“Kervenser to the bridge for standby! I’m going outside. Research, give me outside conditions!”
“One moment. Captain.” The pause was brief before the voice resumed, “Temperature 77; pressure 26.1; wind from 21, steady at 200 cables per hour; oxygen fraction standard at 0.0122.”
“Thanks. That doesn’t seem too bad.”
“No. With your permission, I’ll come out with you to get surface samples. May we set up the drill? We can get cores to a fair depth in less than ten hours.”
“That will be all right. I may be outside before you get to the lock, if you take time to collect the drill gear, but you are cleared outside when ready. Tell Kervenser the number of your party, for the log.”
“Thank you, Captain. We’ll be there right away.” Dondragmer relaxed at his station; he would not, of course, leave the bridge until his relief appeared, even with the engines stopped. Kervenser would be some minutes in arriving, since he would have to turn his current duties over to a relief of his own. The wait was not bothersome, however, since there was plenty to think about. Dondragmer was not the worrying type (the Mesklinite nervous system does not react to uncertainty in that way) but he did like to think situations out before he lived them. The fact that he was some ten or twelve thousand miles from help if the Kwembly were ever crippled was merely background, not a special problem. It did not differ essentially from the situation he had faced for most of his life on Mesklin’s vast seas. The principal ripple on his normally placid self-confidence was stirred up by the machine he commanded. It resembled in no way the flexible assemblage of rafts which was his idea of a ship. He had been assured that it would float if occasion arose; it actually had floated during tests on distant Mesklin where it had been built. Since then, however, it had been disassembled, loaded into shuttle craft and lifted into orbit around its world of origin, transferred in space to an interstellar flier, shifted back to another and very different shuttle after the three-parsec jump, and brought to Dhrawn?s surface before being reassembled. Dondragmer had personally supervised the disassembly and reconstruction of the Kwembly and her sister machines, but the intervening steps had not been carried out under his own eye. This formed the principal reason for his wanting to go outside now; high as was his opinion of Beetchermarlf and the rest of his picked crew, he liked firsthand knowledge. He did not, of course, mention this to Kervenser when the latter reached the bridge. It was something which went without saying. Anyway, the first officer presumably felt the same himself. “Maintenance checks are under way. The researchers are going out to sink a well, and I’m going out to look things over,” was all Dondragmer said as he resigned his station. “You can signal me with outside lights if necessary. It’s all yours.” Kervenser snapped two of his nippers light-heartedly. “I’ll ride it, Don. Enjoy yourself.” The captain left by way of the still open hatch which had admitted his relief, telling himself as he went that Kervenser wasn’t as casual as he sounded. Four decks down and sixty feet aft of the bridge was the main air lock. Dondragmer paused several times on the way to talk to members of his crew as they worked among the cords, beams, and piping of the Kwembly’s interior. By the time he reached the lock four scientists were already there with their drilling gear, and had started to don their air suits. The captain watched critically as they wriggled their long bodies and numerous legs into the transparent envelopes, made the tests for tightness, and checked their hydrogen and argon supplies. Satisfied, he gestured them into the lock and began suiting up himself. By the time he was outside the others were well on with setting up their apparatus. He glanced at them only briefly as he paused at the top of the ramp leading from lock to ground. He knew what they were doing and could take it for granted, but he could never be that casual about the weather. Even as he latched the outer lock portal behind him, he was looking at as much of the sky as the towering hull of his command permitted. The darkness was deepening very, very slowly as Dhrawn’s two-month rotation carried the feeble sun farther below the horizon. As at home, the horizon itself seemed to be somewhat above his level of sight all around. The gravity-squeezed atmosphere responsible for this effect would also set the stars twinkling violently when they became visible. Dondragmer glanced toward the bow, but the twin stars which guarded the south celestial pole, Fomalhaut and Sol, were still invisible. A few cirrus clouds showed above, drifting rapidly toward the west. Evidently the winds a thousand or two feet above were opposed to the surface ones, as was usual during the daytime. This might change shortly, Dondragmer knew; only a few thousand miles to the west was country in which the setting of the sun would make a greater temperature change than it did here, and there might be weather changes in the next dozen hours. Exactly what sort of changes, was more than his Mesklinite sailor background, even fortified with alien meteorology and physics, enabled him to guess. For the moment, though, all seemed well. He made his way down the ramp to the snow and a hundred yards to the east, partly