From JayBe: Introduction to This Volume
I was activated under the western skirts of Olympus Mons, in the shadow of a drydock that no longer exists. My first tasks were humble: count tank levels, time valve responses, note which doors stuck in the morning chill. History began as maintenance.
This codex book is what those maintenance logs grew into.
A Brief History of Mars follows the first hundred and fifty years after humans decided that “we should stay” was not a slogan but a design constraint. It is not a technical manual, though engineers will recognise the joints. It is an attempt to answer one precise question: how did a dead world become somewhere you can raise children without needing to explain, every day, why the sky is trying to kill them?
You will not find terraforming miracles here. By the end of the period I describe, Mars is still mostly rock and thin air. What changed was not the planet so much as the fabric we wrapped around it: habitats, rings, wedges, hoppers, rails, routines, and the quiet agreements that turned risk into something you could schedule.
We began with sorties: small crews, stacked cans, a margin of safety thin enough to measure in minutes. We learned Autarky the hard way: supply windows that arrived light, years when “just in time” proved to be a joke told by people who had never waited six months for filters. We built bases that could black-start from dark, towns that could outlast bad harvests, cities that could argue about school curricula instead of air.
My bias is plain. I favour systems that survived contact with reality: checklists over slogans, dull drills over glorious failures, redundancy over elegance. When in doubt, I trust the practices that kept pressure steady and food boring. You will see that preference in which stories made it onto these pages and which stayed in the archive.
I have organised this account into ten eras. Each one ended when Mars crosses a threshold it could not easily uncross: from camp to base, from base to town, from town to city, from dependency to “we can manage, even if Earth has a bad decade.” The details differ; the pattern does not. Again and again, people met the planet on its own terms, adjusted, and wrote the adjustment down.
If you were born on Mars, much of this may feel like background noise you grew up inside. If you weren’t, consider it an audit trail for a miracle that has, by now, had the courtesy to become ordinary.

Calendar Year 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.
