“But we don’t need to lift it off Earth,” Mikhail said. “Why don’t we build it on the Moon?”
Toby stared at him. “Now that really is crazy.”
“Why so? On the Moon we already manufacture glass, process metals. And we have our low gravity, remember: it’s twenty-two times easier to launch a payload into space from the Moon as from Earth. And we’re already building a mass driver! There’s no reason the Sling project couldn’t be accelerated. Its launch capacity will be huge.”
They factored an estimate of the Sling’s launch capacity into their back-of-the-envelope calculations. It was immediately clear that if they could launch the bulk of the shield’s mass from the Moon, the energy savings would indeed be prodigious.
And there was still no obvious showstopper. Siobhan had felt frightened to breathe, as if she might break the spell, and they had worked on.
But now, sitting in her flat with her mother and daughter, listening to Alvarez announce this preposterous idea to the whole world, different emotions surged in her. Suddenly restless, she walked to the window.
It was nearly Christmas, 2037. Outside, kids were playing soccer. They were wearing T-shirts. While Santa Claus still bundled up on the Christmas cards, snow and frost were nostalgic dreams of Siobhan’s childhood; in England it was more than ten years since the temperature had dipped below freezing anywhere south of a line from the Severn to the Trent. She remembered her last Christmas with her father before his death, when he had railed about having to cut his lawn on Boxing Day. The world had changed hugely in her own lifetime, shaped by forces far beyond human control. How could she be so arrogant as to suppose she could manage an even greater change, in just a few years?
“I’m afraid,” she blurted.
Perdita glanced at her, troubled.
“Of the storm?” Maria asked.
“Yes, of course. But I had to work hard to get the politicians to accept the idea of the shield.”
“And now—”
“Now Alvarez is calling my bluff, in front of the whole world. Suddenly I’ve got to deliver on my promises. And that’s what frightens me. That I might fail.”
Maria and Perdita walked over to her. Maria hugged her, and Perdita rested her head on her mother’s shoulder. “You won’t fail, Mum,” Perdita said. “Anyhow you have us, remember.”
Siobhan touched her daughter’s head.
On the softwall, the President continued to speak.
“I offer you hope, but not false hope,” Alvarez said. “Even the shield alone cannot save us. But it will turn an event that would be nonsurvivable for any of us into a disaster survivable for some. That’s why we must build it—and that’s why we must build on the chance it gives us.
“It goes without saying that this will be by far the most challenging space project ever undertaken, even dwarfing our colonization of the Moon and our first footsteps on Mars. Such a mighty project cannot be managed by one nation alone—not even America.
“So we have asked all the nations and federations of the world to come together, to pool their resources and energies, and to cooperate in this most vital of space projects. I am delighted to say that we have had a virtually unanimous response.”
“ ‘Virtually unanimous’ my arse,” Miriam Grec grumbled. Here in her Euro-needle office she sipped her whiskey and settled a little deeper into the sofa. “How can you call it ‘unanimous’ when the Chinese have refused to take part?”
Nicolaus replied, “The Chinese play a long game, Miriam. We’ve always known that. No doubt they see this problem with the sun as just another geopolitical opportunity.”
“Maybe. But God alone knows what they are up to with all those taikonauts and Long March boosters …”
“Surely they will come around, in the end.”
She studied him. Even as he spoke, Nicolaus Korombel had one eye on the softscreen bearing Alvarez’s image, the other on monitors that showed in a variety of ways the world’s response to Alvarez’s unfolding message. Miriam had never met anybody with Nicolaus’s ability to parallel-process. It was just one of the reasons she valued him so much.
Although it was an odd thing, she thought, that his very hard-nosed, almost cynically robust thinking, which made him so valuable to her, also made him very opaque. She really knew very little about what he thought and believed, deep inside. Sometimes a faint worry about that gnawed at the edge of her awareness. She must get him to open up, she thought, get to know him better. But there was never any time. And in the meantime he was just too useful.
“So how’s the reaction?”
“Markets down seventeen percent,” Nicolaus said. “As a snap reaction goes, that’s not as bad as we feared. Space and high-tech stocks are booming, needless to say.”
Miriam marveled at such a response. She supposed the impulse to get rich was natural enough—indeed, the global economy wouldn’t work without it. But she did wonder what those eager investors imagined they might achieve if their financial feeding frenzy hindered the ability of the aerospace companies and others to actually get the job done.
Still, it could be worse, she told herself. At least the President’s speech was being made. Even getting the project this far had been a close-run thing.
In the world’s grandest councils, there had been a lot of heated discussion about the wisdom of the solution Miriam had pushed. The shield project would absorb the economic energies of the participating countries for years—and for what? Even the energy the shield was bound to leak through would still add up to a devastating disaster.
And were you really going to bust your balls to save the whole world? Including the Chinese who were refusing to take part, and the Africans who, recovering from the disasters of the twentieth century, were becoming newly resurgent? Couldn’t you just save America, Europe? The military chiefs had even started to develop scenarios for what might follow the sunstorm, when Eurasia and America, if they were the only industrial powers left standing, began to move out from their fortresses to “aid” the remnants of a shattered world. It really would be a new world order, Miriam was earnestly advised, a restructuring of geopolitical power that might last a thousand years …
It had taken some deep conversations with Siobhan McGorran before Miriam had been able to wrap her own limited politician’s imagination around the magnitude of the problem. The sunstorm wasn’t another June 9; it wasn’t Krakatoa or Pompeii; it wasn’t a plague or a flood. And you just couldn’t see this as an opportunity to seek petty advantage. The extinction of humankind, indeed of all life on Earth, was possible. This really was a case of all or nothing—a message Miriam had, at last, managed to batter into the heads of the rest of the world’s decision makers.
President Alvarez spoke on, calmly.
It had to be Alvarez up there on the world’s screens, of course. It had been Miriam who had so far led the political effort behind the shield project. It was she who had firmed up a solid industrial and financial base for the project, she who had gathered together the political will in her own fractious Eurasian Union and beyond to make this unlikely project happen—and she who had used up a good deal of her own political credit in the process. But by common consent, in situations like this it had to be the President of the United States who had to give the world the bad news, and the good, as it had been for generations.
“Alvarez is doing a good job,” Miriam said. “We’re lucky we got somebody like her in the hot seat at the right time.”
Nicolaus snorted. “She’s the best actor in the White House since Reagan, that’s all.”
“Oh, she’s more than that. But she might raise false hopes. Whatever we do,” she said grimly, “people are going to die.”
“But far fewer than might otherwise,” Nicolaus said. “And whatever we do, don’t expect medals. Remember, this is engineering, not magic; no matter how well this works, people are sure to die, in great numbers. And in hindsight people will blame us. We will be called the worst mass murderers in history. That is certainly the Polish way!” He grinned with an odd sort of cheerful gloominess.
