That Worlds May Live by Nelson S. Bond

So time sped by. And outward, ever toward the fringes of Sol's empire, flashed the _Liberty_ on her all-important mission. The sun which but a few short weeks ago had been a blazing furnace threatening fiery annihilation to the space venturers had now dwindled to the apparent size of a tiny, glowing pea, half lost in the black depths behind them. A small, feebly glistening body whose heat at this great distance was scarce sufficient to make its presence felt.

And as this great luminary shrunk, its offspring grew ever larger in the _Liberty's_ vision plate. Now the fifth planet was a heaven-filling orb scant hours away. Already the cruiser had whisked through the orbit of Jupiter's nine satellites and now, on a course carefully set by Lark O'Day, Skipper Warren was preparing to drop the _Liberty_ to Jupiter's surface.
