Terraforming is the process of altering the surface conditions of Mars to make the planet hospitable for humans and ultimately turn the planet Earth-like. It is the largest investment of resources on Mars and can be disabled by the No Terraforming Game Rule.
Terraforming Parameters are 4 surface conditions that determine the overall terraforming progress. Once a parameter reaches 100% it is identical to Earth's.
Decreased severity of Dust Storms and Meteor Storms
Increased production from Wind Turbines and MOXIEs
Decreased production from Solar Panels
Represents the density and composition of the Martian atmosphere. The higher this parameter is, the more Earth-like are the atmospheric pressure, Oxygen levels and cloud generation.
Decreased severity of Cold Waves
Permafrost starts melting above 50%
Represents the global surface temperature of Mars. The higher this parameter is, the more favorable are the conditions for Earth-like life.
Increased production from Moisture Vaporators
Represents the quality and volume of surface water on Mars. The higher this parameter is, more and larger water bodies will appear on Mars: lakes, seas and oceans.
Increased plants spread
Represents the spreading and diversity of vegetation and bacterial life on a planetary scale. The higher this parameter is, the more Mars looks like the tundra biome back on Earth, with the ultimate goal to become a quite harsh, yet habitable second home for humanity.
