"Shouldn't have any trouble, Carr. Believe me, to a people who have progressed to the point of sending mental messages over five hundred miles of space, it'll be a cinch, understanding our simple mental processes. Bet they'll read our every thought." "That's right. But the language. Proper names and all that. Can't get those over with thought waves." "No, but I'll bet they'll have some way of solving that too. You wait and see." Carr lighted a cigar and inhaled deeply as he gazed from one of the ports. He'd never felt better in his life. Always had liked Martian tobacco, too. Wondered what they'd do when the supply ran out. One thing they couldn't produce synthetically. The disc of the satellite loomed near and it shone with a warmly inviting light. Almost red, like the color of Mars, it was. Sort of golden, rather. Anyway, he wondered what awaited them there. This was a great life, this roaming in space, unhampered by laws or conventions. The _Nomad_ was well named. "Wonder what they'll think of our yarn," he said. "And me. I wonder, too, what that ungodly thing was back there. The thing that is now the grave of some of their people. And what the golden sphere was doing so far from home. It's a mystery." * * * * * They had gone over the same ground a hundred times and had not reached a satisfactory conclusion. But perhaps they'd learn more in the city of golden domes. "Another thing," said Carr, "that's puzzled me. Why is it that Europa has not been discovered before this; that it's inhabited, I mean?" "Rocket ships couldn't carry enough fuel. Besides, our astronomers've always told us that the outer planets were too cold; too far from the sun." "That is something to think about. Maybe we'll not be able to stand the low temperature; thin atmosphere; low surface gravity." "We've our insulated suits and the oxygen helmets for the first two objections. The G-rays'll hold us down in any gravity. But we'll see mighty soon. We're here." They had entered the atmosphere as they talked and the _Nomad_ was approaching the surface in a long glide with repulsion full on. It was daytime on the side they neared. Pale daylight, but revealing. The great ball that was Jupiter hung low on the horizon, its misty outline faintly visible against the deep green of the sky. * * * * *
