СКАЧАТЬ and rudderless fishing boat was an uncomfortably close match for the situation up here.

      Luisa had a relaxed self-confidence that made it easy for her to admit that she knew absolutely nothing about such topics as orbital mechanics. But it was more than just that; she knew how to use her own ignorance as an icebreaker in conversations. Izzy was full of people who were skewed toward the Asperger’s end of the social spectrum, and there was no better way to get them to start talking than to ask them a technical question.

      But when everyone else was busy, Luisa was not above googling her question down to Earth and latching on to a YouTube video, as she was doing now.

      Dinah, floating behind Luisa’s shoulder, watched as the animation was replaced by a live shot of Doc Dubois and a stocky, bald white man standing next to each other on the flat pan of gray-brown dirt that she now recognized as the Moses Lake spaceport. In deep background behind them was another rocket being stacked on the pad, one stage at a time, by a tangled-looking arrangement of cranes, gantries, and cables.

      Dinah vaguely recognized the one who wasn’t Doc Dubois; he was a tech pundit who popped up frequently on television and YouTube. He turned toward the camera and spoke: “This is Tavistock Prowse, coming to you from the world’s newest spaceport here in Grant County, Washington. I’m here with a man who needs no introduction, Doc Dubois, to talk about some of the recent controversial events surrounding the Arjuna Expeditions launches, many of which are originating from the improvised launch complex that you can see directly behind us. Arjuna has prepared an animation that explains what they are all about. So pop some popcorn and pull up a chair.”

      Their image was replaced by a view of Earth that zoomed back, tilted, and panned to show it in its orbit around the sun. This was helpfully traced out by a thin, curved red line. The animation panned back. The orbits of Venus, Mercury, then Mars and Jupiter came into view. “Traditionally,” Doc Dubois said, “when we talk about asteroids, we’re talking about the asteroid belt, which is out between Mars and Jupiter.”

      A ring of dust, with a few larger clumps, was now spattered into the huge gap between those two planets’ orbits. “There’s a lot of material out there that Our Heritage might one day be able to exploit, but it’s too far away to be easily reached by any spacecraft we have now.”

      So Doc Dubois, in keeping with his rep for staying in touch with the zeitgeist, had adopted the Our Heritage phrasing, a suddenly popular buzzword and hashtag meaning “whatever gets accomplished in the distant future by the descendants of the people who make it onto the Cloud Ark,” or, to put it bluntly, “the only reason to go on living for the next twenty-two months.”

      The animation began zooming back in, to the point where it showed nothing beyond Earth’s orbit. “But astronomers have known for a long time that not all of the asteroids are out beyond Mars. There are much smaller—but still significant—populations of asteroids in heliocentric orbits not that different from Earth’s.”

      A finer and sparser dust of particles was now drawn in, forming a sort of fuzzy halo around the red line that represented Earth’s orbit.

      “And that’s where Amalthea came from, is that correct, Doc?”

      “Yes, bringing a hunk of metal that big from all the way out between Mars and Jupiter would have taken forever. Because we found it in an Earth-like orbit, it was a little easier.”

      “And what do you mean by an Earth-like orbit?”

      “These rocks all revolve around the sun just like the Earth. Some are a little inside Earth’s orbit, some a little outside of it, some cross the Earth’s orbit twice every time they go around the sun. We used to worry about those.”

      “Now, not so much,” Tav put in.

      Doc paused, and apparently thought better of acknowledging the joke. “Because we were worried about them, we made an effort to find them and to know their exact trajectories—their orbital parameters.”

      Back to Doc and Tav, now walking across the pounded earth of the spaceport with a big truck in the background emblazoned with the Arjuna Expeditions logo.

      “In recent years, companies like Arjuna Expeditions have mapped a whole lot more of those asteroids in the hopes of mining them. What we’re seeing in the last few weeks is a concerted effort by Arjuna, and an alliance of other private space companies, to throw those efforts into high gear.”

      “What exactly is Sean Probst thinking, Doc?” Tav asked.

      “He’s not telling us. But the science of orbital mechanics doesn’t leave a whole lot to the imagination. In Part Two of this video, you can learn more about the dance of orbiting bodies in space, and the intricate choreography needed to make an asteroid show up in the right place at the right time.”

      Luisa’s finger hovered over the link that would play the next video, but before tapping it, she turned around to look at Dinah. “Just trying to figure out what you do for a living,” she said, in an accent that came from everywhere, but mostly from New York. “You’re with Arjuna, right?”

      “Shh!” Dinah warned her jokingly. “I’m still trying to stay friends with the Russians.”

      “What’s that about?” Luisa asked.

      She was referring to a recent series of testy meetings, and sometimes out-and-out confrontations, between the Russians—still thinking and acting as a bloc under the leadership of Fyodor Antonovich Panteleimon—and the Arjuna contingent, which actually prided itself on being “disruptive.” This was a commonplace bit of biz jargon. But try explaining to a grizzled cosmonaut why being disruptive was a good thing.

      Dinah was inclined to say something like “It’s cultural,” but she felt a little intimidated about using that sort of cocktail-party banter around someone with Luisa’s credentials.

      “Look, surprises in space are almost always bad,” Dinah said. “Traditionally, every mission is planned out to the nth degree, and there’s a contingency plan for everything. You don’t improvise. You can’t improvise, because there’s nothing to improvise with.”

      “I’m just remembering the duct tape in Apollo 13.”

      “Yeah, that was one of the rare exceptions,” Dinah said, “and people are still talking about it decades later. So, to the Russians, the idea that someone can just show up unannounced, and make a claim on our resources—”

      “What resources?” Luisa asked.

      “They’re breathing our air,” Dinah said. “Taking up space, using bandwidth, you name it. Larz hitched a ride up here on the assumption he’d stay on Izzy and work for us—instead he’s taking off with Sean. And they are taking almost all of my robots.”

      “But they’re sending more, yes?”

      “Absolutely. Look, all I’m saying is that it was a surprise. And the sooner Sean and Larz get out of here, and on their way, the less likely it is that Fyodor is going to strangle them with his bare hands.”

      “On their way to where?” Luisa asked.

      “A different orbit.”

      “Heliocentric or geocentric?” Luisa asked, deadpan, then gave Dinah a wink.

      “Geocentric СКАЧАТЬ
