Chapter 1

The Quedak lay on a small hilltop and watched a slender jet of light descend through the sky. The feather-tailed jet was golden, and brighter than the sun. Poised above it was a glistening metallic object, fabricated rather than natural, hauntingly familiar. The Quedak tried to think what it was.

He couldn’t remember. His memories had atrophied with his functions, leaving only scattered fragments of images. He searched among them now, leafing through his brief scraps of ruined cities, dying populations, a blue-water-filled canal, two moons, a spaceship...

That was it. The descending object was a spaceship. There had been many of them during the great days of the Quedak.

Those great days were over, buried forever beneath the powdery sands. Only the Quedak remained. He had life and he had a mission to perform. The driving urgency of his mission remained, even after memory and function had failed.

As the Quedak watched, the spaceship dipped lower. It wobbled and sidejets kicked out to straighten it. With a gentle explosion of dust, the spaceship settled tail first on the arid plain.

And the Quedak, driven by the imperative Quedak mission, dragged itself painfully down from the little hilltop. Every movement was an agony. If he were a selfish creature, the Quedak would have died. But he was not selfish. Quedaks owed a duty to the universe; and that spaceship, after all the blank years, was a link to other worlds, to planets where the Quedak could live again and give his services to the native fauna.

He crawled, a centimeter at a time, and wondered whether he had the strength to reach the alien spaceship before it left this dusty, dead planet.

Captain Jensen of the spaceship Southern Cross was bored sick with Mars. He and his men had been here for ten days. They had found no important archeological specimens, no tantalizing hints of ancient cities such as the Polaris expedition had discovered at the South Pole. Here there was nothing but sand, a few weary shrubs, and a rolling hill or two. Their biggest find so far had been three pottery shards.

Jensen readjusted his oxygen booster. Over the rise of a hill he saw his two men returning.

“Anything interesting?” he asked.

“Just this,” said engineer Vayne, holding up an inch of corroded blade without a handle.

“Better than nothing,” Jensen said. “How about you, Wilks?”

The navigator shrugged his shoulders. “Just photographs of the landscape.”

“OK,” Jensen said. “Dump everything into the sterilizer and let’s get going.”

Wilks looked mournful. “Captain, one quick sweep to the north might turn up something really--”

“Not a chance,” Jensen said. “Fuel, food, water, everything was calculated for a ten-day stay. That’s three days longer than Polaris had. We’re taking off this evening.”

The men nodded. They had no reason to complain. As the second to land on Mars, they were sure of a small but respectable footnote in the history books. They put their equipment through the sterilizer vent, sealed it, and climbed the ladder to the lock. Once they were inside, Vayne closed and dogged the hatch, and started to open the inside pressure door.

“Hold it!” Jensen called out.

“What’s the matter?”

“I thought I saw something on your boot,” Jensen said. “Something like a big bug.”

Vayne quickly ran his hands down the sides of his boots. The two men circled him, examining his clothing.

“Shut that inner door,” the captain said. “Wilks, did you see anything?”

“Not a thing,” the navigator said. “Are you sure, Cap? We haven’t found anything that looks like animal or insect life here. Only a few plants.”

“I could have sworn I saw something,” Jensen said. “Maybe I was wrong ... Anyhow, we’ll fumigate our clothes before we enter the ship proper. No sense taking any chance of bringing back some kind of Martian bug.”

The men removed their clothing and boots and stuffed them into the chute. They searched the bare steel room carefully.

“Nothing here,” Jensen said at last. “OK, let’s go inside.”

Once inside the ship, they sealed off the lock and fumigated it. The Quedak, who had crept inside earlier through the partially opened pressure door, listened to the distant hiss of gas. After a while he heard the jets begin to fire.

The Quedak retreated to the dark rear of the ship. He found a metal shelf and attached himself to the underside of it near the wall. After a while he felt the ship tremble.

The Quedak clung to the shelf during the long, slow flight through space. He had forgotten what spaceships were like, but now memory revived briefly. He felt blazing heat and freezing cold. Adjusting to the temperature changes drained his small store of vitality, and the Quedak began to wonder if he was going to die.

He refused to die. Not while there was still a possibility of accomplishing the Quedak mission.

In time he felt the harsh pull of gravity, and felt the main jets firing again. The ship was coming down to its planet.

After a routine landing, Captain Jensen and his men were taken to Medic Checkpoint, where they were thumped, probed and tested for any sign of disease.

Their spaceship was lowered to a flatcar and taken past rows of moonships and ICBMs to Decontamination Stage One. Here the sealed outer hull was washed down with powerful cleansing sprays. By evening, the ship was taken to Decontamination Stage Two.

A team of two inspectors equipped with bulky tanks and hoses undogged the hatch and entered, shutting the hatch behind them.

They began at the bow, methodically spraying as they moved toward the rear. Everything seemed in order; no animals or plants, no trace of mold such as the first Luna expedition had brought back.

“Do you really think this is necessary?” the assistant inspector asked. He had already requested a transfer to Flight Control.
