The oxygen in a spacecraft is recycled through a chemical process that removes the carbon from the carbon dioxide we breathe out. Very much the same as the underwater "re-breather" that allows a Scuba diver to stay underwater for hours without carrying massive air tanks.
A more difficult situation would be if the air were somehow lost to space. That would be harder. But if the air leak could be patched, they could boil the water on-board to replace much of the air. While there would be an imbalance of lack of nitrogen, and an excess of hydrogen, the only ill effects would be that they will talk funny until they can return home.
It is also possible that they could use some of the oxygen that is used for the engines, but having too much oxygen content can cause other problems. The air we normally breathe is only about 20% oxygen.

Astronauts produce oxygen in space using an onboard system called the Elektron system. This system electrolyzes water obtained from the spacecraft's systems or brought from Earth to generate oxygen and hydrogen. The oxygen is then released into the spacecraft's atmosphere for the astronauts to breathe.

How and what do the astronauts breathe on the space station?
Astronauts on the space station breathe a mixture of oxygen and nitrogen, similar to the air we breathe on Earth. The station has systems that generate and maintain this breathable atmosphere, including equipment to produce oxygen from water and remove carbon dioxide exhaled by the astronauts.
How does space give us oxygen?
Space itself does not produce oxygen. Oxygen is primarily produced on Earth through the process of photosynthesis by plants and algae, which convert carbon dioxide into oxygen using sunlight. Astronauts on space missions rely on oxygen supplies carried with them or generated through systems that produce oxygen from water.
Do they have oxygen in space?
While space itself does not have oxygen, astronauts have access to oxygen on space missions through systems that generate and regulate the supply of breathable air. This is necessary for them to survive in the vacuum of space.
What did astronauts use to breathe in outer space?
Astronauts wear spacesuits that are equipped with a life support system, which includes an oxygen supply for breathing. This system provides them with a controlled environment to breathe while they are in the vacuum of space.
Why does a space shuttle carry its own supply of oxygen?
A space shuttle carries its own supply of oxygen to sustain the astronauts' breathing when they are in space where there is no atmosphere. It ensures they have a continuous source of oxygen for respiration during the mission.

How will astronauts get oxygen out of space?
They need to take it with them. There is no oxygen in space
How do astronauts get oxygen in space?
Astronauts bring tanks of oxygen with them when they go into space. The space suits they use to make space walks also have small oxygen tanks on them.
How do astronauts get oxygen into space?
They carry it with them on board.
What type of oxygen is in outer space that make us use helmets?
There is no oxygen in space. Astronauts have to take oxygen with them.
Do astronauts wear space suites to protect themselves from sun rays or are used for oxygen?
yes. the space suit does protect astronauts for harmful rays from the sun
Canwe breathe in space?
No, we cannot breathe in space because the oxygen level is very low. astronauts have to carry oxygen tanks to space.
Why do you need spacesuit and oxygen tank?
Spacesuits and oxygen tanks are needed in space because there is no atmosphere to provide oxygen for astronauts to breathe. Spacesuits also protect astronauts from extreme temperatures, radiation, and micrometeoroids. Without these, astronauts would not be able to survive in the harsh conditions of space.
What do astronauts use in space?
A suit, a rocket or brought oxygen maybe?
What is used in a space suit to keep astronauts on the moon?
gravity and oxygen
Why astronauts wear space suits outside spacecraft?
If they don't they will suffocate from lack of oxygen in space.
