Oxygen (periodic table symbol: O8) is a chemical element that can be found in the atmosphere and in most minerals on Mars. Almost half of the mass of the Martian crust is Oxygen, bound up in various minerals.

Alga producing oxygen

Relevance for life

The metabolism of human beings, animals and various microbes depends on oxygen. The atmosphere of Mars contains only 0,15 % oxygen, which is not enough to support animal or human life.

Production

Oxygen can be produced in situ:

Uses

  • Propellant. Oxygen is often chosen as an oxidizer for chemical propulsion.
  • Atmospheric component. Standard atmosphere contains 21% Oxygen.
  • Chemical reagent
