The Rock Rats by Ben Bova. Chapter 1, 2, 3, 4

They are the bonanza, the El Dorado, the Comstock Lode, the gold and silver and iron and everything-else mines of the twenty-first century. There are hundreds of millions of billions of tons of high grade ores in the asteroids. They hold enough real wealth to make each man, woman, and child of the entire human race into a millionaire. And then some.

The first asteroid was discovered shortly after midnight on January 1, 1801, by a Sicilian monk who happened to be an astronomer. While others were celebrating the new century, Giuseppi Piazzi was naming the tiny point of light he saw in his telescope Ceres after the pagan goddess of Sicily. Perhaps an unusual attitude for a pious monk, but Piazzi was a Sicilian, after all.

By the advent of the twenty-first century, more than fifteen thousand asteroids had been discovered by earthbound astronomers: As the human race began to expand its habitat to the Moon and to explore Mars, millions more were found.

Technically, they are planetoids, little planets, chunks of rock and metal floating in the dark void of space, leftovers from the creation of the Sun and planets some four and a half billion years ago. Piazzi correctly referred to them as planetoids, but in 1802 William Herschel (who had earlier discovered the giant planet Uranus) called them asteroids, because in the telescope their pinpoints of light looked like stars rather than the disks of planets. Piazzi was correct, but Herschel was far more famous and influential. We call them asteroids to this day.

Several hundred of the asteroids are in orbits that near the Earth, but most of them by far circle around the Sun in a broad swath in deep space between the orbits of Mars and giant Jupiter. This Asteroid Belt is centered more than six hundred million kilometers from Earth, four times farther from the Sun than our homeworld.

Although this region is called the Asteroid Belt, the asteroids are not strewn so thickly that they represent a hazard to space navigation. Far from it. The so-called Belt is a region of vast emptiness, dark and lonely and very far from human civilization.

Until the invention of the Duncan fusion drive the Asteroid Belt was too far from the Earth/Moon system to be of economic value. Once fusion propulsion became practical, however, the Belt became the region where prospectors and miners could make fortunes for themselves, or die in the effort.

Many of them died. More than a few were killed.

THREE YEARS LATER

CHAPTER 1

I said it would be simple,” Lars Fuchs repeated. “I did not say it would be easy.”

George Ambrose—Big George to everyone who knew him —scratched absently at his thick red beard as he gazed thoughtfully out through the window of Starpower 1’s bridge toward the immense looming dark bulk of the asteroid Ceres. “I di’n’t come out here to get involved in daft schemes, Lars,” he said. His voice was surprisingly high and sweet for such a shaggy mastodon of a man.

For a long moment the only sound in the compartment was the eternal hum of electrical equipment. Then Fuchs pushed between the two pilots’ seats to drift toward Big George. Stopping himself with a touch of his hand against the metal overhead, he said in an urgent whisper, “We can do it. Given time and resources.”

“It’s fookin’ insane,” George muttered. But he kept staring out at the asteroid’s rock-strewn, pockmarked surface.

They made an odd pair: the big, bulky Aussie with his shaggy brick-red mane and beard, hovering weightlessly beside the dark, intense, thickset Fuchs. Three years in the Belt had changed Fuchs somewhat: he was still burly, barrel-chested, but he had let his chestnut brown hair grow almost to his collar, and the earring he wore was now a polished chip of asteroidal copper. A slim bracelet of copper circled his left wrist. Yet in their individual ways, both men looked powerful, determined, even dangerous. “Living inside Ceres is bad for our health,” Fuchs said.

George countered, “Plenty of radiation protection from the rock.”

“It’s the microgravity,” Fuchs said earnestly. “It’s not good for us, physically.”

“I like it.”

“But the bones become so brittle. Dr. Cardenas says the rate of fractures is rising steeply. You’ve seen that yourself, haven’t you?”
