He sat straight to look at her. In the level red light, her face was palely rosy, her eyes afire. “Why, how could you have foreseen, lass?” he answered. “I’d hate to tell you how often something in space has taken me by surprise, and that was in familiar parts. You did realize what the problem was, and figured out a solution. We needn’t worry about your breaking orders. If you’d failed, you’d have been insubordinate; but you succeeded, so by definition you showed initiative.”
“Thank you.” Eagerness blazed. “And listen, I’ve had another idea—”
He lifted a palm. “Whoa! Look, in a couple of minutes we’d better hike back to Shep, you take your station again, I get a drive unit and fly across to Rover. But first will you please, please tell me what the mess was that I got myself into?”
“Buckyballs,” she said. “Or, formally, Buckminster fullerene. I didn’t think the pitful of it that you’d slid down into could be very deep or the bottom very large. Its walls would surely slope inward. It’s really just a… pothole, though surely the formation process was different, possibly it’s a small astroblem—” She giggled. “My, the academic in me is really taking over, isn’t it? Well, essentially, the material is frictionless. It will puddle in any hole, no matter how tiny, and it has just enough cohesion that a number of such puddles close together will form a film over the entire surface. But that film is only a few molecules thick, and you can’t walk on it or anything. In this slight gravity, though—and the metal poor rock is friable—I could strike the sharp end of a hammerhead in with a single blow to act as a kind of… piton, is that the word?”
“Okay. Splendid. Dorcas had better look to her standing as the most formidable woman in known space. Now tell me what the—the hell buckyballs are.”
“They’re produced in the vicinity of supernovae. Carbon atoms link together and form a faceted spherical molecule around a single metal atom. Sixty carbons around one lanthanum is common, galactically speaking, but there are other forms, too. And with the molecule closed in on itself the way it is, it acts in the aggregate like a fluid. In fact, it’s virtually a perfect lubricant, and if we didn’t have things easier to use you’d see synthetic buckyballs on sale everywhere.” A vision rose in those ruby eyes. “It’s thought they may have a basic role in the origin of life on planets—”
“Damn near did the opposite number today,” Saxtorph said. “But you saved my ass, and the rest of me as well. I don’t suppose I can ever repay you.”
She got to her knees before him and seized his hands. “You can, Robert. You can fetch me back my man.”
Ponderously, Rover closed velocities with the iron asteroid. She couldn’t quite match, because it was under boost, but thus far the acceleration was low.
Ominously aglow, the molten mass dwarfed the spacecraft that toiled meters ahead of it; yet Sun Defter, harnessed by her own forcefield, was a plowhorse dragging it bit by bit from its former path; and the dwarf sun was at work, and Secunda’s gravity was beginning to have a real effect…
Arrived a little before the ship, the boat drifted at some distance, a needle in a haystack of stars. Laurinda was still aboard. The tug had no place to receive Shep, nor had the girl the skill to cross safely by herself in a spacesuit even though relative speeds were small. The autopilot kept her accompanying the others.
In Rovers command center, Saxtorph asked the image of Dorcas, more shakily than he had expected to, “How are you? How’s everything?” She was haggard with weariness, but triumph rang: “Kam’s got our gear packed to transfer over to you, and I– I’ve worked the bugs out of the program. Compatibility with kzin hardware was a stumbling block, but—well, it’s been operating smoothly for the past several hours, and I’ve no reason to doubt it will continue doing what it’s supposed to.”
He whistled. “Hey, quite a feat, lady! I really didn’t think it would be possible, at least in the time available, when I put you up to trying it. What’re you going to do next—square the circle, invent the perpetual motion machine, reform the tax laws, or what?”
Her voice grew steely. “I was motivated.” She regarded his face in her own screen. “How are you? Laurinda said something about your running into danger on the moon. Were you hurt?”
“Only in my pride. She can tell you all about it later. Right now we’re in a hurry.” Saxtorph became intent. “Listen, there’s been a change of plan. You and Kam both flit over to Shep. But don’t you bring her in; lay her alongside. Kam can help Laurinda aboard Rover before he moves your stuff. I’d like you to join me in a job around Shep. Simple thing and shouldn’t take but a couple hours, given the two of us working together. Though I’ll bet even money you’ll have a useful suggestion or three. Then you can line out for deep space.”
She sat a moment silent, her expression bleakened, before she said, “You’re taking the boat to Prima while the rest of us ferry Rover away.”
“You catch on quick, sweetheart.”
“To rescue Juan and Carita.”
“What else? Laurinda’s hatched a scheme I think could do the trick. Naturally, we’ll agree in advance where you’ll wait, and Shep will come join you there. If we don’t dawdle, the odds are pretty good that the kzinti won’t locate you first and force you to go hyperspatial.”
“What about them locating you?”
“Why should they expect anybody to go to Prima? They’ll buzz around Secunda like angry hornets. They may well be engaged for a while in evacuating survivors from the warship; I suspect the shuttles aren’t terribly efficient at that sort of thing. Afterward they’ll have to work out a search doctrine, when Rover can have skitted in any old direction. And sometime along about then, they should have their minds taken off us. The kzinti will notice a nice big surprise bound their way, about which it is then too late to do anything whatsoever.”
“But you—How plausible is this idea of yours?”
“Plausible enough. Look, don’t sit like that. Get cracking. I’ll explain when we meet.”
“I can take Shep. I’m as good a pilot as you are.”
Saxtorph shook his head. “Sorry, no. One of us has to be in charge of Rover, of course. I hereby pull rank and appoint you. I am the captain.”
The asteroid concealed the ship’s initial boost from any possible observers around Secunda. She applied her mightiest vector to give southward motion, out of the ecliptic plane; but the thrust had an extra component, randomly chosen, to baffle hunter analysts who would fain reduce the volume of space wherein she might reasonably be sought. That volume would grow fast, become literally astronomical, as she flew free, generator cold, batteries maintaining life support on a minimum energy level. Having thus cometed for a time, she could with fair safety apply power again to bring herself to her destination.
Saxtorph let her make ample distance before he accelerated Shep, also using the iron to conceal his start. However, he ran at top drive the whole way. It wasn’t likely that a detector would pick his little craft up. As he told Dorcas, the kzinti wouldn’t suppose a human would make for Prima. It hurt them less, losing friends, provided the friends died bravely; and few of them had mastered the art of putting oneself in the head of an enemy.
Mainly, though, Carita and Juan didn’t have much time left them. Ever circling, the planets had changed configuration since Rover arrived. The navigation system allowed for that, but could do nothing to shorten a run of 30-odd hours. Saxtorph tried to compose his soul in peace. He played a lot of solitaire after he found he was losing most of the computer games, and smoked a lot of pipes. Books and shows were poor distraction, but music helped him relax and enjoy his memories. Whatever happened next, he’d have had a better life than 90 percent of his species—99 percent if you counted in everybody who lived and died before humankind went spacefaring.
