The Karella hung poised deep in Earth’s shadow, well beyond measurable air pressure. The spherical compass tuned to the transmitter on the planet far below pointed in a direction that would have been straight down had there been any weight. Ordon Lee was reading, with an occasional glance at his beloved indicator board whenever a light blinked. This was fairly often, for Ken and Feth had put the testing of cold-armor on a mass-production basis. One of the suits had already returned and been checked; Feth was now in the open air lock, clad in an ordinary space suit, detaching the second from the cargo rings and putting the third in its place. He was in touch with Ken, at the torpedo controls, by radio. The scientist was holding the torpedo as well as he could partly inside the lock, which had not been designed for such maneuvers and was not large enough for the full length of the projectile. Feth was having his troubles from the same fact, and the lock-obstruction light on Lee’s board was flashing hysterically.
With the torpedo once more plunging toward the dark surface below, things quieted down a little — but only a little. Feth brought the second suit inside, necessarily closing the outer door in the process and occasioning another pattern of colored light to disturb the pilot’s reading. Then there was nothing but the fading proximity light as the torpedo receded, and the burden of divided attention was shifted to Ken. He had to stay at his controls, but he wanted desperately to see what Feth was doing. He already knew that the first of the suits was wearable — its interior temperature had dropped about forty degrees, which represented an actual heat loss his own metabolism could easily make up; and there was a governor on the heater unit which Feth had deliberately set down so that the heat loss should be measurable. With that limitation removed, he should be as comfortable on the Planet of Ice as anyone could expect to be while encased in nearly three hundred pounds of metal.
Knowing this, he was less worried about the second suit; but he found that he was still unable to concentrate completely on the job in hand. He was quite startled when a buzzer sounded on his own board, which proved to be announcing the fact that his torpedo had encountered outside pressure. As Ken had not reduced its speed to anything like a safe value, he was quite busy for a while; and when he had finally landed the messenger — safely, he hoped — Feth had finished his work. There were now two usable suits.
That removed the greatest load from the minds of both scientist and mechanic, and they were not too disappointed when the third unit failed its test. Ken had a suspicion of the reason — Feth found that leakage had occurred at leg and “sleeve” joints, which would have been put under considerable stress by high acceleration. He did not volunteer this idea, and Feth asked no questions. Ken had an uneasy idea that the mechanic with the rather surprising chemical and physical background might have figured the matter out for himself, however.
This worry, if it could be dignified by such a name, was quickly submerged in the flurry of final preparations for the descent. Ordon Lee still refused flatly to lower his ship into the heat-trap of Earth’s atmosphere, even after the success of two of the suits; it would therefore be necessary for Ken to ride down as the empty armor had done — clamped to the outside of a torpedo. The attachments would have to be modified so that he could manipulate them himself, and that took a little time. Ken ate a good meal, and took the unusual precaution of drinking — the Sarrians manufactured nearly all the liquid they needed in their own tissues.
If the scientist felt any slight doubts as he stepped into the metallic bulk which was to be his only shield for the next few hours from the ghastliest environment he could imagine, his pride prevented them from showing. He was silent as Feth carefully dogged the upper section in place — entry was effected through the top — and listened with a tiny stethoscope to each of the equalizer pumps as they were turned on. Satisfied, he nodded approval at the armored scientist, and Ken reached out, seized a stanchion with one of his handlers, and pulled his personal tank into motion toward the air lock. He had to wait in the corridor while Feth redonned his own suit, and then patiently inside the lock while the mechanic carefully attached the armor to the hull of the torpedo. Lee had finally become helpful, and was holding the projectile inside the lock against the pull of the meteor repellers, which he still refused to turn off for an instant.
Even when the outer door closed between Ken and the rest of the Livable space within several million miles, he managed to keep his self control. He was now used to weightlessness, fortunately; the endless-fall sensation has serious mental effects on some people. Even the relative emptiness of the surrounding space he could stand, since he could see enough objects to keep himself oriented. There were about as many stars visible here as near his home planet, since two hundred parsecs mean little in the size of the galaxy.
