait until he had actually seen his patient, which would be in just over an hour from now. The intervening period he would spend studying Descartes’ report.

And having lunch.

The Monitor Survey cruiser popped into normal space, the alien spacecraft spinning like an unwieldy propeller astern, then just as quickly reentered hyperspace for the return trip to Meatball. The rescue tender closed in, snagged the towline which had been left by Descartes and fixed the free end to a rotating attachment point of its own.

Space suited Doctors Mannon and Prilicla, Lieutenant Harrison and Conway watched from the tender’s open airlock.

“It’s still leaking,” said Mannon. “That’s a good sign-there is still pressure inside …

“Unless it’s a fuel leak,” Harrison said.

“What do you feel?” asked Conway.

Prilicla’s fragile, eggshell body and six pipe-stem legs were beginning to quiver violently so it was obvious that it was feeling something.

“The vessel contains one living entity,” said Prilicla slowly. “Its emotional radiation is comprised chiefly of fear and feelings of pain and suffocation. I would say that these feelings have been with it for many days-the radiation is subdued and lacking in clarity due to developing unconsciousness. But the quality of that entity’s mentation leaves no doubt that it is intelligent and not simply an experimental animal …

“It’s nice to know,” said Mannon dryly, “that we’re not going to all this trouble for an instrument package or a Meatball space puppy …

“We haven’t much time,” said Conway.

He was thinking that their patient must be pretty far gone by now. It’s fear was understandable, of course, and its pain, suffocation and diminished consciousness were probably due to injury, intense hunger and foul breathing water. He tried to put himself in the Meatball astronaut’s position.

Even though the pilot had been badly confused by the apparently uncontrollable spinning, the being had deliberately sought to maintain the spin when Descartes tried to take it aboard because it must have been smart enough to realize that a tumbling ship could not be drawn into the cruiser’s hold. Possibly it could have checked its own spin with steering power if Descartes had not been so eager to rush to its aid-but that was simply a possibility, of course, and the spacecraft had been leaking badly as well. Now it was still leaking and spinning and, with its occupant barely conscious, Conway thought he could risk frightening it just a little more by checking the spin and moving the vehicle into the tender and the patient as quickly as possible into the water-filled compartment where they could work on it.

But as soon as the immaterial fingers of the tractor beams reached out an equally invisible force seemed to grip Prilicla’s fragile body and shake it furiously.

“Doctor,” said the empath, “the being is radiating extreme fear. It is forcing coherent thought from a mind which is close to panic. It is losing consciousness rapidly, perhaps dying … Look! It is using steering thrust!”

“Cut!” shouted Conway to the tractor beamers. The alien spacecraft, which had almost come to rest, began to spin slowly as vapor jetted from lateral vents in the nose and stern. After a few minutes the jets became irregular, weaker and finally ceased altogether, leaving the vehicle spinning at approximately half its original speed. Prilicla still looked as if its body was being shaken by a high wind.

“Doctor,” said Conway suddenly, “considering the kind of tools these people use I wonder if some kind of psionic force is being used against you-you are shaking like a leaf.”

When it replied Prilicla’s voice was, of course, devoid of all emotion. “It is not thinking directly at anyone, friend Conway,” said the empath. “Its emotional radiation is composed chiefly of fear and despair. Perceptions are diminishing and it seems to be struggling to avoid a final catastrophe …

“Are you thinking what I’m thinking?” said Mannon suddenly.

“If you mean am I thinking of setting the thing spinning at full speed again,” Conway replied. “The answer is yes. But there’s no logical reason for doing so, is there?”

A few seconds later the tractor beam men reversed polarity to increase the vessel’s spin. Almost immediately Prilicla’s trembling ceased and it said, “The being feels much better now-relatively, that is. Its vitality is still very low.”

Prilicla began to tremble again and this time Conway knew that his own feelings of angry frustration were affecting the little being. He tried to make his thinking cooler and more constructive, even though he knew that the situation was essentially the same as it had been when Descartes had first tried to aid the Meatball astronaut, that they were making no progress at all.

