The Jupiter Theft

“At its present speed, yes,” Ruiz said.

He drummed his fingers on the arm of the chair. Finally he said, “I don’t suppose we’ll really have enough data till we’ve observed it for a few more days, but why don’t you have the computer generate a projection of the path of the Cygnus source through the solar system.”

Maybury and the young man got busy over at one of the consoles. Ruiz could hear them whispering together, having some kind of dispute, but he wasn’t paying attention. He was thinking about the trip to Earth he’d probably be making some time in the next twelve hours, dreading it. He glanced up and saw the junior resident, an angry flush on his face and chest, step away from the console and stare sulkily out the observation window. Maybury was hunched over, shoulders tense, her fingers flying over the lightboard, her bare toes twiddling in unconscious rhythm. At last she straightened up and turned in her chair.

A flat disk grew in the square darkness of the holo well. It looked something like a target, with the sun and the orbits of the inner planet crowded together to make a bull’s-eye. In the computer’s stylized representation, Pluto’s orbit was a tilted hoop intersecting the orbit of Neptune, which had briefly replaced it as the outermost planet beginning in 1987.

A yellow dotted line with an arrowhead represented the probable course of the Cygnus source. It wiggled back and forth a bit as the computer changed its mind, but it always intersected the plane of the ecliptic somewhere near the edge of the bull’s-eye.

Ruiz canted the image for better perspective and zoomed in so that Jupiter’s orbit was outermost. Now he could see the positions of the inner planets—colored beads strung on those glowing tracks, and necessarily out of scale. Six months hence, Mars would just have overtaken Jupiter, and Earth would be rounding the Sun to catch up.

That X-ray holocaust from Cygnus was going to penetrate the plane of the solar system somewhere between the orbits of Jupiter and Mars. It would pass within 4 A.U.s of Earth.

Ruiz rose out of his chair very carefully, like an old man, and walked over to the observation window. He took another long look at Cygnus, knowing it was futile. If the 500-inch telescope couldn’t see anything, he certainly wasn’t going to see anything with the naked eye. The duty tech made no attempt to follow him with her piece of paper. Even the junior resident had sense enough not to say anything.

Dr. Mackie arrived a few minutes later, still wearing his pressure suit, his helmet tucked under his arm and his turkey neck sticking out of the collar ring. He saw the look on Ruiz’s face. “What’s wrong?” he said.

Ruiz was a tough old bird. He had grown up in the squalor of a refugee camp on Long Island in the years after most of Manhattan had been rendered uninhabitable by the bomb, made of stolen reactor wastes, set off by the New England Separatists in 1998. He had clawed his way to the top on his own merits, despite the twin handicaps of poverty and a provisional ident. There wasn’t much that could unnerve him.

But now his face was gray as he turned to Mackie.

“I’m putting you in charge, Horace,” he said. “I’m going down to Earth to tell them that the human race has just been sentenced to death.”

Chapter 2

Tod Jameson flung up a gauntleted hand to protect his faceplate and yelled: “Wei hsien!”

He grabbed a startled Li Chen-yung by an air hose and spun him around. There was just enough time to plant both boots against Li’s quilted blue spacesuit and give him a mighty shove; then the flat, perforated pad of the landing leg went sailing past his head like a gigantic flyswatter. Its stately slow motion was deceptive. There was enough mass behind the pad to grind him into the hull like a bug. His spine crawling, Jameson saw it crunch its way through several honeycomb layers of the Callisto lander’s skin and embed itself there, trailing springs and broken struts.

He was drifting outward in a direction opposite to the shove he’d given Li. Earth filled the sky, a colossal backdrop of sparkling blue-and-white whorls. Against it was silhouetted the unfinished framework of the Jupiter ship, just a couple of miles off, a spidery wheel with a spear through the hub.

Li’s voice crackled in his helmet. “Thanks, buddy,” he said.

“Hwan-ying,” Jameson replied. He wondered if his Chinese sounded as stilted as Li’s English.

He located Li, a starfish shape floating in emptiness, pinwheeling crazily. As he watched, Li brought the spin under control and fired a short, economical burst from his suit jets that sent him back toward the squat bulk of the landing vehicle.

Jameson aimed himself carefully and fired his own thruster. He braked expertly within reach of a strut and hooked one foot under it. Li was already there, inspecting the mangled locking mechanism of the landing foot that had almost killed them both.

“Missing bolt,” Li said, pointing a sausagelike finger. “Big spring in leg tear loose.”
