But there were very few engineers or construction specialists among them. They were mostly escarpment areologists, or miners. Basic construction was something that robots did, or so they seemed to think. It was hard to say how long they would have gone before they would have started in on the reconstruction themselves, but with Nadia there to point out what could be done, and drive them with a brief burst of withering scorn at their inactivity, they were soon under way. Nadia worked eighteen and twenty hours a day for a few days, and got a foundation wall laid, and tenting cranes into action over the rooftops; after that it was mostly a matter of supervision. Restlessly Nadia asked her companions from Lasswitz if they would join her in the planes again. They agreed, and so about a week after their arrival they took off again, with Ann and Simon joining them in Angela and Sam’s plane.

As they flew south, down the slope of Isidis toward Burroughs, a coded message clittered abruptly over their radio speakers. Nadia dug through her pack and found a bag of stuff Arkady had given her, including a bunch of files. She found the one she wanted and plugged it into the plane’s AI, and they ran the message through Arkady’s decryption program. After a few seconds the AI spoke the message in its even tones:
“UNOMA is in possession of Burroughs, and detaining everyone who comes here.”
There was silence in the two planes, winging south through the empty pink sky. Below them the plain of Isidis sloped down to the left.
Ann said, “Let’s go there anyway. We can tell them in person to stop the assaults.”
“No,” Nadia replied. “I want to be able to work. And if they lock us up. . . Besides, why do you think they’d listen to what we tell them about the assaults?”
No answer from Ann.
“Can we make it to Elysium?” Nadia asked Yeli.
“Yes.”
So they turned east, and ignored radio queries from Burroughs air traffic control. “They won’t come after us,” Yeli said with assurance. “Look, the satellite radar shows there’s a lot of planes up and around, too many to go after all of them. And it would be a waste of time anyway, because I suspect most of them are decoys. Someone’s sent up a whole lot of drones, which confuses the issue nicely as far as we’re concerned.”
“Someone really put a lot of effort into this,” Nadia muttered as she looked at the radar image. Five or six objects were glowing in the southern quadrant. “Was it you, Arkady? Did you hide that much from me?”
She thought of that radio transmitter of his, which she had just run across in her bag. “Or maybe it wasn’t hidden. Maybe I just didn’t want to see it.”

They flew to Elysium and landed next to South Fossa, the largest roofed canyon of them all. They found that the roof was still there, but only, it turned out, because the city had been depressurized before it had been punctured. So the inhabitants were trapped in any number of intact buildings, and trying to keep the farm alive. There had been an explosion at the physical plant, and several others in the town itself. So there was a lot of work to be done, but there was a good base for a quick recovery, and a more enterprising population than the group in Peridier. So Nadia threw herself into it as before, determined to fill every waking moment with work. She could not stand to be idle; she worked every moment she was awake, her old jazz tunes running through her mind— nothing appropriate, there was no jazz or blues appropriate to this— it was all completely incongruous, “On the Sunny Side of the Street,” “Pennies from Heaven,” “A Kiss to Build a Dream On”….
And in those hectic days on Elysium she began to realize just how much power the robots had. In all her years of construction she had never really tried to exert that power to the full; there simply had been no need. But now there were hundreds of jobs to be done, more than could be accomplished even with a total effort, and so she took the system right out to the bleeding edge as programmers would say, and saw just how much that effort could do, even as she tried to figure out how to do more. She had always considered teleoperation to be a basically local procedure, for instance, but it wasn’t necessarily so. Using relay satellites she could drive a bulldozer in the other hemisphere, and now, whenever she could establish a good link, she did so. She did not stop working for even a single waking second; she worked as she ate, she read reports and programs in the bathroom, and she never slept except when exhaustion knocked her out. While in this timeless state she told anyone and everyone she worked with what to do, without regard for their opinion or comfort; and in the face of her monomaniacal concentration, and the authority of her grasp of the situation, people obeyed her.