But there were a few things he could do which would help the patient, however indirectly.

The vapor escaping from the vehicle should be analyzed to see if it was fuel or simply water from the being’s life-support system. Much valuable data could be gained from a direct look at the patient-even if it was only possible to see it through the wrong end of a periscope, since the vessel did not possess a direct-vision port. They should also seek means of entering the vessel to examine and reassure the occupant before transferring it to the ambulance and the wards.

Closely followed by Lieutenant Harrison, Conway pulled himself along the towing cable toward the spinning ship. By the time they had gone a few yards both men were turning with the rotating cable so that when they reached the spacecraft it seemed steady while the rest of creation whirled around them in dizzying circles. Mannon stayed in the airlock, insisting that he was too old for such acrobatics, and Prilicla approached the vessel drifting free and using its spacesuit propulsors for maneuvering.

Now that the patient was almost unconscious the Cinrusskin had to be close to detect subtle changes in its emotional radiation. But the long, tubular hull was hurtling silently past the little being like the vanes of some tremendous windmill.

Conway did not voice his concern, however. With Prilicla one did not need to.

“I appreciate your feelings, friend Conway,” said Prilicla, “but I do not think that I was born, despite my physiological classification, to be swatted.”

At the hull they transferred from the towing cable and used wrist and boot magnets to cling to the spinning ship, noting that the magnetic grapple placed there by Descartes had seriously dented the hull plating and that the area was obscured by a fog of escaping vapor. Their own suit magnets left shallow grooves in the plating as well. The metal was not much thicker than paper, and Conway felt that if he made a too sudden movement he would kick a hole in it.

“It isn’t quite as bad as that, Doctor,” said the Lieutenant. “In our own early days of space flight — before gravity control, hyper spatial travel and atomic motors made considerations of weight of little or no importance — vehicles had to be built as light as possible. So much so that the fuel contents were sometimes used to help stiffen the structure.

“Nevertheless,” said Conway, “I feel as if I am lying on very thin ice-I can even hear water or fuel gurgling underneath. Will you check the stern, please. I’ll head forward.”

They took samples of the escaping vapor from several points and they tapped and sounded and listened carefully with sensitive microphones to the noises coming from inside the ship. There was no response from the occupant, and Prilicla told them that it was unaware of their presence. The only signs of life from the interior were mechanical. There seemed to be an unusually large amount of machinery, to judge from the sounds they could hear, in addition to the gurgling of liquid. And as they moved toward the extremities of the vessel, centrifugal force added another complication.

The closer they moved toward the bow or stern, the greater was the force tending to fling them off the spinning ship.

Conway’s head was pointing toward the ship’s bow so that the centrifugal force was imposing a negative G on his body. It was not really uncomfortable as yet, however-he felt a little pop-eyed but there was no redding out of vision. His greatest discomfort came from the sight of the ambulance ship, Prilicla and the vast, tubular Christmas tree which was Sector General sweeping around the apparently steady ship’s bows. When he closed his eyes the feeling of vertigo diminished, but then he could not see what he was doing.

The farther forward he went the more power his suit magnets needed to hold him against the smooth metal of the ship’s hull, but he could not increase the power too much because the thin plating was beginning to ripple under the magnets and he was afraid of tearing open the hull. But a few feet ahead there was a stubby, projecting pipe which was possibly some kind of periscope and he began to slide himself carefully toward it. Suddenly he began to slip forward and grabbed instinctively for the pipe as he slithered past.

The projection bent alarmingly in his hand and he let go hurriedly, noticing the cloud of vapor which had formed around it, and he felt himself being flung away like a stone from a slingshot.

“Where the blazes are you, Doctor?” said Mannon. “Last time around you were there, now you aren’t.

“I don’t know, Doctor,” Conway replied angrily. He lit one of his suit’s distress flares and added, “Can you see me now?”

As he felt the tractor beams focus on him and begin to draw him back to the tender, Conway went on, “This is ridiculous! We’re taking far too long over what should be a simple rescue job. Lieutenant Harrison and Doctor Prilicla, go back to the tender, please. We’ll try another approach.”

