Moonrise

When they did find a molecule that nested properly in their receptors, they clamped onto it and tore it apart into its individual atoms: carbon, hydrogen, nitrogen, oxygen and the rarer metals and minerals. Then other nanomachines seized the freed atoms and combined them into new molecules, new nutrients for the cells that were damaged and dying.

Deep into the cells they penetrated, into the nucleus where the huge double spiral DNA molecules worked as templates for building vital proteins. Here was where the most crucial damage had been done. The links between the two intertwining spirals, the base pairs that were the genes themselves, had been heavily damaged by the ionizing radiation. Where the nanomachines saw a break in this vital linkage, where base pairs had been broken or mismatched, the nanomachines rebuilt the bases and linked them correctly. Like vastly complex three-dimensional jigsaw puzzles, the DNA molecules were put together properly by the busily hurrying nanomachines, much as Doug’s own natural enzymes were valiantly trying to do. Together, the polymerases and the nanomachines worked frantically to repair the massive DNA molecules.

They worked with blinding speed, although time meant nothing to them. In this nanometer universe a thousandth of a second stretched like years and decades. In microseconds they repaired damaged cells and then flowed onward, seeking, testing, destroying damaged areas, rebuilding molecules for the growth of healthy new cells. DNA repair was more intricate, more demanding. It took whole tenths of seconds to repair a damaged DNA molecule. Millions of cells and DNA molecules were repaired each minute. But there were so many billions more to reach.

Killifer was not accustomed to being a hero. He was surprised to see that Ji

“You did damned fine out there,” Anson said, leaning back in her chair, gri

Unshaven, grimy, Killifer relished the glow of the rocket juice that laced his coffee. And the glow of her approval.

“Yep,” Anson said, “now I can turn over the job to Greg Masterson and leave on schedule and get myself married.”

Shocked, Killifer blurted, “Married?”

“The Dragon Lady wanted me to stay on until the expedition got back. So now you’re back and I can head for San Antone with a clear conscience.”

I’ll be damned,” Killifer said.

Anson’s expression sobered. “Shame about Bre

“Yeah.”

“What went wrong with his hopper, do you think? Why’d it die out there?”

Shifting nervously in his chair, Killifer said, “Radiation must’ve knocked out the electrical system. Something like ithat.”

“Somebody’ll have to check it out when you go back there,” said Anson.

“Yeah. Right”

“But we’ve got the polar region, that’s what’s really important.”

“How’s the Stavenger kid?”

She shrugged. “They’re working on him.”

“Is he go

With a shake of her head, Anson replied, “Damned if I know. They’ve dragooned some high-priced talent here to try nanotherapy on him, but nobody knows if it’ll work.”

Killifer was silent for a moment ’And, uh, the astronomer…’ Don’t look too anxious, he warned himself. “What’s her name?”

“The Korean? Rhee. Bianca Rhee.”

“Yeah. How’s she doing?”

“Okay, I guess, Why’re you so interested in her?”

I’m not,” he said quickly. “Just — she flew out with Stavenger, I wanted to make sure she’s okay.”

“She’s probably on duty right now. Check the astronomy dome if you want to see her.”

“Yeah,” Killifer said. “Maybe I will. After I clean up some.”

Anson gri

“Naw,” Killifer said. Then wished he hadn’t.

It made no difference. Anson, her mind turning toward her own marriage, said, “Don’t be coy, Jack. You’re a hero now. You can have your pick of the love-starved women of Moonbase, I betcha.”

Killifer gri

She wasn’t at the astronomy dome. The place was empty. Nothing there except a half dozen display screens and a computer humming to itself.

Killifer slipped into the empty chair and used the computer to find where Rhee’s quarters were. He phoned; no answer.

Maybe I can duck in there, he thought, and find the cement cover. Then when we go back to Mt. Wasser I can stick it back onto the hopper and nobody’ll ever know what happened.

He headed for Rhee’s quarters.

Bianca Rhee was at the infirmary, staring through the observation room’s window at Doug’s inert form, still swathed in the light blue cooling blankets. The medic on duty told her that Doug wasn’t expected to come out of his hypothermic coma for days. But with oriental patience, Rhee sat as immobile as he was and watched over him.

The accordion-fold door was locked but Killifer got past it easily enough, using his plastic ID card to spring the bolt. Rhee’s one room looked as neat as a real-estate model. Everything in place. Bed, desk, bureau: standard issue, same as every other apartment in Moonbase. The only signs of individuality were a set of framed photographs on the bureau, family from the looks of mem, and a delicate small lacquered vase with an imitation flower in it.

Killifer went swiftly through the desk drawers. It wasn’t there. Then the bureau. Nothing but clothes. And a pair of toe shoes, for god’s sake, beat up as hell and just as smelly. The closet Not there either.

He stood for an agonized moment in the middle of the room, so small that he could almost touch its opposing walls by stretching out his arms. It’s got to be in here someplace, he told himself. Where? He checked under her sink. Nothing.

Where the hell is it? She can’t be carrying it around with her. Can she?

Then he saw it. So obvious that he knew she wasn’t trying to hide it. She was using it as a base, beneath the flower vase. Its gold plating complimented the deep burgundy of the vase nicely. Killifer felt his pent-up breath ease out of him. Feeling enormously relieved, he slipped the cover out from under the vase and tucked it into the back pocket of his coveralls. : Cautiously, he cracked the apartment door open. Two people were coming down the tu

“It’s been almost twelve hours,” Joa

She and Greg, the Swiss scientist and Cardenas were in the infirmary’s observation room again. A young oriental woman had been sitting there when Joa

“There is improvement’ Zimmerman said, pointing a stubby finger at the monitors above Doug’s bed. “Look at his vital signs. Heartbeat is stronger. Blood pressure is almost normal. Kidney function is returning.

“But he hasn’t moved,” Greg said, peering through the window.

“That’s to be expected,” Cardenas said softly. “He’s using all his energy internally.”

“I believe,” Zimmerman said, pulling out another long black cigar, “that it will be possible to remove the hypothermic blankets in another two hours.” He chomped on the cigar with relish. “Three, at most.”

“And then?” Joa

With a sloppy shrug, Zimmerman said, “And then, sooner or later he will wake up and ask for food. He will be very hungry. Very!”
