Jupiter was not, could never be habitable. Like all the outer planets beyond the asteroid orbits, it was a frozen mass of methane and ammonia; but its four largest satellites swarmed with cities and populations now at war with the Inner Planets. He would be a war prisoner, but he had to stay alive to settle accounts with «Vorga-T:1339.»

Foyle inspected the engine room of the «Nomad.» There was Hi-Thrust fuel remaining in the tanks and one of the four tail jets was still in operative condition. Foyle found the engine room manuals and studied them. He repaired the connection between fuel tanks and the one jet chamber. The tanks were on the sunside of the wreck and warmed above freezing point.

The Hi-Thrust was still liquid, but it would not flow. In free-fall there was no gravity to draw the fuel down the pipes.

Foyle studied a space manual and learned something about theoretical gravity. If he could put the «Nomad» into a spin, centrifugal force would impart enough gravitation to the ship to draw fuel down into the combustion chamber of the jet. If he could fire the combustion chamber, the unequal thrust of the one jet would impart a spin to the «Nomad.»

But he couldn't fire the jet without first having the spin; and he couldn't get the spin without first firing the jet.

He thought his way out of the deadlock; he was inspired by «Vorga.» Foyle opened the drainage petcock in the combustion chamber of the jet and tortuously filled the chamber with fuel by hand. He had primed the pump. Now, if he ignited the fuel, it would fire long enough to impart the spin and start gravity. Then the flow from the tanks would commence and the rocketing would continue.

He tried matches.

Matches will not burn in the vacuum of space.
