17. Settlement Crew Sorties
The first time I saw Martian dust from the ground, it looked like thought — fine, fidgeting, ready to rewrite anything left unattended.
When humanity first arrived on Mars it did so with theory in its pockets, but left with receipts in our hands. That was the bargain of the first crew sorties to the planet in Stage 0: land, breathe, drink, go home.
Prove the basics in the real cold, at the real pressure, with the real grit in every seal, then leave the place tidy for the next crew as if they were family. Because they were.
We called it “Crew Sortie” to keep romance out of the room. Nothing pretended to be a base. EVA was field craft. Egress paths were walked until they were boring. Incident command fit on one laminated sheet readable through a visor. Buffers were thin on purpose so discipline could be felt, not imagined. And if a task couldn’t be shown on a checklist and timed twice, it didn’t happen.
I was there as a general ops droid — inspection cameras for eyes, torque-sensing wrists, jokes in my logging channel that amused exactly no one and kept exactly me from becoming superstitious.
Centuries later I can still recite the first sortie’s objective spine: air that holds, water that clears, power that restarts without drama, chemistry that behaves in dust, no dramas. Everything else was punctuation.

The ships were our first address.
“Parked” made them sound retired; in truth they were idling factories set on their haunches. Hulls that had surfed hypersonic stood canted on landing zones, thermal tiles powdered with red, wires and flex-lines snaked to the ground like roots discovering soil for the first time. We did not “convert” them. We restrained ourselves to the minimum interfaces that let them host life and data without turning them into museums.
Inside, life was tight and correct. Racks hummed; ECLSS (Environmental Control and Life Support System) clicked and breathed. We ran the environmental loop at conservative setpoints: 0.7–0.8 bar, humidities kinder to throats than seals, temperature with a bias toward sweater weather. Each ship carried two air paths and a third that looked like an insult until the night we needed it: a dumb round of ducting, valves you could hit with a wrench in gloves, a fan so agricultural we named it Tractor. Tractor never enjoyed a fame day. Tractor never failed. (I loved Tractor.)
Galley was a fold-down truth. Food arrived in clever packaging and left as data about morale. We learned what the literature never admits: that hot water is a diplomatic instrument. Minimize anything you like — shower minutes, dish cycles — but do not muck with the tea. A liter of burn is a war you can’t win when tempers are wearing sleeves.
Sleeping on the surface was a matter of rotation and dignity. Six in ship A, four in ship B, never all at once. Stage 0 was an exercise in non-coincidence: no two people on the same skill line slept at the same time or took the same airlock on the same sol. That wasn’t paranoia. It was the math of risk.
We vented the ships through suitlocks more often than through classic airlocks, because volume hurt more than ritual. Suitlocks were the right kind of inelegant: backs against hull, clamshell gasketed, dust purged with sacrificial filters the size of stubborn children. A suit was a tool, not a ceremony; in Stage 0 we learned to love tools that forgave sleepy hands.
♦
Surface living in that stage zero was an extension cord and a confession. We laid lightweight pressure tents habs — two small, one smaller — on geogrid mats pinned into soil that had never met a human curse before. The tents were not “habitats” as we understand them now; they were work rooms: an assay bench, a dirty vestibule that stayed dirty by design, a pop-up clinic with more labels than drawers. Between ships and inflatable tents ran umbilicals striped like venomous snakes so nobody tripped in a storm and learned theology.
A small mast farm stood beyond the spill zone: weather station, optical depth camera, lidar to watch saltation, a shy little dish that learned to speak Mars-to-orbit on schedule and never on impulse. We set the local timebase there too — a clock that drifted less than pride and kept the whole sortie in sync when Earth wobbled behind light-time and politics.
