They went out; and at ten minutes of eleven reported at the great space ship hangars north of New York, with their luggage, a conspicuous item of which was a chess board to help while away the long, long days of spacial travel. Brand then paused a little while for a final check-up on directions.

They clambered into the tiny control room and shut the hermetically sealed trap-door. Brand threw the control switch and precisely at eleven o'clock the conical shell of metal shot heavenward, gathering such speed that it was soon invisible to human eyes. He set their course toward the blazing speck that was Jupiter, four hundred million miles away; and then reported their start by radio to Commander Stone's night operator.

The investigatory expedition to the ominous red spot of the giant of the solar system was on.


CHAPTER II

The Pipe-like Men

rand began to slacken speed on the morning of the thirteenth day (morning, of course, being a technical term: there are no horizons in space for the sun to rise over). Jupiter was still an immense distance off; but it took a great while to slow the momentum of the space ship, which, in the frictionless emptiness of space, had been traveling faster and faster for nearly three hundred hours.

Behind them was the distant ball of sun, so far off that it looked no larger than a red-hot penny. Before them was the gigantic disk of Jupiter, given a white tinge by the perpetual fog blankets, its outlines softened by its thick layer of atmosphere and cloud banks. Two of its nine satellites were in sight at the moment, with a third edging over the western rim.

"Makes you think you're drunk and seeing triple, doesn't it?" commented Dex, who was staring out the thick glass panel beside Brand. "Nine moons! Almost enough for one planet!"
