The Invincible

encouraging nodding by the shimmering lights of the remote control steering, like bits of mother-of-pearl. Then colorful signals lit up like a Christmas tree: they indicated that the burntout rocket stages had been jettisoned. Finally the rainbow effect created by the constant flickering and shimmering was blotted out by a stark white rectangle. This was the sign that the satellite had reached its orbit. In the center of this glittering white area a small gray island emerged, gradually condensing its vague outlines to form the number 67, the altitude at which the satellite was circling the planet.

Rohan quickly checked out the orbital parameters, but perigee and apogee were close to the values calculated beforehand. There was nothing else for him to do here. He compared the time aboard the Invincible, 18:00, with current local time: it was 23:00. For a brief moment he closed his eyes; he looked forward to this excursion to the seashore, for he preferred working on his own. He felt hungry and tired. Rohan deliberated whether he should take a pep pill, but then decided to have a real meal. As he rose from his seat he realized how exhausted he actually felt. The momentary shock caused by this discovery gave him a new burst of strength. Rohan took the elevator down to the mess hall. His crew was already there waiting for him: the two drivers of the air-cushioned hover trucks. He was fond of the one name Jarg, because of his pleasant disposition. There were also the oceanographer Fitzpatrick and his two colleagues Broza and Koechlin. They were just finishing supper as Rohan ordered some hot soup and helped himself to bread and a few bottles of nonalcoholic beer which he took from an automatic dispenser built in the wall. He placed everything on a tray and walked over to the dining table. At this moment a slight tremor shook the floor. The Invincible had launched another satellite.

The commander had not been in favor of any nocturnal expeditions. Shortly before sunrise, at 5:00 Am. local time, they started out on the journey. They employed the usual precautionary measures, advancing in the painfully slow marching order that was generally known as the “funeral procession.” A group of energo-robots led the way while others brought up the rear. They had erected an ellipsoid force field for the protection of the entire group, for the all-purpose vehicles, the cross-country jeeps containing radar and radio installations, the mobile kitchen, the trailer with airtight living quarters, and the small carriage on caterpillar tracks on which their laser beam sender had been mounted.

Rohan and his three experts climbed into the energo-robot at the front of the train. It was a rather tight squeeze, but this way they had at least the illusion of a relatively normal ride. The entire train moved at the speed of the slowest vehicles — the energo-robots — which did not contribute to the men’s comfort. The caterpillar tracks groaned and crunched through the sand. The turbo engines maintained a steady hum, reminding Rohan of a huge swarm of persistent flies. Cool air blew from the air conditioning duct that opened directly behind their seats. The energo-robot rocked back and forth like a big sloop making its way through heavy seas. After a while the black needle of the Invincible sank below the horizon. For some time they drove across the monotonous desert while the sun rose, blood red and cold.

The landscape changed. There was no longer so much sand. Instead rocky shelves rose at a slant from the ground. Many detours were necessary. Conversation was impossible because of the noisy engines and the oxygen masks covering their faces. Conscientiously the men scanned the horizon, again and again finding the same picture: huge rock piles and big chunks of well-weathered stones. Finally the ground began to slope downwards. At the bottom of a basin-shaped valley they discovered a small brook with a narrow trickle of water that glittered in the red light of the dawn. Both banks were lined with wide deposits of round, polished stones, indicating that the brook occasionally must carry considerable amounts of water.

They halted briefly and examined the water. It was limpid but rather hard, and contained ferric oxide and tiny traces of sulphide.

They continued their march at a faster pace than before, since the caterpillar tracks could make better headway on the rocky ground. To the west rose low rocky cliffs. The last vehicle maintained communication with the Invincible. The radar antennae kept turning; the observers sat in front of their radar screens, constantly adjusting their headsets and chewing grains of energy concentrate. Once in a while a stone was flung out from beneath the turbo-drive vehicles as if by a tiny tornado, propelling it high up the stony slopes. Then their way was blocked by softly arching hills. Without slowing down they picked up a few rock samples. Fitzpatrick called out to Rohan that the gravel-like soil might be of organic origin.

