How do you breathe in space?

 Q:   Ask a Question about How do you breathe in space?       
How do you breathe in space? You cannot breathe in the vacuum of space because there is no air. Oxygen is the gas we need to stay alive, and it forms an important part of the air we breathe. AII space missions have to carry their own air supply.

Pure oxygen was used on the earliest space flights, but after a tragic fire it was realized that pure oxygen was too dangerous. Spacecraft and space stations now carry supplies of air instead.

When astronauts go on a 'space walk' they wear a space suit that provides them with air at the correct pressure, while still allowing them to move freely.
