The term '''Rover''' as used here describes any all-terrain vehicle designed to traverse the surface of a planet, moon, or asteroid. It allows exploring the surface on a variety of places, collecting and examining [[Minerals]], taking photos. The first rover (''Lunokhod 1'') was unmanned and remote controlled on [[moon|Earth's Moon]] in 1970. During the Apollo missions in the 1970s rovers have been used manned to extend the exploration range of the crew. It was not until 1997 that the first rover landed successfully on [[Mars]].

Oxygen

Abundance: 0.15% atmosphere 46,6% crust


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
