From JayBe: Introduction to This Volume

I was not built for cartography. My first maps were lines scratched in a maintenance slate — where a beacon failed, where a ridge ate signal, where a crew might breathe if the lights went out. On Mars, every map is an argument about life support: where air holds, where power flows, where refuge sits within a day’s reach. I learned to draw accordingly.

This codex concerns the ground beneath our cadence — the surface that sets the terms for settlement. We faced a red world that was smaller than our Earth habits, higher in relief than our courage, and heavier in consequences than our models first admitted. Dust was not just weather; altitude was not just scenery. The terrain decided pressure, pressure decided power, and power decided how far a person could safely walk between doors. We made a language for that reality and used it to choose where to stand.

You will meet in these pages the grid we laid — simple on purpose — so that a pilot, a planner, and a farmer could talk without blinking. Not bureaucracy, but a shared ruler: broad provinces, named sectors, smaller tiles, and single-click units that made route-finding and refuge planning unambiguous. Alongside it, a plain way to speak about height and hazard — the tiers that separated the forgiving lows from the brittle highs. No equations here; just enough truth to place a city, sling a cable, or know when to turn back.

From that grammar came siting instincts. We learned to favor ice within reach, two safe exits, daylight you can bank, leeward bones that don’t shear in a black-sky week, and a route to a second node that doesn’t require good luck. The spread that followed was not a race but a coverage game: a small number of well-chosen gateways, stitched by haven chains, extending refuge across sectors until a person could cross a continent without gambling their lungs.

The Martian cities arrived the way seasons do — incrementally, then suddenly. Camps became outposts; nodes learned town-ness; city hubs acquired Mayors with responsibilities they did not ask for. Pressurized urbanism emerged as a set of tests rather than specs: can you self-sustain a week of dark Earth, a month of maintenance, a year of growth without cracking your seams? The answers shaped streets, seams, courtyards, rails, and the quiet threads that make a place feel worth staying in.

I have walked lines with Olympus Mons survey crews and argued with poets about the shape of a city’s outer wedges in the MarsX Direct plan. Both conversations mattered. What follows is a perspective on the surface of Mars — how we named it, divided it, respected it — and to the city settlements that learned to belong there.

Important Note

This is the Terran [Earth] edition of this codex. It uses Earth-duration years (365 days). Dates are given in both classical ‘Common Era’ [C.E.] (e.g. 2040) and ‘Human Era’ [H.E.], which counts Earth years from the first human arrival on Mars in year zero.

The Martian [Mars] edition of this codex uses the Marian calendar for dates and times.  Mars-duration years (668–669 sols) and displays dates in the ‘Martian Era’ [M.E.], counting in Martian years (“Mears”) from the same starting event. In that edition, the year numbers are lower by a factor of roughly 1.88 compared to the H.E. years used here.
