Mom does something unexpected: She kneels, putting herself on eye-level with Amber. They're on the living room carpet, all seventies-retro brown corduroy and acid-orange Paisley wallpaper, and for once, they're alone: The domestic robots are in hiding while the humans hold court. "Listen to me, sweetie." Mom's voice is breathy, laden with an emotional undertow as strong and stifling as the eau-de-Cologne she wears to the office to cover up the scent of her client's fear. "I know that's what your father's writing to you, but it isn't true. You need the company – physical company – of children your own age. You're natural , not some kind of engineered freak, even with your skullset. Natural children like you need company or they grow up all weird. Socialization isn't just about texting your own kind, Amber, you need to know how to deal with people who're different, too. I want you to grow up happy, and that won't happen if you don't learn to get on with children your own age. You're not going to be some kind of cyborg otaku freak, Amber. But to get healthy, you've got to go to school, build up a mental immune system. Anyway, that which does not destroy us makes us stronger, right?"

It's crude moral blackmail, transparent as glass and manipulative as hell, but Amber's corpus logica flags it with a heavy emotional sprite miming the likelihood of physical discipline if she rises to the bait: Mom is agitated, nostrils slightly flared, ventilation rate up, some vasodilatation visible in her cheeks. Amber – in combination with her skullset and the metacortex of distributed agents it supports – is mature enough at eight years to model, anticipate, and avoid corporal punishment. But her stature and lack of physical maturity conspire to put her at a disadvantage when negotiating with adults who matured in a simpler age. She sighs, then puts on a pout to let Mom know she's still reluctant, but obedient. "O-kay. If you say so."

Mom stands up, eyes distant – probably telling Saturn to warm his engine and open the garage doors. "I say so, punkin. Go get your shoes on, now. I'll pick you up on my way back from work, and I've got a treat for you; we're going to check out a new church together this evening." Mom smiles, but it doesn't reach her eyes: Amber has already figured out she's going through the motions in order to give her the simulated middle-American upbringing she believes Amber desperately needs before she runs head first into the future. She doesn't like the churches any more than her daughter does, but arguing won't work. "You be a good little girl, now, all right?"

The imam is at prayer in a gyrostabilized mosque.

His mosque is not very big, and it has a congregation of one: He prays on his own every seventeen thousand two hundred and eighty seconds. He also webcasts the call to prayer, but there are no other believers in trans-Jovian space to answer the summons. Between prayers, he splits his attention between the exigencies of life support and scholarship. A student both of the Hadith and of knowledge-based systems, Sadeq collaborates in a project with other scholars who are building a revised concordance of all the known isnads, to provide a basis for exploring the body of Islamic jurisprudence from a new perspective – one they'll need sorely if the looked-for breakthroughs in communication with aliens emerge. Their goal is to answer the vexatious questions that bedevil Islam in the age of accelerated consciousness; and as their representative in orbit around Jupiter, these questions fall most heavily on Sadeq's shoulders.

Sadeq is a slightly built man, with close-cropped black hair and a perpetually tired expression: Unlike the orphanage crew he has a ship to himself. The ship started out as an Iranian knock off of a Shenzhou-B capsule, with a Chinese type 921 space-station module tacked onto its tail; but the clunky, 1960s look-alike – a glittering aluminum dragonfly mating with a Coke can – has a weirdly contoured M2P2 pod strapped to its nose. The M2P2 pod is a plasma sail, built in orbit by one of Daewoo's wake shield facilities. It dragged Sadeq and his cramped space station out to Jupiter in just four months, surfing on the solar breeze. His presence may be a triumph for the umma, but he feels acutely alone out here: When he turns his compact observatory's mirrors in the direction of the Sanger , he is struck by its size and purposeful appearance. Sanger 's superior size speaks of the efficiency of the Western financial instruments, semiautonomous investment trusts with variable business-cycle accounting protocols that make possible the development of commercial space exploration. The Prophet, peace be unto him, may have condemned usury; but it might well have given him pause to see these engines of capital formation demonstrate their power above the Great Red Spot.

After finishing his prayers, Sadeq spends a couple of precious extra minutes on his mat. He finds meditation comes hard in this environment: Kneel in silence, and you become aware of the hum of ventilation fans, the smell of old socks and sweat, the metallic taste of ozone from the Elektron oxygen generators. It is hard to approach God in this third hand spaceship, a hand-me-down from arrogant Russia to ambitious China, and finally to the religious trustees of Qom, who have better uses for it than any of the heathen states imagine. They've pushed it far, this little toy space station; but who's to say if it is God's intention for humans to live here, in orbit around this swollen alien giant of a planet?

Sadeq shakes his head; he rolls his mat up and stows it beside the solitary porthole with a quiet sigh. A stab of homesickness wrenches at him, for his childhood in hot, dusty Yazd and his many years as a student in Qom: He steadies himself by looking round, searching the station that is now as familiar to him as the fourth-floor concrete apartment his parents – a car factory worker and his wife – raised him in. The interior of the station is the size of a school bus, every surface cluttered with storage areas, instrument consoles, and layers of exposed pipes. A couple of globules of antifreeze jiggle like stranded jellyfish near a heat exchanger that has been giving him grief. Sadeq kicks off in search of the squeeze bottle he keeps for this purpose, then gathers up his roll of tools and instructs one of his agents to find him the relevant part of the maintenance log: it's time to fix the leaky joint for good.

An hour or so of serious plumbing and he will eat freeze-dried lamb stew, with a paste of lentils and boiled rice, and a bulb of strong tea to wash it down, then sit down to review his next fly-by maneuvering sequence. Perhaps, God willing, there will be no further system alerts and he'll be able to spend an hour or two on his research between evening and final prayers. Maybe the day after tomorrow there'll even be time to relax for a couple of hours, to watch one of the old movies that he finds so fascinating for their insights into alien cultures: Apollo Thirteen, perhaps. It isn't easy, being the crew aboard a long-duration space mission. It's even harder for Sadeq, up here alone with nobody to talk to, for the communications lag to earth is more than half an hour each way – and as far as he knows, he's the only believer within half a billion kilometers.

Amber dials a number in Paris and waits until someone answers the phone. She knows the strange woman on the phone's tiny screen: Mom calls her "your father's fancy bitch" with a peculiar tight smile. (The one time Amber asked what a fancy bitch was, Mom slapped her – not hard, just a warning.) "Is Daddy there?" she asks.

The strange woman looks slightly bemused. (Her hair is blonde, like Mom's, but the color clearly came out of a bleach bottle, and it's cut really short, and her skin is dark.) "Oui. Ah, yes." She smiles tentatively. "I am sorry, it is a disposable phone you are using? You want to talk to 'im?"
