“You’ll be able to get me a seat for the landing?”

“A front seat. I can’t allow you into the Control Center itself — it’s over-full already. But I can promise the outside room, and you’ll be seeing all the same displays that I’ll be using.”

“I’m looking forward to it. I guess you wouldn’t have time to talk to me, even if I was in the Control Center with you.”

“Certainly I would. Howard, all my work will have been done before the beanstalk landing begins — finished, checked, and checked again. I would never give a go-ahead otherwise. I have to be in the Control Center, but my plan is to sit, relax, and enjoy the action.”

“I don’t believe the relax part. But the action?” Curiosity replaced concern in Anson’s voice. “What ought we expect to see? Something spectacular?”

“That’s a great question. I know what I hope you’ll see. If something goes wrong, your guess is as good as mine — but it would sure be spectacular.” Rob smiled. “The better it goes, the less fireworks we’ll have to watch. I’ll make sure there are passes for you and Senta, for the Control Center in Santiago.”

“That’s one of the things I don’t understand. Why Santiago ? Why not at the tether point down in Quito ?”

“You can’t afford to put the control where it might get wiped out if things go wrong. If the stalk snapped, or if we can’t attach the ballast correctly at the upper end, nowhere along the equator will be safe. In the worst case, we might have to sacrifice Tether Control to save worse damage. We’ll have more than enough cable to wrap it round the Earth a couple of times.”

Anson was silent for a moment. A startled look came on his face. “You’re not joking, are you? I’m beginning to realize how much a hundred thousand kilometers of cable really is. Lordie. You and Regulo have built a monster, haven’t you? It’s bigger than Ourobouros — twice around the world instead of once.”

“Regulo insists that this is just the beginning. As soon as we have easy mass transfer from Earth we can really go to work on the System. We’ll put some of Earth’s water out on Mars, or bring asteroids down to the surface, bit by bit.”

“You’d need a Martian beanstalk, too.”

“That’s easy. We could have put one there long ago if we wanted one. You don’t need anything like as much strength in a Mars beanstalk — you could build one using ordinary graphite whiskers for the load-bearing cable. Anyway, Howard, I wasn’t serious about shipping Earth water to Mars. That wouldn’t be economical. It’s cheaper and easier to fly a comet in from the Outer System.”

“Could you do that?”

“I don’t know, but I expect so. I’m playing Regulo’s game, speculating in all directions.” Rob leaned back in his seat and rubbed at his reddened eyes. “I find I do that better when I’m tired out.”

“Of course you do.” Anson saw Rob take a quick look at his watch, and realized that the beanstalk’s schedule would control everything in Merlin’s life until the fly-in and tether. “It’s only when you’re tired out that you can let your mind run free. After this job is over, Rob, you’d better plan on a long holiday. You need a re-charge.”

“We can talk about that after the beanstalk is in position and working. Twenty more days. I leave for Atlantis in just a few hours. Will you look at a couple of other things for me while I’m away? I just don’t have time to follow them myself.”

Rob’s manner was becoming increasingly restless. His schedule was calling.

Anson nodded. “Tell me what you need.”

“I’m not quite sure. More about Cancer pertinax, that’s one item. I need to know how many people suffer from it, what the treatments are, and how close we are to finding a cure. It tends to be hereditary, but I’d like you to find out if there’s an infection possibility, too.”

“That should all be easy. The information will all be in public data banks or in research programs. Hmm. Unless Morel has treatments that he hasn’t reported yet. He might have. He always preferred to wait until his techniques were perfected before he would talk about them. But I’ll see what I can find. Anything else?”

Rob hesitated. “I don’t think this will be in any data banks, but I want to know about Corrie. Senta says she’s Regulo’s daughter. Corrie says she doesn’t believe it. Is there any way of finding out for sure, through chromosome tests or genetic matching?”

“Ah.” Howard Anson rubbed at his chest thoughtfully, running a lightning search of some internal data bank. “Sure there is, in principle. It would be dead easy if the genetic data banks were open, but they’re closed so tight I don’t know if I can crack them. It’s a privacy issue. I know there won’t be anything in the public files. A couple of years ago I talked about the same thing with Senta. I had the same reaction as you when I was told that Corrie is Regulo’s daughter. There’s nothing to support it in the birth records, and no other direct evidence. I asked Senta for more details, but she has big blanks in what she can remember. It’s probably part of the same set of memories that we’ve been trying to tap through the taliza trances.” He shrugged. “I’ll dig again, but don’t hold your breath waiting for answers. Can you think of any reason why Senta wouldn’t be telling the truth?”

“No.” Rob was reaching out to cut the connection switch. “No reason at all. Put it the other way round, though. Can you think of any reason why Corrie would be lying? They can’t both be right.”

CHAPTER 15: “I do begin to have bloody thoughts”

This was the way that an eclipsing binary must look. There was the bright disk of the smaller star, a searing white, moving steadily into occultation behind the softer glow of its orange-yellow giant companion.

Except that now the smaller star was Sol. It was hard to believe that the Sun, so small and bright, was really thousands of times the size of the nearer sphere that shone to fill a fifth of the sky. Rob looked around him for some reference point that would allow him to calibrate size and distance. There was no other disk in the sky, nothing but the hard unwinking lights of the stellar background and the diffuse glow of the nebulae.

“I wondered what was keeping you,” said a familiar voice behind him. “What do you think of it?”

Rob turned at the grated words. Regulo, gaunt and awkward, was hunched by the entrance of the viewing room. In the few weeks since he and Rob last met, his condition had visibly worsened. The rough skin of his face was scored deeper with channeled gulleys, and the white hair was sparser. Only the eyes, bright and inquisitive, were undimmed and unchanged.

“When you didn’t show up at the office, I thought you must have stopped here on the way in,” went on Regulo. “So I decided to take a look for you.” He nodded at the bulk of Lutetia, glowing in the big viewing panel. “Impressive, eh?”

Rob nodded. “It looks even better from space. You lose a lot of the impact on a viewing screen. I’m still having trouble getting used to the sheer size of it. I know the Spider must be up there somewhere, but I can’t see it. Did you put in all the modifications that I sent to you?”

“Every one.” Regulo slowly came forward to stand at Rob’s side. “You’d need a telescope to see the Spider from here. We’re still about two hundred kilometers from the surface of Lutetia. I’ll move Atlantis in close before the tap begins, so we can all have a better look at what’s going on. I didn’t want to get close too soon, or we’d have troubles with the temperature of the aquasphere.”

“Lutetia’s giving out that much heat?” Rob studied the image again. “I think there’s something a little off with your camera system on Atlantis. It’s distorting the colors that come through to the screens. What’s the surface temperature of Lutetia now?”

“About three thousand, maybe as high as thirty-one hundred. We finished the spin-up and most of the inductive heating three days ago. I could have started the tap then, but I wanted you to take another look at the Spider and see if you need to do any fine tuning before we begin.”
