Phoebe Station

Tickets now available: 50 to 107 light-minutes.

[Heard on live evening newscast 2197-06-01 on Ceres]

“Twelve kiloseconds ago, Orbital Materials LLC announced their intention to establish an oxyhydrogen propellant depot on Phoebe, a retrograde satellite of Saturn, within the next decade. A spokesman from Orbital said Phoebe was purchased from a private collector. We have colonization analyst Helen Graves here with us on Ceres. Helen?”

“Right here, Mindy.”

“Helen, what are your thoughts on the Orbital Materials acquisition?”

“Well Mindy, as you know, I’ve studied interplanetary colonization for decades, and the Orbital acquisition seems hopelessly long-sighted. Phoebe orbits Saturn, and there are no present plans for colonization that far out. The closest well-frequented base would be Pasiphae Station, in the Jovian system. Frankly, Mindy, they just won’t have any customers.”

“What do you think is their aim in acquiring such a risky investment, then?”

“I’m guessing they intend to bootstrap colonization efforts themselves. Phoebe is undeniably well-suited for it. The moon orbits retrograde, which makes it easier to rendezvous with from certain Hohmanns, especially with slingshot capture tethers. It also has the vast wealth in water to make the fuel itself.”

“Thanks, Helen. Again, if you’re just joining us, Orbital Materials has acquired the moon Phoebe for speculative use as a propellant depot. Construction will start after the first crews arrive; I’m told Orbital will use higher-energy transfers to cut down on the six-year Hohmann from Earth. I’m Mindy Graham, and this is Ceres Evening News.”

Fan

Can missiles wear lead aprons?

Modern battles are fought at close range—a light-second or so—since lasers are big, heavy, slow, and radiate more than half their power into their parent ships as low-quality waste heat. That’s why every conflict since the 2110s has been fought with missiles and k-slugs.

The danger with missiles is that they’re fast and independently targeted. Try shooting them down with a gun of some type and you have a problem: the missile has traveled literally miles before your bullet gets halfway down the barrel.

Particle beam weaponry was once largely considered to be useless. About the best it can do is barf up some bremsstrahlung secondary radiation. Deliciously lethal, sure, but only in a localized area, and certainly not structurally damaging. The engineer-physicists eventually realized, however, that the particle beam is well-suited to defense. And so, the fan was invented.

The fan makes use of an otherwise annoying property of particle beams. When you deflect a stream of charged particles, you’re accelerating it, but the stream still goes basically the same speed afterward (just in a different direction). That extra energy gets dumped in the form of synchrotron radiation, streaming out tangentially in a flood of hard x-rays. So you get a searing fan of radiation, spreading knifelike in a plane.

Nowadays, when the call goes out for point defense, the ship fires up its spinal-mount linear accelerator. Huge flickering electromagnets in the bow deflect the beam semi-randomly, and a decollaminated blast of bit-flipping, electronics-frying radiation cooks the missiles as they reach the terminal guidance phase.

Small wonder the Jovian Trade Union’s radiation hardening expertise is widely-sought.

Space Bums

Immigration should do something.

“Spare change, brother?”

“Get a job!”

“That’s quite impossible.”

“Eh?”

“Impossible: adj.: not possible; unable to be, exist, happen, etc.”

“A wise guy, eh?”

“Yeah. Everybody out here has an IQ over 110. ‘Cept you, ‘parently.”

“Why, I never!”

[sighs] “We’re all descended from Earth, one way or another, but the smartest all moved out to space. So us second- and third-gen folks are all the sons and daughters of the upper-bracket erudite—including a fair measure of genius. The funny thing about IQ is that 100 is always average, so the average Earther is 80-something and the average Belter is 120.”

“I take grave exception to—”

“Oh can it already. Where are you going anyway?”

[testily] “. . . Bureau of Careers. Just shipped in with my last dime.”

[sarcastically] “And may lady fortune herself light your path to employment.”

“I will too!”

“Nope. Yer too dumb. If I can’t get a job, then you sure as hell can’t get a job. And you’re in the same boat as I—without any cash, you can’t buy your way off this rock. Might as well take a seat next to me. Yer gettin’ no job, brother.”

The Great Filter

Hint hint.

The sky teems with life. Most isn’t sapient. By the time colonization of the galaxy concluded in CE 27000, the bakers dozen of known sapient species known in the days of the proto-empire had expanded to well over a thousand, with non-sapient species numbering in the trillions.