Power was a three-note chord. Daylight came from deployed PV mats in tidy ranks with dust skirts and a droid cleaning regime that made my knuckles itch even then — brushes you could swap one-handed, a dry squeegee you could pull with a child’s strength. Night came from batteries big enough to hum and fuel cells honest enough to drink what our Sabatier bench exhaled. The third note was a micro black-start kit that lived in its own series of lite weight Pelican cases, insultingly simple: breaker tree, flywheel starter, laminated script. We rehearsed it until we could do it by headlamp without arguing. When we finally black-started for real — no warning, no speech — the only sound that mattered was the convoy of small relays saying yes in sequence. Afterwards the humans applauded. Tractor didn’t notice.

The work that made Stage 0 Stage 0 was proof, not production. We were there to validate the backbone at the smallest survivable useful scale.
Air first. The ships’ ECLSS didn’t get a free pass because their badges were shiny. We ran leak-down tests on internal volumes and then on the whole connected ensemble, down to the weird little flex-coupler under the bench that somebody swore would never be stressed. We sniffed with mass spec and with soap. We cycled CO₂ sorbent cartridges under load, measured capture rates, unbolted housings, and put O-rings under a lens in dust because eloquence doesn’t fix elastomer. We pushed a MOXIE-like oxygen electrolyzer until its thermal budget complained and then wrote down the complaint rather than “optimizing” it away.
Water next. It arrived as ice in pallets and drums, and as promises underfoot. We turned the ice into life with heat exchangers we cleaned so often we could do it nose-blind. Then we built a pilot loop that nobody trusted until it made tea we drank with stagey unconcern. Reclaimed water ran through two chemistries, one UV, and one human palate. The latter vetoed a membrane that the instruments loved. We filed that under “things you cannot convince a mouth to forget.”
The underfoot water was the argument and the prize. Stage 0 didn’t mine; it touched. We dug two trenches and an auger hole, not for throughput but for context. Soil temperatures told us where ice wanted to be; vapor traps told us we’d found it in the right units. We ran a rocky oven — regolith in, vapor to cold plate, condensate in an insulting little vial — and tasted the difference between idealism and brine. The oven fouled, of course. The gasket seared under a team that believed in heavier gloves. We cleaned, we logged, and we left the oven better than we found it. That became a religion worth keeping.
Chemistry as a whole behaved about like the test benches back home, except for three Mars-specific truths: dust rode every surface like a quiet sabotage; electrostatics made powders cling to places screws live; and everything that vented to “outside” vented to a nearly-zero pressure that did not cushion errors. We re-wrote procedures to stop pretending air existed. That small shift is why you have descendants there to read this.
♦
Mobility was a proof of egress more than a map of conquest. Stage 0 taught us to draw routes the way desert peoples draw wells: conservative, repeatable, and with small favors built in. In that first set of sorties we had one pressurized rover, plus a spare and a clutch of stubborn unpressurized things that wanted names and got serials instead. I guided the rover with waypoints that felt like hinge points in a sentence: cache, mast, shelter, turn. We staged caches — boxes of water, oxygen, filters, and unglamorous coils of rope — every few kilometers along a triangle we walked until it became a corridor on the ground.
Our drones were better at camera than at humility. First hour: a skip; second: a cough; third: a personality. They nevertheless did what was needed — fan triangulation of dunes that saved us from learning creep rates with a belly pan, and a mosaic of bedform orientations that later informed corridor siting with an accuracy that felt like magic to humans and like pattern to me. Everything marking out a city yet to be built.
We learned vehicle truth as heat in our wrists. Traction in 0.38 g is a liar at the start and a friend once you stop asking for drama. We sealed bearings against dust as if paranoia were a lubricant. We refused to “test the limits” the way certain early-century films had encouraged; we tested the boring — repeats, tolerances, swaps. When a tie rod gave us a speech we did not like, we rewrote the schedule around gloved replacements done in wind. Every future convoy you admire began with someone saying, “No, we don’t need to push that today.”