While they were discussing it Conway had the spacecraft photographed from every angle and had the tender’s lab begin a detailed analysis of the samples Harrison and himself had gathered. They were still trying to find another approach when the prints and completed analyzes reached them several hours later.

It had been established that all the leaks in the alien spacecraft were of water rather than fuel, that the water was for breathing purposes only since it did not contain the usual animal and vegetable matter found in the Meatball ocean samples and that, compared with these local samples, its CO2 content was rather high-the water was, in brief, dangerously stale.

A close study of the photographs by Harrison, who was quite an authority on early space flight, suggested that the flared-out stern of the ship contained a heat shield to which was mounted a solid fuel retro pack. It was now plain that, rather than an unignited final stage, the long cylindrical vehicle contained little more than the life-support equipment which, judging by its size, must be pretty crude. Having made this statement the Lieutenant promptly had second, more charitable thoughts and added that while air-breathing astronauts could carry compressed air with them a water breather could not very well compress its water.

The point of the nose cone contained small panels which would probably open to release the landing parachutes. About five feet astern of this was another panel which was about fifteen inches wide and six feet deep. This was an odd shape for an entry and exit hatch for the pilot, but Harrison was convinced that it could be nothing else. He added that the lack of sophistication shown in the vehicle’s construction made it unlikely that the exit panel was the outer seal of an airlock, that it was almost certainly a simple hatch opening into the command module.

If Doctor Conway was to open this hatch, he warned, centrifugal force would empty the ship of its water-or to be quite accurate, of half its water-within a few seconds. The same force would see to it that the water in the stern section remained there, but it was almost certain that the astronaut was in the nose cone.

Conway yawned furiously and rubbed his eyes. He said, “I have to see the patient to get some idea of its injuries and to prepare accommodation, Lieutenant. Suppose I cut a way in amidships at the center of rotation. An appreciable quantity of its water has already leaked away and centrifugal force has caused the remainder to be pushed toward the nose and stern, so that the middle of the ship would be empty and the additional loss of water caused by my entry would be slight.”

“I agree, Doctor,” said Harrison. “But the structure of the ship might be such that you would open a seam into the water-filled sections-it’s so fragile there is even the danger that centrifugal force might pull it apart.”

Conway shook his head. “If we put a wide, thin-metal band around the waist section, and if the band included a hinged, airtight hatch big enough for a man, we can seal the edges of the band to the ship with fast-setting cement — no welding, of course, as the heat might damage the skin-and rig a temporary airlock over the hatch. That would allow me to get in without—”

“That would be a very tricky job,” said Mannon, “on a spinning ship.”

Harrison said, “Yes. But we can set up a light, tubular framework anchored to the hull by magnets. The band and airlock could be set up working from that. It will take a little time, though.”

Prilicla did not comment. Cinrus skins were notoriously lacking in physical stamina and the little empath had attached itself to the ceiling with six, sucker-tipped legs and had gone to sleep.

Mannon, the Lieutenant and Conway were ordering material and specialized assistance from the Hospital and beginning to organize a work party when the tender’s radioman said, “I have Major O’Mara for you on Screen Two.”

“Doctor Conway,” said the Chief Psychologist, when he was able to see and be seen. “Rumors have reached me that you are trying-and may have already succeeded, in fact-to set up a new record for the length of time taken to transfer a patient from ship to ward. I have no need to remind you of the urgency and importance of this matter, but I will anyway. It is urgent, Doctor, and important. Off.”

“You sarcastic …” began Conway angrily to the already fading image, then quickly controlled his feelings because they were beginning to make Prilicla twitch in its sleep.

“Maybe,” said the Lieutenant, looking speculatively at Mannon, “my leg isn’t properly healed since I broke it during that landing on Meatball. A friendly, cooperative doctor might decide to send me back to Level Two-eighty-three, Ward Four.”

“The same friendly, helpful doctor,” said Mannon dryly, “might decide a certain Earth-human nurse in 283-Four had something to do with your relapse, and he might send you to … say, 241-Seven. There is nothing like being fussed over by a nurse with four eyes and far too many legs to cure a man of baying at the moon.”

