Fuel is the propellant for Mars rocketships. It is produced via the Sabatier reaction, breaking down water from ice into oxygen and hydrogen via electrolysis. The resulting hydrogen is combined with carbon dioxide from the atmosphere to create small amounts of water and methane fuel. The amount of fuel (and thrust) needed to escape the planet’s orbit is much lower than what’s needed to escape Earth, due to Mars being smaller (only having 0.375 times the gravitational pull of Earth), and having a much thinner atmosphere.

Inputs and Outputs


Fuel is not a direct gameplay input into any of the items in the colony, but is used for Colony Development.
