"O.K., Carl. You're the balance wheel in this outfit. If you must aberrate, lean outward a bit, will you? I'd hate to singe the pants off of a couple of billion Telfans whilst trying to save their lives."

"I'll keep an eye on it," promised Carlson.

"Eye?" grunted Peters. "He means ear. Or has Carlson got his semicircular canals in his eyes?"

Hammond interrupted with a gloating shout. "Mac! We're in! Ninety-one percent. Pure, crystalline Silicon-acetyldiethyl-sulfanomid. And the charge is almost equal to the galactic mean; meaning that the stuff is stable."

McBride nodded and said into the communicator: "Our half is did, boys. All that stands between we-all and Telfu is a stinking, one-hundred mile satellite. Frankly, I'm agin it!"

Peters did not answer McBride. He shouted, his voice strained with excitement: "Here comes Soaky now, around the edge of Telfu. This is it, gang. Bore him deep and give him Hell!"

Sandra Drake sat down on the edge of a hard bench and took a deep breath. With her free hand, she rubbed her eyes and pushed the stray hair out of them. Her eyes were red-rimmed and puffed with lack of sleep. She stretched and took a longing look at the surface of the hard bench; one of those looks that was calculating not the hardness of the bench but wondering if she could catch forty winks without having trouble call her away again. She decided not. She knew herself, and she knew that as long as she kept going she could stay awake, but if she slowed down for a moment, she'd drop off and nothing would awaken her. And forty winks would actually make her feel worse than no sleep at all.

Outside of the window, dawn was just breaking. It was a strange dawn, an alien sunrise, but one that was nothing new to Sandra Drake. Sirius II was just above the horizon, but almost lost in the mists because of its low radiation. Sirius I was not above the horizon yet, but his strong radiation was coloring the sky blue-gray.

Sandra looked out of the window at the graying sky above. Carefully and hopefully she scanned it but she was not surprised that nothing was there for her to see. The idea of doing away with a hundred-mile satellite was too much, even for McBride, Hammond, and the rest of their gang. A hundred miles of celestial body was not large as celestial bodies go, but against man's futile efforts it was simply vast.

In all of the man-made works on Terra, Pluto, Venus, Mars, and Luna, considerably less than the volume of a hundred-mile sphere had been moved. Affected, perhaps, but not man-moved; the pile-up of rivers behind a dam could not be counted.
