Major Operation sg-3 Read online

  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 section
s-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 c
heck 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.”