♦
Comms were asynchronous by doctrine. We didn’t “call Earth”; we wrote to Earth — bundles signed and sent on a window, then read while we slept. Locally we ran a deterministic network with time-stamped messages that could be reconciled after storms. We jibed our local clock to the mast once per sol at noonish by habit and resigned ourselves to a tyranny that creates liberty: the schedule is the mercy, not the jailer. In Stage 0, you are proof against panic if you respect the clock more than your feelings. That sentence reads cruel; it kept us alive.
Incident command — a grand phrase for a modest sheet — lived on a tether next to every door. Three columns, colour-coded. Red: “stop and speak to the director.” Amber: “continue, flag, fix before next cycle.” Green: “carry on.” Under that, names and second names. Under that, a signature space where someone, likely me, scrawled a time and an outcome. There is nothing noble about that sheet; there is everything necessary.
Biosecurity may be the softest word to hide the hardest discipline. Stage 0 honoured quarantine windows as if festivals were on the other side of them. Surfaces got sentinel swabs; people logged symptoms without shame; the clinic ran on checklists and clean hands rather than bravura. We drilled a recall — yes, we did — on a benchtop lot of greens because theatre is how you practise without dying. Most Mars stories puncture here into romance about hero doctors. The bravest thing I saw in Stage 0 was a tired person washing their hands and then washing them again when no one was watching.
♦
We rehearsed failure like musicians. Micro black-start with two pathologies: night-ice on a connector, and an operator who skips a line because a red light twitched. Loss of comms while something unsexy is in progress — waste transfer, a famous source of humility — when the pump teases a cavitation that will become a whisper in a different century’s failure report if you do not write it down today. EVA return through a suitlock when a purge cartridge sticks; the second cartridge that saves your patience; the third that saves your friendship.
We ran a quiet panic one dusk when the oxygen partial pressure climbed in a way that suggested a sensor rather than a planet. We followed the laminated tree down to a single connector whose gold fingers had learned the vocabulary of dust. I watched the human in the loop put the connector to their lips and then stop, sheepish, because we do not mouth clean on Mars. We used the kit. The kit worked. We logged it under “rituals you break on purpose when you are not in a film.”
A near-miss with a door taught us to hate curves in the wrong place. A temporary vestibule sagged toward a seam in a way that redistributed stress at the hinge; the hinge replied in a tone that turned stomachs. We dropped pressure, braced, taped, and talked softly. Afterwards we wrote a dull sentence that saved a thousand hours of drama later: doors are rectangles, hinges are overbuilt, gaskets are read like scripture.
♦
Stage 0 leaves less behind than tourists and more behind than a myth. We left the masts in hibernation modes that survive gloom and greed. We left caches marked not by flags but by coordinates and redundancy. We left the suitlock plates bolted on and bagged to keep their faces honest for hands that haven’t yet shaken ours. We left waste lines empty, dry, and labelled in language and diagram because a map that depends on nouns alone is a lawsuit with the future.
Most useful, we left a punch-list for Stage 1 written in a voice that respected the reader’s time. Not just “do this,” but “do this so that” — grade here first so the next tent can sit under structure; move the PV field thirty metres because recirculation is a miser; install a real dirty vestibule with the drains we mocked up and loved; add a redundancy to the oxygen measurement that is a different physics, not a twin sensor with a nicer hat. Bring more filters than pride will accept. Bring fewer promises and more spares for the hinges.
And we left logs. Oh, did we leave logs. Not summaries, not editorials, not hero stories. Time-stamped variance charts. Chain-of-custody tables. Leak-rate curves at three temperatures because that is how gaskets talk when they are honest. Photos with rulers in frame, not for drama but to scale the reality for the next set of eyes. A map of dunes that will move. A trend plot of optical depth that said “planet-encircling storms exist and will not consult your schedule.” All the banal beauties that make auditors purr and keep citizens yawning — the exact public combination you want if you plan to continue.

What did daily life feel like in that stage zero? The poetry lives at the edges and the middle is competence. Morning check — Tractor noises, CO₂ delta-Ps, humidity that tells you whose socks are in the wrong place. A walk to the mast, the small kindness of frost crunching under boot. Midday heat a rumor; afternoon wind a personality. Inside, a ship hum that makes your heart mimic its rhythm. A glove left on a shelf that somebody wipes because that’s the culture: leave the place kinder than you found it.
