Explanation:
Detailed explanation-1: -Most people can survive only a couple of minutes without oxygen, and low concentrations of oxygen can cause fatigue and blackouts. To ensure the safety of the crew, the ISS will have redundant supplies of that essential gas.
Detailed explanation-2: -Currently, astronauts use a process called electrolysis to get oxygen in space crafts, according to The Conversation. This means running an electrical current through water to separate the hydrogen and oxygen molecules (please do not try this at home!).
Detailed explanation-3: -NASA scientists know that for humans to travel through space, astronauts have basic needs. Astronauts must have oxygen, food, water, and rest.