In fact, he retained his calm until his eyes as well as his sense of balance agreed to tell him he was falling. The Karella had long since vanished behind — or above — him. The sun was in almost the same direction, since there had been no discussion needed to settle that the landing should be made on the day side of the planet. Rather more had been needed before the same old landing place had been selected — Ken, of course, wanted to see the natives, but even his scientific curiosity had been tempered with caution. Feth, regarding the trip chiefly as another test of the armor, had been rather against natives as an added complication; but curiosity had won out. Ken was falling toward the homing transmitter at which the trading was done, with the understanding that he would be carried a little to the west, as before — he was willing to meet “his” native, but did not want to interfere more than necessary with trade. He realized, of course, that the creatures probably moved around, but he resolutely declined to think about the probable results if the one he had frightened had met the traders; he regarded it as profitless guesswork, which it certainly would have been.
The result of all the discussion, however, meant that he could see clearly the expanding world below — it felt like below, since Feth was now slowing the torpedo’s descent He could not see the torpedo at all easily, as his armor was facing away from it and the back view ports in the helmet were too close to the hull for real vision. He was beginning to feel, therefore, like a man hanging from the ledge of a high roof on a rope of questionable strength. If his vocal apparatus had been as closely connected with his breathing mechanism as is that of a human being, his state of mind would certainly have been betrayed by the radio to the listeners above. As it was they could not hear his tense breathing, and he endured his terror in silence and alone. It was probably just as well; Ordon Lee’s reaction would hardly have been a sympathetic one, and whatever helpful feeling Feth might have had he would not have been likely to express aloud.
There was air around him now — at least the gaseous mixture this world used for air. It was whistling upward, audible even through the armor. He could not be much more then five miles from the ground, and the descent was still rapid — too rapid, he was beginning to feel. As if in answer to the thought, his weight increased abruptly, and he knew that Feth far above had added power. With an effort greater than he had thought himself capable of making, Ken wrenched his attention from the rapid expansion of the landscape below and the creaking of the taut chains above, and concentrated on details. Once started, this proved easy, for there was more that was fantastic around him than mere temperature.
He could not see too far, of course. Eyes whose greatest sensitivity lies in the blue and near ultra-violet work are at a considerable disadvantage in Earth’s hazy atmosphere. Still, the ground below was taking on detail.
It was rough, as they had deduced. Even though mountains do not show to best advantage from overhead, Ken was experienced enough to judge that these were quite respectable heights by Sarrian standards. The surface was buried in a riot of color, largely varying shades of green, brown, and gray. Here and there a patch of metallic sheen reminded him disquietingly of the vast, smooth areas where the mysteriously hostile intelligences of the planet dwelt. If these were outposts — but they had never interfered with the trading torpedoes which had been descending for years in this same area, Ken told himself.
As he dropped lower, he saw that some of the gray elevations were of remarkable shape and form — many of them were actually broader above than lower down. He was quite low before he could see that these objects were not part of the landscape, but were actually suspended in the air. The only clouds he had ever seen were the vast dust storms raised by Sarr’s furious winds, but he judged that these must be of somewhat similar nature. Probably the particles were smaller, to permit them to remain in suspension — a planet this cold could hardly have very strong winds. He described the phenomena as minutely as he could to the listeners above. Feth reported that he was putting Ken’s broadcasts on record, and added some more pertinent information.
“Your descent has been almost stopped, now. You are about one mile above the transmitter, and a few hundred feet higher above the place where the atmosphere tests were made. Do you want to go straight down now, or stay there and observe for a while?”
“Down with moderate speed, please. It is not possible to see too far, and I’d like to get down to where real details are visible. It seems to be mountainous country — I’ll try to guide you in landing me near some peak, so that I can observe for a reasonable distance from a stable spot.”
“All right. You’re going down.” Two or three minutes passed silently; then Ken spoke again.
“Are you moving me horizontally?”
“No. You are already away from over the transmitter— three or four miles.”
“Then this atmosphere has stronger currents than I expected. I am drifting visibly, though not rapidly. It’s rather hard to specify the direction — the sun is not very far from straight up, and the torpedo hides it.”
“When you’re nearly down, give me the direction with respect to the torpedo’s orientation. I’ll stop you before you touch.”
