2040: Mars Begins
By 2025 CE, approximately 6,500 people had summited Mount Everest—a dangerous but increasingly accessible challenge. Fewer than 1,500 individuals had wintered at Antarctica's research stations since the 1950s, enduring months of isolation in one of Earth's harshest environments. Only around 680 people had orbited Earth, while just 27 had traveled to the Moon, with only 12 by that stage having walked its surface.
These numbers reflect the extreme difficulty of venturing beyond familiar territory. Each milestone required unprecedented commitment, resources, and human courage. Mars settlement represented a challenge orders of magnitude greater — not dozens or hundreds, but tens of thousands of people permanently leaving Earth to build a new civilization 225 million kilometers away. The scale of ambition of settling Mars made going back to the Moon in the 2030s look like a day hike.
In 2040 humans first walked on Mars. It was watched ‘live’ by ~10 billion people. The Mars Codex is the brief history of the 150 years that followed those famous flags and footprints…
It tells the story of one of humanity’s great achievements.
Landing on Mars and settling Mars were two entirely different propositions.
The first astronauts arrived on a world with almost no breathable atmosphere, no accessible surface water, punishing cold, pervasive dust and an environment in which the failure of a single critical system could be fatal. Every person, every machine and every kilogram of supplies represented an extraordinary logistical achievement.
The first question was whether humans could reach Mars and survive.
The more important question was whether they could stay.
That required something far greater than rockets. It demanded reliable sources of power, food and water; shelters that could be maintained and extended; transportation networks; local manufacturing; effective institutions; and, eventually, families and communities who considered Mars their permanent home.
Over the following 150 years, humanity gradually answered those questions.
Temporary expeditions became permanent outposts. Outposts became settlements, settlements became cities, and cities developed the foundations of an increasingly independent civilization.
The transformation was not inevitable, and it was rarely glamorous. It emerged from thousands of decisions, inventions, failures and hard-won improvements made by generations of pioneers, operators, engineers, scientists, builders and their increasingly capable machine partners.
Mars Codex is the story of that transformation.
It begins in 2040, with a handful of humans standing on an almost impossibly hostile planet.
It continues through ten eras, ending in 2190 with a world that humanity has begun to call home.
Not because Mars became Earth.
But because humanity learned how to become Martian.
