Before humanity even knew what the stars were, we dreamed of visiting Mars. The bright red light in the sky has always held a particular fascination for our species, and now we can finally call it home.

Mars was once very much like Earth, but since then the atmosphere has thinned, the water has been hidden away, and unfortunately, all life has long since disappeared. Begin by thickening the atmosphere and warming up the planet, and then you can set about reintroducing water, and eventually life.

About[]

Mars is a cold, near-vacuum planet with a tiny amount of Oxygen and some Water, although it's mostly ice. It is the planet you land on in the Tutorial and the last planet in the Terrestrial Planets. Increasing Pressure will slightly increase the Temperature a little, and thus, increase Water slightly. However, none of these effects are enough to get the corresponding stats to paradise levels, so they will have to be increased with facilities. Mars contains little bit water ice and thus, if the ice is melted it is still not enough to achieve human habitability.

Trivia[]

  • Mars was once like Earth, but as Mars' habitability ended in a bow shock. By that time, Earth's life started thriving on the oceans and plate tectonics were there (they were small little islands). With some terraforming, Mars will be habitable once more, with adequate greenhouse gases as well.


  • When the sun turns into a red giant, Mars will lose its atmosphere and even parts of the surface.
  • In reality, the pressure is so low that water can only be liquid in daytime shadows. When exposed to temperatures above 283 K, it vaporizes, and at night, all water is completely ice.
  • Mars's map is inverted. The east becomes the west and the west becomes the east (centered on Elysium, not Airy Crater). If you place a site on 27S, 174E, instead the TerraGenesis coordinates will read, 27S, 6W.
  • Mars' moons Phobos and Deimos have probably been captured by Mars' gravity about 2 to 3 billion years ago. But it's only a hypothesis.
    • Another hypothesis suggest Mars's Mars's moons are formed when a planet about ⅓ the size of Mars hit it on the north pole. The debris ring formed a large moon, and it broke apart into Phobos and Deimos. The other debris fell down to Mars, forming craters and basins on its surface.
  • Phobos is now getting closer to Mars - in about 43 million years it will be destroyed by Mars' gravity, giving it a ring. But the ring will disintegrate after a couple million years. Deimos is getting further from Mars and expected to leave Mars' SOI 400-500 million years from now.
