Structures on Earth were erected by special machines called embryotecti because they worked on the principle of the cybernetic development of the living organism. It goes without saying that the molecular structure of the living organism, effected by the hereditary cybernetic mechanism, was immeasurably more complicated.
Living organisms, however, could only grow in the conditions provided by warm solutions of ionized molecules while the embryotecti usually worked in polarized streams of electricity or light or in a magnetic field. The markings and keys on all the component parts painted in radioactive thallium gave the correct orientation to the machines assembling them precisely and at high speed. At the great height of the satellite there were not and could not be any such machines. The assembly of the satellite was an old-fashioned building job employing human hands. Despite the dangers involved the work seemed so interesting that it attracted thousands of volunteers. The psycho-physiological stations were scarcely able to examine the flood of volunteers desirous of informing the Council of their readiness to venture into interplanetary space.
Darr Veter reached the foundations of the solar machines that were arranged fanwise round a huge hub containing the artificial gravity apparatus and joined the battery he was carrying on his back to the terminals of the test circuit. A simple melody could be heard in the phones of his space helmet. Then he connected in parallel a glass plate with the thin gold lines of a drawing on it. It produced the same melody. Darr Veter turned a couple of vernier scales until points of time coincided and listened to make sure there was no difference in the melody or even in the tone of the tuning. An important part of the future satellite had been assembled faultlessly. They could now begin the erection of the radiation electric motors. Darr Veter straightened shoulders that were bent wearily under the weight of a spacesuit worn over a long period and turned his head to the right and to the left. The movement caused a creaking of the upper vertebrae that immobility in the space helmet had made stiff. It was a good thing that, so far, Darr Veter had proved impervious to the psychoses that affect those who work outside the terrestrial atmosphere — these included ultra-violet sleeping sickness and infrared madness — otherwise he would not have been able to bring his worthy mission to a successful conclusion.
Soon the outer walls of the hull would protect the workers from the effects of a feeling of loneliness in the Cosmos, alone over an abyss that had neither sky nor ground!
Altai sent out a small rescue rocket that shot past the construction job like an arrow. This was a tug going to fetch the automatic rockets carrying only cargo and halting at a given altitude. Just in time! The bundle of rockets, people, machines and building materials, floating in space, was passing over to the night side of the planet. The tug rocket returned pulling behind it three long, gleaming, blue fish-like rockets that weighed a hundred and fifty tons on Earth (without fuel).
The rockets joined their fellows around the assembly platform. In one leap Darr Veter reached the other side of the hull and was soon amongst the technicians supervising the unloading who were gathered in a circle. They were discussing the plan for the night work. Darr Veter consented but insisted that all personal batteries be changed for freshly charged ones with sufficient energy to keep the spacesuits warm for thirty hours and at the same time supply the electric lamps, air filters and radiotelephones.
The whole construction job was plunged in darkness as though it were at the bottom of the sea but the soft zodiacal light from the Sun’s rays dispersed by the gases of the atmospheric zones still lit up the skeleton of the future satellite that was gripped in a frost of 180 degrees C. The superconductivity of the metal now hindered them even more than it did by day. The slightest amount of wear in the insulation of the instruments, batteries or accumulators surrounded the nearby objects with a blue glow from current flowing along their surfaces and which could not be canalised in any given direction.
The profound darkness of outer space came together with increasing cold. The stars burned fiercely like dazzlingly bright blue needles in the sky. The invisible and inaudible flight of the meteoroids was even more awe-inspiring at night. In the currents of the atmosphere over the dark globe down below there were variously coloured clouds of electric glow, spark discharges of tremendous length and sheets of dispersed light thousands of kilometres long. Down below, in the upper layers of the atmosphere there were gales of greater fury than anything known on Earth. Vigorous movements of energy continued in an atmosphere saturated by the radiations of the Sun and the Cosmos and made communication with the planet extremely difficult.
Suddenly something changed in that tiny world lost in the darkness and fearful cold. Darr Veter did not immediately realize that the planetship had switched on its searchlights. The darkness had become even blacker, the burning stars grew dull, leaving the platform and the hull in a sea of bright white light that divided them off from the gloom. A few minutes later Altai reduced the voltage and the light turned yellow and was less intense.
The planetship was economizing current from its accumulators. The squares and ellipses that went to make up the walls of the hull, the latticed trusses that reinforced the structure, the cylinders and pipes of the reservoirs again moved about, finding their places in the skeleton of the satellite as though in daylight.
Darr Veter felt for a cross beam, took hold of the handles of a roller car running on a ropeway, and with one hard push of his feet sailed up to Altai. Right in front of the planetship’s hatch he pressed the brake lever in his hand and halted just in time to prevent his crashing into a closed door.
The air-lock was not kept at normal terrestrial pressure in order not to lose too much air with the coming and going of such a large number of workers. Darr Veter kept on his spacesuit until he was in a second, auxiliary air-lock, where he unscrewed his space helmet and battery.
Flexing a body that was weary of the spacesuit, Darr Veter walked firmly along the deck of the ship, enjoying a return to almost normal gravity. The artificial gravitation of the planetship worked constantly. It was inexpressibly pleasant to feel yourself standing firmly on the ground as a man should stand and not be like a flea floundering in an unsteady, treacherous gulf! Soft light and warm air and a comfortable chair tempted him to stretch out in it and relax without having to think. Darr Veter was experiencing the pleasures of his distant ancestors that had once astonished him in old novels. It was in this way that people entered a warm house, a mud hut or a felt tent after long journeys through cold deserts, wet forests or icy mountains. And now as then a thin wall separated him from a huge, dangerous world, hostile to man, a wall that retained the warmth and light, gave him a chance to rest, gather fresh strength and think over what he was to do next.
Darr Veter did not yield to the temptation of armchair and book. He had to contact Earth — the light burning all night at that height might cause alarm amongst those who were keeping the satellite under observation. It was also necessary to warn Earth that reinforcements would be needed ahead of time.
There was good communication that day and Darr Veter talked with Grom Orme on the TVP and not in coded signals; the TVP was an extremely powerful one, such as was fitted to every spaceship. The old chairman was pleased with the progress made and said he would immediately see about new workers and extra materials.
