He made his way back to the bridge and resumed his position in the command chair. The executive officer monitored the two technicians as they left the airlock and followed Harbin’s orders. Within half an hour they reported that they had successfully discharged the electrostatic field that held the rocks of their armor shield tightly around the hull of the ship.
“Some of the rocks are floating loose now,” the weapons tech reported, her voice tense. “Most of ’em are holding in place against the hull, though.”
“Good,” Harbin said tightly. “Come back aboard.”
“Yes, sir.” He could hear the relief in their voices. They were technicians, not trained astronauts. Working outside was not a chore they enjoyed.
While they were wriggling out of their space suits back at the airlock, Harbin commanded his pilot to turn and commence a high-speed run at the Astro ships. The other two HSS vessels were to remain on their courses.
The two technicians struggled back into their seats as Samarkand’s fusion engines accelerated the ship to a full g and then even beyond. Harbin heard metal groaning and creaking as the trio of Astro ships grew visibly bigger in the main screen.
The loosened rocks of the rubble shield were being pushed mechanically by the bulk of the accelerating ship. They were no longer held to the hull by the electrostatic field. Harbin heard thumps and bangs as some of the rocks separated entirely from the ship, but most of them obediently followed Newton’s laws and hung on the ship’s hull.
Harbin could see the Astro warships deploying to meet his solo attack. He felt sweat trickling down his ribs, cold and annoying. Once we let loose the rocks we’ll have no protection against their lasers, he knew. But they’ll be too busy to fire on us. He hoped.
“Decelerate,” he ordered. “Reduce to one-half g.”
The pilot tried to slow the ship smoothly, but still Harbin felt as if his insides were being yanked out of him. The comm tech moaned like a wounded creature and the entire ship seemed to creak and complain, metal screeching against metal.
As the ship slowed, though, the thousands of rocks of her rubble shield—fist-sized and smaller—kept on moving in a straight line, blindly following their own inertia as they hurtled toward the Astro vessels.
“Turn one hundred eighty degrees,” Harbin snapped.
The sudden lurching turn was too much for the comm tech; she retched and slumped over the armrest of her chair. Samarkand was no racing yacht. The ship turned slowly, slowly toward the right. Some of the remaining rocks ground against the hull, a dull grating sound that made even the pilot look up with wide, frightened eyes.
Harbin paid no attention to anything but the main screen. The Astro vessels were in the path of a speeding avalanche of stones as most of Samarkand’s erstwhile shielding came plunging toward them.
“Keep the stones between us and them,” Harbin told the pilot. “We can still use them to shield us.”
The display screen was filled with the rubble now. Harbin saw a brief splash of laser light as one of the Astro warships fired into the approaching avalanche. With his armrest keyboard he widened the scope of the display.
The Astro captains knew what had happened to Gormley, too. For a heartstopping few seconds they maintained their formation, but then their nerve broke and the two escorting warships scattered, leaving the bigger, more ponderous freighter squarely in the path of the approaching stones.
The freighter tried to maneuver away from the avalanche but it was too slow, too cumbersome to escape. Its captain did manage to turn it enough so that its bulky cargo of asteroidal ores took the brunt of the cascade.
Harbin watched, fascinated, as the blizzard of rocks struck the freighter. Most of them hit the massive cargo of ores that the ship carried in its external grippers. Harbin saw sparks, puffs of dust, as the stones struck in the complete silence of airless space.
“I wouldn’t want to be in that shooting gallery,” the executive officer muttered.
Harbin glanced away from the screen momentarily, saw that the weapons tech was tending to the comm technician, who was sitting up woozily in her chair.
