Alga producing oxygen

Relevance for life

The metabolism of human beings, animals and various microbes depends on oxygen. The atmosphere of Mars contains only 0.2 % 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
