A human can survive roughly three weeks without food, three days without water, and only three minutes without oxygen.

The Martian oxygen is produced via the Sabatier reaction used in the creation of the rocket fuel on Mars, breaking down water from ice into oxygen and hydrogen via electrolysis, then capturing this oxygen to be stored and used by the astronauts.

Initially, greenhouses will produce negligible quantities of oxygen compared to what’s being consumed, but larger future facilities may produce enough to be another source of oxygen for the colony.


Martia tokens can be staked to receive a share of the 20,000 Oxygen tokens awarded each hour.