Humans were startled to find that that not one of those thousand-odd sapient species had colonized even a single other planet. Even, for example, a one in their home solar system, mere light-minutes away. Worse, while a few had primitive space stations in low orbit, the majority hadn’t even that.

This level of space inferiority was all the more surprising for the cultural and technological marvels the surfaces of the home planets themselves boasted: undreamed-of advancements in medical and physical and mathematical sciences! So it obviously wasn’t a question of intelligence (which was, besides, approximately equal to that of humans). Therefore: “Why?”, was the question the explorers asked their (usually congenial) alien hosts.

There was no ready answer, but gradually sociologists cobbled together a theory: laziness.

As anthropocentric as it might sound, the theory made a good deal of sense. Getting off your home planet is technologically difficult—a challenge made harder still when you have to inspire a population that, by definition, has never left home, to the requisite elevation of perspective. And so it was that none of the thousand-some species, save humans alone, had ever made any progress beyond those first few, symbolic rocket flights. Imagine the catastrophe if humans had been counted among them.

Annihilator Station

No, we are not compensating for something.

During the apex of the second proto-galactic empire, spanning from approx CE 14200 to CE 14500 (before it was subsumed into the current galactic empire), great monuments of engineering were fabricated in a stupendous display of that same society’s decadence.

Annihilator Station—a name chosen, amusingly, by a third grader from the Alnilim system in a contest—provides an illustrative example.


A.S. was envisioned as a defense system for an entire solar system—specifically, the Centauri system containing the Empire’s capital. (No one was quite sure who the enemy was, but this small matter demonstrates the cavalier and bold attitude which characterized the proto-empire at peak.)

In all dimensions, A.S. was enormous. The main structure itself was built around a composite laser, whose primary bore was fully 2,000 km in diameter. The focusing system alone massed as much as Ireland. Since rotating the structure (and so the main beam itself) into an arbitrary alignment could require as long as a month, the main bore could be tapped to power secondary laser batteries—more mobile, practical laser turrets whose diameters ranged from 10 m (at the extreme lower end), up to 100 km (of which there were 10) or 50 km (of which there were 471).

It was literally the case that the combined fleets (at that time) of all interstellar nations, if put side-by-side, top-to-bottom, arranged broadside, could not cover even a tenth of that enormous aperture. The device was therefore capable of obliterating, in a single shot, the sum total of all militaries that at that time existed. For that matter, it could irradiate all of a large moon’s surface simultaneously, or cause a gas giant to combust.

The power requirement was, literally, astronomical. Just to keep the lights and life support on, A.S. burnt a (combined) mass of Plutonium the size of Gibraltar every year. The thing leaked enough air out from between atoms of its 500 m-thick hull that it had to be replenished by regular shipment. Of course, it had non-negligible gravity at its surface, too, and so keeping the lenses free of any stray, diffracting atmosphere provided employment to over 10,000,000.


In the end, the threat A.S. had been built to counter never materialized, and the station was ultimately done in by an equal mixture of logistics and intrigue.

One unfortunate fact of military operation is the necessity of hierarchy—particularly, a chain of command. Therefore, for any operation of any scope, there’s always someone in charge—maybe with advisers, but ultimately still one guy.

In this case, that guy was Grand Admiral Juiykla Hvvghinchych.

The Admiral was fond of booze and women, and, being the direct administrator of the largest military operation in history, found that he could rather simply arrange them, polity be damned. One of his consorts was a woman named Symotrishia Kavan. Ms. Kavan was connected, obliquely, to a curator of the Museum of Gambling, located on the sixth planet of the Centauris. This curator was in direct correspondence with the criminal underground, which of course was sympathetic to piracy.

Piracy, post-21st century, invariably (and necessarily) involved hit-and-run tactics. Commodity pricing on local stargates and reservations booked in advance made effective pursuit by law-enforcement all but impossible—clientele personal information, of course, being thoroughly encrypted.

The looming spectre of A.S. was a threat to piracy. Just aim one of the kilometer-wide auxiliary beams across the stargate. Ain’t nothing getting around, past, or otherwise through, that.

And so it was that the curator was smuggled four antimatter weapons, each in the 80 MT yield range, and Ms. Kavan, ah . . . convinced the good Admiral to allow the personal gift of fine whiskey to pass through customs unexamined.

The devices were detonated in the structural members near the power-generation compartments. Plenty of secondary damage was caused, including a firestorm of venting atmosphere that swept a full eightieth of the station. For her part, Ms. Kavan is believed to have perished in the blast. The Admiral himself committed suicide less than an hour after the incident. The curator was to be held for conspiracy, but died while attempting to escape—his hastily departing yacht disintegrating shortly before max-Q.

