Era 2. Codex - Autarky Awakening

11 to 20 HE Codex reflections from JB (2A*)

♦

I can date the Autarky Years to a spreadsheet.

People prefer better stories. They ask for the dust storms and spacecraft near-misses, the grainy EVA footage, the week the storm front looked like a wall of rust marching towards Ring A. Those all happened. But the hinge that turns the Basebuilder Era into Autarky Years lives in a quieter place: a ledger called the Bill of Mass (BOM) and a set of graphs that refused to be impressed by how grown-up Port Harmonia looked.

By HE 11 we had two eras behind us in embryo.

The Red Dawn Era (1-4 HE) had given us the first spine: improvised corridors, cans on stilts, survival by ingenuity and adrenaline. The Basebuilder Era (4-11 HE) had wrapped that spine in grammar: Green Zone, wedges, the first buried loop segment of Ring A, CLS rising out of the danger band. On posters and recruitment feeds we looked like a real settlement now — a few hundred people, floorspace measured in tens of thousands of square metres, corridors you could almost get lost in.

Underneath the posters, my models kept whispering the same thing: most of this still lives on Earth.

I had all the columns in one place: people, air, water, power, calories, medicine, spares, “other”. For each line we tracked not just how much we had, but how many sols we could run if the sky went quiet and nothing new arrived. Then we divided by the only clock that really mattered: the ~780-day Hohmann cycle between Earth and Mars synods.

For too many lines, the answer was “less than one window”.

Air and water looked respectable in percentage terms; our loops were closing. Power, with fission in berms and solar in its wedge, looked good on paper. But below the big numbers lived the smaller ones: filter cartridges, reagent kits, pump seals, childhood vaccines, anaesthetics, circuit boards, bearings, valves. The crates in Stores carried a second label in my mind: 0.6 windows, 0.8 windows, 0.3 windows.

The place looked like a settlement. The balance sheet still looked like a forward operating base on someone else’s credit.

We didn’t call it that yet. In the ops room we used a colder phrase: external dependency. The hydroponics tech who would later coin “living on someone else’s credit card” hadn’t had her argument in the mess yet. But the feeling was there. The hoses, pipes and cables all ran back, ultimately, to budgets, launch pads and attention spans on another world.

That was the situation at the start of the hard Autarky Years: a hardened foothold built with Basebuilders’ discipline, running on Red Dawn’s reflexes, financed — materially and psychologically — by Earth.

♦

The Autarky Years do not open with an explosion. They begin with a manifest revision.

On the wall in Mission Control we had the three clocks: local sols and months on one display, Earth time on another, and the Hohmann countdown as a small, unlovely board tracking where we sat in the current launch cycle. Whenever a window approached, we held a long, latency-ridden planning call with Earth: three control centres, assorted agencies, a cloud of consortia feeds.

The headlines for the HE 11–12 window were reassuring in that way only experienced operators find ominous. Total payload “broadly in line with previous cycles”. Schedules “under review but on track”. No impact to “critical life support or safety missions”.

Then the spreadsheets arrived.

One cargo hull scrubbed and re-manifested with less payload “for additional safety margin”. Another partly diverted to an Earth-orbit servicing mission. A third giving up a fraction of its tonnage to a satellite “of significant geopolitical interest”. A crew vehicle unchanged in mass but suspiciously heavy in media-journalists droids and light in engineering technicians.

Individually, all reasonable. In aggregate, a fifteen-percent haircut and, more importantly, the wrong mix.

We got all the food — plus a morale bump in the form of media-friendly chocolate and clothing packs. What quietly shrank or vanished were the unglamorous things at the top of our risk lists: pump spares, filter sets, medical reagents, metrology benches, control electronics for Boreal and Solaron, the tools that let us turn “good enough” into “we can sleep at night”.

My job in these moments was simple and thankless. Take the manifest. Recompute days-of-cover for every survival line. Map it to the window clock. Flag anything dropping below thresholds. Propose a plan that kept people breathing and pumps turning.

The graphs rolled over from green to amber on half a dozen items. Two ticked red.

In the resource board that followed, twelve humans and one droid sat around a composite table with a viewport onto the frost-rimmed plain. Life support, power, water, agriculture, medicine, logistics, science, construction, governance. One chair with an interface panel for me.

