Actualy that was a stupid question...
Astronauts brought an oxygen tank to the moon to breathe in the lunar environment, as there is no breathable atmosphere on the moon. The tank provided the necessary oxygen for astronauts to survive while conducting missions on the moon's surface.
Spacecraft need an internal oxygen supply to provide a breathable atmosphere for astronauts during space travel. Since there is no oxygen in space, spacecraft must carry their own supply to support human life. This ensures that astronauts have the necessary oxygen to breathe and carry out their activities while 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.
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.
Space suits: to protect astronauts from extreme temperatures, micrometeoroids, and provide oxygen. Extravehicular Mobility Units (EMUs): for spacewalks to enable astronauts to move and work outside the spacecraft. Tether systems: to keep astronauts connected to the spacecraft while working in space.
Astronauts wear spacesuits due to the absence of pressure in space. They need to maintain the pressure level on Earth by isolating themselves from actual space. For the helmets: there is no oxygen in space. Humans require oxygen to live, inhaling it through their nose and mouth. Therefore if they do not wear helmets, they will die instantly from loss of oxygen.
Astronauts wear specially made suits, called spacesuits, to protect them from the harsh conditions of space, such as extreme temperatures, vacuum, and radiation. The suits also provide oxygen, regulate temperature, and supply water. They are designed to keep astronauts safe and comfortable while they work outside the spacecraft.

Yes, astronauts carry oxygen supplies when they go into space, but they don't use traditional oxygen cylinders like those found on Earth. Instead, they rely on life support systems in their spacesuits and spacecraft that recycle and provide breathable air. These systems ensure a continuous supply of oxygen while also removing carbon dioxide exhaled by the astronauts, maintaining a safe and habitable environment in the vacuum of space.
Astronauts breathe using the life support systems on their spacecraft or spacesuits. These systems provide a controlled supply of oxygen for them to breathe while in space. Inside the spacecraft, the air is managed to ensure astronauts have a safe and breathable atmosphere.