Conway laughed. “Ignore him, Harrison. At times his mind is even nastier than O’Mara’s. Right now there isn’t anything more we can do and it has been a long, hard day. Let’s go to bed before we go to sleep.”

Another day went by without any significant progress being made. Because of the need for urgency the team setting up the framework tried to hurry the job, with the result that they lost tools, sections of framework and on several occasions men overboard. The men could be retrieved easily enough by tractor beams, but the tools and framework sections were not equipped with signal flares and were usually lost. Cursing the necessity for having to perform a tricky job of construction on a space going merry-go-round, the men went back to work.

Progress became much slower but a little more certain, the number of dents and furrows put in the spacecraft’s hull by tools and space boots had become uncountable, and the fog of water vapor escaping from the vessel continued to increase.

In a desperate attempt to speed things up, and much against Prilicla’s wishes, Conway tried slowing the craft’s rate of spin again. There were no signs of panic from the occupant this time, the empath reported, because it was too deeply unconscious to care. It added that it could not describe the patient’s emotional radiation to anyone but another empath, but that it was its considered professional opinion that if full spin was not restored the patient would die very shortly.

Next day the framework was completed and work started on fitting the metal band which would take the temporary airlock. While the lock structure was going up Conway and Harrison attached safety lines to the framework and examined the hull. The Lieutenant discovered quite a lot about the steering jets and the circuits to the retro pack, while Conway could only stare baffled at the long, narrow exit hatch or stare through the tiny glass port-it was only a few inches in diameter-which showed little more than a shutter which opened and closed rapidly. And it was not until the following day that the Lieutenant and himself were able to enter the alien spacecraft.

Its occupant was still alive, Prilicla said, but only just.

As expected the waist section of the spacecraft was almost empty of water. Centrifugal force had caused it to collect toward the extremities of the ship, but their spotlights reflected off a dazzling fog of water vapor and droplets which, a quick investigation showed, were being stirred up by the operation of a system of sprocket wheels and chain drives that ran the length of the ship.

Moving carefully so as not to snag a hand between a gear wheel and its chain or inadvertently stick a boot through the fragile hull into space, the Lieutenant moved aft while Conway went forward. They did this so as to ensure that the vessel’s center of gravity stayed as closely as possible to its center of rotation, for any imbalance introduced now would shake loose the framework and probably tear holes in the sides of the ship.

“I realize that the circulation and purification of water requires heavier hardware than an air recycling system,” said Conway, speaking to Harrison and the tender, “but surely there should be a higher proportion of electrical to mechanical systems? I can’t move more than a few yards forward and all I can see are gear wheels and chains drives. The circulation system sets up a strong current, as well, and I’m in danger of being drawn into the works.”

The fine, ever-present mist of bubbles made it difficult to see clearly, but for a moment he caught a glimpse of something which was not part of the machinery-something that was brown and convoluted and with a suggestion of fronds or short tentacles sprouting from it, something organic. The being was hemmed in on all sides by revolving machinery, and it also seemed to be rotating, but there was so little of its body visible that he could not be sure.

“I see it,” said Conway. “Not enough for accurate classification, though. It doesn’t seem to be wearing a pressure suit so this must be its equivalent of shirt-sleeve conditions. But we can’t get at the brute without tearing its ship apart and killing it in the process.” He swore, then went on furiously, “This is ridiculous, insane! I’m supposed to come out here, immobilize the patient, transfer it to a ward and give treatment. But this blasted thing can’t be immobilized without …

“Suppose there is something wrong with its life-support system,” the Lieutenant broke in. “Something which requires gravity, or artificial gravity in the form of centrifugal force, to restore proper function. If we could somehow repair this malfunctioning equipment …

“But why?” said Conway suddenly, as a vague idea that had been lurking at the back of his mind began to creep out into the light. “I mean, why should we assume that it is malfunctioning …” He paused, then said, “We’ll open the valves of a couple of oxygen tanks in here to freshen up the beastie’s air — I mean water. It’s only a first-aid measure, I’m afraid, until we’re in a position to do something more positive. Then back to the tender, I’m beginning to get some odd ideas about this astronaut and I’d like to test them.”

