"Well, by sheer accident, the spot in space where I became finite again happened to be here. On the surface of Jupiter. I was pretty much surprised, as you can guess, to learn that this is a definitely habitable planet. Good air, plenty of food and water--no handicaps but its tremendous bulk." He sobered momentarily. "None of the others who ever crashed here survived, I guess," he said. "I've found three or four spaceships, broken to bits-- "Well, anyway--I realized that the only way for me to ever get away was to find some method of counteracting the planet's terrific gravity. And it suddenly occurred to me that the answer lay in a laboratory curiosity created way back in the 20th Century. A piece of magnetized steel that floated within upright supports above a counter-magnetized plate. "I adapted this principle and gave it a few refinements of my own. The instructions I gave you created a dual-magnet hull for the _Saturn_. Inner hull positively charged, outer hull negative. Counterbalance, you see. The outside of the ship repelled the gravitational attraction of Jupiter so strongly that it could never have landed. The inner hull tempered the effect of the outer so that an easy, drifting motion was obtained. You could vary the speed of this simply by altering the amount of E.M.F. running through the coils--" "We discovered that," interrupted the Old Man. "But you still haven't told us, son, about your 'ghost.' You like to scared the almighty hell out of all of us. How--" Lance grinned shyly. "Well, I can't take credit for that, Skipper. You see, it was sheer accident. I found a deposit of some strange new substance here on Jupiter with the most peculiar properties. The stuff seems to polarize light at its source--and reorganize it into a tri-dimensional image at a distance which can be controlled by electric power. "When I discovered that my own life-skiff couldn't make the long trip to Europa or Io, I decided to project my image out into space in the hope I'd find someone. The telekaleidoscopic rays--I guess we can call 'em that till we get a better name--are naturally attracted to metals. This cut down the haphazardness of the attempt. "It was sheer chance, though, that you should be my rescuers. Though I might have known you wouldn't abandon me without a long search. I--I'm mighty grateful to you, sir." His words struck Hanson like a thunder-clap. And the Old Man groaned. "_Omigawd!_" "What's wrong, Skipper?" "I just remembered--we was supposed to be on Europa twenty-four hours ago! By this time, all the available claims will be gobbled up. When the Corporation learns about this, we're all going to be sunk!" Diane said indignantly, "Ridiculous! You've made the first landing on Jupiter, Daddy. Surely that should be enough glory for them."
