Mars is the fourth planet in the Sol System, which in Spore can be found as an easter egg. It is a temperate rocky planet with mostly plain terrain, except for geological formations like Olympus Mons, Valles Marineris and the Tharsis bulge. Although it has no surface water, using planet-sculpting tools reveals water underground.


  • In reality, Mars has two satellites: Phobos and Deimos. They are not depicted in the game since they are neither spherical nor comparable in size to the Moon, Ganymede or Titan.
  • When terraformed to T-3, Mars is covered in red grass, much like H. G. Wells's fictional depiction in his novel The War of the Worlds.
  • The in-game version lacks the well-known "face." This is accurate because the real formation is very small relative to the planet.
