The Quantum Jump by Robert Wicks - Captain Brandon was a pioneer. He explored the far reaches of space and reported back on how things were out there. So it was pretty disquieting to find out that the "far reaches of space" knew more about what went on at home than he did.

BRANDON was looking at the Milky Way. Through his perma-glas canopy, he could see it trailing across the black velvet of space like a white bridal veil. Below his SC9B scout-ship stretched the red dust deserts of Sirius Three illuminated by the thin light of two ice moons. He looked at the Milky Way.

He looked at it as a man looks at a flickering fireplace and thinks of other things. He thought of the sun, 52 trillion miles away, a pinpoint of light lost in the dazzle of the Milky Way—the Earth a speck of dust in orbit just as this planet was to its master, Sirius.

Nine light years away. Of course, thirteen years had passed on Earth since they had left, because the trip took four years by RT—relative time. But even four years is a long time to be shut up in Astro One with five other men, especially when one of them was the imperious Colonel Towers.

"A quantum jump—that's the way to beat the Reds," the colonel had said a thousand times. His well-worn expression had nothing to do with quantum mechanics—the actual change in atomic configuration due to the application of sufficient energy. Rather, it was a slang expression referring to a major advance in inter-planetary travel due to a maximum scientific and technological effort.

"Let 'em have Mars and Venus," the colonel would say—"Let 'em have the whole damn Solar System! We'll make a quantum jump—leap-frog ahead of 'em. We'll be the first men to set foot on a planet of another solar system."