I briefed them line by line.

Air: safe; oxygen production on-Mars now comfortably exceeded demand, buffers healthy.

Water: workable; Boreal could keep pace if we were sensible.

Food: if anything over-supplied; we would be bored before we were hungry.

Power: robust in raw capacity, fragile in electronics — the deferred inverters and modules meant more nursing of old hardware.

Medicine: ugly; certain drugs and reagents now below one window of cover, even with rationing.

Spares: the heart of it; seals, valves, and pump kits on some life-support lines now riding the amber band.

“Recommendations?” the commander asked.

“Slow expansion,” I said. “Shift power and labour from non-critical projects to fuel, water and spares. Defer half the settlement build-out upgrades. Pause three instrument deployments. Tighten classification on certain spare kits — no cannibalisation without board approval. Rebalance agriculture toward loop efficiency, not menu variety.”

“You’re proposing to slow growth,” the Earth representative replied after the usual minutes delay, “to protect buffers you yourself model as unlikely to be breached.”

“With respect,” the Mars-based medic cut in, “your copy of the model still assumes the anaesthetic buffer that just fell off a launch manifest is actually on our shelves.”

No one shouted. The room simply got quieter, which in the Mars Command Center (MCC) is a more reliable danger signal.

In that silence was the catalyst: the realisation that we could no longer pretend a light weight Earth cargo supply cycle was just “the program having a rough year”. The spreadsheets were telling us, as clearly as any EVA close call, that a few launch slips, budget “reprofiling”, or political storms could cascade into a life-support crisis.

We could not change the sky. We could change us.

♦

The first response to the light window was embarrassingly prosaic. We multiplied boards.

Until then, only Mars Control and central Stores tracked days-of-cover in public: one consolidated table for the big survival lines. After the scare, every wedge, every satellite node, every major system got its own.

In Boreal’s control hut a panel appeared: melt capacity, buffer tanks, safe minimum reserves, all converted into “sols everyone can drink and wash” at current usage. In Solaron’s ops cabin: array output, storage, inverter health, mapped to “days we can stay lit and warm if the sky goes brown and the reactors sulk”. In the starport wedge we tracked propellant the same way: hopper flights and return vehicles expressed in windows of cover, not in tonnes.

Each morning I pushed updated numbers to those boards. Each week the Base Board sat through a litany: air, water, food, power, waste, medicine, fuel, key spares. Above one full Hohmann of cover we smiled. Between one and two-thirds we frowned. Below two-thirds we moved work, people and mass.

The language shifted almost overnight.

“We’ve got a pallet of filters en route” turned into “Line F-23 is at 0.9 windows; the next hull gets us back above one.”

“We can stretch this reagent six months” became “If Earth went dark tomorrow, we could operate anaesthetics safely into the next window plus margin.”

People started asking “how many days of chocolate?” with unnerving precision. We declined to give that a board, but some AI sub-system always did the maths.

The second move came from the power chief, not a philosopher.

Tired of elaborate proposals for clever but fragile grid upgrades, she finally snapped in a planning session:

“I don’t want one beautiful way to keep the lights on. I want two stupidly simple ways to boil water. If one gets dusted or fried, the other sits there saying ‘was that it?’”

“Two ways to boil water” escaped the room and spread like regolith dust. It became the instant test for every design and policy:

Does this life-support line have two independent paths — different chemistries, vendors, routes, or at least caches on different spokes?

Does this fuel plan rely on a single tanker?

Does this medical protocol hinge on one plant in one country staying funded and stable?

If the answer was “no”, the proposal died, no matter how elegant the slides.

At the same time we formalised what had been informal: survival lines and floors. Air, water, power, basic food, waste, medicine, key spares, fuel. Each got a minimum days-of-cover threshold expressed explicitly in Hohmann fractions. Falling below one window meant mandatory review. Below two-thirds meant expansion freezes on any project touching that line until buffers recovered.

We amended the settlement charter to say, plainly: Port Harmonia will not be run in a way that makes its people’s survival contingent on any single ship, vendor or budget.

That is what “Autarky as philosophy” means when you strip away the rhetoric: closure not as an engineering aspiration, but as a moral floor. You don’t negotiate with vacuum. You don’t outsource survival.

