Worst of all, perhaps, was the horrible loneliness that oppressed him. He was too close to Outside now. He was the only living thing in a place never meant for human life. The ghastly bleakness of the asteroid sank like knife-blades into his mind, searing it coldly. There was no relief when he looked up. The distant sun, with its corona, was infinitely far away. The rest of the sky held stars, remote, not twinkling as on Earth, but shining with a cold intensity, a pale fury relentless and eternal. In the light the heat seared him through his armor; in the shadows he shivered with cold.
He went on, sick with hate, seeking the unknown thing that had taken Doug.
The boy was a poet, a dreamer, a fool, easy victim for the terror that haunted the asteroid.
Exhausted, he turned back. His air supply was running low, and there was no sign of either Doug or Hastings. He headed for the ship....
It was further than he had thought. He sighted it at last, beneath a towering stalagmite that thrust up into the harsh sunlight, and his steps quickened. Why hadn't he thought to bring extra cylinders of oxygen?
The lock stuck under his gloved, awkward fingers; he wrenched at it savagely. At last the great valve swung open. He went through the airlock, opened his visiplate, and took great breaths of the fresher air. Oxygen cylinders were racked near by; he swung several into position on his back and clamped them into place. He gulped more caffeine tablets.
Some instinct made him turn and look back through the port. Over the uneven ground a space-suited figure was staggering, a quarter of a mile distant....
Arnsen's heart jumped. In one swift motion he clamped shut his visiplate and leaped for the airlock. It seemed an eternity before he was outside, leaping, racing, straining toward the man who had fallen helpless, a motionless shadow amid the glare. Doug? Hastings?
It was O'Brien, his young face gray with exhaustion and flushed with oxygen-thirst. For a moment Arnsen thought the boy was dead. He thrust one arm under O'Brien's back, lifting him; with the other hand he fumbled at an auxiliary air-hose, thrusting it into the valve in O'Brien's chin-plate as he ripped away the useless hose. Oxygen flowed into the boy's suit.
