The straight edge of Uranus was getting hazier. Even the fainter stars shone through, spangling it. A bell jangled and the pale green segment narrowed as the steel meteor panels began to close in front of the spaceshield. Soon there was only a narrow vertical ribbon of green—bright green as it narrowed to a thread—then for a few seconds only blackness except for the dim red and blue beads and semi-circles, just beyond the captain, of the board. Then the muted interior cabin lights glowed on. Jackson droned: "They and their ships come from very far away, from the edge. If this is the continuum, they come from the ... discontinuum, where they don't have stars but something else and where gravity is different. Their ships came from the edge on a gust of fear with the other ships, and our brothers came with it though they didn't want to...." And now Grunfeld thought he began to feel it—the first faint thrill, less than a cobweb's tug, of weight. The cabin wall moved sideways. Grunfeld's suit had begun to revolve slowly on a vertical axis. For a moment he glimpsed Jackson's dark profile—all five suits were revolving in their framework. They locked into position when the men in them were facing aft. Now at least retinas wouldn't pull forward at high-G decel, or spines crush through thorax and abdomen. The cabin air was cold on Grunfeld's forehead. And now he was sure he felt weight—maybe five pounds of it. Suddenly aft was up. It was as if he were lying on his back on the spaceshield. A sudden snarling roar came through his suit from the beams bracing it. He lost weight, then regained it and a little more besides. He realized it was their torpedo taking off, to skim by Uranus in the top of the atmosphere and then curve inward the little their chem fuel would let them, homing toward the Enemy. He imaged its tiny red jet over the great gray-green glowing plain. Four more would be taking off from the other ships—the fleet's feeble sting. Like a bee's, just one, in dying. The cheekpieces and foreheadpiece of Grunfeld's suit began to close on his face like layers of pliable ice. Jackson called faintly, "Now I understand. Their ship—" His voice was cut off. Grunfeld's ice-mask was tight shut. He felt a small surge of vigor as the suit took over his breathing and sent his lungs a gush of high-oxy air. Then came a tingling numbness as