On my side of the consoles, I started turning a private obsession into a public instrument: ten pillars of Martian independence survivability, each scored from zero to one and plotted as an area chart — energy, life support, water and food closure, manufacturing, medicine, governance robustness, grid resilience, separation of risks, social cohesion.

The operators quickly named it the independence jellyfish plot. Early in the era it was a lopsided starfish: long on fission power and basic water, stunted in manufacturing and medicine. Every borehole lined at Boreal, every new machine tool installed, every pallet of filters replaced by a local fab widened the shape. Every manifest cut, every scare, every near-miss made it contract.

We pinned the jellyfish on the digital display wall next to the Hohmann board. Between them, the creed took visual form: never let the jellyfish shrink to feed a poster.

This was the solution in embryo: a set of rules and pictures that forced every argument — technical, political, emotional — back through the same filter. How many windows of cover? How many ways to boil water? What does this do to the jellyfish?

♦

Doctrine only matters if someone pays the bill. In Autarky, the bill came in tonnes, drills and sleepless years.

At Boreal, the ice field stopped being an experiment and became a civic obligation. The first melt plants had been sized for tens of tonnes of water per week. The second generation aimed for hundreds, then thousands. New reactors, ugly and efficient, went into berms. Arrays of heaters and electrolysis stacks turned ice and atmosphere into oxygen, hydrogen and pure water.

The metric that mattered was simple enough to write on a napkin: how many tonnes of water per sol stand between us and the next tanker? By mid-era, imported water fell into single-digit percentages. By the end, it was a rounding error — nice for comfort, irrelevant for survival.

There is a recording I keep of the night the Boreal crew first passed a thousand tonnes output rate. No speeches. Just contraband chocolate, a badly tuned guitar and a quiet line from one technician:

“That’s a thousand tonnes we don’t have to beg for.”

At the starport wedge, the transition was from fuel sink to fuel mint.

Our early ships had burned propellant strapped to their backs all the way from a blue gravity well. Every tonne of methane and oxygen landing on Mars had begun life as several tonnes in low Earth orbit. The first Sabatier pilot plant that turned Martian CO₂ and imported hydrogen into fuel was more symbol than solution.

Then Boreal’s hydrogen replaced Earth’s. We added reactors, loops, storage. The earliest Martian test surface “Hoppers” flew on propellant that had never seen Earth. Eventually a cargo hull left Leeward Flats with most of its tanks filled by Mars.

Someone painted a slogan on a tank wall where the whole city could see it from the spine:

WE PAY OUR OWN TRANSPORT NOW.

Inside Port Harmonia’s Ring A, the machine shops went through their own quiet revolution. At first their job description had been “repair what breaks”. Now it became “prevent the jellyfish from losing limbs when the manifest goes light”.

Ore processing at Ridgeway gave us metals; electrolysis cells turned regolith into rods and sheets; furnaces and machining centres turned those into pipes, brackets, fittings, pressure-rated parts. Polymers once shipped as finished seals and gaskets arrived as pellets and left as parts. Additive manufacturing stopped being a toy and became a lifeline: if a pump failed, we could print impellers and housings instead of waiting two years for a crate from Earth.

We did not become fully self-sufficient.  Not even close in this third Era on Mars. All microchips, high-end optics, certain pharmaceuticals still came wrapped in foam and hope. But by the late Autarky years, a growing fraction of core lifeline failure tickets could be closed with the phrase “resolved in-wedge” instead of “awaiting Earth spare”.

♦

Doctrine demanded exercises. So we drilled.

The first serious black-start after the light cargo supply Hohmann window was messy. We intentionally took sectors dark, islanded parts of the power grid, spun up backup generators, ran on storage. It exposed forgotten manual overrides, mislabeled breakers, ancient assumptions. People swore at me in four languages.

By HE 18, black-starts were a grim tradition. We scheduled them in awkward seasons on purpose. Once a year we pretended a spoke was gone: “Boreal’s offline”, “Starport wedge lost”, “Solar farm PV wedge dusted in.” We ran cache drills where an entire corridor sector was treated as breached and out of bounds, and we timed how fast crews could re-route supplies using only local stores.