Finally, as they sighted the blue-black surface of the ocean, they also found some limestone formations. They drove toward the shore. The ground was now covered with small, flat stones over which the vehicles proceeded noisily. The hot vapors from the motors, the screeching of the caterpillar chains, the hum of the engines were all instantly stifled as they halted suddenly about one hundred yards offshore. The green-gray ocean stretched out ahead of them, looking no different than the Atlantic Ocean on Earth.

Now a rather complicated maneuver had to be executed: the energo-robot in front of the column had to advance deep into the water in order to maintain the protective energy screen above the whole group. The machine was made watertight, then it rolled into the waves, steered by remote control from another robot. The first robot sank slowly deeper and deeper, disappearing underneath the surface, and could be seen only dimly as a dark spot. Then, obeying a radio signal, the immersed colossus pushed its Dirac emitter above the surface of the water. As soon as the energy field had become stabilized, arching an invisible hemisphere over a part of both the shore and the ocean in front of it, the men could start their examinations.

The salinity of this ocean was slightly less than that of terrestrial sea water, but the results of the analysis were anything but sensational. Two hours later they knew little more than before, so they steered two television probes far out over the ocean, observing their paths on television sets. Not until the probes had disappeared on the horizon did the crew receive signals that were of any interest to them. Some living organisms inhabited the ocean; they resembled fish. As the probes approached, the creatures scatterd with enormous speed, seeking shelter in the depths of the ocean. Sonic depth finders located the first sign of organic life on Regis 150 yards below the surface of the ocean.

Broza insisted on catching one of the fish. The probes pursued the shadows as they flitted about in the darkness of the ocean, shooting electrical charges at them. But the fish were incredibly agile; it took many misses before finally one of the creatures was stunned and could be grabbed by hooks lowered from the probes. The crew recalled the probe immediately to shore.

In the meantime, Koechlin and Fitzpatrick had guided another probe over the ocean, collecting samples of fibers that were drifting in the deeper layers of the sea. The men believed them to be a type of local algae. Finally they sent the probe all the way down to the ocean floor, which at this point reached a depth of 250 yards. Down below were strong currents that made remote-control steering rather difficult. The probe was constantly pushed off course and collided all the time with the rock heaps on the ground. With great effort some of the stones could finally be rolled over. Just as Koechlin had suspected, a whole colony of tiny cilia-covered creatures had been hiding underneath the shelter of the big stones.

After the two probes had safely returned to their base, the biologists began their task. In the meantime a hut had been erected where they could take off the bothersome respirator masks. Rohan, Jarg and the five other men ate their first hot meal that day.

For the rest of the day they were busy collecting mineral specimens, examining the radioactivity of the ocean floor, measuring the amount of insultation and carrying out the manifold tasks that were irksome yet had to be performed with accuracy if they wanted to obtain reliable results.

By dusk everything that they had set out to do had been achieved. Rohan felt a sense of accomplishment as he stepped to the microphone to answer Horpach’s call from the Invincible. He reported that the ocean was full of living organisms, all of which avoided coming anywhere close to the shore regions. Nothing unusual had been detected when they had dissected the one fish they had caught. The evolution of life on Regis III must have been going on for approximately several hundred million years. They had also discovered considerable amounts of green algae; this should account for the presence of the oxygen in the atmosphere. There was the same division of observed organic forms as on Earth and other planets, namely into flora and fauna. Also the skeletal structure of the vertebrates seemed to be typical. However, one organ had been found in the fish specimen for which no corresponding terrestrial structure was known to the examining biologists. This seemed to be a special organ of sense that reacted strongly to minute variations in a magnetic field.

Horpach ordered the crew to return immediately to the spacecraft. He closed the conversation by reporting an important item of news: they had apparently succeeded in discovering the place where the lost Condor had landed.
