10. How will we be sure that we won't run out of oxygen while in space? Will there be an emergency supply? (RR) (A K2S Question)

Typically, additional oxygen is carried with any mission, just to be sure we don't run out. Eventually we would run out if we somehow lost all the oxygen through a leak, or the systems that make the oxygen failed. But remember, when we fly humans in space we always have systems that have multiple backup systems, so that if something fails we are ready with a backup.