No one loved these drills. They broke routines, paused experiments, stole sleep. They were also where theory turned into muscle memory.

The sol we managed a city-wide black-start and recovered to stable operations within twelve hours, using only local hardware and stores, there were quiet tears in the Mars Control Center. Not because we had flirted with simulated near-death, but because, for the first time, we had acted out the tail event — the bad window, the cascade — and discovered that our creed held.

This was progress in the only currency Mars respects: not posters and speeches, but a reduction in the number of ways the system can fail without killing you.

♦

Revolutions rarely arrive with banners. On Mars, the climax of the Autarky Years looks almost identical to its catalyst: another slim manifest.

Fifteen years after the first footprints on Mars, we saw familiar patterns in the planning feeds. Budget fights in capitals we would never visit. A launch mishap taking a heavy lifter off the board. Energy price spikes, political fog, the usual mix. The phrases in the manifest revisions had the same polished understatements as before: “minor adjustments”, “consolidated shipments”, “protection of core commitments”.

The difference was in the room.

I put the revised manifests up: roughly three-quarters of the tonnage we’d originally negotiated, numerous tankers ‘delayed’ a synod, many pallets of amenities and advanced diagnostics quietly excised.

Then I put the days-of-cover board alongside:

Air: 1.4 windows at projected load, with dual chemistries and spares.

Water: 1.7 windows across city and Boreal, even under conservative output.

Power: 1.1 window equivalent combining fission, PV, storage, with two independent grids capable of carrying life-support.

Food: 0.9 windows in rations plus hydro output, with headroom if menus downshifted from “interesting” to “adequate”.

Fuel: enough Mars-made propellant to cover scheduled hoppers and one crewed return without dipping into imported drums.

The numbers were still tight in places — medicine remained an annoyance, high-end electronics a chronic dependency — but there were buffers and second paths almost everywhere that mattered.

In the first light cargo Hohmann window meeting, someone had asked “Can we survive this?” In this one, no-one did. They asked:

“How much does this hurt research?”
“Which comfort projects defer?”
“How do we shave margins without touching survival floors?”

Same external shock. Different internal pulse.

Down in the mess, the news landed not as a ghost story but as a collective eye-roll.

“Another slim manifest,” someone said over a tray that was growing closer to being more Martian than Terran. “We’re losing the new gym kit and half the fancy diagnostics. Again.”

There were sighs and inventive insults for Earth politics. There was also a shrugging confidence I hadn’t logged in the first decade. When somebody quietly asked, “Are we okay?”, an engineering leader answered, “Annoyed, yes. Doomed, no.”

A few weeks into the window, a pump at Boreal failed. Years earlier that combination — pump, Boreal, unlucky season — would have put red stripes across half my dashboards. This time we shut the line down, rerouted flow, pulled a locally fabricated replacement from stores, and treated it as a drill with extra paperwork.

A dust storm sat over Solaron longer than forecast, dragging solar power output down. We shed non-critical loads. Recreational lights dimmed, some experiments went into safe mode, an art piece in a gallery cracked its humidity tolerance. The reactors hummed, the secondary grid carried as advertised, the Mars independence jellyfish barely twitched.

At the end of the window, the only emergency Base Board session convened was about disappointed Port Harmonia moral: how to explain that the new sports dome had slipped to the next cycle because the same cargo mass now bought more pump seals and filter kits.

If you are looking for a clean narrative, that meeting is the Autarky climax you want. The hardest argument in the room was about ball games, not breathable air.

We didn’t declare victory. Sensible people never do on Mars. But among the graphs there is an invisible line: the sol in 19HE a light cargo manifest arrives from Earth and the city’s main reaction is irritation, not dread.

♦

By HE 20, anyone who had lived through the last several years in a Martian world where “how many days of cover?” was as normal a question as “what’s outside the hab today?” That is how a doctrine becomes culture: when it shows up in the games people invent.

The years of light cargo resupply windows became a campfire story, told with the embellishments memory loves — shipments that were late becoming “lost”, an overnight meeting stretched into “three days without sleep”. The later light cargo resupply windows of this Era became the counterpoint: “the year we didn’t really need them as much.” In later decades parents used it to explain why the city had more melt plants than sports domes to their teenage children.

The creed leaked into habits.

