They both stared avidly at the data coming up on the screen. Jameson was unable to interpret the tables of astronomical figures. “What’s it mean?” he said.
“Five years ago 61 Cygni had its usual wobble. Now it doesn’t.”
“The superjovian’s gone, then.”
Maybury was going over the figures. “The Cygnans would have taken it a little more than eleven years ago. Its light ran ahead of them—but not by much of a margin. We would have seen the wobble until just before the Cygnans arrived—if we’d known enough to look for it.”
Jameson looked out the viewport. The cast-off moons of Jupiter were now the brightest objects in the sky. They were tumbled carelessly across the night, like scattered dice, still rather close together. He picked out the biggest of them, a smooth white ball, the apparent size of a golfball, that had captured its own marble-sized moon.
“That’s its core,” he said. “All that’s left of a planet twelve times the mass of Jupiter. It belongs to the feathery folk. Too bad there’s no way to get it back to them.”
Maybury had found something in the figures that interested her. She was making side calculations on a lightpad.
“They were astronauts,” Jameson went on. “They made me understand that with pantomime. They were out quite a distance from their world, exploring asteroids, when the Cygnans scooped them up. They’ve got space flight, the same as we do. But their race doesn’t have star travel yet. They were as excited by the Cygnan broomstick as Mike was. They want to go home.” He paused. “But they don’t have a home to go back to, do they?”
She made a brave effort to smile. “Is that what you came here to ask me?”
“Yes.”
“The third component of 61 Cygni couldn’t have been their home, you know. It’s an unkindled star. Nothing could have lived there except creatures like the Jovians.”
“I know that. But I thought their home planet might have been a satellite of the superjovian—same as the Cygnans’ was. It was big enough to have planets. Big enough, even, to have an Earth-size planet.”
“No,” she said flatly. “That would put their planet too far away from either primary to be warmed by them. It’s not at all the same situation as Cygnus X-1 and its supergiant companion. Those were two
“And 61 Cygni is a different story?”
She almost laughed. “Commander, the two stars of 61 Cygni have a period of seven hundred and twenty days! They’re
“So their world is still there?” he said.
“Yes,” she said. “It’s still there.”
“Thanks,” he said. He squeezed her shoulder and got up to go.
She stopped him at the door. “Commander Jameson…”
He turned. “Yes?”
“Dr. Ruiz … I mean … what do you think will happen to his body? They won’t just … just throw it away, will they?”
“No,” Jameson lied. “They’ll probably allow the humans to bury it in their compound. It’s a closed ecology. Relatively closed, anyway.”
“That’s good, then,” she said slowly. “He’ll be a part of them forever now, won’t he?”
“Not just them,” he said, and left.
Sue Jarowski looked round the wreckage of Jameson’s cabin, appalled. The Cygnans had torn out everything movable, including the mattress on the bunk, and messed up what was left.
“I suppose we can make it livable,” she said doubtfully. “I’ll bring my own mattress and some cushions from the lounge.” She stared sadly at the empty shelves. “They even took your omnisound and music cards.”
“We can live without music,” Jameson said. “I was getting tired of that damned collection anyway.”
She gave him a probing look. After a moment she said, “Tod, don’t feel bad about Maggie. She isn’t worth it. She tried to get me to send a coded laser message back to Earth today. I refused. I think she was going to report Mike for sharing the Cygnan broomstick with the Chinese.”
“She won’t get very far with that. Not any more. Mike’s going to be a hero when we get back. So are we all —Maggie and Gifford and Fiaccone included. We’re all going to have to smile a lot at each other for the holocasts. The facts are going to be rearranged. Klein never murdered Ruiz. He was just another heroic crewman who died trying to save the human race. I never fought Chia’s crowd. We were all in it together. They’re going to have diplomatic problems enough splitting up the Jovian moons and the new terrestrial planet.”
Later on, he showed her 61 Cygni through the port. “It’s very faint,” he said. “You can just about make it out. Actually it’s two stars.”
“Nice,” she said, nestling up to him. She yawned. “Nice to know that there are a lot of little elves out there, covered with pink feathers.”
The communicator buzzed. Jameson reached out and switched on the audio.
“Commander,” Maybury’s voice said. “Did I wake you up?”
“No,” Jameson said.
“I just wanted you to know that I accumulated enough observational data. Jupiter’s going to miss the Earth. It’s going to pass through just where Dr. Ruiz said it would.”
“That’s fine,” he said. “That’s very fine. Now go get some sleep.”
A week later they held a modest celebration in the saloon. Jupiter had crossed Earth’s orbit twice, with no more effect than a few earthquakes and typhoons, and the bollixing up of the planetary tables in the Nautical Almanac. It already had passed the orbit of Saturn without incident, and was heading out of the solar system at the rate of six thousand kilometers per second, still picking up speed. It seemed to be heading for the Great Nebula in Andromeda.
“They paid for it, you know,” Mike Berry said.
“What?” Jameson said. He’d been preoccupied watching the antics of the two humanoids. They seemed to like alcohol too. They couldn’t tolerate the sugars in beer or wine, or the congeners in whiskey, but chilled vodka seemed to do very nicely for them, if it wasn’t mucked up with vermouth or lemon peel. Right now one of them was mixing up a new batch in a cocktail shaker, while the other was breaking up the Chinese by doing a wickedly accurate imitation of Yeh’s hulking walk.
“They paid for Jupiter,” Mike said. “They took a planet the human race couldn’t use and left us an Earth-size planet—conveniently sterile—and three of the four Galilean moons. Plus they traded us their own moon for Io. I’ll bet the archeologists will go crazy.”
“We didn’t own Jupiter. The Jovians did,” Jameson said.
Mike went on, oblivious. “That’s five more planets in the solar system that the human race can colonize. And Jupiter’s radiation belt isn’t there to keep us away.”
Jameson took a sip of his martini. Mike was only saying what had been on everybody’s tongue for the last five days. As it hurtled Sunward, Jupiter had failed to hang on to its outer satellites and the two bodies the Cygnans had brought. It had managed to hang on to Io, of course, and the piece of rock known as Jupiter V.
The core of the superjovian gas giant they had ridden into the solar system was now the size of the planet Earth. It was going to be the most valuable piece of real estate in the solar system, surpassing even Mars. It could be terraformed. They could make water out of the remnants of its hydrogen and the oxides in the rocks. It was rich in iron and heavy elements. And it was heavy enough to hold on to the atmosphere that could be squeezed out of its rocks.
“And to top it all off,” Mike was saying, “Jupiter yanked them closer to the Sun before it let go. According to Maybury, it even looks like Ganymede will end up in an elliptical orbit that’ll take it inside the orbit of Mars!”
“You overlooked the biggest gift of all,” Jameson said. “They may have given us the stars.”
Mike nodded vigorously, spilling his beer. “I’ve been going over that Cygnan broomstick with Po’s boys. Do you know that it runs on water? Takes about a pint—we’ve tried it out with the ship’s stuff. Uses the hydrogen. I