They returned to the control room without taking off their suits, and were met by Prilicla who told them that the patient’s condition seemed a little better although it was still unconscious. The empath added that the reason for this might be that the being was injured and in an advanced state of malnutrition as well as having been close to death through asphyxiation. Conway began telling them about his idea and sketching the alien ship as he talked.

“If this is the center of spin,” he said when the drawing was complete, “and the distance from that point to the pilot’s position is this, and the rate of rotation is this, can you tell me how closely does the apparent gravity in the pilot’s position approach that of Meatball itself?”

“Just a minute,” said Harrison as he took Conway’s pen and began to scribble. A few minutes later-he had taken extra time to double check his calculations-he said, “Very close, Doctor. Identical, in fact.”

“Which means,” said Conway thoughtfully, “that we have here a beastie which can’t, for some very good physiological reason no doubt, live without gravity, for whom weightless conditions are fatal …

“Excuse me, Doctor,” the quiet voice of the radioman cut in. “I have Major O’Mara for you on Screen Two …

Conway felt the idea which was beginning to take shape at the back of his mind being blown into tatters. Spin, he thought furiously, trying to draw it back; centrifugal force, wheels within wheels! But the square, craggy features of the Chief Psychologist were filling the screen and it was impossible to think of anything else.

O’Mara spoke pleasantly-a very bad sign. He said, “Your recent activity has been impressive, Doctor-especially when it took the form of man-made meteorite activity in the shape of dropped tools and structural material. But I’m concerned about your patient. We all are-even, and especially, the Captain of Descartes who has recently returned to Meatball.

“The Captain has run into trouble,” the psychologist continued, “in the shape of three missiles with nuclear warheads which were directed at his ship. One of them went off course and dirtied up a large area of Meatball ocean, and the other two came so close that he had to use full emergency thrust to avoid them. He says that establishing communications and friendly contact with the inhabitants in these circumstances is impossible, that they obviously think he has kidnapped their astronaut for some ghastly purpose of his own, and that the return of the being in a happy and healthy condition is the only means there is of retrieving the situation … Doctor Conway, your mouth is open. Either say something or close it!”

“Sorry, sir,” said Conway absently. “I was thinking. There is something I would like to try, and perhaps you could help me with it — by getting Colonel Skempton’s support, I mean. We’re wasting time out here, I realize that now, and I want to bring the spacecraft inside the hospital. Still spinning, of course — at first, anyway. Cargo Lock Thirty is big enough to take it and is close enough to the water-filled corridor leading to the ward we are preparing for this patient. But I’m afraid the Colonel will be a bit sticky about allowing the spacecraft into the hospital.”

The Colonel was very sticky indeed, despite Conway’s arguments and the support given by O’Mara. Skempton, for the third time, gave a firm and unequivocal negative.

He said, “I realize the urgency of this matter. I fully appreciate its importance to our future hopes of trading with Meatball and I sympathize with your technical problems. But you are not, repeat not, going to bring a chemically powered spacecraft with a live retro pack inside this hospital! If it accidentally ignited we might have a hole blown in the hull which would cause a lethal pressure drop on a dozen levels, or the vehicle might go bulleting into the central computer or gravity-control sections!”

“Excuse me,” said Conway angrily, and turned to the Lieutenant. He asked, “Can you ignite that retro pack, working from the ambulance ship, or disconnect it?”

“I probably couldn’t disconnect it without inadvertently setting it off and burning myself to a crisp,” Harrison replied slowly, “but I know enough to be able to set up a relay which … Yes, we could ignite it from this control room.”

“Go to it, Lieutenant,” said Conway, and returned to the image of Skempton. “I take it, sir, that you have no objection to taking the vessel aboard after its retro pack has been fired? Or to furnishing the special equipment I will need in the cargo lock and ward?”

“The maintenance officer on that level has orders to cooperate,” said Skempton. “Good luck, Doctor. Off.”