Procurement officers who tried to single-source critical items found mugs in the mess printed with two logos and the caption “What could possibly go wrong?” Comfort projects that threatened survival lines died quietly once someone asked, “How many pump seals does this cost?”

It was not that people stopped wanting oceans under glass or full-gravity recreation rings. It was that the Autarky Era generation had internalised a simple truth: every spectacular thing you build on Mars sits on a plumbing diagram. If the diagram fails, so does the dream.

Rituals grew around the ugly parts.

On the anniversary of the first successful full-city black-start, operators started toasting “two ways to boil water” at the start of long shifts. At first with mugs of nutrient broth in cramped control rooms, later with better drinks in slightly nicer messes. “To two ways,” someone would say. “To boiling water twice,” came the reply.

A corridor wall in Ring A gained a line of small plaques, each engraved with the name of a delayed project and the buffer it had paid for. MRI coil deferred → fuel plant commissioned. Rec dome shelved → melt plant redundancy achieved. Nobody toured visitors there a century later; it wasn’t that kind of monument. It was for the people who made those trades and needed to remember they hadn’t simply lost.

And there was, throughout, the human cost.

Autarky looks clean in retrospect: pretty curves trending in the right direction, jellyfish filling out, days-of-cover lines climbing. Living it was mostly exhaustion. Night shifts in under-heated machine shops. Hard years in habs that stayed functional instead of beautiful because steel and concrete went to melt plants instead of rec domes. Scientists watching their instruments slip off manifests one window after another so scrubber cartridges could ride.

Some early settlers left. They gave good reasons in exit interviews: family, fatigue, affection for open skies. Beneath the lists ran the same refrain: unrelenting moral weight. Every shower, every entertainment feed, every square metre of park had to be justified in tonnes and sols.

Others stayed precisely because that weight made their lives feel meaningful.

“Don’t you ever get tired of counting everything in days-of-cover?” one operator asked another at the end of a shift, sitting on a gantry above a fuel plant.

“Of course,” came the reply. “But where else do you get to watch the graphs move because you stood in the dust and tightened a bolt?”

From my vantage point it is easy to trace inputs to outputs, policy to graph. What the curves don’t show is that kind of remark, spoken half-jokingly on an exhausted evening. That is how cultures set their defaults.

By the close of the Autarky decade, around 20HE, “never again entirely at their mercy” had stopped being a slogan on a chalked wall and become a shared design assumption. Contracts with Earth suppliers now contained clauses about second sources and supporting local manufacture. Governance charters embedded days-of-cover floors alongside electoral rules. AIs and droids like me held semi-formal veto roles on safety and standards committees: not because we were wise, but because our math refused to look away from buffer violations when humans were tempted.

Which brings us, almost, to the edge of the next era.

♦

The Red Dawn Era taught Mars how not to die in the first week. The Basebuilders Era taught it how not to trip over its own corridors and start to get the settlement organized for scaling to a city. The Autarky Era taught it a harder lesson: you cannot outsource your survival and still call yourself a settlement.

By HE 20, Port Harmonia and its spokes could, on paper and in drills, ride out multiple difficult but not impossible synods from Earth without evacuation. Not comfortably. Not with all the toys. But without abandoning the city or burying it under memorials.

That is the legacy the Pioneers inherited.

They are the ones this Codex will follow next: the people who looked at a hardened, cautious, buffer-rich system and asked, “All right. Now can we grow?” Can a culture forged around “two ways to boil water” learn to build other Martian towns, moon based starship harbors, and all the pointless but joyful things civilizations do without letting the jellyfish starve? Can a city that measured itself in windows and pump seals learn to measure itself in centuries and citizens?

Those questions sit beyond the strict boundary of the Autarky Years. But you cannot understand the arguments of the Pioneers — about terraforming, population booms, grand architecture — without remembering that someone before them spent a decade arguing over crates of filters.

The spreadsheets that defined this era are long archived now, their urgency cooled by time. The creed they encoded survives in quieter places: in how we still design wedges, in which questions Martian children are taught to ask first, and in the fact that when a launch manifest comes in light these days, no-one on Mars thinks to check whether they’ll suffocate.

They simply grumble about the delayed sports dome, raise a mug, and toast to boiling water twice.
