“That’s only true where velocities close to the speed of light are concerned, when the spaceship is something like a ray of light and can only move in a straight line or along the so-called curve of equal tension.”
“If I’ve understood you correctly we have to aim our Tantra light ray straight at the solar system.”
“That’s where the great difficulty of space travel comes in. It’s practically impossible to aim directly at any star although we make all the corrective calculations imaginable. Throughout the entire journey we have to compute the accumulating error and constantly change the course of the ship so that no automatic piloting is possible. Our position now is a dangerous one. We have nothing left to start another acceleration going so that a halt or even a considerable reduction in speed after this acceleration would be certain death. Look, the danger is here — in area 344 4- 2U that has never been explored. Here there are no stars, no inhabited planets, nothing is known except the gravitational field — there is its edge. We’ll wait for the astronomers before we make the final decision — after the fifth circle we’ll wake up everybody but in the meantime….” The commander rubbed his temples and yawned.
“The effect of the sporamin is wearing off,” exclaimed Nisa, “you can go to sleep!”
“Good, I’ll be all right here, in this chair. Suppose a miracle happens… just one sound from them!”
There was something in Erg Noor’s voice that sent Nisa’s heart palpitating with her love for him. She wanted to take that stubborn head of his, press it to her breast and stroke the dark hair with its prematurely grey threads.
Nisa got up, placed the reference sheets carefully together and turned out the light, leaving only a dull green glow that illuminated the instrument panels and the clocks. The spaceship was travelling quite quietly in a complete vacuum as it described its gigantic curve. The auburn-haired navigator silently took her place at the “brain” of the giant ship. The instruments, tuned to a particular note, hummed softly; the slightest disorder made them sing false. Today, however, the quiet humming kept on the right note. On rare occasions she heard soft blows, like the sounds of a gong — that was the auxiliary planet motor switching in to keep the ship truly on her curve. The powerful anameson motors were silent. The peace of a long night hung over the sleepy ship as though no serious danger threatened her and her inhabitants. At any moment the long-awaited call signal would be heard in the loudspeaker and the two ships would begin to check their unbelievably rapid flight, would draw closer on parallel courses and would at last so equalize their speeds that they would be as good as lying still beside each other. A wide tubular gallery would connect the two ships and Tantra would regain her tremendous strength.
Deep down in her heart Nisa was calm, she had faith in her commander. Five years of travel had not seemed either long or tiring. Especially since Nisa had begun to love…. But even before that the absorbingly interesting observations, the electronic recordings of books, music and films gave her every opportunity to increase her fund of knowledge and not feel the loss of beautiful Earth, that tiny speck of dust lost in the depths of the infinity of darkness. Her fellow-travellers were people of great erudition and then, when her nerves were exhausted by a surfeit of impressions or lengthy, strenuous work, there was continued sleep. Sleep was maintained by attuning the patient to hypnotic oscillations and, after certain preliminary medical treatment, big stretches of time were lost in forgetfulness and passed without leaving a trace. Nisa was happy because she was near the man she loved. The only thing that troubled her was the thought that others were having a harder time, especially Erg Noor. If only she could… no, what could a young and still very green astronavigator do, compared with such a man! Perhaps her tenderness, her constant fund of good will, her ardent desire to give up everything in order to make easier that tremendous labour would help.
The commander of the expedition woke up and raised his sleep-heavy head. The instruments were humming evenly as before, there were still the occasional thuds of the planetary motors. Nisa Greet was at the instruments, bending slightly over them, the shadows of fatigue on her young face. Erg Noor cast a glance at the clock showing spaceship time and in a single athletic bound leaped out of the deep chair.
“I’ve been asleep fourteen hours! And you didn’t wake me, Nisa! That’s….” Meeting her radiant glance he cut himself short. “Off to bed at once!”
“May I sleep here, like you did?” asked the girl. She took a hurried meal, washed herself and dropped into the deep armchair. Her flashing hazel eyes, framed in dark rings, were stealthily following Erg Noor as he took his place at the instrument panels after a refreshing wave bath and a good meal. He checked up the indicators on the electronics communications protector and then began to walk up and down with rapid strides.
“Why aren’t you sleeping?” he asked the navigator. She shook her red curls that were by then in need of clipping — women on extra-terrestrial expeditions did not wear long hair.
“I was thinking…” she began hesitantly, “and now, when we are faced with great danger I bow my head before the might and majesty of man who has penetrated to the stars, far, far into the depths of space! Much of this is customary for you, but I’m in the Cosmos for the first time. Just think of it, I’m taking part in a magnificent journey through the stars to new worlds!”
Erg Noor smiled wanly and rubbed his forehead. “I shall have to disappoint you, or rather, I must show you the real measure of our might. Look…” he stopped beside a projector and on the back wall of the control tower the glittering spiral of the Galaxy appeared. Erg Noor pointed to a ragged outer branch of the spiral composed of sparse stars looking like dull dust and scarcely perceptible in the surrounding darkness.
“This is a desert area in the Galaxy, an outer fringe poor in light and life, and it is there that our solar system is situated and where we are at present. That branch of the Galaxy stretches, as you can see, from Cygnus to Carina and, in addition to being far removed from the central zone, it contains a dark cloud, here…. Just to travel along that one branch of the Galaxy would take our Tantra 40,000 independent years. To cross the empty space that separates our branch from our neighbours would take 4,000 years. So you see that our flights into the depths of space are still nothing more than just marking time on our own ground, a ground with a diameter of no more than fifty light years! How little we should know of the Universe if it were not for the might of the Great Circle. Reports, images and ideas transmitted through space that is unconquerable in man’s brief span of life reach us sooner or later, and we get to know still more distant worlds. Knowledge is constantly piling up and the work goes on all the time!”
Nisa listened in silence.
“The first interstellar flights…” continued Erg Noor, still lost in thought. “Little ships of low speed with no powerful protective installations… and people in those days lived only half as long as we do — that was the period of man’s real greatness!”
Nisa jerked up her head as she usually did when she disagreed.
“‘And when new ways of overcoming space have been discovered and people don’t just force their way through it like we do, they’ll say the same about you — those were the heroes who conquered space with their primitive methods!”
The commander smiled happily and held out his hand to the girl.
“They’ll say it about you, too, Nisa!”
“I’m proud to be here with you!” she answered, blushing. “And I’m prepared to give up everything if I can only travel into the Cosmos again and again!”