While Harrison set up his relay, Prilicla kept an emotional eye on the patient while Mannon and himself worked out the being’s approximate size and weight based on the brief look Conway had had of the astronaut and on the dimensions of its ship. This information would be needed quickly if the special transporter and the rotating operating theater were to be ready in time.

“I’m still here, Doctor,” said O’Mara sharply, “and I have a question. Your idea that the being needs gravity, either normal or artificial, to live I can understand, but strapping it onto an elaborate merry go-round …

“Not a merry-go-round, sir,” said Conway. “It will be mounted vertically, like a ferris wheel.”

O’Mara breathed heavily through his nose. “I suppose you are quite sure that you know what you’re doing, Doctor?”

“Well …” began Conway.

“Ask a stupid question,” said the psychologist, and broke the connection.

It took longer than the Lieutenant had estimated to set up his relay — everything took longer than estimated on this assignment! — and Prilicla reported that the patient’s condition was rapidly worsening. But at last the spacecraft’s retros flared out for the number of seconds necessary to have brought it out of its original orbit and the ambulance ship kept pace with it, spinning it with opposing tractors as soon as thrust disappeared so that the occupant would still have the gravity it needed. There were complications even so. Immediately the retros cut out, panels opened in the nose cone and the landing parachute tumbled out and within seconds the spinning ship had wound the parachute untidily around itself.

The short period of thrust had added to the hull damage as well.

“It’s leaking like a sieve!” Conway burst out. “Shoot another magnetic grapple to it. Keep it spinning and get us to Lock Thirty quick! How is the patient?”

“Conscious now,” said Prilicla, trembling. “Just barely conscious and radiating extreme fear …

Still spinning, the vehicle was maneuvered into the enormous mouth of Lock Thirty. Inside the lock chamber the artificial gravity grids under the deck were set at neutral so that the weightless conditions of space were duplicated there. Conway’s feeling of vertigo, which had been with him since he had first seen the ship, was intensified by the sight of the alien vessel whirling ponderously in the enclosed space, flinging out streamers of coldly steaming water as it spun.

Then suddenly the lock’s outer seal clanged shut, the tractors smoothly checked the ship’s spin as, simultaneously, the artificial gravity of the deck was brought up to Meatball normal. Within a few seconds the spacecraft was resting horizontally on the deck.

“How is it?” began Conway anxiously.

Prilicla said, “Fear … no, extreme anxiety. The radiation is quite strong now-otherwise the being seems all right, or at least improved …

The empath gave the impression of not believing its own feelings.

The spacecraft was lifted gently and a long, low trolley mounted on balloon wheels rolled under it. Water began pouring into the lock chamber from the seal which had opened into the adjacent water-filled section. Prilicla ran up the wall and across the ceiling until it was in position a few yards above the nose of the vessel, and Mannon, Harrison and Conway waded, then swam, in the same direction. When they reached it they clustered around the forward section, ignoring the team which was throwing straps around the hull and fastening it to the trolley prior to moving it into the nearby corridor of the water-breathers, while they cut into the thin hull plating and carefully peeled it away.

Conway insisted on extreme care during this operation so as to avoid damaging the life-support machinery.

Gradually the nose section became little more than a skeleton and the astronaut lay revealed, like a leathery, brown caterpillar with its tail in its mouth that was caught on one of the innermost gear wheels of a giant clock. By this time the vessel was completely submerged, oxygen was being released into the water all around it, and Prilicla was reporting the patient’s feelings as being extremely anxious and confused.

“It’s confused …” said a familiar, irascible voice and Conway discovered O’Mara swimming beside him. Colonel Skempton was dogpaddling along on his other side, but silently. The psychologist went on, “This is an important one, Doctor, in case you’ve forgotten-hence our close personal interest. But now why don’t you pull that glorified alarm clock apart and get the patient out of there? You’ve proved your theory that it needed gravity to live, and we’re supplying that now …

“No, sir,” said Conway, “not just yet …

“Obviously the rotation of the being inside the capsule,” Colonel Skempton broke in, “compensates for the ship’s spin, thus allowing the pilot a stationary view of the outside world.”