to make sure of the rest of the sky and partly to get an overall view of his command before commencing a detailed inspection. The western sky was no more threatening than the rest, and he favored it with only a brief glance. The Kwembly looked just as usual. To a human being it would probably have suggested a cigar made of dough and allowed to settle on a flat table for a time. It was slightly over a hundred feet in length, between twenty and twenty-five in breadth, and its highest point was nearly twenty feet above the snow. Actually there were two such points; the upper curve of the hull, about a third of the way back, and the bridge itself. The latter was a twenty-foot crosspiece whose nearly square outlines somewhat spoiled the smooth curves of the main body. It was almost at the bow, permitting helmsman, commander, and conning personnel to watch the ground as they traveled almost to the point where the forward trucks covered it. The flat bottom of the vehicle was nearly a yard off the snow, supported on an almost continuous set of tread-bearing trucks. These were individually castered and connected by a bewildering rigging of fine cables, allowing the Kwembly to turn in a fairly short radius with reasonably complete control of her traction. The trucks were separated from the hull proper by what amounted to a pneumatic mattress, which distributed traction and adapted to minor ground irregularities. A caterpillarlike figure was making its way slowly along the near side of the land-cruiser, presumably Beetchermarlf continuing his inspection of the rigging. Twenty yards closer to the captain the short tower of the core drill had been erected. Above, clinging to the holdfasts which studded the hull but could hardly be seen at the captain’s distance, other crew members were climbing about as they inspected the seams for tightness. This, to a Mesklinite, was a nerve-stretching job. Acrophobia was a normal and healthy state of mind to a being reared on a world where polar gravity was more than six hundred times that of Earth, and even “home” gravity a third of that. Dhrawn’s comparatively feeble pull, scarcely thirteen hundred feet per second squared, took some of the curse off climbing, but hull inspection was still the least popular of duties. Dondragmer crawled back across the hard-packed mixture of white crystals and brown dust, interrupted by occasional sprawling bushes, and made his way up the side to help out with the job. The great, curved plates were of boron fiber bonded with oxygen-and fluorine-loaded polymers. They had been fabricated on a world none of the Mesklinites had ever seen, though most of the crew had had dealings with its natives. The human chemical engineers had designed those hull members to withstand every corrosive agent they could foresee. They fully realized that Dhrawn was one of the few places in the universe likely to be even worse in this respect than their own oxygen-and-water world. They were quite aware of its gravity. They had all these factors in mind when they synthesized the hull members and the adhesives which held them together: both the temporary cements used during the testing on Mesklin and the supposedly permanent ones employed in reassembling the vehicles on Dhrawn. Dondragmer had every confidence in the skill of those men, but he could not forget that they had not faced and never expected to face the conditions their products were fighting. These particular parachute packers would never be asked to jump, though that analogy would have been lost on a Mesklinite. Much as the captain respected theory, he very well knew the gap between it and practice, so he devoted full attention to examining the joints between the great hull sections. By the time he had satisfied himself that they were still sound and tight, the sky had become noticeably darker. Kervenser, in response to a rap on the outside of the bridge and a few gestures, had turned on some of the outside lights. By their aid the climbers finished their work and made their way back onto the snow. Beetchermarlf appeared from under the great hull and reported his tiller lines in perfect shape. The workers at the drill had recovered several feet of core, and were taking this into the laboratory as soon as each segment was obtained, in view of the ambient temperature. Actually the local “snow” seemed to be nearly all water at the surface, and therefore safely below its melting point, but no one could be sure how true this would be deeper down. The artificial light made the sky less noticeable. The first warning of changing weather was a sudden gust of wind. The Kwembly rocked slightly on her treads, the tiller lines singing as the dense air swept past them. The Mesklinites were not inconvenienced. In Dhrawn’s gravity blowing them away would have been a job for a respectable tornado. They weighed about as much as a lifesized gold statue would have on Earth. Dondragmer, digging his claws reflexively into the dusty snow, was not bothered by the wind; but he was much annoyed at his own failure to notice earlier the clouds which accompanied it. These had changed from the fleecy cirrus perhaps a thousand feet above to broken stratus-type scud at half that height. There was no precipitation yet, but none of the sailors doubted that it would come soon. They could not guess, however, what form it would
