Mars is the fourth planet in our solar system and the first to be colonized by humans. It features a unique environment characterized by its terraformed landscape, which has been transformed from a harsh desert planet into a more habitable world.
Mars features diverse geographical features, with the most prominent being its vast canyon systems and volcanic formations. The planet's surface has been transformed from its original harsh desert environment through terraforming efforts, though much of the terrain remains arid.
The planet's varied elevations create distinct microclimates, from the frigid peaks of Olympus Mons to the relatively temperate valleys of the equatorial regions. These elevation differences have been strategically utilized in the placement of human settlements, with many colonies established in areas where the atmospheric pressure and temperature are most conducive to habitation.
Mars' surface supports a variety of Earth-origin vegetation that has adapted to the terraformed environment. Areas of natural grassland can be found across the planet's more temperate regions, while hardy shrubs and specialized plants have colonized even the more challenging terrains. These transplanted Earth species have successfully established self-sustaining ecosystems, contributing to the ongoing terraforming process through natural oxygen production and soil enrichment.
The successful integration of Earth flora represents one of the most visible achievements of Mars' terraforming efforts, with some regions displaying expansive fields of vegetation that grow without the need for artificial environmental controls.
Mars was the first planet to be reached by humans. The colonization of Mars began before the invention of CER0 technology, with dome-like habitats and the introduction of genetically engineered plants to begin the process of oxygen production.
As terraforming progressed, Earth-based corporations fought with the young Martian colony over control of the planet's resources. This conflict, known as the Martian Resource War, lasted half a decade before a compromise was reached. A treaty established joint management of Martian resources, with a portion of profits allocated to further terraforming efforts.
After the Martian Resource War and subsequent negotiations, the Mars colony was granted independence, becoming a sovereign planet-state. In the years that followed, the Martian government focused heavily on the planet’s development and economic growth. While close ties with Earth remained, Mars would become a neutral state, not fully integrating into the unified governance of the Intergalactic Alliance.
With the dawn of CER0 technology, terraforming efforts skyrocketed. Much of Mars' surface was transformed into a more habitable environment. The expansion of Martian settlements and the development of open-air cities came in tow.
