What is Mars in Starfield?

Mars in Starfield is a colonised planet located in the Sol Sytem and focused on heavy mining and industry. Just like in real life, Mars is still a vast red desert. It has a thin carbon dioxide atmosphere, low temperatures, vast dust storms, and gravity a little over one third of Earth’s. Mars is currently under the jurisdiction of the Starfield United Colonies faction, providing a wealth of raw minerals and manufactured goods.

Mars features, resources, and climate

Mars has a cold climate, low gravity, a thin O2 atmosphere, making it fairly inhospitable to life on the surface. To cater for this much of the human presence is limited to Cydonia, and several other smaller settlements, including Fracking Stations, the Mars Mech Factory, and the Deep Mines.

  • Type: Rock
  • Gravity: 0.38 G
  • Temperature: Cold
  • Atmosphere: Thing CO2
  • Magnetosphere: None
  • Fauna: None

Mars has the following resources:

The first and oldest extra-planetary settlement in Stafield, Cydonia is a city that predates even most of the current in-game factions like the Starfield Freestar Collective faction and the Starfield Constellation faction.

Due to Mars’ lack of air, Cydonia is primarily situated underground and built around a mining facility. The city is highly industrial in nature, notably for factories and functional, if a little tired, look and feel. It’s one of the largest mining operations anywhere in civilised space. This vast supply of raw materials makes Cydonia a location of critical importance to the Starfield United Colonies faction, whose territory includes Mars.