Gradually details grew clearer. The greenness seemed to be a tangled mass of material somewhat resembling chemical growths Ken had prepared in various solutions; he tentatively identified it as plant life, and began to suspect what had caused the crackling sound when the test torpedo had been landed.
Standing out from the green were areas quite obviously of bare rock. These seemed to be located for the most part at and near the tops of the mountains; and with infinite care Ken directed his distant pilot in an approach to one of these. Finally, hanging motionless twenty feet above a surface which even in this relatively dim light was recognizable as rock, he gave the order to lower away.
Six feet from the ground, he had the machine stopped again, and carefully released the leg chains. The lower part of his armor dropped, almost touching; a word into the microphone brought the metal feet into contact with the ground. Releasing one of the upper chains caused him to swing around, still leaning at a sharp angle with one side up toward the supporting hull. By a species of contortionism he contrived to make a workable tripod of his legs and the rear prop of the armor, and at last released the final chain. He was standing on the Planet of Ice, on his own two feet.
He felt heavy, but not unbearably so. His extreme caution not to land in a recumbent position was probably well founded — it was very unlikely that he could have raised himself and the armor to a standing posture with his own muscles in this gravity. Walking was going to be difficult, too — possibly even dangerous; the rock was far from level.
This, of course, was not the principal matter. For several minutes after he had severed connections with the torpedo, Ken made no attempt to move; he simply stood where he was, listening to the almost inaudible hum of his circulation motors and wondering when his feet would start to freeze. Nothing seemed to happen, however, and presently he began to take a few cautious steps. The joints of his armor were still movable; evidently the zinc had not yet frozen.
The torpedo had drifted away from overhead; apparently a slight wind was blowing. At Ken’s advice, Feth brought the machine to the ground. Even with his fear lost in curiosity, Ken had no intention of becoming separated by any great distance from his transportation. Once assured that it was remaining in place, he set to work.
A few minutes’ search located several loose rock fragments. These he picked up and placed in the torpedo, since anything might be of some interest; but he principally wanted soil — soil in which things were visibly growing. Several times he examined rock specimens as closely as he could, hoping to find something that might resemble the minute plants of Planet Four; but he failed utterly to recognize as life the gray and black crustose lichens which were actually growing on some of the fragments.
The landscape was not barren, however. Starting a few hundred yards from his point of landing, and appearing with ever-increasing frequency as one proceeded down the mountainside, there were bushes and patches of moss which gradually gave way to dwarfed trees and finally, where the rock disappeared for good beneath the soil, to full grown firs. Ken saw this, and promptly headed for the nearest clump of bushes. As an afterthought, he told Feth what he was doing, so that the torpedo could be sent along. There was no point, he told himself, in carrying all the specimens back up the hillside.
Progress was quite difficult, since a gap a foot wide between rocks presented a major obstacle to the armor. After a few minutes of shuffling punctuated with frequent pauses for rest, he remarked:
“The next time, we’d better have longer shoulder chains. Then I can hang right side up from the torpedo, and be spared all this waddling.”
“That’s a thought,” replied Feth. “It certainly will be easy enough. Do you want to come back up now and make the change, or collect a few things first?”
“Oh, I’ll stay a while, now that I’m here. I haven’t much farther to travel to get to these plants, if they are plants. The darned things are green, at least partly. I suppose, though, that objectively speaking there should be nothing surprising about that. Well, here we go again.”
He lifted his prop from the ground and shuffled forward once more. Another minute or two sufficed to bring him within reach of the strange growth. It was only about a foot high, and he was even less able to bend down to it than he had been on Planet Four; so he extended a handler to seize a branch. The results were a trifle startling.
The branch came away easily enough. There was no trouble about that. However, before he had time to raise it to his eyes a puff of smoke spurted from the point where the handler was touching it, and the tissue in the immediate neighborhood of the metal began to turn black. The memories aroused by this phenomenon caused Ken to drop the branch, and he would undoubtedly have taken a step backward had the armor been less cumbersome. As it was, he remembered almost instantly that no gas could penetrate his metal defenses, and once more picked up the bit of vegetation.
