“Go on, please do, I’ve never heard anything so interesting,” Nisa begged him, but the commander was implacable. He brought a pulsating hypnotizer and, either because of his impelling eyes or the sleep-producing apparatus, the girl was soon fast asleep and did not wake up until the day before they were to enter the sixth circle. By the cold look on the commander’s face Nisa Greet realized that Algrab had not shown up.

“You woke up just at the right time!” he said as soon as Nisa had taken her electric and wave baths and returned ready for work. “Switch on the animation music and light.

For everybody!”

Swiftly Nisa pressed a row of buttons sending intermittent bursts of light accompanied by a specific music of low, vibrant chords that gradually increased in intensity, to all the cabins where members of the Cosmic expedition were sleeping. This initiated the gradual awakening of the inhibited nervous system to bring it back to its normal active state. Five hours later all the members of the expedition gathered in the control tower; they had by then fully recovered from their sleep and had taken food and nerve stimulants.

News of the loss of the auxiliary spaceship was received in different ways by different people. As Erg Noor expected, the expedition was equal to the occasion. Not a word of despair, not a glance of fear. Pour Hyss, who had not shown himself particularly brave on Zirda heard the news without a tremor. Louma Lasvy, the expedition’s young physician, went slightly pale and secretly licked her dry lips.

“To the memory of our lost comrades!” said the commander as he switched on the screen of a projector showing Algrab, a photograph that had been taken before Tantra took off. All rose to their feet. On the screen one after another came the photographs of the seven members of Algrab’s crew, some serious, some smiling. Erg Noor named each of them in turn and the travellers gave him the farewell salute. Such was the custom of the astronauts. Spaceships that set off together always carried photographs of all the people of the expedition. When a ship disappeared it might keep travelling in Cosmic space for a long time with its crew still alive. But this made no difference, the ship would never return. There was no real possibility of searching for the ship and rendering it aid. Minor faults never, or seldom, occurred and were easily repaired, but a serious break-down in the machinery had never been successfully repaired in the Cosmos. Sometimes ships, like Parus, managed to send a last message, but in the majority of cases such messages did not reach their destination on account of the great difficulty of directing them. The Great Circle had, for thousands of years, been investigating exact routes for its transmissions and could vary them by directing them from planet to planet. The spaceships were usually in unexplored areas where the direction for a message could only be guessed.

There was a conviction amongst astronauts that there existed in the Cosmos certain neutral fields or zero areas in which all radiation and all communications sank like stones in water. Astrophysicists, however, regarded the zero areas to be nothing more than the idle invention of Cosmic travellers who were, in general, inclined to monstrous fantasies.

After that sad ceremony and a very short conference, Erg Noor turned Tantra in the direction of Earth and switched on the anameson motors. Forty-eight hours later they were switched off again and the spaceship began to approach its own planet at the rate of 21,000 million kilometres in every twenty-four hours. The journey back to the Sun would take about six terrestrial, or independent, years. Everybody was busy in the control tower and in the ship’s combined library and laboratory where a new course was being computed and plotted on the charts.

The task was to fly the whole six years and use anameson only for purposes of correcting the ship’s course. In other words the spaceship had to be flown with as little loss of acceleration as possible. Everybody was worried about the unexplored area 344 +2U that lay between the Sun and Tantra. There was no way of avoiding it: on both sides of it, as far as the Sun, lay belts of free meteoroids and, apart from that, they would lose velocity in turning the ship.

Two months later the computation of the line of flight had been completed. Tantra began to describe a long, flat curve.

The wonderful ship was in excellent condition and her speed was kept within the computed limits. Now nothing but time, about four dependent years, separated the ship from its home.

Erg Noor and Nisa Creet finished their watch and, dead tired, started their period of long sleep. Together with them two astronomers, the geologist, biologist, physician and four engineers departed into temporary forgetful-ness.

The watch was taken over by an experienced astronavigator, Pel Lynn, who was on his second expedition, assisted by astronomer Ingrid Dietra and electronic engineer Kay Bear who had volunteered to join them. Ingrid, with Pel Lynn’s consent, often went away to the library adjoining the control tower. She and her old friend, Kay Bear, were writing a monumental symphony. Death of a Planet, inspired by the tragedy of Zirda. Pel Lynn, whenever he grew tired of the hum of the instruments and his contemplation of the black void of the Cosmos, left Ingrid at the control desk and plunged into the thrilling task of deciphering puzzling inscriptions brought from a planet in the system of the nearest stars of the Centaur whose inhabitants had mysteriously quit it. He believed in the success of his impossible undertaking….

Twice again watches were changed, the spaceship had drawn ten billion kilometres nearer Earth and still the anameson motors had only been run for a few hours.

One of Pel Lynn’s watches, the fourth since Tantra had left the place where she was to have met Algrab, was coming to an end.

Ingrid Dietra, the astronomer, had finished a calculation and turned to Pel Lynn who was watching, with melancholy mien, the constant flickering of the red arrows on the graded blue scales of the gravitation meters. The usual sluggishness of psychic reaction that not even the strongest people could avoid made itself felt during the second half of the watch. For months and years the spaceship had been automatically piloted along a given course. If anything untoward had happened, something that the electronic machines were incapable of dealing with, it would have meant the loss of the ship, for human intervention could not have saved it since the human brain, no matter how well trained it may be, cannot react with the necessary alacrity.

“In my opinion we are already deep in the unknown area 344 — 2U. The commander wanted to take over the watch himself when we reached it,” said Ingrid to the astronavigator. Pel Lynn glanced up at the counter that marked off the days.

“Another two days and we change watches. So far there doesn’t seem to be anything to worry about. Shall we see the watch through?”

Ingrid nodded assent. Kay Bear came into the control tower from the stern of the ship and took his usual seat beside the equilibrium mechanism. Pel Lynn yawned and stood up.

“I’ll get some sleep for a couple of hours,” he said to Ingrid. She got up obediently and went forward to the control desk.

Tantra was travelling smoothly in an absolute vacuum.

Not a single meteoroid, not even at a great distance, had been registered by the super-sensitive Voll Hoad detectors. The spaceship’s course now lay somewhat to one side of the Sun, about one and a half flying years. The screens of the forward observation instruments were of an astounding blackness, it seemed as though the spaceship was diving into the very heart of universal darkness. The side telescopes still showed needles of light from countless stars.
