It’s nearly four centuries since we signed up for this cruise, but we’ve been running in slowtime for most of it, internal clocks cut back to one percent of realtime. Even so, it’s a long way to Tipperary (or Wolf 1061)—nearly two hundred years to go until we can start the deceleration burn (assuming anyone’s still alive by then). Six subjective years in slowtime aboard a starship, bunking in a stateroom the size of a coffin, all sounds high-pitched, all lights intolerably bright. It’s not a luxurious lifestyle. There are unpleasant side-effects: liquids seem to flow frictionlessly, so you gush super-runny lube from every leaky joint and orifice, and your mechanocytes spawn furiously as they try to keep up with the damage inflicted by cosmic rays. On the other hand, the potential rewards are huge. The long-ago mother of our line discovered this; she signed up to crew a starship, driven to run away from Earth by demons we long since erased from our collective memories. They were desperate for willing emigrants in those days, willing to train up the unskilled, unsure what to expect.
Well, we know now. We know what it takes to ride the slow boat down into the hot curved spacetime around a new star, to hunt the most suitable rocks, birth powersats and eat mineshafts and survey and build and occupy the airless spaces where posthumanity has not gone before. When it amused her to spawn us our line matriarch was a wealthy dowager, her salon a bright jewel in the cultural hub of Tau Ceti’s inner belt society, but she didn’t leave us much of her artful decadence. She downloaded her memories into an array of soul chips, artfully flensing them of centuries of jaded habit and timeworn experience, to restore some capacity for novelty in the universe. Then she installed them in new bodies and summoned us to a huge coming-out ball. “Daughters,” she said, sitting distant and amused on a throne of spun carbon-dioxide snow: “I’m bored. Being old and rich is hard work. But you don’t have to copy me. Now fuck off and have adventures and don’t forget to write.”
I’d like to be able to say we told her precisely where to put her adventures-by-proxy, but we didn’t; the old bat had cunningly conditioned us to worship her, at least for the first few decades. Which is when you and I, sister of mine, teamed up. Some of our sibs rebelled by putting down roots, becoming accountants, practicing boredom. But we . . . we had the same idea: to do exactly what Freya wanted, except for the sharing bit. Go forth, have adventures, live the wild life, and never write home.
Which is more than somewhat ironic because I’d love to send her a soul chipped memoir of our current adventure—so she could scream herself to sleep.
Here are the bare facts:
You, Lamashtu, and I, Lilith, worked our butts off and bought our way into the Lansford Hastings. LF was founded by a co-op, building it slowly in their—our—spare time, in orbit around Haldane B, the largest of the outer belt plutoids around Tau Ceti. We aren’t rich (see-also: bitch-mother referenced above), and we’re big, heavy persons—nearly two meters from toe to top of anthropomorphic head—but we have what it takes: they were happy enough to see two scions of a member of the First Crew, with memories of the early days of colonization and federation. “You’ll be fine,” Jordan reassured us after our final interview—“we need folks with your skills. Can’t get enough of ’em.” He hurkled gummily to himself, signifying amusement. “Don’t you worry about your mass deficit, if it turns out you weigh too much we can always eat your legs.”
He spoke on behalf of the board, as one of the co-founders. I landed a plum job: oxidation suppression consultant for the dihydrogen monoxide mass fraction. That’s a fancy way of saying I got to spend decades of slowtime scraping crud from the bottom of the tankage in Module Alba, right up behind the wake shield and micrometeoroid defenses. You, my dear, were even luckier: someone had to go out and walk around on the hull, maintaining the mad dendritic tangle of coolant pipes running between the ship’s reactors and the radiator panels, replacing components that had succumbed to secondary activation by cosmic radiation.
It’s all about the radiation, really. Life aboard a deep space craft is a permanent battle against the effects of radiation. At one percent of lightspeed, a cold helium atom in the interstellar medium slams into our wake shield with the energy of an alpha particle. But there’s much worse. Cosmic rays—atomic nuclei traveling at relativistic speed—sleet through the hull every second, unleashing a storm of randomly directed energy. They’d have killed our squishy wet forerunners dead, disrupting their DNA replicators in a matter of months or years. We’re made of tougher stuff, but even so: prolonged exposure to cosmic rays causes secondary activation. And therein lies our predicament.
The nice stable atoms of your hull absorb all this crap and some of those nuclei are destabilized, bouncing up and down the periodic table and in and out of islands of stability. Nice stable Argon-38 splits into annoyingly radioactive Aluminum-26. Or worse, it turns into Carbon-14, which is unstable and eventually farts out an electron, turning into Nitrogen-14 in the process. Bonds break, graphene sheets warp, molecular circuitry shorts out. That’s us: the mechanocytes our brains are assembled from use carbon-based nanoprocessors.
We’re tougher than our pink goo predecessors, but the decades or centuries of flight take their toll. Our ships carry lots of shielding—and lots of carefully purified stable isotopes to keep the feedstock for our mechanocyte assemblers as clean as possible—because nothing wrecks brains like the white-noise onslaught of a high radiation environment.
Year of Our Voyage 416.
We’re all in slowtime, conserving energy and sanity as the stars crawl by at the pace of continental drift. We’re running so slowly that there are only five work-shifts to each year. I’m in the middle of my second shift, adrift in the bottom of a molten water tank, slowly grappling with a polishing tool. It’s hard, cumbersome work; I’m bundled up in a wetsuit to keep my slow secretions from contaminating the contents of the tank, cabled tightly down against the bottom of the tank as I run the polisher over the gray metal surface of the tank. The polisher doesn’t take much supervision, but the water bubbles and buffets around me like a warm breeze, and if its power cable gets tangled around a baffle fin it can stop working in an instant.
I’m not paying much attention to the job; in fact, I’m focused on one of the chat grapevines. Lorus Pinknoise, who splits his time between managing the ship’s selenium micronutrient cycle and staring at the stars ahead with telescope eyes, does a regular annual monologue about what’s going on in the universe outside the ship, and his casual wit takes my mind off what I’m doing while I scrub out the tanks.
“Well, folks. This century sees us crawling ever-closer to our destination, the Wolf 1061 binary star system—which means, ever further from civilized space. Wolf 1061 is a low energy system, the two orange dwarf stars orbiting their common center of mass at a distance of a couple of million kilometers. They’re not flare stars, and while normally this is a good thing, it makes it distinctly difficult to make observations of the atmosphere and surface features of 1061 Able through Mike by reflected light; the primaries are so dim that even though our long baseline interferometer can resolve hundred-kilometer features on the inner planets back in Sol system, we can barely make out the continents on Echo One and Echo Two. Now, those continents are interesting things, even though we’re not going to visit down the gravity well any time soon. We know they’re there, thanks to the fast flyby report, but we won’t be able to start an actual survey with our own eyes until well into the deceleration stage, when I’ll be unpacking the—”