The smoke reappeared and grew thicker as he lifted it toward his face port, but he had several seconds to examine its structure before the smoldering wood burst into flame. Although this startled him almost as much as the earlier phenomenon had, he retained his hold on the fragment. He watched with interest as the main branch curled, blackened, glowed, and flamed away, the drier leaves following suit while the green ones merely browned slightly. He made an effort to capture some of the traces of ash that remained when the process was completed, but all he was able to save were some bits of charcoal from the less completely burned portions. This he also stowed in the torpedo, Feth guiding the little vessel over to him in response to spoken directions.
A bit of soil, scraped up from beneath the plant, smoked but did not burn. Ken obtained a number of airtight cans from the cargo compartment of the torpedo and spent some time scooping bits of soil up in these. He also compressed some of the air into a cylinder, using a small piston-type pump from which Feth had carefully removed all traces of lubricant. It leaked a trifle, but its moving parts moved, which was a pleasant surprise.
“There,” said Ken, when the task was completed. “If there are any seeds in that earth, we should be able to build a little vivarium and find out at least something about this life and its needs.”
“Do you have a balance between makers and eaters?” asked Feth. “Suppose these plants are all — what would you call them? oxidizers? — and you don’t have the corresponding reducers. I should think you’d need a balance of some sort, with any sort of life — otherwise you’d have perpetual motion.”
“I can’t tell that, of course, until we try. Still, I might go down this mountain a little farther and try to pick up a wider variety. There are still some empty cans.”
“Another point — I don’t recall your making any arrangement to keep them at the proper temperature. I know they’re almost as cold as outer space, but there’s a difference between almost and all the way.”
“We’ll leave the cans in the torpedo until we get back to One. With no air, they’ll change temperature very slowly, and we can leave the torpedo somewhere on the twilight zone of One where it’ll stay about the right temperature until we can build a chamber with thermostats and a refrigerator — it won’t be very large; I have only a couple of cubic yards of air.”
“All right, I guess you win. If it doesn’t work, it will be small loss anyway. Are your feet getting cold yet?”
“Not so far — and believe me, I’m looking for it!”
“I’m not sure I believe you. I have a pretty good idea of where most of your attention is. Have you seen any animal life? I’ve heard the old buzzing once or twice.”
“Have you? I hadn’t noticed it. All I can hear comes from the mike in the torpedo, so I should get anything you do.”
“I told you where your attention was. Well, I’ll call you if I hear it again.” He fell silent, and Ken resumed his laborious journey downhill. With frequent rests, he finally succeeded in filling and sealing all his containers and depositing them in the cargo space of the torpedo. He was interrupted once by Feth, who reported that the buzzing was again audible; but even though Ken himself could hear it when he listened, he was unable to find the source. Flies are not very large creatures, and the light was very dim anyway by Sarrian standards. Since there was nothing very appetizing even for a fly in the cargo compartment above which the microphone was located, the buzzing presently ceased.
Ken took a final look at the landscape, describing everything as completely as he could so that the record being made far above would be useful. The peaks stood out far more prominently now, since some of them were higher than he was. By ignoring the vegetation with which their slopes were clothed and imagining that it was sunset just after a particularly good dust storm, he was even able to find something almost homelike in the scene — there were times when even Sarr’s blue-white sun could look as dull as the luminary of this icy world. At such times, of course, there was always a wind which would put Earth’s wildest hurricane to shame, and the silence around him was out of place on that score; but for just a moment his imagination was able to carry him across two hundred parsecs of emptiness to a world of warmth and life.
He came to himself with a little start. This place was nothing like home — it wasn’t exactly dead, but it should be; dead as the vacuum of space it so greatly resembled. Its cold was beginning to creep into him, mentally in the form of a return of the horror he had felt the first time he had seen the planet and physically by a slight ache in his feet. Even the engineering miracle he was wearing could not keep out the fingers of the cold indefinitely. He started to call Feth, to have the torpedo lifted so that he could get at the chains and clamps; but the request was not uttered.
As suddenly as it had done a few days before, a human voice cut sharply through the stillness of the Planet of Ice.