“I don’t know,” said Conway doggedly. “The ship’s rotation does not quite match that of the astronaut inside it. In my opinion we should wait until we can transfer it quickly to the ferris wheel, which will almost exactly duplicate module conditions. I have an idea-it may be a pretty wild one-that we aren’t out of the woods yet.”

“But transferring the whole ship into the ward when the patient alone could be moved there in a fraction of the time …

“No,” said Conway.

“He’s the Doctor,” said O’Mara, before the argument could develop further, and smoothly directed the Colonel’s attention to the system of paddle-wheels which kept the water-breathing astronaut’s air circulating.

The enormous trolley, its weight supported in the water to a large extent by air-filled balloon tires, was manhandled along the corridor and into the tremendous tank which was one of the combined theater/wards of the hospital’s water-breathing patients. Suddenly there was another complication.

“Doctor! It’s coming out!”

One of the men swarming around the nose section must have accidentally pushed the astronaut’s ejection button, because the narrow hatch had swung open and the system of gears, sprocket wheels and chain drives was sliding into new positions. Something which looked like three five foot diameter tires was rolling toward the opening.

The innermost tire of the three was the astronaut while the two on each side of it had a metallic look and a series of tubes running from them into the central, organic tire-probably food storage tanks, Conway thought. His theory was borne out when the outer sections stopped just inside the hatch and the alien, still trailing one of the feeding tubes, rolled out of its ship. Still turning it began to fall slowly toward the floor eight feet below.

Harrison, who was nearest, tried to break its fall but could only get one hand to it. The being tipped over and hit the floor flat on its side. It bounced slowly just once and came to rest, motionless.

“It is unconscious again, dying! Quickly, friend Conway!”

The normally polite and self-effacing empath had turned the volume of its suit radio to maximum so as to attract attention quickly. Conway acknowledged with a wave-he was already swimming toward the fallen astronaut as fast as he could-and yelled at Harrison, “Get it upright, man! Turn it!”

“What …” began Harrison, but he nevertheless got both hands under the alien and began to lift.

Mannon, O’Mara and Conway arrived together. With four of them working on it they quickly lifted the being into an upright position, but when Conway tried to get them to roll it, it wobbled like a huge, soggy hoop and tended to fold in on itself. Prilicla, at great danger to life and its extremely fragile limbs, landed beside them and deafened everyone with details of the astronaut’s emotional radiation-which was now virtually nonexistent.

Conway yelled directions to the other three to lift the alien to waist height while keeping it upright and turning. Within a few seconds he had O’Mara pulling down on his side, Mannon lifting on his and the Lieutenant and himself at each flank turning and steadying the great, flaccid, ring-shaped body.

“Cut your volume, Prilicla!” O’Mara shouted. Then in a quieter, furious voice he snarled, “I suppose one of us knows what we’re doing?”

“I think so,” said Conway. “Can you speed it up-it was rotating much faster than this inside its ship. Prilicla?”

“It … it is barely alive, friend Conway.”

They did everything possible to speed the alien’s rotation while at the same time moving it toward the accommodation prepared for it. This contained the elaborate ferris wheel which Conway had ordered and a watery atmosphere which duplicated the soup of Meatball’s oceans. It was not an exact duplicate because the material suspended in the soup was a nonliving synthetic rather than the living organisms found in the original, but it had the same food value and, because it was nontoxic so far as the other water breathers who were likely to use the ward were concerned, the astronaut’s quarters were contained by a transparent plastic film rather than metal plating and a lock chamber. This also helped speed the process of getting the patient into its ward and onto the wheel.

Finally it was in position, strapped down and turning in the direction and at the same velocity as its “couch” on the spacecraft. Mannon, Prilicla and Conway attached themselves as close to the center of the wheel and their rotating patient as possible and, as their examination proceeded, theater staff, special instruments, diagnostic equipment and the very special, thought-controlled “tool” from Meatball added themselves or were attached to the framework of the wheel and whirled up and over and around through the nearly opaque soup.

The patient was still deeply unconscious at the end of the first hour.

