“How deep into the Belt will we hafta go?”
“We’d better bring Fuchs into this; he’s the expert.”
In a few minutes the four of them were seated around the table in the ship’s wardroom: Amanda and Fuchs on one side, Pancho and Dan on the other. A computer-generated chart of the Asteroid Belt was displayed on the bulkhead screen, a ragged sprinkling of colored dots between thin yellow circles representing the orbits of Mars and Jupiter.
“So you can see that the metallic asteroids,” Fuchs was saying, in an almost pedantic drone, “lie mostly in the outer areas of the Belt. This is a region that hasn’t been explored as well as the inner zones.”
“Which is why we haven’t picked a specific metallic rock as yet,” said Dan.
“What’re we talkin’ here?” Pancho asked. “Three A Us? Four?”
“Four astronomical units,” Amanda replied, “give or take a fraction.”
“And you want to head out there and scout around?” Pancho clearly looked incredulous.
“We have enough fuel for some maneuvering,” Dan said.
Pulling her palmcomp from her coverall pocket, Pancho said, “Some maneuvering. But at that distance, not a helluva lot.”
“I need a nice chunk of nickel-iron,” Dan said. “Doesn’t have to be big: a few hundred meters will do just fine.”
Fuchs broke into a smile. It made his heavy-featured, normally dour face light up. “I think I understand. A nickel-iron piece a few hundred meters across would contain enough iron ore to feed the world’s steel industry for a year or more.”
Dan jabbed a forefinger in his direction. “You’ve got it, Lars. That’s what I want to show them, back home.”
Amanda spoke up. “Didn’t someone bring a nickel-iron asteroid into the Earth-Moon vicinity?”
“Gunn did it,” Fuchs answered. “He even named the asteroid Pittsburgh, after the steel-producing center in the United States.”
“Yeah, and the double-damned GEC tossed Gunn off the rock and damned near ruined him,” Dan recalled sourly.
“You simply can’t have people bringing potentially dangerous objects into the Earth-Moon region,” Amanda said. “Suppose this Pittsburgh thing somehow was perturbed into an orbit that would impact Earth? It could have been devastating.”
Dan scowled at her. “It’s been more than four centuries since Newton figured out the laws of motion and gravity. We can calculate orbits with some precision. Pittsburgh wasn’t going to endanger anything. It was just the double-damned GEC’s way of maintaining control.”
Pancho looked up from her palmcomp. “We’ve got fuel enough to maneuver for three days, out at the four AU range.”
“Good enough,” Dan said. “We’ll be scanning all the way out there. Maybe we’ll get lucky and find a nickel-iron baby right away.”
Fuchs shook his head gloomily. “There is vast emptiness out there.” Pointing to the wallscreen display, he went on, “We think of the Belt as crowded with asteroids, but really they are nothing but infinitesimal bits of matter floating in an enormous sea of emptiness. If that chart was drawn to true scale, the asteroids would be too small to see, except in a microscope.”
“A few needles in a tremendous haystack,” Amanda added.
Dan shrugged carelessly. “That’s why we have radar and telescopes and all the other sensors.”
Pancho brought the conversation back to practicality. “Okay, so we have to go huntin’ to find a metallic rock. What about the others you want, boss?”
“Lars has already picked them out.”
Tapping on his own palmcomp, lying on the table before him, Fuchs highlighted two particular asteroids on the wall display. Bright red circles flashed around them. With another touch of his stylus on the palmcomp’s tiny keyboard, the trajectory of Starpower 1 appeared on the display, with the ship’s current position outlined by a flashing yellow circle.
“The closer object is 26—238, an S-type asteroid.”
“Stony,” Amanda said.
“Yes,” Fuchs agreed, smiling at her. “Stony asteroids are rich in silicates and light metals such as magnesium, calcium and aluminum.”
Dan stared at the display. The dot showing Starpower 1’s position was noticeably moving. Christ, we’re going like a bat out of hell. He had known the facts and figures of the fusion-driven ship’s performance, but now, seeing the reality of it on the chart, it began to hit him viscerally.
