Koa's voice echoed in his helmet. "All set, Lieutenant."

The crystal appeared across the sun line and moved toward him. He met it, slowed his speed, put the end of the tube into the hole, and shoved. Kemp had allowed enough clearance. The tube slid into place. Rip turned and angled off as fast as he could glide. When he was far enough away from the blast line he called, "Fire!"

Koa squeezed the dynamo handle. The machine whined, and current shot through the wire. A column of orange fire spurted from the crystal.

Rip watched the stars instead of the exhaust. He kept running as it burned soundlessly. In air, the noise would have deafened him. In airless space, there was nothing to carry the sound.

The apparent motion of the stars was definitely slowing. The spinning wouldn't cease entirely, but it would slow down enough to give them more time to work.

The tube reached Brennschluss, and Rip called orders. "Same process. Get ready to repeat."

While Koa was connecting another igniter to the wire, Rip took a tube from Dominico. "Take your space knife and saw through the tube you have left. We'll need about three-fifths of it. Keep both pieces."

Dominico pulled his knife, pressed the release, and the gas capsule shot the blade out. He got to work.

Koa called that he was ready. Rip took the wired igniter from him and thrust it into the tube Dominico had given him.

As the crystal came around again, the process was repeated. The hole was undamaged.