Ultimately, the structural damage to A.S. was minor—after all, a few nukes going off inside a structure the size of a small continent could almost be ignored, and the power areas, which suffered a secondary nuclear conflagration, could still be rebuilt rather simply.

Unfortunately for A.S., the bombs were the sociological straw that broke the proverbial camel’s back. The workers’ union struck, and—coupled with the already extant logistical nightmare of keeping a billion people in low-G supplied with food, water, entertainment, living quarters, and pay—caused a complete and almost instant collapse of order. The workers refused, in fact, go out to meet the cargo ships that would have brought them food. By the time the prospect of famine was upon them, it was far too late. Even moving a million people per ship was not fast enough. And so, hundreds of millions perished in the steel hallways of the greatest weapon in the galaxy. The government public-relations catastrophe alone caused, indirectly, several genocides, four planetary-scale secessions, and a new religion.

Under the circumstances, A.S. was abandoned to ruin in its own orbit.

The Dark Mystery

The fast and furious.

The first hypervelocity meteor tore through the sky on December 14th, 2069. Briefly, it illuminated the entire hemisphere before detonating over central Michigan and flattening everything from Grand Rapids to Saginaw.

No one had seen it coming.

The astronomers could be forgiven. The object itself had been the size of a basketball, and had apparently been going a fraction of the speed of light so significant that the physicists’ doubt and scorn was all but caustic when speculation on the matter gridlocked Monday’s emergency IAU meeting.

The next week, the moon was hit by a much larger projectile. The word “hit” is perhaps an understatement. It was a clear evening when Central European residents saw a tremendous luminescence emerge from the near side of the moon, and the ejecta of that impaled body traveled, hour by hour, to culminate in a shower of debris, falling mostly over the Atlantic. The remnants encircled the globe, and for a full, glorious month, the Earth had a ring.

The first telescope to see any projectile coming was that of an amateur astronomer, Charlie Bent. Bent’s telescope was not powerful in the slightest. In fact, the great Keck 4 telescope had scanned that area of sky not ten hours earlier. The object simply had, during that time, approached close enough to be visible.

Scarcely an atom remained intact . . .

In the next five seconds the object was visible to the naked eye, and then five seconds later it slammed into the atmosphere and obliterated Polk County, Florida, and Bent with it.

The most prominent theory to explain this pattern of bombardment was the destruction of some distant extrasolar planet or planetoid, although none could suggest a mechanism by which the fragments could be accelerated to such terrific velocity. In fact, the most basic calculations showed that the planet would have to be impossibly large to generate enough fragments to bombard the solar system so thoroughly (for the outposts on Mars had been hit hard too, and impacts had been observed as distant as Uranus—to say nothing of the untold billions of objects that must surely be hurtling past, unseen).

Eventually, someone suggested the obvious: the whole planet must have been moving toward us in the first place. How any intelligence could have accelerated such a mass so prodigiously, no one could tell—and what had gone wrong was, of course, even more mysterious. Certainly, investigation of the fragments themselves was impossible. Scarcely an atom remained intact beyond the initial collision with atmosphere.

As it happened, both mysteries were presently, and neatly, resolved. Tracing back the trajectories, as they had done fruitlessly so many times before, astronomers finally noticed a slight distortion in the nearby pinprick image of a remote and rather uninteresting spiral galaxy—a distortion that grew, month by month into a crescent, then a ring.

The IAU conclusion was incontrovertible: supermassive black hole. Long ago, when humans still hunted mammoths with sharpened stones, a burning star fell into the clutches of a dead one, dragging its planets into the murderous gravity. But, as the star fell to its doom, one of its planets must have been at just the right spot—dragged behind, then whipped forward in orbit around the black hole, flung with the potential energy liberated by the dying sun’s final plummet. Through the Roche limit, the planet was hurled, splintering into a trillion pieces of rock, and ejected into the interstellar void, to fly for centuries to promulgate its death.

Hey Anton,

We considered your request, but unfortunately, it must be denied. While Andromeda is in high berth, we’ll need every man onboard for inspections and extra duties. Additionally, Mars STC cannot handle any more traffic since Phobos is being developed. Advise next opportunity at Jupiter rendezvous.

Nonvariable Intelligence

Improving lives doesn’t.

