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.
Relevance for life
Oxygen can be produced in situ:
- in greenhouses by plants.
- by reduction of carbon dioxide from the martian atmosphere
- by reduction of oxide minerals
- by electrolysis of water
- Propellant. Oxygen is often chosen as an oxidizer for chemical propulsion.
- Atmospheric component. Standard atmosphere contains 21% Oxygen.
- Chemical reagent
