Derelict by Alan E. Nourse

John Sabo, second in command, sat bolt upright in his bunk, blinking wide-eyed at the darkness. The alarm was screaming through the Satellite Station, its harsh, nerve-jarring clang echoing and re-echoing down the metal corridors, penetrating every nook and crevice and cubicle of the lonely outpost, screaming incredibly through the dark sleeping period. Sabo shook the sleep from his eyes, and then a panic of fear burst into his mind. The alarm! Tumbling out of his bunk in the darkness, he crashed into the far bulkhead, staggering giddily in the impossible gravity as he pawed about for his magnaboots, his heart pounding fiercely in his ears. The alarm! Impossible, after so long, after these long months of bitter waiting— In the corridor he collided with Brownie, looking like a frightened gnome, and he growled profanity as he raced down the corridor for the Central Control.

Frightened eyes turned to him as he blinked at the bright lights of the room. The voices rose in a confused, anxious babble, and he shook his head and swore, and ploughed through them toward the screen. “Kill that damned alarm!” he roared, blinking as he counted faces. “Somebody get the Skipper out of his sack, pronto, and stop that clatter! What’s the trouble?”