Among the baker’s dozen of known galactic species that crawled their way to sapience, sociopsychologists were astonished to find that every one of them had the same intelligence. The bipeds from Earth, the avian dinosaurs from that one outer rim world, the furry bear-creatures that ate methane, put any together and they score within 10 points of each other on an IQ test. This wasn’t true for any other attribute. (Im)mortality? widely varying. Genders? Different systems. Biochemistry? Carbon through Arsenic. Size, shape? Hell no.

But intelligence? Why that?

For some species, this is an extension from a lifespan of decades to millennia. This is bad.

It turns out that entry-level sapience evolves as a survival trait. Hunt/find your food, develop technologies to make that easier, maybe do some farming, and so on. After basic establishment of civilization, mortality drops by factors in the hundreds or thousands. Population booms, and you start getting plagues from the species concentrating in cities.

This is where it gets interesting. See, once you have plagues, you need doctors. And once you have doctors, you start thinking about all of the other ways to cheat death. So the plagues are beaten back by vaccinations or antibiotics, and then your civ starts concentrating on welfare and quality-of-life.

Pretty soon, your species is living at the maximum, or nearly, of their theoretical longevity. For some species, this is an extension from a lifespan of decades to millennia.

This is bad.

At best, evolution stagnates. Your weak and stupid have the same chance of reproduction as anyone else—and they’re certainly not going to die before influencing their environments. Diseases that should have killed are mere annoyances, chomping futilely against a barrier of solid medical science. Predators that once ravaged tribes now are confined in zoos or hunted to extinction.

So no one gets any smarter.

The long and short of it is, after a certain point, intelligence is no longer a tremendous advantage to survival and, subsequently, traditional selection factors are abrogated completely. That is point at which medical science develops, which itself happens only when sapients begin the process of introspection and develop sympathy—that is, shortly after the development of sapience itself.

Haven’s Scavengers

The best nuclear engineers are bachelorettes.

Beth nudges her tiny spaceship on RCS power the last 100 km to Haven, the orbiting metropolis dangling perilously by space elevator from Pasiphae, one of the outer retrograde moons of Jupiter.

Haven approach, U.F.P. Willow cleared for docking, junction 900 E. Advise no open-cycle nuclear propulsion within 100 klicks.”

“Duh,” Beth thinks. “Why do you think I changed orbits with docking thrusters? That’s the only other burner this thing has.”

“It’s not much,” she reflects as the dull clack, felt through the berthed ship, signals the dry dock closing behind her. She’s carrying a brown paper bag filled with treasure: Tellurium superconducting wire, spare plasmabrick for reactor lining, even a canister of propulsion-grade Xenon.

It’s a high-quality, if small, collection. It will fetch a good price, but it’s getting harder. There’s simply not much left unsalvaged. And sometimes you spend delta-V and months of transit time to intercept with a derelict that’s already been picked over. 4000s is pretty good ISP for a NTR, but after months chasing wrecks in interplanetary space, that’s still an awful lot of Hydrogen and Uranium-Hex to buy at a gas giant—to say nothing of food.


Ed. note: we first saw Beth here.

The First Warp Field Generator

Genius physicist, she.

Interstellar travel is one of those persistent, persnickety engineering and logistical problems that give people who think about “deadlines” and “reliability” nightmares.

700 years after Sputnik, and the problem still seemed insoluble. Oh sure, the first interstellar seedships were already centuries underway (and later efforts had already long since beaten them to their destinations). But ships these days were at best moving at 5% of light speed, and still they needed icebergs stapled on their fronts to intercept stray dust particles.

Until one day, some genius solved the unsolvable. Japanese citizen Kasumi Tsukino, living abroad in outer Mongolia, quietly announced a working warp drive she had constructed from farming equipment in her family yurt.

Until one day, some genius solved the unsolvable.

After promptly accepting an invitation from the European Astrophysical Society, an international team of experts arrived to find the Tsukino residence quite empty. Ms. Tsukino and her apparatus had, of course, been abducted the previous evening by United States Marines.

Safely back in the states, Tsukino was given a lab, a nuclear reactor, and 40 billion USD, while the outraged, excluded world collectively stomped their feet at a U.N. special hearing.

One year later, Ms. Tsukino was quietly deported to Japan. Officially, she had entered the country without a proper Visa. For what it’s worth, this much was actually true.

The real reason turned out to be that her warp field generator simply didn’t work. Like, at all. In fact, it seemed that the primary channel by which Tsukino had surmised her device was capable of superliminal transportation was the colorful sparks it emitted and spontaneous rotation it displayed when activated.

And so technology marched onward . . .