For the benefit of O’Mara and Skempton, who had relinquished their places on the wheel to members of the theater staff, Conway said, “Even at close range it is difficult to see through this stuff, but as the process of breathing is involuntary and includes ingestion, and as the patient has been short of food and air for a long time, I’d prefer not to work in clear, food-free water at this time.”

“My favorite medicine,” said Mannon, “is food.”

“I keep wondering how such a life-form got started,” Conway went on. “I suppose it all began in some wide, shallow, tidal pool-so constituted that the tidal effects caused the water to wash constantly around it instead of going in and out. The patient might then have evolved from some early beastie which was continually rolled around in the shallows by the circular tides, picking up food as it went. Eventually this prehistoric creature evolved specialized internal musculature and organs which allowed it to do the rolling instead of trusting to the tides and currents, also manipulatory appendages in the form of this fringe of short tentacles sprouting from the inner circumference of its body between the series of gill mouths and eyes. Its visual equipment must operate like some form of coeleostat since the contents of its field of vision are constantly rotating.

“Reproduction is probably by direct fission,” he went on, “and they keep rolling for every moment of their lives, because to stop is to die.”

“But why?” O’Mara broke in. “Why must it roll when water and food can be sucked in without it having to move?”

“Do you know what is wrong with the patient, Doctor?” Skempton asked sharply, then added worriedly, “Can you treat it?”

Mannon made a noise which could have been a snort of derision, a bark of laughter or perhaps merely a strangled cough.

Conway said, “Yes and no, sir. Or, in a sense, the answer should be yes to both questions.” He glanced at O’Mara to include the psychologist and went on, “It has to roll to stay alive-there is an ingenious method of shifting its center of gravity while keeping itself upright by partially inflating the section of its body which is on top at any given moment. The continual rolling causes its blood to circulate-it uses a form of gravity feed system instead of a muscular pump. You see, this creature has no heart, none at all. When it stops rolling its circulation stops and it dies within a few minutes.

“The trouble is,” he ended grimly, “we may have almost stopped its circulation once too often.”

“I disagree, friend Conway,” said Priicla, who never disagreed with anyone as a rule. The empath’s body and pipe stem legs were quivering, but slowly in the manner of a Cinrusskin who was being exposed to emotion of a comfortable type. It went on, “The patient is regaining consciousness quickly. It is fully conscious now. There is a suggestion of dull, unlocalized pain which is almost certainly caused by hunger, but this is already beginning to fade. It is feeling slightly anxious, very excited and intensely curious.

“Curious?” said Conway.

“Curiosity is the predominating emotion, Doctor.”

“Our early astronauts,” said O’Mara, “were very special people, too.

It was more than an hour later by the time they were finished, medically speaking, with the Meatball astronaut and were climbing out of their suits. A Corps linguist was sharing the ferris wheel with the alien with the intention of adding, with the minimum of delay, a new e-t language to the memory banks of the hospital’s translation computer, and Colonel Skempton had left to compose a rather tricky message to the Captain of Descartes.

“The news isn’t all good,” Conway said, grinning with relief despite himself. “For one thing, our ‘patient’ wasn’t suffering from anything other than malnutrition, partial asphyxiation and general mishandling as a result of being rescued — or rather by — by Descartes. As well, it shows no special aptitude in the use of the thought-controlled tools and seems completely unfamiliar with the things. This can only mean that there is another intelligent race on Meatball. But when our friend can talk properly I don’t think there will be much difficulty getting it to help us find the real owners-it doesn’t hold any grudges for the number of times we nearly killed it, Prilicla says, and … and I don’t know how we managed to come out of this so well after all the stupid mistakes we made.”

“And if you are trying to extract a compliment from me for another brilliant piece of deductive reasoning, or your lucky guess,” said O’Mara sourly, “you are wasting your time and mine …

Mannon said, “Let’s all have lunch.”

Turning to go, O’Mara said, “You know I don’t eat in public-it gives the impression that I am an ordinary human being like everyone else. Besides, I’ll be too busy working out a set of tests for yet another so-called intelligent species …
