NASA: Oxygen-producing Device on Mars Performed above Expectations
It is designed to change, or convert, carbon dioxide captured from the Mars atmosphere into oxygen.

NASA: Oxygen-producing Device on Mars Performed above Expectations
The instrument works through a process called electrolysis.

NASA: Oxygen-producing Device on Mars Performed above Expectations
Carbon dioxide makes up about 95 percent of the Martian atmosphere, NASA reports The rest is mostly molecular nitrogen and argon.

NASA: Oxygen-producing Device on Mars Performed above Expectations
But future exploration of Mars and possibly other planets by humans will require a large supply of oxygen.

NASA: Oxygen-producing Device on Mars Performed above Expectations
NASA has said the chemical element will be necessary for astronauts to breathe and to produce rocket fuel for launches carried out from the Martian surface.
