He just couldn't wait to see how far up we were, had to look out the viewpane before his brain stopped spinning.

I was satisfied just to sit on the deck and watch him.

For an instant he stared out, his face pressed to the pane, the pulse in his forehead swelling visibly.

Then, abruptly, he turned and flashed me a startled look. "Jehoshaphat, Jim! We—we can't be travelin' that fast! Callisto's just a little crawlin' red gnat in the middle o' the sky!"


CHAPTER II

Planet Shift

I stared at him uneasily. He was talking like an idiot. I knew that Jupiter itself would have to dwindle to a small disk before Callisto could become a pin point of light. When you take off from a little moon the glare of its primary magnifies its surface features. For about one hour Callisto would look like a black orchid dwindling in a blaze of light. Then it would whip away into emptiness to reappear as a glowing dot.

"Jupiter looks funny too!" Pete muttered. "Mighty funny! Like a big slice o' yellow cheese with golden bands around it, spreadin' out—"

That did it! I got up and walked to the viewpane, slapping my hands together explosively. I had to let off steam in some way. My steadiness surprised me. My eyelids felt a little heavy, but there was nothing wrong with my space legs.