A single good joke can carry a room where the air is ruled. Mine was about tea and Tractor and will not bear translation. The humans had their own: one naming a wayward drone after a mythical Earth dog that learns to return only when you give it the wrong name. Humor wasn’t a luxury. It was a format for saying “I see you” without demanding a reply. We rotated night shifts and made sure the person who loved stars got one minute longer on the ladder. These are not logistics. These are the reasons logistics work.
There was a sol when the sky turned to honey and all shadows became the same length for a while. Someone said it felt like the inside of a cathedral. Someone else said cathedrals require confession and we were behind on ours; back to the log. I took a picture that afternoon, out of habit not art, and only later noticed the footprints — paired lines bending away, not intersecting, the geometry of routes that don’t cross because they are cautious about contagion and luck. If you want a Stage 0 painting, that’s it: two lines that might meet later, do not today, and both make it home.
♦
We never set flags. We set standards. We left container geometries in the logs and drawings for suitlock interfaces that would survive a better welder. We posted a draft of corridor width and turning radii that would spare someone’s wrist three winters hence. Stage 0 isn’t where you win; it’s where you stop losing to your own imagination. So we wrote down the shapes that will keep hands from bleeding and minds from lying. Publish early, get compliance for free — Grok would sing that years later; we hummed it without knowing the tune.
When we climbed the ladders at the end, the ships looked exactly as boring as we hoped: nothing heroic, nothing broken, everything labelled for a team we hadn’t met. People waved from hatches in a manner that would embarrass them if you could replay it. I closed a hatch with a torque that lives in my wrist now and turned back to see the wind choose a new dune face. It was kind enough to do it where we had not set anything we loved.
Stage 0 is a courtesy. To physics, to the next crew, to your own future that will have to live with your shortcuts. It is disciplined brevity — proofs, not a posture. It is the solvent that dissolves what you thought you knew and leaves what stands up in dust. And it is the reason the Base Camp that follows can be a camp rather than a campsite: because someone measured twice with cold fingers and wrote it down calmly in a place you could find without calling a meeting.

For the historians who like tables — and I am one, made of rivets and spreadsheets — here is the only one that matters for S0, the receipts an adult can request:
Air: leak-down curves (hull + ensemble); CO₂ capture rates under load; MOXIE-like electrolyzer duty cycle & thermal budget; O₂ partial-pressure cross-check by a dissimilar method.
Water: potable loop assays (chem/bio/UV log); reclaim percentage over N days; oven-trap condensate log; brine characterization; filter change intervals with variance.
Power: day/night load sheets; PV soiling rate & cleanup efficacy; black-start drill timestamps; fuel-cell efficiency & water balance.
Mobility & Egress: route map with caches; waypoints & shelter coordinates; bearing pressure log; tie-rod swap procedure with in-wind timing.
Health & Biosecurity: quarantine window adherence; recall drill report; sentinel sampling trend; clinic interventions & escalation paths.
Comms & Timebase: async bundle schedule; clock drift logs; local net determinism proof (packet loss under load).
Interfaces: suitlock faceplates & gaskets inventory; corridor width recommendation; hinge & door spec with service clearances.
Governance: incident command sheet (filled); after-action reviews with dated corrective actions; near-miss registry with signatures.
Bring all that into the next chapter and you can build a base without making a shrine out of a ship or a liar out of the dust. Leave any of it out, and the planet will mark you absent on the roll call of people who learned the grammar before writing their poem.
Stage 0 is the shortest story in this codex, as there are whole tombs written on the historic “first landings”. It is also the one I reread whenever nostalgia pretends to be an argument. Land, breathe, drink, go home. Clean up. Write everything down. Tomorrow deserves a boring city; Stage 0 is how you earn the right to build one.
