How Do We Breathe in Space
There is no air in space, so space missions must bring their own oxygen
Early missions used pure oxygen, but it was unsafe, so modern spacecraft use normal air mixtures
During spacewalks, astronauts wear spacesuits that supply oxygen and keep the right pressure so they can breathe and move safely
