Jupiter Project

I’ve got too much work to do. I can’t keep up with everything.”

“Your group is sending down more probes?” Ishi said.

Yuri nodded earnestly, glad to get the attention off himself. “We’re trying to get all the new data we can, in time to be sent back on the Argosy.”

That’s what we were all working toward: the arrival of the Argosy, the mammoth ion rocket driven by nuclear power that was our only link with Earth, outside of laser beam. The economics of interplanetary travel are inescapable. It costs a fortune to push a pound of payload from Earth to Jupiter, struggling up out of the gravitational “hole” that the sun makes.

The whole process takes seven months and the Argosy’s sister ship Rambler follows at the next economical conjunction of Earth and Jupiter, thirteen months later. That means we get a visit every thirteen months. It seems pretty seldom to us, but ISA—the International Space Administration—counts its pennies. We aren’t likely to get more.

“Doesn’t that put the Atmospheric Studies group ahead of schedule?” Jenny said.

“A little,” Yuri admitted. “The series we’re planning will just about use up all our liquid oxygen reserves.”

“That’s not very smart,” Zak said.

“Not smart to get no results, either,” Yuri said.

“What if some emergency turns up?” Jenny said. “You won’t have any high-performance chemical fuel left.”

“Wait a minute,” I said. “I don’t get it. Why—”

“Yuri’s talking about those boosters he slaps on the ion rockets that drop our probes into the Jovian atmosphere,” Zak said. “You need the boosters when those bathyscaphes start fighting the winds, down there in the clouds.”

Jenny pursed her lips. “I still wonder about the wisdom of gobbling up that liquid oxygen.”

“Who approved the LOX?” Ishi said politely.

“My father backed it and Aarons went along.” Yuri said. “Not that Aarons could’ve stopped it. My father carries a lot of weight these days.”

I was going to ask what he meant by that, but a better idea occurred to me. “Sounds foolhardy to me,” I said with deliberate mildness. “Particularly since those bathyscaphes haven’t turned up a speck of living matter after years of trying.”

Yuri’s face tightened. “Look, junior, the day Atmospheric Studies gets a package far enough into the water clouds, below the ammonia layers, that’s the day this whole game pays off. We’re the business end of the Lab. Anything we need, we get first priority.”

“My my.” I felt my temples throbbing. “I didn’t know I was dining with royalty.”

“Yuri—” Jenny began in a conciliatory tone.

“Never mind, Jenny,” I said, standing up. “I’ve got better quality guff to listen to. Ishi, you going my way?”

Ishi hesitated a moment and then nodded. “I do have to leave.”

“Let’s hoof it,” I said, and we left the rec room.

We took a drop tube from J deck downward toward A. It was hard to talk while we held onto the conveyor belt loops, so I spent the time figuring how I could’ve slipped the needle into Yuri better, really gigged him.

We got off at D deck and took a shortcut I knew—in fact. I’d helped assemble that section out of the Argosy’s leftover fuel storage drums years before. We kids get used for low-g work a lot, because we seem to have better reflexes—and what else could we do out here, anyway, without a gold-plated PhD?

“You seemed tense back there, Matt,” Ishi interrupted my thoughts. “You wanted me to leave with you. Is there something—?”

So I told him about Yuri’s squash tactics. Ishi seemed to already know half of what I said; very little gets by him on any level, however subtle. When I was through Ishi nodded and said mildly that he would deal with Yuri when the time came. I chuckled inwardly, thinking with relish about Yuri’s impending doom. Ishi would do something crafty but completely fair, absolutely above board—and I’d enjoy every delicious moment of it. Then Ishi said, “You seem more disturbed by this than I would expect, Matt. Is there something about Yuri that bothers you?”

An idea flickered across my mind and I suppressed it. “He’s an oaf, that’s all.”

“You reacted as though threatened by him.”

“He—he tries to intimidate me, lord it over me.”

“Yuri is a type, that is all. There are many of them in the world.”

“Not in this world, not in the Can,” I said fiercely. “He’s a type I can do without. I heard through the grapevine that he waited until Mr. Jablons had a heavy work schedule in the low temperature lab. Then Yuri challenged him for the chess championship.”

“Ah. So Mr. Jablons did not have free time to think over the game between sessions? Ummm.”

I was glad I’d gotten Ishi off the subject of me and onto Yuri. And Monitoring was nearby, so I mumbled a farewell and ducked down a side corridor. I thumbed through the Caltech booklet to keep busy; there were a lot of 3Ds showing crashing white surf, rugged gray mountains and orange groves. What they didn’t show was the press of people, the pollution, the gang fights in the streets. They didn’t tell you it was a dog-eat-dog world back there, a zoo with all the animals out of their cages.

I stepped into the small alcove just inside the doorway of Monitoring. There was nobody there, so I dimmed the lights and went through a side door into the Main Station Room—only nobody calls it that, naturally; it’s known locally as the Hole.

An apt name, too, because it’s utterly dark. I stood for a moment and let my eyes adjust, not daring to move. After a while I could see the dim red lamps spaced evenly between the booths. My booth was the fifth down and I moved toward it at a slow shuffle, being careful not to bump into anything.

The Hole isn’t very big—no larger than a decent-sized apartment—but it’s crammed with equipment. I could hear someone murmuring from around a corner in the aisle; that meant the required minimum of one man on duty was satisfied. But the voice was just a drone, relaying some numbers to the bridge, so there wasn’t anything urgent.

I slipped into my booth and my hands fitted automatically into the control slots. I logged in and tried a few practice commands: a view of Europa, Jupiter’s second moon, off the port bow (reddish, ridge-streaked, most of it eaten by shadow); the docking area, from two separate cameras, showing three men maneuvering a storage drum into place; a shot of free space, with an orange rim of Jupiter in one corner. I switched over to radar.

Then I got down to business. I was sitting in my own separate booth, with my view completely filled by a soft green screen. It looked very much like an old-fashioned radar screen, with one important difference: the blips of detected objects show in three dimensions, since it’s a holographic projection. I could see a jumble of stuff in the center—the Can itself and things parked near it. Then, further out. were tiny points of light that constantly shifted and changed, vectoring in an elaborate dance.

Every second the pattern changed. Jupiter is a huge, massive planet, with a swarm of junk orbiting around it. The solar system’s asteroid belt lies between Mars and Jupiter; Jove has captured a kind of asteroid belt of its own. Compare Earth: it has Luna, a few pint-sized rocks, and that’s all. Jupiter has thirty-nine moons, three larger than Luna, and enough garbage orbiting it to make a half dozen more. Most of the junk wasn’t discovered until the first expedition came out this way, and it’s been a nuisance ever since.

I punched a few buttons and, in mathematical language, asked the ballistic computer a few questions. The machine blotted out a small rectangle in my screen and printed its answers:

NO IMMINENT COLLISIONS RECORDED.

UNKNOWN OBJECT NOTED 13:45 HOURS. PRELIMINARY CALCULATION INDICATES NO DANGER.

YOU ARE SECOND WATCH OFFICER.

I relaxed. There wasn’t going to be much to do on this watch. The chunks of rock and ice that revolve around Jupiter are dangerous—they can zip through the Can in a thousandth of a second, depressurize a level and kill somebody before it’s patched. But there weren’t any of respectable size headed for us.

Still, I checked out the unknown that had appeared at 13:45 hours. Its orbit showed that it was following an
